Description

The present invention relates to a game program and a game device.

As one genre of video games, there is a racing game in which a virtual car is driven in a virtual space to compete for driving time, etc., and it is deeply popular. Many racing games can be enjoyed not only on home-use and arcade-type game machines but also on mobile terminals such as smartphones.

Recently, improvements in simulation technology have realized operability close to that of an actual vehicle, and advanced operation techniques are required to aim for a high score. Therefore, there is a big difference between the expert and the beginner, and the beginner cannot clear the stage, and there is a problem that the beginner stops before the fun of the game is understood. However, easily lowering the difficulty level for beginners is not satisfactory for experts and is unpopular, so it is a mess.

Therefore, there is a technique for providing various assists for beginners while maintaining a high level of operability for skilled workers (see Patent Document 1 and the like).

The function of the game device 1 described with reference to FIG. 1 is realized by executing a predetermined program on the processor 103. The program may be acquired via a recording medium, may be acquired via a network, or may be embedded in a ROM.

<Operation>
FIG. 3 is a flowchart showing a processing example of the above embodiment, and shows assist during traveling.

In FIG. 3, when the process is started, the game progress control unit 12 acquires the current traveling position of the vehicle body and the reference line data (step S1). The current running position of the vehicle body is represented by three-dimensional coordinates on the course in the virtual space. The reference line data is, for example, data acquired in advance when the developer side performs a model run on a course in the virtual space.

FIG. 4 shows an example of reference line data, and the point ID on the course includes coordinate values (three-dimensional coordinates), reference vehicle speed, distance from a reference position (for example, a start point), elapsed time from the reference position, and the like. Are associated with each other. The point ID may be assigned so that the elapsed time from the reference position is at a predetermined time interval, or the point ID may be assigned so that the distance from the reference position is at a predetermined interval.

Returning to FIG. 3, the game progress control unit 12 acquires the current vehicle speed (speed) vector of the vehicle body from the vehicle body simulator 13 (step S2).

Next, the game progress control unit 12 calculates a traction force vector for correcting the traveling position of the vehicle body to the reference line (for example, correcting the traveling position several sections ahead to match the reference line including the traveling direction). (Step S3).

FIG. 5 shows a case where the own vehicle is at a traveling position P slightly distant from the reference line L, and it is assumed that the vehicle speed (speed) vector V faces the direction shown in the drawing. In this case, it is necessary to correct the point P2 on the reference line L closest to the traveling position P to the point P2 several sections (predetermined value according to the performance of the vehicle body) starting from the point P1 including the traveling direction. The traction vector F is calculated. This traction force vector F can be calculated from the traveling position P, the points P1 and P2, the vehicle speed (speed) vector V, the mass of the vehicle body, the time for applying the external force (predetermined value), and the like.

Returning to FIG. 3, the game progress control unit 12 acquires the current steering wheel angle by the player operation (step S4), and is a ratio of applying the traction force vector F to the vehicle body from the steering wheel angle and the vehicle speed (already acquired). The blend ratio is calculated (step S5). It should be noted that the ON / OFF of the traction is determined in advance according to the difference between the reference vehicle speed and the acquired vehicle speed between steps S2 and S3, and if it is OFF, steps S3 to S6 are skipped. Good. Further, ON / OFF of the traction may be determined not only by the vehicle speed but also by the angle of the steering wheel. Further, the blending ratio may be any of a multi-step ratio and a two-step ON / OFF.

Returning to step S5, for example, when the handle angle is less than a predetermined value in both the right direction and the left direction, the blend ratio is set to 0. This is because when the steering wheel is facing the front (when the steering wheel angle is near 0), when assisting is performed, the vehicle body turns even though the steering wheel is not turned, and the player is assisted. This is because they notice and feel uncomfortable. For this reason, the assist is activated when the player rotates the steering wheel. Further, even when the vehicle speed does not decrease by more than a predetermined ratio from the reference vehicle speed of the reference line data, the blend ratio is set to 0. This is because even if the traveling position deviates from the reference, the vehicle speed is sufficient as compared with the reference vehicle speed, and a sufficient time can be set, so that assist is considered unnecessary.

Further, when the steering wheel angle exceeds a predetermined value in both the right direction and the left direction, and the vehicle speed is lower than the reference vehicle speed by a predetermined ratio, the magnitude of the steering wheel angle and the vehicle speed Increase the blend rate according to the rate of decrease. The reason why the blend ratio is increased according to the size of the steering wheel angle is that the player turns the steering wheel too much at a corner or the like, so that the traction force is increased and the correction is accelerated. The reason why the blend ratio is increased according to the rate of decrease in vehicle speed is that the vehicle speed is considerably lower than the standard vehicle speed, so that the traction force is increased and the correction is accelerated. Contrary to the above, if the speed is too high compared to the standard vehicle speed, it may be difficult for the steering wheel operation to be reflected in the rotation of the vehicle body and it may go off course, so in this case also the difference between the standard vehicle speed and the acquired vehicle speed. The blending ratio may be changed according to the above. Especially for beginners, the operation tends to be extreme, such as turning the steering wheel or stepping on the accelerator more than necessary, and it is necessary to detect such a state and assist.

Returning to FIG. 3, the game progress control unit 12 gives an instruction to apply an external force corresponding to the force obtained by multiplying the traction force vector by the blend rate to the vehicle body simulator 13 (step S6). The time for applying the external force is the time for applying the external force when the traction force vector is calculated.

Next, the game progress control unit 12 displays the screen based on the simulation result of the vehicle body simulator 13 and the like (step S7). In parallel with the screen display, voice such as engine sound is also output. FIG. 6 shows an example of screen display, in which the back surface of the own vehicle C is displayed in the center of the screen, and the gear position G indicating that the transmission is automatic (AT) in 5th speed is displayed at the lower left of the screen. A speedometer M1 indicating the vehicle speed and a tachometer M2 indicating the engine speed are displayed at the lower right.

Although the case where the correction is performed by applying the traction force to the vehicle body has been described, the correction may be performed on the steering wheel angle and the vehicle speed instead of the traction force. However, in the correction of the steering wheel angle, it is difficult to make a correction in the lateral direction in the traveling direction of the vehicle body, and the effect of the correction cannot be made very high. Further, in the correction of the vehicle speed, it is easy for the player to notice that the assist is being performed, so that the effect of the correction cannot be made very high.

In addition, when making corrections by adding traction force to the vehicle body, if the traction force is eliminated, it will be in a standard state and there is no need to perform special tuning for assist, which will contribute to the reduction of development man-hours. Can be done.

In the present embodiment, the same assist may be performed for any vehicle body selected in the vehicle body selection, but the number of vehicle bodies that can be used increases as the game progresses, and high-performance parameters and the like are set even for the same vehicle body. Since the tuning may be performed, the assist ON / OFF and the blend rate may be changed according to the selected vehicle body. By doing this, it is possible to actively assist the car body (the car body that can be used in the early stages of the game) handled by beginners who have just started the game, so beginners and experts can play at the same time. Even in the case of (competition), you will be able to focus on assisting beginners.
