Further, a communication I / F 114 is connected to the bus arbiter 107, and the other end of the communication I / F 114 is connected to a network, and is connected to another video game apparatus and a management server.

  FIG. 2 is a diagram showing an example of a functional configuration realized mainly by a computer program of the video game apparatus 1.

  In FIG. 2, the video game apparatus 1 includes a game control unit 121, an evaluation calculation unit 122, an acceleration / deceleration control unit 123, a position / time table 124, and an evaluation holding unit 125.

  The game control unit 121 has a function of controlling the progress of the video game.

  The evaluation calculation unit 122 receives, from the game control unit 121, a position signal (for example, coordinate values of X, Y, Z, etc.) indicating the current position of the object such as an automobile, and a time indicating the elapsed time from the start. Signal (for example, number of seconds, number of frames from the start, etc.), distance signal indicating the distance traveled from the start, and the depth of the wall collision indicating the situation of a collision (hit) on the side of the course A signal, a steerover angle signal indicating excessive steering, and a drift angle / velocity signal indicating a drift state are input, and an evaluation (point) value is calculated and stored in the evaluation holding unit 125 in real time. It has a function. Evaluation is the time to be added to or subtracted from the goal arrival time (standard goal time) when the vehicle travels normally. FIG. 3 is a diagram showing an example of a correspondence relationship between the evaluation and the goal arrival time. When the evaluation is “0”, the influence on the goal arrival time is “0” seconds. Is subtracted, and the lower the evaluation, the more seconds are added to the goal arrival time.

  Returning to FIG. 2, the position / time table 124 holds the correspondence between the standard travel distance (standard distance) and the elapsed time (standard transit time) at each position (pass) on the course. Reference is made in the evaluation calculation in 122 and the acceleration / deceleration control in the acceleration / deceleration control unit 123. Each position (pass) is set to a standard traveling position on the course.

  FIG. 4 is a diagram showing an example of a course (circuit) in a racing game, and FIG. 5 is a graph showing the relationship between the travel distance (standard distance) and the elapsed time (standard passage time) on the course stored in the position / time table 124. It is a figure which shows an example. The travel distance (standard distance) and the elapsed time (standard passage time) stored in the position / time table 124 are games as the travel distance (standard distance) and the elapsed time (standard passage time) when performing standard travel. This value is set by the developer in advance. In FIG. 5, the relationship between the position (distance) and time is shown continuously. However, on the position / time table 124, the traveling distance ( Data of a pair of standard distance) and elapsed time (standard transit time) is stored. FIG. 6 is a diagram showing an example of the position / time table 124, in which path coordinates (x, y, z), travel distance, standard passage time, and set passage time are stored in correspondence. Here, the set transit time is calculated based on the goal arrival time (set goal time) set by the evaluation, and is sequentially updated when the value of the evaluation is changed. The set passage time in the figure is an example in which the evaluation value is high and each passage time is shorter than the standard passage time.

  Returning to FIG. 2, the acceleration / deceleration control unit 123 receives the position signal and time signal acquired from the game control unit 121 via the evaluation calculation unit 122, the reference value of the position / time table 124, and the evaluation held in the evaluation holding unit 125. And a display speed control for accelerating / decelerating the display speed displayed on the game screen of the object, and a physical speed control signal for accelerating / decelerating the physical speed that is not displayed on the game screen of the object. It has a function of giving a signal and a wall deceleration control signal for reducing / restoring wall deceleration in response to a wall hit, and controlling the speed of the object.

<Operation>
FIG. 7 is a flowchart showing an example of main control processing of the above embodiment.

  In FIG. 7, in parallel with the progress of the game, the evaluation calculation (step S1) and the acceleration / deceleration control (step S2) are repeated, for example, every other frame (1/60 seconds). Note that each position (path coordinate) described above may be defined as a straight line crossing the course, and processing may be performed at each timing when the object passes through the straight line.

  FIG. 8 is a flowchart showing a processing example of the evaluation calculation (step S1 in FIG. 7) by the evaluation calculation unit 122.

  In FIG. 8, when the evaluation calculation unit 122 starts the evaluation calculation process (step S101), the evaluation calculation unit 122 determines whether or not there is a wall hit based on the wall collision depth signal acquired from the game control unit 121 (step S102). If it is determined that there has been a wall hit (Yes in step S102), the evaluation value held in the evaluation holding unit 125 is decreased by a predetermined value (step S103). Since the wall hit is an operation to be deducted, the skill evaluation is lowered. If it is not determined that there has been a wall hit (No in step S102), no particular processing is performed.

