  The three-dimensional video game according to this embodiment is assumed to be a game that progresses on a field provided in a virtual three-dimensional space. Note that the virtual three-dimensional space in which the field is formed is indicated by the world coordinate system. The field is composed of a plurality of surfaces, and the coordinates of the vertices of each component surface are represented as feature points.

Next, the operation of the video game apparatus 100 of this example will be described.
Here, in order to simplify the description, the description may be omitted except for the processing particularly related to the present invention. In this example, it is assumed that video game control for RPG is executed.

  FIG. 2 is a flowchart showing an example of main processing in the video game apparatus 100 of the present example. The main process is a process for generating an image for one frame and a process necessary for controlling the video game, and is executed in response to a timer interrupt every 1/30 seconds. Note that “every 1/30 seconds” is an example, and the main process may be executed in response to a timer interrupt for each field period (1/60 seconds), for example, depending on the amount of processing. It may be executed in response to a timer interrupt every (1/15 seconds).

  In the main process, the control unit 11 determines whether or not the game is instructed to start by operating the keypad 30 before the game starts, and changes the scene (for example, changes in the field) if the game is being executed. It is determined whether or not it is time to perform (step S101). The timing for changing the scene is, for example, in order to end a scene (for example, a scene represented by a virtual three-dimensional space) that has been displayed on the image display unit 51 so far and switch to a new scene. 51 indicates the timing for displaying a virtual three-dimensional space indicating a new scene.

  When it is determined that there is an instruction to start the game, or when it is determined that it is time to change the scene (Y in step S101), the control unit 11 performs an initial screen (an initial screen at the start of the game, The initial screen when changing the scene is determined (step S102). Various data such as screens and characters used in the game are stored in the storage medium 70.

  Next, the control unit 11 determines the position of the viewpoint of the virtual camera, the direction of the visual axis, and the size of the viewing angle according to the control program, and performs initial setting of the virtual camera for performing perspective transformation (step S103). Then, the process proceeds to step S115.

  When it is determined that the game is being executed and it is not time to change the scene (N in Step S101), the control unit 11 receives instruction data based on the operation of the keypad 30 by the player (Step S104). When instruction data for instructing an action related to movement is received in step S104 (Y in step S105), the control unit 11 executes a movement process according to the received movement instruction data (step S106). Movement information is generated based on the position information of the player character derived from the movement process (step S107). Then, the process proceeds to step S113.

  When the instruction data for instructing the action related to the battle is received in step S104 (Y in step S108), the control unit 11 executes a battle process in accordance with the received battle instruction data (step S109). Battle information is generated based on the battle result and battle progress determined by the battle process (step S110). Then, the process proceeds to step S113.

  When instruction data for other instructions is received in step S104 (Y in step S111), the control unit 11 performs processing (for example, conversation, shopping, picking up, etc.) according to the received other instruction data. This is executed (step S112), and other various information according to the processing result is generated. Then, the process proceeds to step S113.

  In step S113, the control unit 11 updates the current position of the player character by storing the movement information generated in step S107 in a predetermined data area of the RAM 12. Further, in step S113, the control unit 11 stores the battle information generated in step S110 and other information generated after step S112 in a predetermined data area of the RAM 12, thereby allowing the player character to perform various types of information. The action history is stored and retained.

  Next, the control unit 11 executes an action evaluation process based on the information indicating the action history of the player character once stored in the RAM 12 (step S114).

  Then, the control unit 11 perspective-transforms the virtual three-dimensional space including the player character and the non-player character to be displayed from the virtual camera on the virtual screen according to the setting contents of the virtual camera and the like on the image display unit 51. A display process for generating a two-dimensional image to be displayed is performed (step S115). When the display process is terminated, the main process is terminated. Thereafter, when a timer interrupt occurs at the start timing of the next frame period, the next main processing is executed. Then, by repeatedly executing the main process, the character image is switched for each frame period, and the moving image is displayed on the image display unit 51.

  Here, the display process in step S115 will be briefly described. In step S115, the control unit 11 firstly, among the coordinates of the vertices of the polygons constituting the virtual three-dimensional space including the player character and the non-player character, at least the vertices of the polygons included in the range to be perspectively transformed on the virtual screen. Is converted from coordinates in the world coordinate system to coordinates in the viewpoint coordinate system. Next, the control unit 11 transmits the coordinates of the vertices of the polygon in the viewpoint coordinate system for the player character and the non-player character to the graphic processing unit 15, and outputs a drawing command to the graphic processing unit 15.

