Japanese Patent Laid-Open No. 2001-22644

  However, in the game device disclosed in Patent Document 1, although the type of game can be distinguished by the save icon, the situation of the game in the save data cannot be distinguished. That is, when there are two save data with different game situations for the same game, the two save data cannot be distinguished by the save icon. In addition, although there were things that could distinguish the approximate game situation by displaying the player character level and the game area name in the vicinity of the save icon, there was no visual interest, The player could not distinguish at a glance.

  Further, not only a save icon but also a game image during game play cannot be displayed so that the game situation can be recognized at a glance. For example, conventionally, there has been a game apparatus that notifies a player of a game situation by displaying a status screen that indicates the level of the player character and the like, but the player cannot recognize the game situation at a glance.

  SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a game apparatus and a game program for displaying an image that can easily distinguish a game situation at a glance.

A first invention of the present invention is a game device (14) for displaying a predetermined image (save icon image or player character hat image) relating to a game on a display device (television 12). The game device includes a game data storage means (main memory 34), a first parameter determination means (S22 (abbreviation of step 44; the same applies hereinafter)), a second parameter. A determining means (S44), a first contribution degree determining means (S44), a second contribution degree determining means (S44), a display color determining means (S46 or S16), and a display control means (S48 or S18) are provided. The game data storage means stores game data that changes depending on the game play. The first parameter determining means determines the first parameter with reference to the game data stored in the game data storage means. The second parameter determination means determines a second parameter different from the first parameter with reference to the game data stored in the game data storage means. The first contribution degree determining means is a parameter used in the game process and based on the value of the first parameter indicating the game situation, the degree to which the predetermined first color (parameter related color) contributes to the display color of the predetermined image. A first contribution degree is determined. The second contribution degree determination means is a parameter used in the game process and a second color (parameter related color) different from the first color based on a value of a second parameter indicating a game situation different from the first parameter. 2nd contribution degree which shows the degree which contributes to a display color is determined. The display color determining means determines the display color by determining a ratio between the first color and the second color based on the first contribution and the second contribution. The display control means displays a predetermined image on the display device using the display color.
For example, the first parameter determining means sets a value of certain data of the game data stored in the game data storage means as the first parameter as it is, and the second parameter determining means is a different one of the game data stored in the game data storage means. The data value may be set as the second parameter as it is.
The first parameter determining means detects the number of data satisfying a predetermined condition among the game data stored in the game data storing means and sets the number as the first parameter. The second parameter determining means is the game data storing means. Of these game data, the number of data satisfying another condition may be detected and set as the second parameter.
In addition, the first parameter and the second parameter can be various values generated by different rules with reference to the game data stored in the game data storage means.
The game data storage means includes both one that temporarily stores game data during execution of game play and one that stores game data in a nonvolatile manner when the player instructs to save.
The predetermined image is, for example, a save icon or a hat image of a player character as in an embodiment described later, but may be a background image of a game or an image in a status display. Any image can be used as long as it is displayed on the game screen.

  In the second invention, a first game character (target character) displayed using the first color and a second game character (target character) displayed using the second color appear in the game. May be. At this time, the first parameter indicates the number of first game characters that satisfy a predetermined condition (a condition of being acquired by the player character). The second parameter indicates the number of second game characters that satisfy a predetermined condition. The first contribution determination means determines the first contribution to a larger value as the number of first game characters is larger. The second contribution degree determining means determines the second contribution degree to a larger value as the number of second game characters is larger. The display color determining means sets the second color so as to approach the first color when the first contribution is larger than the second contribution, and when the second contribution is larger than the first contribution. The ratio of the first color and the second color is determined so as to approach each other.

  In the third invention, the display color determining means determines the first contribution based on the first parameter and the color value representing the first color, and the color representing the second parameter and the second color. The second contribution may be determined based on the value.

In the fourth invention, the game device includes a first color primary color value storage means (main memory 34, correspondence table area 66) and a second color primary color value storage means (main memory 34, correspondence table area 66). May be further provided. The first color primary color value storage means stores a first primary color value, a second primary color value, and a third primary color value (RGB value) representing the first color. The second color primary color value storage means stores a first primary color value, a second primary color value, and a third primary color value representing the second color. At this time, the first contribution degree determination means includes a first contribution degree A indicating the degree that the first color contributes to the first primary color value of the display color of the predetermined image, and the second contribution of the display color of the predetermined image. A first contribution B indicating the degree of contribution to the primary color value and a first contribution C indicating the degree of contribution of the first color to the third primary color value of the display color of the predetermined image are determined. The second contribution degree determining means sets the second contribution A indicating the degree of contribution of the second color to the first primary color value of the display color of the predetermined image, and the second primary color value of the display color of the predetermined image. A second contribution degree B indicating the degree of contribution and a second contribution degree C indicating the degree to which the second color contributes to the third primary color value of the display color of the predetermined image are determined. The display color determining means determines the first contribution A based on the first parameter and the first primary color value of the first color, and the first contribution B based on the first parameter and the second primary color value of the first color. The first contribution C is determined based on the first parameter and the third primary color value of the first color, and the second contribution A is determined based on the second parameter and the first primary color value of the second color. The second contribution B is determined based on the second parameter and the second primary color value of the second color, and the second contribution C is determined based on the second parameter and the third primary color value of the second color.