  Next, the evaluation calculation unit 122 compares the position (pass) closest to the current position indicated by the position signal acquired from the game control unit 121 with the coordinate value based on the position signal of the object acquired from the game control unit 121 and the pass coordinate value. And find the closest path. Then, the travel distance (standard distance) of the position (path) is compared with the current distance indicated by the distance signal acquired from the game control unit 121, and whether or not the current distance is smaller than the travel distance (standard distance). If it is determined (step S104) and it is determined that the current distance is smaller than the standard distance (Yes in step S104), the evaluation value held in the evaluation holding unit 125 is increased by a predetermined value (step S105). The fact that the current distance is smaller than the standard distance means that the skill is evaluated as a result of the operation to be added because it is running on an advantageous traveling line whose distance is smaller than the standard traveling line. If it is not determined that the current distance is smaller than the standard distance (No in step S104), the evaluation value is decreased by a predetermined value (step S106). The fact that the current distance is not smaller than the standard distance means that the driving is wasted compared to the standard driving line, so the evaluation of the skill is lowered as a result of the operation to be deducted.

  Next, the evaluation calculation unit 122 determines whether or not the steering is excessively cut based on the steering over angle signal acquired from the game control unit 121 (step S107), and determines that the steering is excessively cut (Yes in step S107). The evaluation value held in the evaluation holding unit 125 is decreased by a predetermined value (step S108). Since steering too much is an operation to be deducted, the skill evaluation is lowered. If it is not determined that the steering is excessively cut (No in step S107), no particular processing is performed.

  Next, the evaluation calculation unit 122 determines whether or not effective drift has been performed based on the drift angle / speed signal acquired from the game control unit 121 (step S109), and determines that effective drift has been performed (step S109). No)), the evaluation value held in the evaluation holding unit 125 is increased by a predetermined value (step S110). Since effective drift is an operation to be added, the skill evaluation is raised. When it is not determined that an effective drift has been made (No in step S109), no particular processing is performed. Thereafter, the evaluation calculation unit 122 ends the evaluation calculation process (step S111).

  FIG. 9 is a flowchart showing a processing example of acceleration / deceleration control (step S2 in FIG. 7) by the acceleration / deceleration control unit 123.

  In FIG. 9, when the acceleration / deceleration control unit 123 starts the acceleration / deceleration control process (step S <b> 21), the setting passage stored in the position (path) closest to the current position of the object indicated by the position signal from the position / time table 124. The time and the time to the current position (current time indicated by the time signal) are compared to determine whether or not the former is small (step S22). If it is determined that the set transit time is less than the current time (Yes in step S22), the object is accelerated (step S23). If it is determined that the set transit time is not less (No in step S22), the object is decelerated. This is performed (step S24). Thereafter, the acceleration / deceleration control unit 123 ends the acceleration / deceleration control process (step S25).

  FIG. 10 is a flowchart showing a processing example of acceleration (step S23 in FIG. 9) and deceleration (step S24 in FIG. 9).

  In FIG. 10, when the acceleration / deceleration control unit 123 starts the process (step S201), the acceleration / deceleration of the physical speed that is not displayed on the speedometer on the game screen of the object (step S202). The speedometer value at this time is displayed as a normal value calculated from the input time of the accelerator input operation section, input adjustment, or the like. In this case, it is desirable that acceleration and deceleration of the physical speed of the object be performed within a range of a predetermined ratio that is not noticed by the player, for example, within a range of ± 10% of the speed displayed by the speedometer. When the difference between the set passing time and the current time described above is large, acceleration / deceleration can be performed up to 10%, and when the difference is small, acceleration / deceleration can be performed at a rate corresponding to the difference.

