2. Description of the Related Art In a conventional race game or action game, a player generally operates one character for each player. For example, in a conventional race game, a race game is played by one player operating one car (one driver). In such a conventional racing game or action game, the motion of the character to be operated is determined only by the operation of the player. Therefore, a plurality of players cannot cooperate with each other to operate one character, and a plurality of players cannot feel a sense of solidarity.

Therefore, a technique has been considered in which two players cooperate to operate one character. For example,
The invention described in Japanese Patent Laid-Open No. 2000-342855 can be mentioned. According to the invention, by generating a united character in which the characters operated by the respective players are united,
Two characters operate one character. This allows the player to feel a sense of solidarity by operating one character by two people.

[0004]

However, in the above-mentioned conventional technique, the operations by the two players are independently reflected in the motion of the character. In the invention described in the above publication, two players operate one character, but the operations to be performed by each player are assigned in advance. That is, the united character performs different actions (for example, attacks) according to each player. Thus, in the invention described in the above publication, the operation by one player and the operation by the other player are not linked. Therefore, in the above-mentioned conventional technique, there is no one in which the operations by the two players are interlocked with each other.
I couldn't get enough game feeling of operating two characters.

Therefore, it is an object of the present invention to provide a game device in which the operations of two players are interlocked and reflected in the motion of one character.

May be used.

Next, the operation data generated by the controller 104 will be described. FIG. 3 is a diagram showing a configuration of operation switches of the controller 104 shown in FIG. In FIG. 3, the controller 104 uses the Z button 3
01, R button 302, L button 303, A button 304, B button 305, X button 306, Y
Button 307, start button 308, cross key 3
09, a main analog stick 310, and a sub-analog stick 311. FIG. 4 shows the configuration of the operation data generated by the controller 104 configured as described above.

As shown in FIG. 4, the operation data is, for example, 7
Composed of bytes. The 8th bit of the first byte is the Z button 301, the R button 302, the L button 303, the A button 304, the B button 305, the X button 306, and the Y button.
The operation states of the button 307 and the start button 308 are shown. Specifically, the 8th bit of the 1st byte indicates whether or not each of the above buttons is pressed. The second byte represents the operating state of the cross key 309. First 4 of the 2nd byte
Each bit represents whether or not the up, down, left, and right buttons on the cross key 309 are pressed. The remaining 4 bits of the 2nd byte are not used in this embodiment.

The third byte represents the x-axis data of the main analog stick 310. The x-axis data means the main analog stick 310 in the x-axis direction shown in FIG.
This is data indicating the degree to which is tilted. That is,
The 3rd byte shows how much the main analog stick 310 is tilted in the direction of the x-axis shown in FIG. Therefore, the input value of the main analog stick 310 differs depending on the degree to which the player defeats the stick. The 4th byte is the main analog stick 3.
Represents 10 y-axis data. The y-axis data is data indicating the degree to which the main analog stick 310 is tilted in the y-axis direction shown in FIG. As described above, the angle (degree) and the direction in which the main analog stick 310 is tilted can be represented by the 3rd and 4th bytes of the operation data. The 5th and 6th bytes represent x-axis data and y-axis data for the sub-analog stick 311. Therefore, as in the case of the main analog stick 310, the angle (degree) and the direction in which the sub analog stick 311 is tilted can be represented by the 5th and 6th bytes of the operation data.

The 7th byte represents analog data of the R button 302 and the L button 303. Here, the analog data of the R button 302 (L button 303) is data indicating the degree to which the R button 302 (L button 303) is pressed. Therefore, the value indicated by the 7th byte data changes according to the degree to which the player presses the R button 302 or the L button 303 (for example, the pressing amount of the button). The first 4 bits of the 7th byte is the R button 30.
2 represents the analog data, and the remaining 4 bits represent the analog data of the L button 303. In the above,
Although the controller 104 has been described with reference to FIGS. 3 and 4, the operation data and the operation switch of the controller 105 are the same as those of the controller 104.

