[0001]
BACKGROUND OF THE INVENTION
The present invention program The program The present invention relates to an information storage medium storing game information and a game device.
[0002]
[Prior art]
Conventionally, in a racing game such as a car or a motorcycle, in order to rescue a beginner player who is not so familiar with the game or to produce a close battle, for each enemy vehicle, the distance and position between the vehicle and the vehicle Depending on the relationship, the traveling speed of the enemy vehicle is adjusted.
Specifically, when the host vehicle is located behind the target enemy vehicle, the traveling speed of the enemy vehicle is reduced, while the host vehicle is positioned ahead of the target enemy vehicle. To increase the running speed of that enemy vehicle. At this time, as the distance between the host vehicle and the enemy vehicle increases, the adjustment amount (increase or decrease) of the traveling speed is increased. On the contrary, if the distance is small, the adjustment amount is decreased. .
[0003]
As a result, for example, when the host vehicle is traveling far behind the target enemy vehicle, the host vehicle can easily catch up with the enemy vehicle by greatly reducing (decelerating) the traveling speed of the enemy vehicle. Become. In addition, when the host vehicle and the target enemy vehicle are running close together, the amount of adjustment of the traveling speed of the enemy vehicle is reduced, and the distance between the two vehicles is maintained without being attached. Can produce.
[0004]
[Problems to be solved by the invention]
However, in this conventional method, for each enemy vehicle, the running speed is adjusted according to the distance from the own vehicle and the positional relationship, so as the race time elapses, The enemy cars are concentrated, that is, the difference between the first car and the last car in the entire vehicle group is reduced.
[0005]
This will cause a discrepancy with the actual race development, such as the difference in the distance between the fastest and slowest cars increasing with time, giving the player unnaturalness. I was sorry.
Further, when the virtual camera follows the own vehicle, there are problems that enemy vehicles are densely packed around the own vehicle, so that the number of vehicles entering the field of view increases and the drawing processing load increases.
[0006]
An object of the present invention is to prevent an unnatural game development such that enemy cars are densely packed around the host vehicle and the difference between the head and the tail is reduced as the race progresses.
[0007]
[Means for Solving the Problems]
To solve the above problems The first of According to the present invention, a player character (for example, the host vehicle 20a in FIG. 1) and a plurality of computer-controlled characters (for example, the enemy vehicle 20b in FIG. 1) are given to a device by a calculation / control of a processor. Game information for executing a game that moves toward a point (for example, a game that moves in the same direction on a predetermined course, such as a motorcycle racing game in the embodiment), of the plurality of computer controlled characters The positional relationship between the first specifying means for specifying any one character (for example, the leading enemy vehicle specifying unit 411 in FIG. 5), the character specified by the first specifying means, and the player character Based on the first speed changing means for uniformly changing the moving speed of the plurality of computer controlled characters (for example, the speed adjustment function shown in FIG. 5). Comprising part 413, and and the speed adjustment unit 414), the information for the function to the device Game information .
[0008]

A game device (for example, the game device 100 of FIG. 5), a specifying means (for example, a leading enemy vehicle specifying unit 411 of FIG. 5) for specifying any one of the plurality of computer controlled characters; Based on the positional relationship between the character specified by the specifying means and the player character, speed changing means for uniformly changing the moving speeds of the plurality of computer controlled characters (for example, the speed adjustment calculation unit 413 in FIG. 5). And a speed adjustment unit 414) Game device .
[0009]
this First 1 or First 11 of According to the invention, it is possible to uniformly change the moving speeds of the plurality of computer-controlled characters in accordance with the positional relationship between the specified character and the player character. In other words, a plurality of computer-controlled characters are treated as a group of characters represented by the specified characters, and it is possible to adjust the speed while maintaining the dispersion of these character positions. Become.
[0010]
Therefore, the computer-controlled characters do not get crowded around the player character as time passes. For this reason, for example, in a racing game in which the character is a car, a motorcycle, etc., the actual race development in which the difference between the fastest leading car and the slowest trailing car shrinks as the race time elapses. It is possible to adjust the speed without causing any contradiction.
[0011]
Here, the positional relationship means, for example, the direction of the front, back, left and right (further up and down), the distance between the two, and the like.