  In the fifth invention, the game device may further include save data storage means (main memory 34 or memory card 18) and read means. The save data storage means stores game save data. The reading unit reads the save data stored in the save data storage unit. At this time, the first parameter determination unit and the second parameter determination unit determine the first parameter and the second parameter with reference to the save data read by the reading unit. The display control means displays an image of a save icon representing game save data using a display color.

  In the sixth invention, the predetermined image may be an image displayed during game play. The image displayed during the game play may be, for example, a background image of the game, an image of a frame of the display area, or the like in addition to the hat image of the player character. At this time, when the game data changes during the game play, the first parameter determination means determines the first parameter based on the changed game data. When the game data changes during game play, the second parameter determination means determines the second parameter based on the changed game data. The first contribution determination means determines the first contribution based on the changed first parameter when the first parameter changes. The second contribution determination means determines the second contribution based on the changed second parameter when the second parameter changes. When the first contribution or the second contribution is changed, the display color determination unit determines the display color based on the first contribution and the second contribution after the change.

  In the seventh invention, the first game character and the second game character may appear in the game. At this time, the first parameter indicates the number of first game characters that satisfy a predetermined condition. The second parameter indicates the number of second game characters that satisfy a predetermined condition.

  In the eighth invention, the display color determining means approaches the first color when the first contribution is larger than the second contribution, and the second contribution becomes the first contribution. The ratio between the first color and the second color is determined so as to approach the second color when the comparison is larger.

  In the ninth invention, the game apparatus may further include basic image storage means for storing a basic image (FIG. 10) in which a colored portion is defined. At this time, the display control means displays an image in which the color determined by the display color determination means is set in the colored portion as a predetermined image.

  A tenth aspect of the invention is a game device (14) for displaying an image of a save icon representing game save data on a display device (television). The game device includes parameter determining means (S44), display color determining means (S46), and display control means (S48).

Therefore, the game situation can be distinguished at a glance more easily than reading with characters.

  According to the second aspect, the display color of the predetermined image changes according to the number of game characters that satisfy the predetermined condition. Further, the display color of the predetermined image is a color close to the first color if the number of game characters of the first color is large, and a color close to the second color if the number of game characters of the second color is large. That is, the display color of the predetermined image changes according to the color of the game character having a large number. Therefore, according to the second aspect of the invention, it is possible to inform the player of the approximate number of game characters that satisfy the predetermined condition so that the player can understand at a glance.

  According to the third aspect, it is possible to calculate the contribution according to the parameter value.

  According to the fourth aspect, since the RGB value of the display color is determined in accordance with the ratio of the contribution calculated for each RGB value, even if the color is expressed by the three primary colors of the RGB value The display color can be determined in a form that accurately reflects the calculated contribution.

  According to the fifth aspect, the player can determine the game situation indicated by the save data by the color of the save icon. Therefore, the contents of the save data can be intuitively recognized.

  According to the sixth aspect, the player can grasp the current game situation by viewing a predetermined image even during game play.

  According to the seventh aspect, since the number of game characters is reflected in the display color of the predetermined image, the player can intuitively recognize the number of game characters by viewing the predetermined image.

  According to the eighth aspect, the magnitude of each contribution can be accurately reflected when determining the display color of the predetermined image.

  According to the ninth aspect, it is possible to easily generate a predetermined image whose color changes in accordance with the display color.

  According to the tenth aspect, the game device can cause the player to recognize the game situation indicated by the save data by the color of the save icon. Therefore, the player can distinguish at a glance more easily than reading the contents of the save data with characters.

FIG. 1 is an external view showing a configuration of a game system according to an embodiment of the present invention, and FIG. 2 is a block diagram thereof. As shown in FIGS. 1 and 2, the game system includes a game apparatus 14, an optical disc 16, a memory card 18, a controller 20, and a television 12 (including the speaker 50 shown in FIG. 2). The optical disk 16 and the memory card 18 are detachably attached to the game apparatus 14. The controller 20 is connected to one of a plurality of (four in FIG. 1) controller port connectors provided in the game apparatus 14. In other embodiments, communication between game device 14 and controller 20 may be performed by wireless communication without using a communication cable. In addition, the television 12 and the speaker 50 are connected to the game apparatus 14 by an AV cable or the like. Hereinafter, each part in the game system according to the present invention will be described in detail. Hereinafter, a general operation in the game system will be described with reference to FIG.

  An optical disc 16 as an example of an external storage medium is, for example, a DVD-ROM, and stores data related to a game such as a game program and character data in a fixed manner. When the player plays a game, the optical disk 16 is mounted on the game apparatus 14. The means for storing the game program or the like is not limited to the DVD-ROM, and may be a storage medium such as a CD-ROM, MO, memory card, ROM cartridge, or the like. The memory card 18 is constituted by a rewritable storage medium such as a flash memory, for example, and stores data such as save data in a game (see FIG. 3 described later).