Next, an outline of the game played in this embodiment will be described. FIG. 5 is a diagram showing a display example of a game played in this embodiment. In addition, FIG.
FIG. 11 is a diagram showing a character operated by a player in the game shown in FIG. 6A is a view seen from the rear of the cart, and FIG. 6B is a view seen from the side of the cart.
The game in this embodiment is a race game as shown in FIG. 5, and the player operates the character shown in FIG. In this embodiment, the number of players is two,
These are player A and player B, respectively. In addition, FIG.
As shown in FIG. 6, the character operated by the player is a moving body character (cart) 601, a driver character 602 driving the moving body character 601, and a boarding on the moving body character 601 in addition to the driver character 602. The passenger character 603. The mobile character 601, the driver character 602, and the passenger character 603 move integrally. The player A uses the controller 104 to drive the driver character 6
Operate 02. On the other hand, the player B is the controller 1
The passenger character 603 is operated using 05. Here, the driver character 602 and the moving body character 6
The operation on 03 is reflected on the behavior of the mobile character 601 in addition to the behavior of each character. Therefore, the moving body character 601 is operated by the operation of the driver character 602 by the player A and the operation of the passenger character 603 by the player B. The present racing game is a game in which the players A and B drive the cart by performing the above-described operation and race with another cart operated by another player or a game device. In the following description, the characters operated by the players A and B, that is, the moving body character 601 (kart) and the driver character 602.
And a passenger character 603,
It is called an operation target character. In addition, in the present embodiment, the driver character 602 and the passenger character 603 can be switched at a timing desired by the player. Specifically, in the game according to the present embodiment, a plurality of person characters imitating a person, which can be the driver character 602 and the passenger character 603, are prepared in advance, and the character of the controller is set at a desired timing during the race. The character set as the driver character 602 and the character set as the passenger character 603 can be changed according to the operation of the button. In addition, each person character is given a unique attribute (for example, weight, etc.), which makes it difficult for the moving body character 603 to rotate when the person character with a heavy weight is the driver, and when the person character is a passenger. The moving body character 6 so that it can be easily rotated.
The operation of 03 is further changed.

Next, the game processing performed in the game device according to this embodiment will be described. Here, the game device includes the game machine main body 101 and the controller 104 in which the DVD-ROM 102 is mounted.
FIG. 7 shows the CPU 202 and the GPU 20 of the game device.
9 is a flowchart showing a flow of game processing performed by the cooperative operation of No. 4 of FIG. In this embodiment, the CPU 2
Although the game process is performed by the cooperative operation of 02 and the GPU 204, it is also possible to cause almost all the process such as the geometry process to be performed only by the CPU 202, for example.

When the game is started, first, the CPU 20
2 forms a game space (step S101). Specifically, the CPU 202 arranges a terrain object for forming a terrain such as a race course at initial coordinates of a three-dimensional coordinate system (world coordinate system) in the game space. Next, the CPU 202 arranges the operation target character appearing in the game at the initial coordinates of the world coordinate system (step S102). A plurality of operation target characters may appear in the game, for example, when there is an operation target character operated by the game device. With the above processing, preparations for starting the race are made, and step S
After 102, the race begins.

After the start of the race, the CPU 202 obtains the first and second operation data from the controllers 104 and 105, respectively (step S103), and determines whether or not the operation data has been input (step S104). In step S104, "operation data is input"
Indicates that the operation data includes data related to inputs necessary for game operation. Here, in the present embodiment, for the game operation, for example, the Z button of the controller 104 (controller used by the player A), the A button and the main analog stick, and the Z button of the controller B (controller used by the player B), The R and L buttons shall be used. Therefore, when the acquired first and second operation data include data related to these inputs, C
The PU 202 determines that operation data has been input. On the contrary, when the operation data does not include data related to these inputs, the CPU 202 determines that the operation data is not input. For example, when the first operation data acquired in step S103 includes only data related to the input of the sub-analog stick 311, the CPU 202 determines that the operation data has not been input.

If it is determined in step S104 that no operation data has been input, the CPU 202
The processes of steps S105 and S106 are skipped, and the process of step S107 is performed. On the other hand, when it is determined in step S104 that the operation data is input, the CPU 202 performs the character changing process (step S105). The character change process is a process relating to a change in the positional relationship and role of the driver character 602 and the passenger character 603 shown in FIG. The details of the character change process are described in FIG. After step S105, CP
U202 performs a character action determination process (step S106). The character motion determining process is a process of determining the motions of the driver character 602, the passenger character 603, and the moving body character 601. The details of the character action determination process have been described with reference to FIG.