[0012]
That is, for example 4th Invention As , Mentioned above Assuming that the game information includes information for specifying the most leading character among the plurality of computer controlled characters, the first identifying means includes: Based on the positional relationship with the player character, speed adjustment for a plurality of computer-controlled characters can be performed.

For example, when the number of characters located within a predetermined distance from the player character exceeds a predetermined number, By adjusting the speed, the player character can escape from a group of characters that are densely arranged around the player character.
Furthermore, when the virtual camera follows the player character, the number of characters to be drawn when the game image is generated can be reduced by setting the predetermined distance as the visual field of the virtual camera. An increase in processing load related to drawing can be prevented.
[0020]

[0021]
Here, the conditions for instructing the change include, for example, the play level of the player, the relative distance between the player character and the identified character, the elapsed time of the game, the moving distance of the character, and the like.
[0022]
So this 8th According to this invention, for example, speed adjustment is performed only when the level of the player is a beginner level, and it becomes possible to easily catch up with a player character that tends to be late to other characters (a plurality of computer-controlled characters).
In addition, when the player character temporarily leaves another character (computer control character) due to some accident during the game, it is possible to easily catch up again.
Further, when the game is a game that circulates a predetermined course, by adjusting the speed only in the final lap, it is possible to produce a reversal of the final stage of the race, a more heated close battle, or the like.
[0023]
Also, 9th Invention As , First ~ 8th Either Invention And the first speed changing means has a positional relationship between any one of the plurality of player characters and the character specified by the first specifying means.

[0030]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In the following, a motorcycle racing game will be described as an example, but the application of the present invention is not limited to this.
[0031]
First, the principle will be described.
FIG. 1 is a diagram illustrating an example of a race course 10 arranged in a game space.
As shown in the figure, on a race course 10, characters (hereinafter simply referred to as “bikes”) 20 simulating a plurality of (eight) motorcycles are arranged. Then, the motorcycle racing game proceeds when these motorcycles 20 are instructed and controlled by a player or a computer. That is, these motorcycles 20 start traveling in the same direction and at the same time from the start point (shown as “START” in the figure) 11 and compete for their traveling order.
In FIG. 1, eight motorcycles 20 are shown. Of course, any number of motorcycles 20 may be used.
[0032]
Among these motorcycles 20, the motorcycle 20 a is a player character (hereinafter referred to as “own vehicle”) to be operated by the player, and its speed, traveling direction, and the like are controlled by an operation instruction from the player.
[0033]
In addition, the remaining seven motorcycles (hereinafter referred to as “enemy vehicles”) 20b excluding the host vehicle 20a are determined by computer control in terms of speed, traveling direction, and the like according to the set performance. Of these seven enemy vehicles 20b, the enemy vehicle that runs the most is called the “first enemy vehicle”, and will be described below using reference numeral 20c. The leading enemy vehicle 20c changes at any time due to the change of the rank accompanying the progress of the race.
[0034]
In this embodiment, the speed of the enemy vehicle 20b is uniformly adjusted (increased or decreased) by the same amount according to the distance (relative distance) between the host vehicle 20a and the leading enemy vehicle 20c. Will be.
[0035]
Next, the expression of the position of the motorcycle 20 on the race course 10 will be described.
FIG. 2 is a diagram showing the position of the motorcycle 20 on the race course 10.
According to the figure, the coordinate value of the position P of the motorcycle 20 is expressed as (d, w). However, d is a distance from the start point 11 along the center line 12 of the race course 10, and w is a distance from the center line 12 of the race course 10.
Here, the position P of the motorcycle 20 means the position of the representative point of the motorcycle 20.
[0036]
Next, the relative distance between the host vehicle 20a and the top enemy vehicle 20c will be described.
FIG. 3 is a diagram showing the relative distance between the host vehicle 20a and the leading enemy vehicle 20c.
As shown in the figure, the coordinate value of the position P of the host vehicle 20a is (dm, wm), and the coordinate value of the position Pt of the leading enemy vehicle 20c is (dt, wt). The relative distance D between the host vehicle 20a and the top enemy vehicle 20c is given by the following equation.
D = dm−dt (1)
According to Formula (1), for example, when the host vehicle 20a is traveling (leading) ahead of the leading enemy vehicle 20c, D> 0, and conversely, the leading enemy vehicle 20c precedes the host vehicle 20a. In such a case, D <0.