  The game apparatus 14 reads a game program recorded on the optical disc 16 and performs a game process. The controller 20 is an input device for a player to make an input related to a game operation, and has a plurality of operation switches. The controller 20 outputs operation data to the game device 14 in response to pressing of the operation switch by the player. The television 12 displays the image data output from the game device 14 on the screen. The speaker 50 is typically built in the television 12 and outputs a game sound output from the game apparatus 14.

  Next, the configuration of the game apparatus 14 will be described. In FIG. 2, in the game apparatus 14, a CPU 22 and a memory controller 40 connected thereto are provided. Further, in the game apparatus 14, the memory controller 40 includes a graphics processing unit (GPU) 24, a main memory 34, a sub memory 38 via a digital signal processing circuit (DSP) 36, and various interfaces (I / F). ) 42-52. The memory controller 40 controls data transfer between these components.

  When starting the game, first, the disk drive 54 drives the optical disk 16 mounted on the game apparatus 14. The game program stored in the optical disc 16 is read into the main memory 34 via the disc I / F 52 and the memory controller 40. When the CPU 22 executes the program on the main memory 34, the game is started. After the game is started, the player inputs a game operation or the like to the controller 20 using the operation switch. In accordance with the input by the player, the controller 20 outputs operation data to the game device 14. Operation data output from the controller 20 is input to the CPU 22 via the controller I / F 42 and the memory controller 40. The CPU 22 performs a game process according to the input operation data. Game data generated and changed in the game process is temporarily stored in the main memory 34. The GPU 24 and the DSP 36 are used for generating image data in game processing. The sub memory 38 is used when the DSP 36 performs a predetermined process.

The GPU 24 includes a geometry unit 26 and a rendering unit 28, and is connected to a memory dedicated to image processing. This image processing dedicated memory is used as, for example, the color buffer 30 and the Z buffer 32. The geometry unit 26 performs arithmetic processing on the coordinates of a solid model (for example, an object composed of polygons) related to an object or a figure placed in a game space that is a virtual three-dimensional space. Enlargement / reduction, transformation, and conversion from coordinates in the world coordinate system to coordinates in the viewpoint coordinate system and screen coordinate system are performed. The rendering unit 28 generates a game image by writing color data (RGB data) for each pixel in the color buffer 30 for the three-dimensional model projected on the screen coordinates based on a predetermined texture. The color buffer 30 is a memory area secured for holding game image data (RGB data) generated by the rendering unit 28. The Z buffer 32 is a memory area reserved for holding depth information from the viewpoint that is lost when converting from the three-dimensional viewpoint coordinates to the two-dimensional screen coordinates. The GPU 24 generates image data to be displayed on the television 12 using these, and outputs them to the television 12 via the memory controller 40 and the video I / F 44 as appropriate. Note that audio data generated in the CPU 22 when the game program is executed is output from the memory controller 40 to the speaker 50 via the audio I / F 48. In the present embodiment, a hardware configuration in which a memory dedicated for image processing is separately provided is used. However, the present invention is not limited to this. ) May be used.

  FIG. 3 is a diagram schematically showing a memory area of the memory card 18. The memory card 18 is provided with a plurality of save data areas. In FIG. 3, at least three save data areas, ie, a first save data area 60a, a second save data area 60b, and a third save data area 60c are provided. Different save data can be stored in each save data area. Save data indicating different situations for the same game can be stored in each area, and save data for different games can be stored in each area. One type of game serial number and one type of save data are stored in the save data area. The game serial number is information for identifying the game type, and a different number is assigned to each game type. The save data includes data necessary for restarting the game. The save data is data indicating the game situation. Note that two save data with different game situations are stored in separate save data areas. For example, the first save data area 60a may store save data for different game situations in the same type of game as the second save data area 60b. In the following description, the save data areas 60a to 60c are simply referred to as the save data area 60 when it is not necessary to distinguish them.

  FIG. 4 is a diagram schematically showing the main memory 34 of the game apparatus 14 and the memory area of the memory card 18. In the main memory 34, a game data area 62, a game program area 64, and a correspondence table area 66 are provided. The game data area 62 is an area for storing various data indicating the game situation, and this data is sequentially changed by the CPU 22 by executing the game process. The game program area 64 is an area for storing a game program read from the optical disc 16. The correspondence table area 66 is an area for storing a correspondence table described later.

  The player can save at a predetermined timing during the game. When the save instruction is given by the player, the game apparatus 14 transfers the contents of the game data area 62 of the main memory 34 to the save data area 60 of the memory card 18 via the memory controller 40 and the memory I / F 46. (See arrow shown in FIG. 4). A part of the data in the game data area 62 of the main memory 34 may be transferred to the save data area 60 of the memory card 18. Further, the timing at which the save is performed may be any timing. In addition to the case where the instruction is given by the player, for example, the save may be automatically performed when a predetermined condition in the game progress is satisfied. Good. On the other hand, when the game is started in the game situation indicated by the save data, the game apparatus 14 stores the contents of the save data area 60 of the memory card 18 via the memory controller 40 and the memory I / F 46 prior to the start of the game. The data is read into the game data area of the main memory 34.