  FIG. 11 shows the concept of the correction action by acceleration / deceleration control for approaching the evaluation position, considering the position (evaluation position) in consideration of the evaluation of an object such as a car on the course at the current time. FIG. For example, each path described above may be set by dividing a standard traveling position from the start to the standard goal time every frame (1/60 seconds). That is, the standard passage time of each path described above is set in unit time. At this time, if the standard goal time is 5 minutes 00 seconds, 18000 passes are set at the standard running position on the course. In this case, the standard goal time and the set goal time in the position / time table 124 are also set as the number of frames. Thereby, the current time can be converted as the number of frames from the start, and the position of the path where the object should be with respect to the current time (number of frames) can be indicated as the evaluation position P0 in FIG. The evaluation position P0 is the position (coordinates) of the path where the current time (number of frames) is set as the set transit time. In this case, S22 in FIG. 9 is accelerated / decelerated by comparing the pass number closest to the object at the current time (number of frames) with the pass number of the evaluation position P0 based on the passes numbered in order by the travel distance. Processing can also be performed.

  In FIG. 11, it is assumed that an object is present at the current position P1 on the course and is moving in the direction of the thick arrow. If the evaluation position P0 that takes the evaluation into consideration at this time exists first, the object approaches the evaluation position P0. Accelerated in the direction. Thereby, the time of the set passing time at each position (pass) on the course approaches, and the goal time converges to the set goal time. Also, if the object is present at the current position P2 on the course and is moving in the direction of the thick arrow, and there is an evaluation position P0 that takes into account the evaluation at this point, the object is decelerated in a direction approaching the object evaluation position P0 The Also in this case, the time of the set passing time at each position (pass) on the course approaches and the goal time converges to the set goal time.

  Returning to FIG. 10, the acceleration / deceleration control unit 123 can also accelerate and decelerate the display speed displayed on the game screen of the object and also displayed on the speedometer, in parallel with the acceleration of the physical speed (step S202). (Step S203). In other words, it may be difficult to guide to the evaluation position of the current time taking into account the evaluation only by acceleration / deceleration of the physical speed in a range not noticed by the player (range of ± 10%). By performing this together, it is easy to guide (correct) the object to the evaluation position in consideration of the evaluation. In this case, acceleration and deceleration of the display speed are also performed within a range of a predetermined ratio that is not noticed by the player, for example, within a range of ± 10% of the speed that the object can exert (depending on the set ability value). Is desirable. When the difference between the set passing time and the current time described above is large, acceleration / deceleration can be performed at a maximum of 10%, and when the difference is small, acceleration / deceleration can be performed at a rate corresponding to the difference.

  Further, the acceleration / deceleration control unit 123 can reduce / return wall deceleration in parallel with the acceleration of the physical speed (step S202) (step S204). That is, in the game progress by the game control unit 121, a process of performing a predetermined amount of deceleration is generally performed when an object comes into contact with the side wall of the course, but this deceleration is instead guided to an evaluation position that takes into account the evaluation. Cause difficulty. Therefore, when acceleration is high and acceleration should be performed, wall deceleration is also reduced, and when evaluation is low and deceleration should be performed, return to wall deceleration is performed, leading to an evaluation position that takes evaluation into account. It is easy.

  Thereafter, the acceleration / deceleration control unit 123 ends the acceleration or deceleration process (step S205).

  In the above-described embodiment, the evaluation calculation is performed over the entire game progress, and the object is accelerated or decelerated based on the evaluation value. However, the object acceleration or deceleration control based on the evaluation value is controlled in the course. It can also be performed limited to a predetermined area or a predetermined time zone from the start of the game. In this case, in an area where the object is not accelerated or decelerated based on the evaluation value, the player's operation is directly reflected in the progress of the game. Can do. Even in this case, by accelerating or decelerating the object based on the evaluation value in other areas, the lap time and the running time can be induced to values according to the skill of the player.

<Summary>
As described above, the embodiment of the present invention has the following advantages.
(1) The lap time and running time are not affected by the speed of the object in progress of the game, and the skill of the player can be accurately evaluated and reflected in the lap time and running time.
(2) Since it becomes easier for objects to travel within the range of time and the position that goes back and forth in the evaluation according to the skill centered on the standard pattern, the game can be managed with the evaluation system prepared on the development side it can.
(3) When competing with other video game devices via the network, if the opponent's running data cannot be acquired due to communication interruption, the conventional game data was used to compensate for subsequent game progress. However, a simulation close to actual running data can be performed by using the evaluation of the opponent player acquired immediately before the communication interruption.
(4) Even if there is a difference in the performance (acceleration, maximum speed, cornering ability) set for the object, the difference can be absorbed by the present invention, and a close battle is produced in a time attack or multiplayer battle. Can be easily done.