[0037]
Next, adjustment of the traveling speed of the enemy vehicle will be described.
In the following, an arbitrary enemy vehicle 20b among a plurality (seven) enemy vehicles 20b will be described, but the same applies to other enemy vehicles 20b. The “speed before adjustment” means a speed obtained based on the position of the motorcycle 20b one frame before, the performance set for the motorcycle 20b, and the like.
[0038]
If the traveling speed before adjustment of the enemy vehicle is v, the adjusted traveling speed v ′ is given by the following equation.
v ′ = v + Δv (2)
According to Equation (2), the adjusted speed v ′ is a value obtained by adding the speed adjustment Δv to the speed v before the adjustment.
[0039]
The speed adjustment Δv is given by the following equation.
Δv = f (D) (3)
According to the equation (3), the speed adjustment Δv is expressed by a function f with the relative distance D between the host vehicle 20a and the leading enemy vehicle 20c as a parameter.
The function f may be any function, but it is desirable that the following condition is satisfied in order to adjust the traveling speed more strongly as the difference between the host vehicle 20a and the enemy vehicle increases. That is, when the host vehicle 20a precedes the host vehicle 20c, a positive value is obtained. On the other hand, when the host enemy vehicle 20c precedes the host vehicle 20a, a negative value is obtained, and the relative distance D is This is a function of increasing the speed adjustment Δv as it increases.
[0040]
Therefore, the function f shown in FIG. 4 is adopted as the function f.
FIG. 4 is a diagram illustrating an example of a relational expression between the relative distance D and the speed adjustment amount Δv.
According to the figure, Expression (3) becomes the following expression.
f (D) = a × D (4)
However, a is a constant and a> 0.
According to Equation (4), the speed adjustment Δv is a value obtained by multiplying the relative distance D between the host vehicle 20a and the leading enemy vehicle 20c by the coefficient a, that is, a value proportional to the relative distance D.
[0041]
That is, when the host vehicle 20a precedes the leading enemy vehicle 20c (D> 0), the relative distance D increases, that is, as the difference between the own vehicle 20a and the leading enemy vehicle 20c increases, the traveling speed of the enemy vehicle. Will increase. On the other hand, when the leading enemy vehicle 20c precedes the own vehicle 20a (D <0), the relative distance D decreases (increases in the negative direction), that is, as the difference between the own vehicle 20a and the leading enemy vehicle 20c increases. The driving speed of enemy vehicles will be reduced.
[0042]
Thus, the speed of the enemy vehicle is adjusted according to the relative distance D between the host vehicle 20a and the leading enemy vehicle 20c.
Similarly, for other enemy vehicles, the speed is adjusted by applying Expression (4). Of course, the enemy vehicle 20b to be applied here includes the top enemy vehicle 20c.
That is, assuming that the speeds v before adjustment of the seven enemy vehicles 20b are v1 to v7, respectively, the adjusted speeds v′1 to v′7 are as follows.
v′n = vn + Δv (5)
However, n = 1-7.
[0043]
As described above, by handling a plurality of enemy vehicles 20b as one vehicle group and adjusting the speed of this vehicle group, the host vehicle 20a can easily catch up with the leading enemy vehicle 20c or can be easily caught up. While achieving the original purpose of doing, it is possible to avoid problems that are contrary to actual race development, such as the difference between the first motorcycle 20 and the last motorcycle 20 being reduced with the passage of time.
[0044]
Furthermore, the degree of dispersion of a plurality of enemy vehicles remains maintained, that is, the enemy vehicles do not particularly concentrate around the own vehicle 20a. For example, the game image viewed from the virtual camera following the own vehicle 20a It is possible to prevent an increase in processing load related to drawing, particularly drawing of enemy vehicles.
[0045]
Next, the configuration of the game apparatus 100 to which the present invention is applied will be described.

Then, a speed adjustment process (see FIG. 9) according to the speed adjustment program 550 is executed to adjust the speed of the enemy vehicle 20b, and the rank table 510, the position table 520, and the speed table 530 are updated.
[0051]
Further, the game calculation unit 410 includes a leading enemy vehicle specifying unit 411, a relative distance calculation unit 412, a speed adjustment calculation unit 413, a speed adjustment unit 414, and a position calculation unit 415.