Next, the CPU 202 issues a coordinate conversion command to the GPU 204, and accordingly the GPU 204
Converts a character, a terrain object, or the like from the world coordinate system to a camera coordinate system (also referred to as a viewpoint coordinate system) based on a virtual camera (step S10).
7). Here, the virtual camera is a viewpoint when the game space is displayed on the screen. Next, the GPU 204 further converts the camera coordinate system converted in step S107 into a two-dimensional projection plane coordinate system (also referred to as screen coordinate system) (step S108). During the conversion process to the projection plane coordinate system, the GPU 204 performs clipping, texture designation, lighting processing, and the like, and stores depth information from the viewpoint in the Z buffer. And GPU204
Is a raster process, that is, a process for writing (drawing) color information (color data) based on the texture for each polygon projected in the projection plane coordinate system into the color buffer 216 while referring to the Z buffer 217.
A game image is generated (step S109), and the game image is displayed on the television 105 (step S11).
0). One game image is generated and displayed by the processing in steps S103 to S110 described above.

After step S110, the CPU 202
Determines whether to end the game (step S1)
11). For example, when the race ends or the player performs a predetermined game end operation, the CPU 202 determines to end the game. When it is determined to end the game, the CPU 202 ends the processing shown in FIG. On the other hand, if it is not determined to end the game,
The CPU 202 has steps S103 to S111.
Repeat a series of processing of.

Next, the character changing process in step S105 will be described. First, the outline of the character change processing will be described. As described above, the character changing process is a process relating to the positional relationship and the role change of the driver character 602 and the passenger character 603 shown in FIG. Specifically, in the character change processing,
The CPU 202 changes the positional relationship and roles of the driver character 602 and the passenger character 603 when the player inputs a character change operation. In this embodiment, the change process is performed by the controller 1
It shall be started by pressing the Z buttons of 04 and 105. Controllers 104 and 10
When the Z button of No. 5 is pressed, the CPU 202 displays an animation for changing the driver character 602 and the passenger character 603 (in other words, reproducing motion data of the driver character and the passenger character).

FIG. 8 is a diagram showing an example of animation in the character changing process shown in step S105 of FIG. As shown in FIG. 8, the CPU 202 causes the driver character 602 (character B in FIG. 8) to move to the rear part of the vehicle and the passenger character 603 (character A in FIG. 8) to move to the front part of the vehicle. , Display multiple game images. This display is performed by repeating the processing related to the loop from step S103 to step S111 shown in FIG. 7 a plurality of times. Referring to FIG. 8 as an example, in step S110 of FIG.
By sequentially displaying the images shown in (e) to (e), an animation for changing the driver character 602 and the passenger character 603 is displayed. The character changing process in step S105 is a process for performing such display. The details of the character change process will be described below.

FIG. 9 is a flowchart showing details of step S105 shown in FIG. First, the CPU 202
Determines whether the replacement process flag is ON (step S201). Here, the replacement processing flag means CP
This is a flag indicating whether or not U202 is in the process of performing the character changing process. That is, the replacement processing flag is ON
Means that the CPU 202 is in the process of performing the character changing process. On the contrary, the fact that the substitution process flag is OFF indicates that the CPU 202 is not performing the character substitution process. Step S201
If the replacement process flag is ON, the CPU 2
02 performs the process of step S204, and then step S2
The processing of 02 is skipped. Therefore, during the character changing process, the CPU 202 does not perform the process using the operation data acquired in step S103. That is, the operation input from the player is ignored during the character changing process.

On the other hand, when the alternation process flag is OFF in step S201, the CPU 202 turns on the input of the Z button of the controllers 104 and 105 based on the operation data acquired in step S103.
It is determined whether or not (step S202). The determination in step S202 is performed by referring to the first bit of the first byte in the first and second operation data acquired in step S103 (see FIG. 4). In the determination of step S202, when the input of the Z button is ON, the CPU 202 sets the replacement process flag to ON (step S203), and step S203.
The process of 204 is performed. On the other hand, the input of the Z button is OF
If the result is F, the CPU 202 ends the character changing process in step S105.