Next, a game process performed in the game device according to the present invention will be described. First, the outline of the game process will be described. In the present invention, images relating to the game are displayed in different colors depending on the game situation. The image related to the game is, for example, an image of a save icon representing save data, an image of a part of a player character operated by the player, or the like. In the present embodiment, the save icon and the image of the player character's hat are displayed in different colors depending on the game situation. Thus, the player can intuitively grasp the game situation by viewing these images. Specifically, before the game is started, the game situation indicated by the save data can be determined by the color of the save icon. That is, the player can determine which save data is used to play the game from the color of the save data. Further, during the game, the current game situation can be determined by looking at the hat of the player character. That is, the player can determine a rough progress of the game and a degree of achievement by looking at the hat of the player character. As described above, according to the present invention, the player can grasp the game situation at a glance.

  In the present embodiment, a game in which a player character plays by acquiring a plurality of characters will be described as an example. In this game, a plurality of types of characters (hereinafter referred to as target characters) that can be acquired by the player character appear. The target character has a different color for each type. Specifically, eight types of target characters displayed in red, green, blue, yellow, brown, black, white, and gray, respectively, appear in this game. In this game, as the game progresses, more target characters are acquired, and more types of target characters are acquired. Accordingly, by looking at the type and number of acquired target characters, it is possible to determine the progress of the game, the degree of achievement, the game situation at that time, and the like. Here, it is assumed that the color of the save icon and the color of the hat of the player character change according to the type and number of target characters acquired. For example, when a large number of red target characters (red characters) are acquired, the color of the save icon and the hat of the player character is a reddish color. Further, when a large number of blue target characters (blue characters) are acquired, the color of the save icon and the hat of the player character becomes a blue color. Thus, the player can grasp at a glance the game situation regarding the number and type of the acquired target characters by looking at the save icon and the color of the player character's hat.

  Next, details of the game processing performed in the game device according to the present embodiment will be described. FIG. 5 is a diagram showing the contents of the save data in the present embodiment. The save data area 60 of the memory card 18 includes a game serial number and acquired character number data. The acquired character number data is data indicating the number of target characters acquired when the save data is saved. Here, in the present embodiment, data indicating the number of acquired red target characters (red characters) is set as the first parameter. Further, data indicating the number of acquired green target characters (green characters) is set as the second parameter. Similarly, data indicating the number of acquired blue target characters (blue characters) is set as a third parameter, and data indicating the number of acquired yellow target characters (yellow characters) is set as a fourth parameter. Data indicating the number of brown target characters (brown characters) set and acquired is set as a fifth parameter, and data indicating the number of black target characters (black characters) acquired is set as a sixth parameter. Data indicating the number of acquired white target characters (white characters) is set as a seventh parameter, and data indicating the number of acquired gray target characters (ash characters) is set as an eighth parameter. Set.

Next, the correspondence table in the main memory 34 will be described. The correspondence table is used to determine the color of the save icon and the player character's hat. FIG. 6 is a diagram illustrating an example of the correspondence table. As shown in FIG. 6, the correspondence table is a table in which parameters are associated with colors related to the parameters (parameter-related colors described later). Note that “color name” in FIG. 6 is described for ease of understanding and may not be included in the actual table. In the present embodiment, colors are expressed using the three primary colors RGB. In this embodiment, each RGB value takes an integer value from 0 to 255. In the correspondence table, each parameter is associated with an RGB value representing one type of color. Here, in the present embodiment, the color associated with each parameter is the display color (display color in the game image) of the target character whose acquisition number is indicated by the parameter. For example, red (RGB value (255, 0, 0)) is associated with the first parameter indicating the number of red characters (characters whose main body is represented in red in the game image). The color relating to the parameter is used to determine the display color of the save icon and the hat of the player character. Hereinafter, the color defined in the correspondence table and associated with each parameter is referred to as “parameter related color”. Furthermore, in the following, the parameter related color related to the nth parameter (n is an integer) is referred to as the nth parameter related color. For example, the first parameter-related color that is the parameter-related color related to the first parameter is red.

  Next, a flow of game processing performed in the game device according to the present embodiment will be described. When the power of the game apparatus 14 is turned on, the CPU 22 of the game apparatus 14 executes a startup program stored in a boot ROM (not shown) and initializes each unit such as the main memory 34. Then, the game program stored in the optical disc 16 is read into the main memory 34 via the disc drive 54, and execution of the game program read into the main memory 34 is started. The flowchart shown in FIG. 7 shows processing after the above processing operation. Note that the processing shown in this flowchart is performed as a cooperative operation of the CPU 22 and the GPU 24. However, for example, almost all of the processing can be performed only by the CPU 22.

  FIG. 7 is a main flowchart of the game process performed in the game device according to the present embodiment. First, in step 10 ("step" in the figure is simply abbreviated as "S"), a save data selection process is performed. The save data selection process is a process for causing the player to select save data to be used for a game to be played. Details of the save data selection process will be described below.