[0052]
The leading enemy vehicle identifying unit 411 refers to the ranking table 510 and identifies the leading enemy vehicle. Specifically, in the ranking table 510, when the first motorcycle is the own vehicle 20a, the second enemy vehicle 20b is used. In other cases, that is, when the own vehicle 20a is second or lower. The first enemy vehicle 20b is designated as the top enemy vehicle 20c.
[0053]
The relative distance calculation unit 412 refers to the position table 520 and obtains the relative distance D between the leading enemy vehicle 20c identified by the leading enemy vehicle identifying unit 411 and the host vehicle 20a. Specifically, as described in FIG. 3, the relative distance D is the difference between the position coordinate value d of the host vehicle 20a and the leading enemy vehicle 20c according to the equation (1).
[0054]
The speed adjustment calculation unit 413 obtains the speed adjustment Δv from the relative distance D calculated by the relative distance calculation unit 412 according to the speed adjustment calculation formula 540.
[0055]
The speed adjustment unit 414 refers to the speed table 530 and adds the current speed v and the speed adjustment amount Δv calculated by the speed adjustment amount calculation unit 413 for each enemy vehicle 20b.

[0059]
FIG. 6 is a diagram illustrating an example of the order table 510. The ranking table 510 stores the current ranking of the motorcycle 20.
Based on the ranking table 510, the leading enemy vehicle identifying unit 411 identifies the leading enemy vehicle 20c. Specifically, if the first-ranked motorcycle is the own vehicle 20a, the second-ranked motorcycle 20 (the enemy vehicle 20b) should be ranked second or lower (2nd to 8th). For example, the first-ranked motorcycle (the enemy vehicle 20b) becomes the top enemy vehicle 20c. That is, in FIG. 6, the first motorcycle is the “enemy vehicle A” because the first-ranked motorcycle is the “enemy vehicle A”.
The content is updated by the game calculation unit 410 in accordance with the update of the position table 520.
[0060]
FIG. 7 is a diagram illustrating an example of the position table 520. The position table 520 stores the current position P in association with each motorcycle 20.
As described with reference to FIG. 2, the position P is represented by the distance d from the start point 11 along the center line 12 of the race course 10 and the distance w from the center line 12 of the race course 10.
Based on the position table 520, the relative distance calculation unit 412 obtains the relative distance D between the host vehicle 20a and the leading enemy vehicle 20c. The contents are updated by the position calculation unit 415 for each frame.
[0061]
FIG. 8 is a diagram illustrating an example of the speed table 530. The speed table 530 stores a speed v before adjustment and a speed v ′ after adjustment in association with each motorcycle 20.
The speed v before the adjustment is based on the position P and the speed one frame before (the speed v ′ after the adjustment), the operation instruction from the input unit 200, the performance set for each of the motorcycles 20, and the like. The speed calculated by the game calculation unit 410.
Further, the adjusted speed v ′ is a speed obtained by the speed adjusting unit 414 adding the speed adjustment amount Δv calculated by the speed adjustment calculating unit 413 to the speed v before adjustment. Based on the adjusted speed v ′, the position P of the motorcycle 20 is calculated by the position calculation unit 415.
[0062]
The speed adjustment calculation formula 540 is a calculation formula for obtaining the speed adjustment Δv of the enemy vehicle 20b, and is, for example, the function f shown in FIG.
[0063]
Next, the operation of the game apparatus 100 will be described.
FIG. 9 is a flowchart for explaining the speed adjustment processing. This speed adjustment process is a process executed by the game calculation unit 410 according to the speed adjustment program 550 for each frame.
Before executing this process, the current speed (before adjustment) is determined for each motorcycle 20 based on the position coordinates and speed one frame before, the operation instruction from the input unit 200, and the performance set for each. (Corresponding to the speed v)).
[0064]
In the figure, first, the leading enemy vehicle identifying unit 411 identifies the leading enemy vehicle 20c with reference to the ranking table 510 (step S11).
That is, for example, in the order table 510 shown in FIG. 6, the first-ranked motorcycle is “enemy vehicle A”, and therefore the top enemy vehicle specifying unit 411 specifies “enemy vehicle A” as the top enemy vehicle 20c. Further, when the first-ranked motorcycle 20 is the “own vehicle”, the second-ranked motorcycle is identified as the top enemy vehicle 20c.