If the replacement process flag is ON in step S201, or if the replacement process flag is set ON in step S203, the CPU 202
Performs layout conversion processing (step S204). The arrangement conversion processing is processing for changing the arrangement of the driver character 602 and the passenger character 603, as in the display example shown in FIG. That is, in step S204, the CPU 202 gradually changes the arrangement coordinates and postures of the driver character 602 and the passenger character 603 so as to alternate between them. Explaining FIG. 8 as an example, the immediately preceding loop (step S103 to step S1)
11), the driver character 602 and the passenger character 603 are shown in FIG.
In the case of the state shown in FIG. 8B, the action of each character is decided in the state shown in FIG. 8C. As described above, the character change processing is performed by repeating the processing related to the loop from step S103 to step S111 shown in FIG. 7 a plurality of times. That is, the process of changing the driver character 602 and the passenger character 603 does not replace each character in one placement conversion process, but is completed by performing the placement conversion process a plurality of times.

Next, the CPU 202 determines whether or not the character change is completed (step S205). The determination in step S205 is made in step S2 performed immediately before.
This is performed based on the contents of the layout conversion process 04. Referring to FIG. 8 as an example, when the driver character 602 and the passenger character 603 are in the state shown in FIG.
02 determines that the character change is completed. On the contrary, if the characters are not in the state shown in FIG. 8E in the arrangement conversion process performed immediately before, the CPU 2
02 determines that the character change has not been completed.

If it is determined in step S205 that the character replacement has not been completed, the character replacement process of step S105 ends. In this case, since the alternation process flag remains set to ON, the arrangement conversion process of step S204 is performed again in the next loop (loop from step S103 to step S111). On the other hand, in the determination of step S205,
When the character change is completed, the CPU 202 changes the character data of the driver character 602 and the passenger character 603 (step S206). The character data is an attribute unique to the character described above, and in the present embodiment, is character weight data. That is, in step S206, the CP
U202 is the weight data of the driver character 602,
The weight data of the passenger character 603 is changed.

Next, the CPU 202 changes the role of the player (step S207). That is, when the player A is operating the driver character and the player B is operating the passenger character, the player A is operating as the passenger character.
The setting is changed so that the player B operates each driver character. Specifically, the controller 104
The setting related to the first operation data acquired from the controller and the second operation data acquired from the controller 105 is changed. As a result, the object operated by the first operation data (driver character) and the object operated by the second operation data (passenger character) are reversed. Finally, the CPU 202 sets the replacement processing flag to OF.
It is set to F (step S208), and the character changing process is ended.

In the present embodiment, the process of changing the driver character 602 and the passenger character 603 is performed by pressing the Z button of the controller 104 and the controller 105. here,
In another embodiment, the process of changing the driver character 602 and the passenger character 603 may be performed by pressing the Z button of either the controller 104 or the controller 105.

Next, the character motion determination process of step S106 will be described. First, the outline of the character motion determination process will be described. The character motion determination process is a process of determining the motions of the driver character 602, the passenger character 603, and the moving body character 601 based on the first and second operation data from the controllers 104 and 105. Hereinafter, the motion of each character and the controller 10 will be described with reference to FIGS. 10 to 12.
The relationship with operations 4 and 105 will be described. As described above, here, the player A operates the driver character 602 using the controller 104,
It is assumed that the player B uses the controller 105 to operate the passenger character 603.

The driver character 602 is operated by the main analog stick of the controller 104. Specifically, when the player A tilts the main analog stick of the controller 104, the driver character 602 operates the steering wheel. The operation of the main analog stick is performed by the moving character 60.
It is also related to the action (1) (1).

FIG. 10 shows a case where the main analog stick of the controller 104 is tilted to the right.
It is a figure which shows the display state of each character shown in FIG. It should be noted that FIG. 10A is a view seen from the rear of the cart.
0 (b) is a view seen from the side of the cart. Figure 10 (b)
When the main analog stick of the controller 104 is tilted to the right as shown in FIG.
For 2, turn the handle to the right and turn the neck to the right. In this case, the mobile character 601 turns its front wheel to the right and changes its traveling direction to the right.

