The present invention is characterized by control on a course in a car racing game using an automobile as an embodiment, which is executed by the game apparatus shown in FIG.

FIG. 2 is a diagram for explaining the control according to the present invention executed in the game device of FIG. 1, and is a schematic view of a course cross section.

A large undulation (jump base) 101 is formed at a predetermined position on the course 100. A car 110 controlled by a player travels on a course 100 in the direction of an arrow.

The CPU 11 as the control means grasps the jump position of the car of the jump base 101, for example, the coordinate position in the virtual three-dimensional space of the highest position of the jump base 101 for each frame, and holds it in the system memory 12 according to the game program.

FIG. 3 is a diagram showing a processing flow at the point of the jumping base 101 when the car 110 travels on such a course 100.

Explaining based on FIG. 3, when the game is started, the CPU 11 determines whether or not the car 110 is passing through a point that is a coordinate position in the virtual three-dimensional space of the highest position of the jump base 101 (step S1). .

Here, each object in the three-dimensional space including the course 100 and the car 110 is formed by a plurality of polygons, and the vertices of each polygon have (x, y, z) coordinate values in the virtual three-dimensional space. ing. Further, a virtual wall (screen) that is not displayed is formed at the highest position of the jump base 101 on the course 100.

Therefore, the CPU 11 determines whether or not the coordinates set on the car 110 (coordinates indicating the position of the object in the virtual three-dimensional space) match the coordinate position of the invisible wall set at the highest position of the jump base 101. To determine whether or not the car 110 is passing the point (step S1).

Further, when it is determined that the car 110 is passing the point (Step S1, Yes), the speed when passing the point of the car 110 is obtained, and it is determined whether or not the speed is equal to or higher than the predetermined speed ( Step S2).

The speed of the car 110 is controlled by acceleration based on a signal corresponding to the depression / depression of the accelerator pedal, which is an operation means installed in the main body imitating the driver's seat where the player rides, and is controlled by the signal corresponding to the depression of the brake pedal. Is done. The speed setting method for the vehicle 110 is determined depending on the program in car racing.

In the determination in the previous steps S1 and S2, when the passing point is not passed (step S1, No) and when the passing speed does not exceed the predetermined speed (step S2, No), the normal state Drive control (step S3).

That is, in the normal state of the drive control, the vehicle 110 is accelerated by the amount of depression of the accelerator pedal operated by the player as described above and is decelerated by the amount of depression of the brake according to the game program. Further, the traveling direction of the vehicle 110 is determined by the rotation of the steering wheel, and the deceleration process is further performed by the brake pedal.

Note that before the point, the player can use the boost function to increase the speed when passing the point. The player, together with the accelerator pedal, predicts the passing point and turns on the boost button. Thus, according to the program, the CPU 110 can set the acceleration of the car 110 to be larger, and thereby the car 110 can pass through the car 110 at a predetermined speed or higher.

On the other hand, in step S3, when the speed of the vehicle 110 when passing through the point exceeds the predetermined speed (step S2, Yes), drive control in a special state is performed (step S4).

FIG. 4 is a process flow of such special state drive control.

In FIG. 4, when the special state drive control is set, the special posture control is enabled (step S40).

This special posture control is control when the vehicle 110 jumps out from the jumping base 101 at a predetermined speed or more and the vehicle 110 is in a flight state. The vehicle 110 is tilted back and forth (pitching) or tilted left and right (rolling) depending on the control state. ) State. Therefore, when the car 110 lands on the course, the player controls the forward / backward inclination (pitching) or the left / right inclination of the car 110 so that the vehicle body lands parallel to the course 100. become.

In the normal state as described above, the operation means are used to change the direction of the left and right, the accelerator pedal is used to increase the moving speed, and the brake pedal is used to control the decrease in moving speed.

On the other hand, as an embodiment, the special attitude control uses operation means as follows.

That is, the steering wheel is used to control the roll (left / right tilt), and the accelerator pedal is used to control the pitch (front / back tilt).

Here, as a premise, the CPU 11 performs the following processing for each frame of the image.

A line is drawn vertically in a three-dimensional space from the coordinates of a plurality of parts set in the car 110 (for example, parts corresponding to four tires of the car 110 as shown in FIGS. 5 and 6) Find the coordinate point that intersects the top surface (ground).

FIG. 5 and FIG. 6 are diagrams showing examples of the state of the left and right inclinations and the front and rear inclinations of the car 110 that is jumped out of the jumping base 101 and is in the air.