[0065]
When the first enemy vehicle 20c is identified, the relative distance calculation unit 412 then obtains the relative distance D between the identified first enemy vehicle 20c and the host vehicle 20a (step S12). Next, the speed adjustment amount calculation unit 413 obtains a speed adjustment amount Δv based on the speed adjustment amount calculation expression 540 (step S13).
[0066]
Then, the game calculation unit 410 arbitrarily selects one enemy vehicle 20b as a speed adjustment target from among a plurality (seven) enemy vehicles 20b (step S14), and sets the selected enemy vehicle 20b as the enemy vehicle 20b. On the other hand, the following processing (steps S15 to S17) is performed to adjust the speed.
[0067]
That is, the speed adjustment unit 414 refers to the speed table 530 and adds the speed v of the selected enemy vehicle 20b and the speed adjustment Δv obtained in step S13. Then, the adjusted speed v ′ obtained is stored in a predetermined position of the speed table 530 (step S15).
Next, the position calculation unit 415 refers to the speed table 530, performs a movement calculation for one frame based on the adjusted speed v ′, and obtains the obtained coordinate value of the position P after the movement in the position table 520. Store in a predetermined position (step S16).
[0068]
Thereafter, when there is an enemy vehicle 20b that has not yet been subjected to speed adjustment (step S17: NO), one enemy vehicle 20b is further selected (step S18). Then, the process proceeds to step S15, and the same process (speed adjustment and position update) is performed on the selected enemy vehicle 20b.
[0069]
When the above-described processing (steps S15 to S17) is performed for all enemy vehicles 20b (step S17: YES), the game calculation unit 410 is based on the updated position table 520 so that the rank of the motorbike 20 after movement is obtained. The rank table 510 is updated (step S19).
If the above process is performed, the game calculating part 410 will complete | finish this process.
[0070]

[0081]
Further, specific examples of realizing the game device 100 of the present embodiment are not limited to the above-described arcade game device or home game device, but include, for example, a portable game device, a personal computer, a portable terminal (including a mobile phone). Of course, it can be applied to a kiosk terminal or the like.
[0082]
Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention. For example, the following modifications can be considered.
[0083]
(A) The speed of the enemy vehicles located in the nearest neighborhood is individually adjusted.
In the above embodiment, the traveling speed is uniformly adjusted for all enemy vehicles. However, an enemy vehicle located nearest to the host vehicle 20a (hereinafter referred to as “nearest neighbor enemy vehicle”). The speed may be adjusted individually.
[0084]
That is, in step S11 of FIG. 9, along with the identification of the leading enemy vehicle 20c, the game calculation unit 410 (or the nearest enemy vehicle specification unit (not shown) included in the game calculation unit 410) specifies the nearest enemy vehicle. To do.
In step S15, the game calculation unit 410 determines whether or not the enemy vehicle 20b selected as the speed adjustment target is the nearest enemy vehicle specified in step S11.
[0085]
If it is determined that the vehicle is the nearest enemy vehicle, the relative distance calculation unit 412 obtains a relative distance D ′ between the host vehicle 20a and the selected enemy vehicle (nearest neighbor enemy vehicle) 20b. Next, the speed adjustment calculation unit 413 obtains a speed adjustment Δv ′ according to the speed adjustment calculation formula 540 based on the relative distance D ′. Thereafter, similarly, speed adjustment and position update are performed.
[0086]
As a method for identifying the nearest neighbor vehicle, for example, there are the following methods.
In other words, the relative distance from the host vehicle 20a is obtained from the rank table 510 for each of the two enemy vehicles 20b located before and after the host vehicle 20a. Then, the enemy vehicle 20b having the smaller absolute value of the obtained relative distance is set as the nearest enemy vehicle.
[0087]
Thus, by adjusting the speed individually for any enemy vehicle, for example, it is possible to produce a close battle between the host vehicle 20a and the nearest enemy vehicle.
[0088]
Further, the enemy vehicle whose speed is individually adjusted is not limited to the nearest enemy vehicle, and may be an arbitrary enemy vehicle 20b, or may include a plurality of enemy vehicles (the nearest enemy vehicle may or may not be included). .) 20b may be applied.
[0089]
(B) Switching between speed adjustment and non-speed adjustment.