The passenger character 603 is operated by the R button and the L button of the controller 105.
Specifically, when the player B presses the R button of the controller 105, the passenger character 603 performs a motion of applying a load to the right side of the moving body character 601.
In addition, when the player B presses the L button,
The passenger character 603 performs a motion of applying a load to the left side of the cart. The operation of the R button and the L button is also related to the motion of the moving body character 601.

FIG. 11 is a diagram showing a display state of each character shown in FIG. 6 when the R button of the controller 105 is pressed. As shown in FIG. 8, when the R button of the controller 105 is pressed, the passenger character 603 operates so as to put weight on the right side of the moving body character 601. In this case, the moving body character 601 tilts its posture to the right by a predetermined angle (Δα1 in FIG. 11) and changes the traveling direction to the right. In the present embodiment, the action of the passenger character 603 is determined only based on whether the R button or the L button is pressed. Here, in another embodiment, the weight application method (posture) of the passenger character 603 may be changed according to the degree of depression of the R button or the L button.

Next, the operation of the mobile character 601 will be described. The traveling direction of the mobile character 601 is determined by the main analog stick of the controller 104 and the R and L buttons of the controller 105, and the moving speed is determined by the A button of the controller 104. Therefore, the moving body character 60
No. 1 movement direction and driver character 602
And the motion of the passenger character 603 is interlocked. In other words, the motion of the mobile character 601 changes depending on the motions of the driver character 602 and the passenger character 603. FIG. 12 shows the controller 104.
Main analog stick and controller 105
FIG. 7 is a diagram showing a traveling direction of the moving body character 601 shown in FIG. 6 when the R button is operated. The details of the operation of the mobile character 601 will be described below.

First, as shown in FIG. 12A, when only the main analog stick of the controller 104 is tilted to the right by a predetermined angle, the direction of the moving body character 601 is changed to the right by Δβ1. FIG. 12A shows the same case as that shown in FIG. Further, as shown in FIG. 12B, when only the R button of the controller 105 is pressed, the direction of the moving body character 601 changes to the right by Δα2. Note that FIG. 12B shows the same case as that shown in FIG. 11. Therefore, although not shown in FIG. 12B, the moving body character 601 is tilted by Δα1 in the rotation direction about the traveling direction as shown in FIG. 11.

Next, as shown in FIG. 12C, the main analog stick of the controller 104 is set at a predetermined angle (see FIG.
When tilted to the right by the same angle as in the case of 2 (a) and the R button of the controller 105 is pressed, the direction of the moving body character 601 changes to the right by Δγ1. In this case, the driver character 602 is operated so as to turn the steering wheel to the right, and the passenger character 603 is operated so as to perform a loading operation to the right side of the moving body character 601. Where Δγ1
Is larger than the sum of Δβ1 and Δα2. Therefore, when the moving body character 601 is operated to turn to the right for both the driver character 602 and the passenger character 603, it turns to the right more than when either one of them is operated. In other words, the moving body character 601 is easily turned to the right.

Further, as shown in FIG. 12D, the main analog stick of the controller 104 has a predetermined angle (see FIG. 1).
When tilted to the right by the same angle as in the case of 2 (a) and the L button of the controller 105 is pressed, the direction of the moving body character 601 changes to the right by Δγ2. In this case, the driver character 602 is operated so as to turn the steering wheel to the right, and the passenger character 603 is operated so as to perform a load operation to the left side of the moving body character 601. Where Δγ2
Is smaller than Δβ1. Therefore, the driver character 6
02, the moving body character 601 is operated to turn to the right, and the passenger character 603 is operated to turn to the left. When the moving body character 601 is operated to turn to the left, the right side is larger than when only the driver character 602 is operated. The bending angle becomes smaller. In other words, it makes the moving character 601 difficult to turn right. As described above, the motion of the moving body character 601 is determined by reflecting the operation on the passenger character 603 in addition to the operation on the driver character 602.