  FIG. 8 is a flowchart showing details of step 10 shown in FIG. In the save data selection process, first, in step 40, one save data is read from the save data area 60 of the memory card 18 to the game device 14. In step 40, save data that has not been read in the previous step 40 is read. In subsequent step 42, it is determined whether or not the game type of the save data read out in step 40 is the same as the game type of the game program stored in the optical disc 16 currently mounted on the game apparatus 14. Is done. This determination is made based on whether or not the game serial number included in the save data is the same as the game serial number stored on the optical disc 16. If it is determined in step 42 that the game types are not the same, the process returns to step 40. That is, another save data is read from the memory card 18.

  On the other hand, if it is determined in step 42 that the game types are the same, the processing in steps 44 to 48 is performed. Here, it is assumed that the optical disk storing the game program of the game in which the target character appears is mounted on the game apparatus 14. Therefore, if the save data of the game is read in step 40, steps 44 to 46 are performed. The processing in steps 44 to 46 is processing for displaying a save icon in a different color according to the type and number of the acquired target characters indicated in the save data.

  In step 44, each parameter is determined with reference to the save data read in step 40, and the contribution is calculated based on each parameter. Here, the contribution degree is an index indicating the degree to which the parameter-related color contributes to the display color of the save icon (and the player character's hat). The parameter-related color is a color associated with a parameter in the correspondence table. The contribution is calculated for each parameter. That is, the first contribution is calculated based on the first parameter, and the second contribution is calculated based on the second parameter. In this embodiment, since eight parameters are set in the correspondence table, eight contributions are calculated in step 44. In the game device of the present embodiment, colors are expressed using the three primary colors of RGB. Each of the contributions described above relates to the R contribution for the R value, the G contribution for the G value, and the B value. B contribution degree.

In the present embodiment, the degree of contribution is a value obtained by multiplying the parameter value (that is, the number of acquired target characters) by the RGB value of the parameter-related color corresponding to the parameter. Specifically, the value of the i-th parameter (i is an arbitrary integer from 1 to 8) is Ni, and the RGB value of the parameter-related color corresponding to the i-th parameter (that is, the i-th parameter related color) is (Ri , Gi, Bi), the contribution Mi regarding the i-th parameter is calculated by the following equation (1).
Mi = (Ni × Ri, Ni × Gi, Ni × Bi) (1)
As shown in Expression (1), the contribution Mi in the present embodiment is configured by three contributions for each of the RGB values. That is, Ni × Ri is the contribution (R contribution) for the R value, Ni × Gi is the contribution (G contribution) for the G value, and Ni × Bi is the contribution (B contribution) for the B value. is there. According to Expression (1), as the number of acquired target characters increases, the contribution degree of the parameter-related color corresponding to the color of the target character increases.

  In step 46 subsequent to step 44, the display color of the save icon is determined based on each contribution calculated in step 44. A method for determining the display color of the save icon in the present embodiment will be described below.

８である。式（２）によって算出される（Ｘｒ，Ｘｇ，Ｘｂ）は、セーブアイコンの表示色のＲＧＢ値の比を表す。つまり、式（２）によって、セーブアイコンの表示色のＲＧＢ値の比が決定される。 In the present embodiment, first, the following equation (2) is calculated using the contribution calculated in step 44.

... (2)
Here, Mri is the R contribution (that is, Ni × Ri in the formula (1)) of the contribution Mi, and Mgi is the G contribution (that is, the formula (1) in the contribution Mi). Ni × Gi), and Mbi is the B contribution of the contributions Mi (that is, Ni × Bi in equation (1)). Moreover, in Formula (2), n is the number of parameters. In this embodiment, n =
8. (Xr, Xg, Xb) calculated by the equation (2) represents a ratio of RGB values of the display color of the save icon. That is, the ratio of the RGB values of the display color of the save icon is determined by the equation (2).

As a result of the calculation of the above formula (2), each value of (Xr, Xg, Xb) can be a value exceeding 255. Therefore, since each value of (Xr, Xg, Xb) cannot be used as it is as the RGB value of the display color of the save icon, conversion is performed so that the maximum value of (Xr, Xg, Xb) is 255. There is a need to do. Therefore, in the present embodiment, the following equation (3) is calculated after the equation (2). Thereby, the RGB value (Yr, Yg, Yb) of the display color of the save icon is determined.
Yr = 255 × Xr / Xmax
Yg = 255 × Xg / Xmax
Yb = 255 × Xb / Xmax (3)
In Formula (3), Xmax is the maximum value among (Xr, Xg, Xb) calculated by Formula (2). Therefore, for example, when the maximum value among Xr, Xg, and Xb is Xr as a result of the calculation of Expression (2), Yr = 255, Yg = 255 × Xg / Xr, Yb = 255 × Xb / Xr Become. The calculation result using the degree of contribution can be expressed by a value from 0 to 255 by Expression (3).