Whether or not to adjust the speed of the enemy vehicle 20b may be determined based on a given criterion. The conditions include, for example, the player's play level, the elapsed time and number of laps of the race, the relative distance between the host vehicle 20a and the leading enemy vehicle 20c, the number of enemy vehicles 20b around the host vehicle 20a, and the like.
[0090]
Specifically, for example, a plurality of levels such as beginner level, intermediate level, and advanced level are set as play levels. When the player's play level is a beginner or intermediate level, the speed is adjusted. On the other hand, when the player is an advanced level, the speed is not adjusted.
[0091]
For example, the speed adjustment is performed when a predetermined time has elapsed from the start of the race or when a predetermined number of laps have been completed. In other words, speed adjustment is not performed at the beginning of the race, and when the end of the race is approached, execution of speed adjustment is started. it can.
[0092]
For example, when the relative distance D between the host vehicle 20a and the leading enemy vehicle 20c exceeds a predetermined distance, the speed adjustment is performed. For example, by adjusting the speed when the own vehicle 20a is temporarily delayed from the enemy vehicle 20b due to a crash or the like, the own vehicle 20a can quickly catch up with the enemy vehicle 20b.
[0093]
Further, the speed is adjusted according to the number of enemy vehicles 20b located within a predetermined distance from the host vehicle 20a. That is, since the speed of the enemy vehicle 20b is adjusted uniformly, the host vehicle 20a can escape from a group of dense enemy vehicles 20b by adjusting the speed of the enemy vehicle 20b.
[0094]
Further, when the virtual camera follows the player character, the predetermined distance is set to be within the range of the visual field of the virtual camera, so that the number of bikes 20 to be drawn when generating the game image can be reduced. It is possible to reduce the amount of processing load related to drawing without drawing a predetermined number or more of motorcycles 20.
[0095]
(C) Change the speed adjustment.
When performing the speed adjustment, the degree of adjustment may be changed. Specifically, a plurality of calculation formulas (speed adjustment calculation formula 540) for obtaining the speed adjustment Δv are prepared, and the calculation formula to be adopted is changed according to the conditions.
That is, for example, by adopting an arithmetic expression in which the speed adjustment Δv increases more as the race time elapses, the speed is adjusted more strongly as the end of the race is approached. This makes it possible to produce effects such as a large reversal of a delayed player and a more heated close battle at the end of the race.
[0096]
(D) The speed of the own vehicle 20a is adjusted.
In the present embodiment, the speed of the enemy vehicle 20b is uniformly adjusted, but the speed of the host vehicle 20a may be adjusted.
Specifically, in the same manner as the speed adjustment of the enemy vehicle 20b, the speed adjustment Δv is obtained from the relative distance D between the host vehicle 20a and the leading enemy vehicle 20c according to the speed adjustment calculation formula 540, and adjust. Thereby, for example, when the speed of the host vehicle 20a is increased, the speed of the enemy vehicle 20b is relatively increased.
[0097]
The speed adjustment calculation formula 540 employed at this time employs a calculation formula whose sign is opposite to that of the calculation formula applied to the enemy vehicle 20b. That is, for example, when the function f shown in FIG. 4 (applied to the enemy vehicle 20b) is applied to the host vehicle 20a, the following function f ′ is adopted.
f ′ = − f
This is because, for example, when the host vehicle 20a precedes the leading enemy vehicle 20c, the speed of the enemy vehicle 20b is decreased, that is, the speed of the host vehicle 20a is relatively increased.
[0098]
(E) How to obtain the speed after adjustment.
The method of obtaining the adjusted speed applied to the enemy vehicle 20b is not limited to the above-described method.
For example, from the relative distance D between the host vehicle 20a and the leading enemy vehicle 20c and the speed v of both vehicles, the leading enemy vehicle 20c can catch up with the leading enemy vehicle 20c after a predetermined frame. Find the speed of. And it is good also as applying this calculated | required speed uniformly with respect to the enemy vehicle 20b.
[0099]
(F) Applies to other than player characters.
The character that can be the host vehicle 20a may not be a character (player character) to be operated by the player.
Specifically, for example, it is assumed that the operation of the motorcycle 20 running on the race course 10 is controlled by a computer, and the player selects one of these motorcycles 20 to give a medal Suppose you enjoy this game by betting. In such a case, the present invention may be applied assuming that the motorcycle selected by the player corresponds to the own vehicle 20a in the present embodiment.
[0100]