The details of the character action determination process in step S106 will be described below. FIG. 13 is a flowchart showing details of step S106 shown in FIG. First, the CPU 202 determines whether or not the alternation process flag is ON (step S301). When the substitution process flag is ON, the CPU 202 ends the character motion determination process. Therefore, during the character changing process, the CPU 202 does not perform the process using the operation data acquired in step S103. That is, the operation input from the player is ignored during the character changing process. On the other hand, if the replacement process flag is OFF, the CPU 202 performs the first operation control process (step S302). The first motion control process is a process of controlling the motion of the driver character 602. In the first motion control process, the motion of the driver character 602 is determined based on the operation applied to the main analog stick included in the controller 104. The details of the first operation control process will be described below.

FIG. 14 shows the step S302 shown in FIG.
3 is a flowchart showing the details of FIG. First, the CPU 20
2 determines whether or not the driver character 602 is operated (step S401). The determination in step S401 is performed depending on whether or not the first operation data acquired in step S103 includes data for operating the driver character 602.
That is, the area related to the main analog stick in the first operation data (3rd byte and 4th byte)
If the information includes information indicating that the main analog stick is tilted, the CPU 202 determines that the driver character 602 is being operated. On the contrary, when the data of the area related to the main analog stick in the first operation data indicates that the main analog stick is not tilted, the CPU 202 determines that the driver character 602 is not operated. When it is determined in step S401 that the driver character 602 is not operated, the CPU 202 determines in step S3.
The first operation control process 02 is ended. On the other hand, when it is determined in step S401 that the driver character 602 is being operated, the CPU 202 determines in step S103.
An operation command for the driver character 602 is extracted from the first operation data acquired in step S40 (step S40).
2). That is, the CPU 202 extracts the data of the third byte and the data of the fourth byte from the operation data. Further, the CPU 202 determines the motion of the driver character 602 based on the extracted operation command (step S40).
3), the first operation control process of step S302 ends. The action determined in step S403 is determined, for example, such that the driver character 602 turns the steering wheel and turns his / her neck by an amount corresponding to the tilt angle of the main analog stick in the x-axis direction.

Returning to the description of FIG. 13, after the first operation control processing, the CPU 202 executes the second operation control processing (step S303). The second motion control process is a process of controlling the motions of the passenger character 603 and the moving body character 601. In the second motion control process, the motion of the passenger character 603 is determined based on the operation applied to the R button and the L button included in the controller 105. Further, in the second motion control process, the motion of the moving body character 601 is determined by reflecting the motion of the passenger character 603. That is, the controller 1
The motion of the moving body character 601 is determined based on the operation performed on the R button and the L button of the controller 105 in addition to the main analog stick 04 and the A button. The details of the second operation control process will be described below.

FIG. 15 shows step S303 shown in FIG.
3 is a flowchart showing the details of FIG. First, the CPU 20
2 performs the action determination process regarding the passenger character 603 (step S501). The action determination process for the passenger character 603 is based on the operation added to the R button and the L button included in the controller 105.
This is processing for determining the motion of the passenger character 603.
Hereinafter, the passenger character 603 shown in step S501
The details of the operation determination process regarding will be described.

FIG. 16 shows the step S501 shown in FIG.
3 is a flowchart showing the details of FIG. First, the CPU 20
2 determines whether or not the passenger character 603 is operated (step S601). The determination in step S601 is performed depending on whether or not the second operation data acquired in step S103 includes data for operating the passenger character 603.
That is, the R button and L in the second operation data
If the area related to the button includes information indicating that the R button or the L button is pressed, the CPU
202 determines that the passenger character 603 is being operated. On the contrary, the data in the area related to the R button and the L button in the second operation data is the R button or the L button.
If the button is not pressed, the CPU 20
2 determines that the passenger character 603 is not operated. In the present embodiment, as the area related to the R button and the L button in the second operation data,
The second and third bits of the first byte are used, and the analog data of the seventh byte is not used.

If it is determined in step S601 that the passenger character 603 is not operated, the CPU 20
2 ends the second operation control process of step S501. On the other hand, when the passenger character 603 is operated in the determination of step S601, the CPU 202
Extracts an operation operation command for the passenger character 603 from the second operation data acquired in step S103 (step S602). That is, the CPU 202
Extracts the data of the second and third bits of the first byte from the second operation data. Furthermore, CPU
The 202 determines the motion of the passenger character 603 based on the extracted operation command (step S603), and ends the motion control process of the passenger character 603 of step S501. In step S603, the motion of the passenger character 603 is such that a load is applied to the right side of the moving body character 601 when the R button is pressed and a load is applied to the left side of the moving body character 601 when the L button is pressed. Is decided.