  In step 48 following step 46, the save icon is displayed in the display color determined in step 46. By one step 48, one save icon is displayed. At this time, characters indicating the game status of the save data (player character level, play time, etc.) may be written along with the save icon. In the subsequent step 50, it is determined whether or not there is saved data in the memory card 18 that has not been read yet in the processing loop of steps 40 to 48. If it is determined in step 50 that there is saved data in the memory card 18 that has not yet been read, the process returns to step 40. The processes in steps 40 to 48 are repeated until all the save data in the memory card 18 is read. On the other hand, if it is determined in step 50 that there is no saved data in the memory card 18 that has not yet been read, the process in step 52 is performed. That is, in step 52, selection of save data by the player is accepted. That is, after the save icons of all the save data in the memory card 18 are displayed on the screen, the player can perform an operation of selecting the save data. In the above steps 40 to 52, the save data selection process ends.

  FIG. 9 is a diagram showing an example of a screen for selecting save data. In FIG. 9, three save icons, spherical save icons 70, 72, and 74, are displayed. For example, when the player designates one of the three save icons using the cross key provided in the controller 20 and starts the game using the save data indicated by the designated save icon, the player provides the save icon. The save icon is selected by pressing the button. In FIG. 9, the save icon that is a selection candidate (the save icon being specified by the player) is displayed slightly larger than the others. In FIG. 9, the rightmost save icon 74 is a selection candidate. In addition, in a window 76 arranged below each save icon 70, 72, and 74, a part of the contents of the save data for the save icon that is a selection candidate is displayed. In FIG. 9, “DATA3” which is information for identifying the save data, “level: 5” indicating the level, and “treasure: OO” indicating the acquired item are displayed.

Here, the save icons 70, 72, and 74 are displayed with colors. In FIG. 9, the color difference is represented by diagonal lines. The color of each save icon 70, 72, and 74 is the display color determined in step 46 described above. In the display color determination method using the above formulas (1) to (3), the parameter related color included in the display color of the save icon is set so that the ratio of the parameter related color corresponding to the target character having a large number of acquired characters increases. Is determined. For example, a save data save icon indicating a game situation in which a large number of red characters have been acquired is displayed in a reddish color. Therefore, the player can determine which type of acquired character is acquired by the color of the save icon. Information on the number of acquired target characters may be displayed in the window 76 as characters. However, by expressing the information in the color of the save icon, the player can understand more than when displaying the information in characters. The information can be presented easily and intuitively.

  In this embodiment, only the save icon of the same type of game as the game of the game program stored on the currently installed optical disc 16 is displayed. However, in other embodiments, the currently installed game icon is displayed. A save icon of a game other than the game of the game program stored on the optical disc 16 may be displayed. The display color of the save icon may be any color. At this time, the display of the save icon may be changed for each game type so that the player can identify the game type. For example, the shape of the save icon may be changed according to the type of game, an image representing the type of game may be displayed in the center of the spherical save icon, or the game name is displayed near the save icon. May be.

  The save icon image may be generated by any method, but in this embodiment, the save icon image is generated using a texture. FIG. 10 is a diagram illustrating a texture used for a save icon image in the present embodiment. In the present embodiment, a save icon image is generated by mapping the texture shown in FIG. 10 onto a spherical object. That is, the circular portion near the center of the texture shown in FIG. 10 is mapped so as to correspond to the circular portion in the upper left portion of the save icon shown in FIG. Here, a colored portion (shaded portion shown in FIG. 10) is defined in the texture. The colored portion is a portion where the display color determined in step 46 is set. That is, the color of the colored portion of the texture is set to the display color determined in step 46. As described above, in this embodiment, the color of the save icon is changed by changing the color of the texture mapped to the spherical object in accordance with the display color determined in step 46. Note that each pixel in the colored portion of the texture shown in FIG. 10 may have predetermined data, and the display color determined in step 46 may be corrected with the data to determine the display color of the save icon. . For example, if each pixel in the colored portion of the texture has gradation data and the display color luminance determined in step 46 is corrected with the gradation data to determine the display color of the save data, The icon is represented by a color with a gradation instead of a single color.

  Returning to the description of FIG. 7, after the save data selection process in step 10, in step 12, the game is set based on the save data selected in step S <b> 52. That is, the game parameters at the start of the game are set according to the contents of the save data selected in the save data selection process. For example, game parameter values such as the number and type of target characters acquired are set. After step 12, the game is started. After the game is started (steps 14 to 30), game processing is performed according to the operation by the player, and the game proceeds.

In step 14, a game process is performed based on an operation by the player. For example, the player character and the target character are moved in the game space in response to an operation by the player. In the following step 16, the color of the player character image (hat) is determined. In this embodiment, the hat color of the player character is determined as the display color of the save data determined in step 46 described above. In the subsequent step 18, a game image is displayed. In this game image, the hat of the player character is displayed in the color determined in step 16.