  When a drawing command is input, the graphic processing unit 15 updates the contents of the Z buffer so that the point data on the front side remains for each point constituting each surface based on the coordinates of the viewpoint coordinate system. When the contents of the Z buffer are updated, the graphic processing unit 15 develops image data for the remaining points on the front side in the frame memory 19. The graphic processing unit 15 also performs processing such as shading and texture mapping on the developed image data.

  The graphic processing unit 15 sequentially reads the image data developed in the frame memory 19, adds a synchronization signal, generates a video signal, and outputs the video signal to the display device 50. The display device 50 displays an image corresponding to the video signal output from the graphic processing unit 15 on the image display unit 51. By switching the image of the image display unit 51 every frame time, the player can see an image including a state in which the player character and the non-player character move on the field.

  Next, character correction operation processing in the video game apparatus 100 of this example will be described. 3 and 4 are flowcharts showing an example of character correction operation processing in the video game apparatus 100 of the present example. It should be noted that explanations may be omitted except for processing particularly related to the present invention. This character correction operation process is a process realized by repeatedly executing the main process described above, and particularly summarizes the process related to the correction of the moving direction of the player character.

  In the video game apparatus 100 of the present example, the player character is instructed to move by operating the direction keys (for example, the cross key 31 and the left joystick 38) of the keypad 30 by the player. That is, the control unit 11 performs control for moving the player character in the direction (movement instruction direction) indicated by the operation of the direction key of the keypad 30. However, when the player character collides with an obstacle arranged in the game field, the control unit 11 performs the movement instruction direction indicated by the operation of the direction key according to the character correction operation process shown in FIGS. Controls to move the player character in different corrected directions.

  In the character correction operation process, the control unit 11 first determines whether or not the player character has collided with an obstacle such as a wall (step S201). In step S201, the control unit 11 moves in the movement instruction direction vector indicated by the operation of the direction key on the keypad 30 (the vector size is determined by the status of the player character and the like). Is added to the coordinates indicating the current position of the player character to obtain the coordinates of the planned movement position (movement target position), and the outer edge portion of the obstacle (for example, the obstacle is a wall on the line segment from the current position to the planned movement position). If it is, it is determined whether or not the walls (sides indicating the outer edge of the wall) intersect. The coordinate data of the outer edge portion of the obstacle is included in various data stored in the storage medium 70, read by the DVD / CD-ROM drive 16 in which the storage medium 70 is mounted, and the RAM 12. Is loaded.

  When it determines with having collided, the control part 11 confirms whether it is in correction mode (step S202), and if it is not correction mode, it will start correction mode (step S203). For example, the control unit 11 checks the setting state of the correction mode flag indicating whether or not the correction mode is set in step S202, and sets the correction mode flag that is in the off state to the on state in step S203.

  Next, the control part 11 specifies the angle of an obstruction (step S204). In this example, in step S204, in order to identify the angle of the obstacle at the collision position, a vector (arrangement direction vector) of the arrangement direction of the obstacle is specified. It should be noted that the arrangement direction vector is a vector that faces the outer edge of the obstacle at the intersection of the line segment from the current position of the player character to the planned movement position and the outer edge of the obstacle, and only the obstacle arrangement direction can be specified. For example, it is a unit vector. Further, the arrangement direction vector may be taken rightward (X positive direction) or leftward (X negative direction) in the game field coordinate system.

  Next, the control unit 11 stores the arrangement direction vector specified in step S204 in a predetermined storage area of the RAM 12 as the arrangement direction vector at the time of the previous collision (step S205).

  Next, the control unit 11 calculates the inner product of the obstacle arrangement direction vector identified in step S204 and the movement instruction direction vector directed to the movement instruction direction indicated by the operation of the direction key of the keypad 30 ( Step S206). Note that the direction indicated by the movement instruction direction vector does not necessarily match the direction indicated by the traveling direction vector that faces the traveling direction of the player character in the game field.

  Next, the control unit 11 determines the rotation direction of the player character according to whether the inner product value calculated in step S206 is positive or negative (step S207). Specifically, in step S207, if the inner product value is positive (including 0 in this case), the control unit 11 sets the direction indicated by the arrangement direction vector as the rotation direction, and if the inner product value is negative, the arrangement direction vector is The direction opposite to the direction shown is determined as the rotation direction. In step S207, “strong” is set as the rotation strength (the size of the rotation angle). When the rotation intensity is high, the rotation angle is relatively large, and the rotation action is executed so that the player character quickly approaches the direction along the obstacle.