Returning to the explanation of FIG. 15, the passenger character 6
After the action determination process for 03, the CPU 202 performs the action determination process for the moving character 601 (step S502). The action determination process regarding the moving body character 601 is performed by the R
This is a process of determining the action of the moving body character 601 based on the operation applied to the button and the L button. Hereinafter, the details of the action determination process regarding the moving body character 601 shown in step S502 will be described.

FIG. 17 shows the step S502 shown in FIG.
3 is a flowchart showing the details of FIG. First, the CPU 20
2 determines whether or not the driver character 602 is being operated, that is, whether or not an operation related to the driver character 602 turning the steering wheel is being performed (step S701). The determination in step S701 is similar to the determination in step S401 shown in FIG. When the determination in step S701 is affirmative, the CPU 202 determines whether or not the passenger character 603 is operated, that is, whether or not the operation related to the action of the passenger character 603 applying a load is performed (step S7).
02). The determination in step S702 is similar to the determination in step S601 shown in FIG. When the determination in step S702 is negative, that is, the driver character 602
When no operation is performed on both the passenger character 603 and the passenger character 603, the CPU 202 determines that the moving body character 6
The posture of 01 is maintained as it is (step S70).
3).

Step S701 or step S702
In either case, if the determination result is affirmative, C
PU202 changes a posture according to operation (step S704). Specifically, the CPU 202 extracts data regarding the main analog stick, the R button, and the L button of the controller 104 from the first and second operation data acquired in step S103,
The posture of the mobile character 601 is determined based on the extracted data. The method of determining the posture of the moving body character 601 has been described in the above description of FIG.

After step S704, the CPU 202
Changes the posture further according to the attribute of the character (step S705). As described above, in the present embodiment, a plurality of person characters that can be the driver character 602 and the passenger character 603 are prepared in advance, and each person character has its own unique attribute (weight in the present embodiment. )have. In the process of step S705, the CPU 202 determines the moving body character 60 based on the weight attribute unique to each person character.
Change the posture of 1. For example, the CPU 202
Is a moving body character 601 (moving body character 60
1) Based on the weight difference between the driver character 602 riding in the front and the passenger character 603 riding in the rear, the bending state of the moving body character 601 by the load operation of the passenger character 603 is changed. Specifically, in FIG. 12, the weight difference shown in FIG.
The values of Δγ1 shown in (c) and Δγ2 shown in FIG. For example, when the weight of the driver character 602 is heavy and the weight of the passenger character 603 is light, the moving body character 6 due to the load operation of the passenger character 603.
The bend degree of 01 is made small. That is, Δγ1 and Δ
The difference between β1 and the difference between Δγ2 and Δβ1 are reduced. On the contrary, when the weight of the driver character 602 is light and the weight of the passenger character 603 is desired, Δγ1 and Δβ1
And the difference between Δγ2 and Δβ1 are increased.
The posture of the moving body character 601 is determined by the above-described processing of steps S701 to S705.

After determining the posture of the mobile character 601, that is, after step S703 or step S705, the CPU 202 determines whether or not the accelerator operation of the mobile character 601 is performed (step S7).
06). The determination in step S706 is step S
This is performed depending on whether or not the first operation data acquired in 103 includes data for operating the accelerator of the mobile character 601. That is, when the area (the 4th bit of the 1st byte) related to the A button in the first operation data includes information indicating that the A button is pressed, the CPU 202 performs the accelerator operation. Determine that On the other hand, when the data of the area related to the A button in the operation data indicates that the A button is not pressed, the CPU 202 determines that the accelerator operation is not performed.