  In step 20 following step 18, it is determined whether or not the number of acquired target characters has changed. The process of step 20 is a process of determining whether or not the first to eighth parameters have been changed. Specifically, it is determined whether or not the player character has newly acquired the target character and whether or not the player character has lost the target character. If it is determined in step 20 that the number of target characters that have been acquired has changed, processing in steps 22 and 24 is performed. That is, in step 22, the content of the target character count data in the main memory 34 is changed. Specifically, the parameter value corresponding to the target character whose number has changed among the parameters included in the target character number data in the main memory 34 is updated. In the following step 24, the color of the player character image (hat) is changed. The color after change is determined by performing the same processing as in steps 44 and 46 described above, using each parameter after being changed in step 22. Through the steps 22 and 24 described above, the hat color of the player character reflects the latest game situation. On the other hand, if it is determined in step 20 that the number of acquired target characters has not changed, the processes in steps 22 and 24 are skipped and the process in step 26 is performed.

  In step 26, it is determined whether or not to save the current game situation. The specific determination method in step 26 may be any method. For example, it may be determined whether or not saving is instructed by the player, or it may be determined whether or not a predetermined condition in the game progress is satisfied. If it is determined in step 26 that the current game situation is to be saved, the process in step 28 is performed. That is, in step 28, the save data is stored in the memory card 18. Specifically, the contents of the game data area 62 of the main memory 34 are transferred to the save data area 60 of the memory card 18 (see the arrow shown in FIG. 4). On the other hand, if it is determined in step 26 that the current game situation is not to be saved, the process in step 28 is skipped and the process in step 30 is performed.

  In step 30, it is determined whether or not to end the game. If it is determined in step 30 that the game is to be ended, the CPU 22 ends the game process shown in FIG. On the other hand, if it is determined in step 30 that the game is not to be ended, the process of step 14 is performed again. Thereafter, the processes in steps 14 to 28 are repeated until it is determined that the game is to be ended.

  As described above, according to the present embodiment, by displaying the save icon in a color reflecting the game situation, the player can grasp the game situation in the save data at a glance. Also, by displaying the image of the player character in a color reflecting the game situation, the player can grasp the current game situation at a glance.

  In the present embodiment, the game data indicating the type and number of the acquired target characters are set as parameter values as they are, and the colors of the images of the save icon and the player character (save icon, etc.) are changed. In the embodiment, the parameter used to determine the color of the save icon or the like may be any parameter that is determined with reference to the game data. Below, the example of a game using other parameters is explained as a modification of this embodiment.

First, a first modification will be described. In the first modification, the type of the target character is distinguished by attributes such as flame and water. In other words, the target character includes types such as a flame character that is a flame attribute and a water character that is a water attribute. FIG. 11 is a diagram showing a target character attribute table used in the first modification. The target character attribute table is a table in which target characters and their attributes are associated with each other. The target character attribute table is stored in a fixed manner on the optical disc 16 and is read and used in the main memory when the game is executed. In FIG. 11, in the target character attribute table, the character number for identifying the target character, the character name of the target character, the attribute (type), and the ability value (for example, physical strength, vitality, etc.) of the target character. It is associated. By referring to the target character attribute table, the game apparatus 14 can know the attribute from the target character.

  FIG. 12 is a diagram showing the contents of the save data in the first modification. As shown in FIG. 12, a character number for the acquired target character is stored as save data. In the first modification, the number of flame characters, the number of grass characters, and the number of water characters are set as parameters for the acquired characters included in the save data. In this case, the number of flame characters, the number of grass characters, and the number of water characters do not exist in the save data, so refer to the character number included in the save data and the above-mentioned target character attribute table to obtain. Processing is performed to calculate the number of flame characters, grass characters, and water characters, and each calculated value is set as a parameter.

  FIG. 13 is a diagram illustrating an example of a correspondence table in the first modification. In FIG. 13, as in FIG. 6, the correspondence table is a table in which parameters are associated with parameter-related colors corresponding to the parameters. However, in FIG. 13, the information indicated by each parameter is different from that in FIG. Therefore, the parameter-related colors associated with each parameter are also different from those in FIG. Here, in FIG. 13, the first parameter indicating the number of flame characters is associated with red representing the flame image. The second parameter indicating the number of grass characters is associated with green representing the grass image. The third parameter indicating the number of water characters is associated with a blue color representing an image of water. The fourth parameter indicating the number of electric characters is associated with yellow representing the image of electricity (lightning). The second parameter indicating the number of ground characters is associated with brown representing the ground (soil) image. Thus, the correspondence table is preferably set so that the parameter-related color associated with the parameter is a color that reminds the parameter. This is because the player can easily determine from the color of the save icon or the like which attribute character the player has acquired, that is, what kind of situation the game situation is. As shown in the first modified example, the color associated with each parameter in the correspondence table is not limited to the color directly related to the parameter, but the color indirectly related to the parameter (depending on the parameter). Color associated with the displayed information) may be associated.

  Next, a second modification will be described. In the second modification, a level is set for the acquired character. In the second modified example, the type of acquired character may not be defined. FIG. 14 is a diagram showing the contents of the save data in the second modification. The acquired character data includes the character name and level of the acquired acquired character.