5A shows a state in which the left and right tires are both in contact with the ground of the course 100, FIG. 5B shows a state in which the left tire is separated from the ground of the course 100, and FIG. (E) shows a state in which the left tire is separated from the ground of the course 100, (d) shows a state in which the course 100 is inclined, but both left and right tires are in contact with the ground of the course 100. The course 100 is tilted and the left tire is away from the ground of the course 100.

Similarly, in FIG. 6, (a) shows a state where the front and rear tires are both in contact with the ground of the course 100, (b) shows a state where the front tire is separated from the ground of the course 100, ( c) shows a state in which the rear tire is separated from the ground of the course 100, and (d) shows a state in which the course 100 is tilted but both the front and rear tires are in contact with the ground of the course 100. (E) shows a state in which the course 100 is inclined and the rear tire is separated from the ground of the course 100.

As described above, a line is drawn directly from each of the four tires, and the three-dimensional coordinates of the point in contact with the ground of the course 100 are obtained. The coordinate points of the four tires whose lines are drawn directly below are also grasped by the CPU 11 for each frame according to the game program.

Therefore, the distance from the ground of the course 100 of each of the four tires can be easily obtained by calculation by the CPU 11.

Thereby, based on the distance from the ground of the course 100 of each of the four tires obtained by the CPU 11, it is possible to determine the degree of forward / backward inclination and left / right inclination when the vehicle 110 lands on the course 100. .

Returning to the flow of FIG. 4, it is determined whether the forward / backward inclination of the car 110 is parallel to the ground of the course 100 based on the inclination of the car 110 obtained by calculation as described above (step S41). When it is not parallel (step S41, No), it is determined as bad landing (step S41A).

When it is determined that the forward / backward inclination of the car 110 is parallel to the ground of the course 100 (step S41, Yes), it is determined whether the left / right inclination of the car 110 is parallel to the ground of the course 100 (step S42). .

If the forward / backward inclination is parallel to the ground of the course 100 but the left / right inclination is not parallel to the ground of the course 100 (No in step S42), it is determined that the landing is good (landing) (step S42A).

Next, when the forward / backward inclination and the left / right inclination are parallel to the ground of the course 100 (step S42, Yes), it is further determined whether or not it is the maximum flight distance (step S43).

If the jumping speed from the jumping base 101 and the boost button are pressed at this time, further acceleration is given and the flight distance can be increased.

When the maximum flight distance is not reached (step S43, No), it is determined as excellent landing (step S43A), and when it is the maximum flight distance (step S43, Yes), the best landing (amazing landing) Determine (step S43B).

Further, as a benefit, control may be performed so as to give additional acceleration to the car 110 after landing according to each of the above determination results.

Also, the flight landing points a, b, and c can be arbitrarily determined by a combination of the jumping speed from the jumping base 101 and the attitude of the car 110 during the jump to the global coordinates in the virtual three-dimensional space.

For example, as the posture of the car 110 is closer to the horizontal (parallel to the x and z planes), the falling speed is suppressed.

Furthermore, as a practical example, it is possible to automatically switch the virtual viewpoint when transitioning to jumping, thereby facilitating the player's operation.

In the normal drive control (step S3), the line-of-sight camera placed in the virtual three-dimensional space is positioned on the car 110 to be operated by the player, and the image shows the other car that the player runs ahead from the own vehicle. It becomes an image.

On the other hand, when the drive control is possible in the special state (step S40), the viewpoint camera is controlled to be switched to the overhead view viewpoint. Thereby, the posture operation of the car 110 operated by the player can be facilitated.

For example, the distance Z value between the viewpoint camera and the car 110 operated by the player in the virtual three-dimensional space is increased from 0 to Z during the elapse of a predetermined time. As a result, the car 110 can move away from the viewpoint camera and view the car 110 flying from the jump stand 101 from an overhead view.

FIG. 7 is an example of a display image when the car 110 operated by the player is observed from an overhead viewpoint.

The player can observe the posture of the car 110 by looking at the image of the car 110 to be operated. At this time, as shown in FIG. 7, as an aid to the player's operation, the direction to be operated, that is, the direction 20 of the left / right tilt control, the direction 21 of the front / rear tilt control, and an icon indicating the operation means are displayed. Is displayed.

As described above, according to the present invention, in the racing game, it is possible to provide the player with fun by disposing the jump stand 101 on the course and enabling operation control different from the normal running at the time of the jump.