If the determination in step S706 is negative, C
The PU 202 performs the process of step S710. on the other hand,
If the determination in step S706 is affirmative, the CPU 202
Determines the acceleration in the posture direction (step S70).
7). The acceleration in the posture direction is expressed by a vector, and the direction of the vector is calculated in steps S701 to S70.
5 is determined by the posture of the moving body character 601. For the acceleration in the posture direction, see Fig. 1.
8 are described. Further, the CPU 202
It is determined whether or not the passenger character 603 has performed an operation related to the action of applying a load (step S70).
8). The determination in step S708 is made in step S7.
It is similar to the determination of 02. If the determination in step S708 is negative, the CPU 202 performs the process of step S710. On the other hand, if the determination in step S708 is affirmative, C
The PU 202 sets the acceleration due to the load (step S709). In the present embodiment, the acceleration due to the load is represented by a vector having a predetermined angle with respect to the traveling direction of the moving body character 601. Note that the acceleration due to the load has been described in FIG.

Step 706, S708 or S709
After that, the CPU 202 calculates the speed of the mobile character 601 (step S713). FIG. 18 is a diagram for explaining the method of calculating the velocity of the moving body character in step S713 of FIG. As shown in FIG. 18, in the calculation in step S713, the vector 7 indicating the current speed is used.
01, a vector 702 indicating the acceleration in the posture direction, and a vector 703 indicating the acceleration due to the load, a vector 704 indicating the velocity of the moving body character is calculated. Here, the vector 701 indicating the current speed is determined based on the speed of the moving body character 601 calculated in step S713 in the previous loop (loop from steps S103 to S110). Further, as described above, the vector 702 indicating the acceleration in the posture direction is calculated in step S707, and the direction is based on the operation by the main analog stick of the controller 104 and the R and L buttons of the controller 105. It is determined. The size of the vector 702 is determined by pressing the A button (for example, the pressing time). The vector 703 indicating the acceleration due to the load is calculated in step S709, and the direction thereof is a direction that is oriented at a predetermined angle with respect to the traveling direction of the moving body character 601. The size of the vector 703 is a predetermined size that is set in advance. Note that in other embodiments, the R button or L
Depending on how much the button is pushed, the passenger character 603
If the weight application method (posture) changes, vector 70
The size of 2 changes depending on how much the R button or the L button is pressed. The velocity of the mobile character 601 is calculated as 0 when the acceleration in the posture direction and the acceleration due to the load are not calculated. For example, in FIG. 18, when there is no acceleration due to the load,
That is, when the load operation of the passenger character 603 is not performed, the speed of the moving body character 601 is shown as a vector 705 that is the sum of the vector 701 indicating the current speed and the vector 702 indicating the acceleration in the posture direction. .

Next, the CPU 202 executes step S710.
Based on the speed calculated in step 6, the moving body character 6
The position of 01 is updated (step S711), and the action determining process of the moving body character 601 of step S502 is completed. As described above, the posture and position of the moving body character 601 to be displayed are determined. It should be noted that the positions of the driver character 602 and the passenger character 603 are determined so as to get on the moving body character 601.

As described above, according to this embodiment, the players A and B can operate the mobile character 601 in cooperation with each other. Furthermore, players A and B
Can operate two characters, a driver character 602 and a passenger character 603, respectively. As described above, according to the present embodiment, the player operates different characters,
A new game feeling of operating one character in cooperation with another player can be obtained.

In this embodiment, the three characters, that is, the moving body character 601, the driver character 602, and the passenger character 603 are the objects to be operated by the player. Here, the operation target of the player is
The number does not necessarily have to be three, and may be at least two characters. For example, the target operated by the player A may be a mobile character, and the target operated by the player B may be a passenger character.

Further, in the present embodiment, each character is a person or a cart. Here, in another embodiment, one character may be composed of a plurality of persons and a moving body (cart). For example, the passenger character may be composed of two persons, and a total of three persons including the driver character may be on the cart operated by the player.

In this embodiment, the character changing process is performed in step S105 shown in FIG. In the character change processing, the player can change the behavior of the moving body character by changing the driver character 602 and the passenger character 603 even when the same operation is performed. For example, when the character A is the driver character 602 and the character B is the passenger character 603, and vice versa, the bending degree of the moving body character 601 is different. This is expected to further increase the fun of the game. In addition, in the present embodiment, the attribute of the character is weight, but it may be a physical attribute such as height, or may be an attribute completely unrelated to the physical shape.