FIG. 15 is a diagram illustrating an example of a correspondence table in the second modification. Also in FIG. 15, as in FIG. 6, the correspondence table is a table in which parameters are associated with parameter-related colors corresponding to the parameters. As shown in FIG. 15, in the second modification, the first parameter indicates the number of acquired characters of levels 1 to 10. The second parameter indicates the number of acquired characters of levels 11 to 20, the third parameter indicates the number of acquired characters of levels 21 to 50, and the second parameter is the number of acquired characters of levels 51 to 100. The second parameter indicates the number of acquired characters of level 101 or higher.

  As shown in FIG. 15, in the second modification, the parameter used to determine the color of the save icon or the like is the number of acquired characters in a predetermined range of levels. That is, as in the first modification, in the second modification, the parameters used for determining the color of the save icon or the like are not included in the acquired character data of the save data shown in FIG. In the second modification, when determining the display color of the save icon or the like, first, the value of each parameter used to determine the display color is calculated. Specifically, the game device 14 calculates the number of acquired characters for each range of levels from the level of each character data included in the acquired character data. In the second modification, the display color is determined using each parameter whose value is calculated as described above. Therefore, in the second modification, for example, before the process of step 44 in FIG. 8, it is necessary to perform a process of calculating the value of each parameter.

  In FIG. 15, the G component and B component of the RGB values of each parameter-related color are all “0”. Each parameter-related color differs only in the value of the R component. In this way, the parameter-related colors may all be similar colors. However, when the parameter-related colors are all similar colors, the above-described equations (1) to (3) cannot change the display color of the save icon or the like. That is, when parameter-related colors are set as in the table shown in FIG. 15, the RGB values (Yr, Yg, Yb) of the display color of the save icon are independent of the parameter values (what the parameter values are (Even if there is), it becomes (255, 0, 0). Therefore, in the second modification, the display color of the save icon or the like is determined by a method different from that in the above embodiment. Details will be described below.

Also in the second modified example, the degree of contribution is calculated as in the above embodiment. The calculation method of the contribution is the same as that in the above embodiment. That is, the contribution is calculated using the above formula (1). Furthermore, (Xr, Xg, Xb) is calculated by performing the calculation of the above equation (2) as in the above embodiment. Next, in the second modified example, the following expression (4) is calculated using (Xr, Xg, Xb).
Yr = Xr / Nall
Yg = Xg / Nall
Yb = Xb / Nall (4)
In Expression (4), Nall is the total sum of each parameter (in the second modified example, the first to fifth parameters). In the second modification, the value of Yr can be converted to a value of 255 or less by using Expression (4). In the second modification, the value of Yr increases as the proportion of acquired characters with a high level increases by using Expression (4). Accordingly, the player can determine the overall level of the acquired character by looking at the color of the save icon or the like.

In the second modification, (Yr, Yg, Yb) may be determined using the following equation (5) instead of the above equation (4).
Yr = 255 × Xr / Nmax
Yg = 255 × Xg / Nmax
Yb = 255 × Xb / Nmax (5)
In Equation (5), Nmax is the maximum value of each parameter (first to fifth parameters in the second modification). Even if the equation (5) is used, the same effect as in the case of the equation (4) can be obtained.

In the present embodiment, for example, a parameter indicating the number of red characters (characters whose main body parts are displayed in red) is associated with red as a parameter-related color, and a blue character (main body part is displayed). The parameter indicating the number of acquired characters) displayed in blue is associated with blue as a parameter-related color. That is, the main display color of the target character and the parameter related color associated with the parameter indicating the number of acquired characters are set to be the same color. However, the character display color and the parameter-related color do not necessarily have to be the same color. This is because, as long as the correspondence relationship between the parameter and the parameter-related color associated with the parameter is presented to the player in advance, the player can recognize the game situation by looking at the color of the save icon or the like. Because it can. Further, even if the corresponding relationship is not presented to the player in advance, the color of the save icon or the like changes if the game situation is different, so that the save icon of a different color has a different game situation. In addition, it is possible to recognize that save data having a similar color such as a save icon is similar to the save data. For this reason, the color recalled from the parameter and the parameter-related color may be completely different.

  In the present embodiment, parameters used for determining the color of the save icon or the like are stored in the memory card 18 as save data. Here, in another embodiment, the RGB value of the display color of the save icon may be stored in the memory card 18 as the save data together with the image data of the save icon. When the save data includes the RGB value of the display color of the save icon and the image data of the save icon, the display color determining process (steps 44 and 46 shown in FIG. 8) need not be performed at the start of the game. Further, even when a game program that does not include display color determination processing is started, the save icon display color RGB value and the save icon image data are read, and the save icons that have different colors depending on the game situation Can be displayed. In this case, the display color determination process needs to be performed when the save data is stored in the memory card 18 (for example, between step 24 and step 26 shown in FIG. 7).

  In the present embodiment, the case where the display color of the save icon and the player character image is changed according to the game situation has been described. Here, in another embodiment, the display color may be changed only for either the save icon or the player character image. In the present embodiment, the case where the color is expressed by the RGB value has been described, but the color may be expressed by YUV.

  The present invention can be used as a game device and a game program for the purpose of displaying an image that can easily distinguish a game situation at a glance.