  Next, if the inner product value calculated in step S206 is negative, the control unit 11 inverts the sign of the saved previous-collision arrangement direction vector (step S208).

  Next, the control unit 11 determines the movement position of the player character along the obstacle in the game field (step S209). In step S209, if it is determined in step S206 that the inner product value is positive, the control unit 11 determines a position along the obstacle in the direction indicated by the arrangement direction vector as the moving position, and in step S206, the inner product is determined. If it is determined that the value is negative, a position along the obstacle in a direction opposite to the direction indicated by the arrangement direction vector is determined as the movement position. That is, in step S209, the control unit 11 determines a position along the obstacle in the direction indicated by the previous collision arrangement direction vector as the movement position.

  Then, the control unit 11 updates the direction of the player character to a direction rotated by a predetermined angle in the rotation direction determined in step S207, and updates the position of the player character to a position moved by a predetermined distance to the movement position determined in step S209. The player character is displayed at the updated position in the game field in the updated direction (step S210). Specifically, the update of the direction of the player character in step S210 is, for example, calculating a difference angle between a direction indicated by a vector (PC direction vector) indicating the current direction of the player character and a direction indicated by the arrangement direction vector. Then, it is realized by executing a process of updating the PC direction vector in a direction rotated by a predetermined angle (for example, half of the difference angle) corresponding to the rotation intensity (strong).

  When it determines with it being in correction | amendment mode in step S202, the control part 11 specifies the angle of an obstruction similarly to step S204 (step S211). That is, in this example, in order to specify the angle of the obstacle at the collision position in step S211, a vector of the obstacle arrangement direction (arrangement direction vector) is specified.

  Next, the control unit 11 calculates the inner product of the arrangement direction vector identified in step S211 and the stored previous arrangement direction vector at the time of collision (step S212), and if the calculated inner product value is negative, the arrangement is performed. After inverting the sign of the direction vector (step S213), the arrangement direction vector at the time of the previous collision is updated to the arrangement direction vector (step S214). That is, the arrangement direction vector specified in step S211 or the vector obtained by inverting the sign of the arrangement direction vector specified in step S211 is set as a new previous-collision arrangement direction vector.

  Next, the process proceeds to step S209. In step S209 here, if it is determined in step S212 that the inner product value is positive, the control unit 11 moves the position along the obstacle in the direction indicated by the arrangement direction vector specified in step S211. If it is determined in step S212 that the inner product value is negative, a position along the obstacle in the direction opposite to the direction indicated by the arrangement direction vector is determined as the movement position. That is, in step S209, the control unit 11 determines a position along the obstacle in the direction indicated by the previous collision placement direction vector updated in step S214 as the movement position. And the control part 11 performs step S210.

  Next, the control unit 11 confirms the movement operation instruction direction by the direction key of the keypad 30 by the player, and if the movement operation instruction direction has not been changed (N in Step S215), the process returns to Step S201. On the other hand, if the movement operation instruction direction by the direction key of the keypad 30 by the player has been changed (Y in step S215), the control unit 11 proceeds to step S222. That is, if the movement operation instruction direction by the direction key operation is continued without being changed (if the same operation is continuously performed), the process returns to step S201.

  By repeatedly executing the above-described steps S201 to S215, even if the same operation of the direction key of the keypad 30 is continued, even if it collides with an obstacle arranged on the game field, the direction of the player character ( (Direction) and the moving position are corrected smoothly, and the player character can be operated smoothly.

  If it is determined in step S201 described above that there is no collision, the control unit 11 checks whether or not the correction mode is in effect (step S216). If not in the correction mode, the control unit 11 returns to step S201. That is, in the character correction operation process, the control unit 11 monitors whether or not the player character has collided with an obstacle when not in the correction mode (steps S201 and S216).

  If in the correction mode, the control unit 11 determines the rotation direction of the player character so as to rotate in the direction approaching the movement operation instruction direction (direction indicated by the movement instruction direction vector) by the direction key operation of the keypad 30. (Step S217). In addition, the control unit 11 sets “weak” as the rotation strength (the size of the rotation angle) (step S218). When the rotation intensity is weak, the rotation angle is relatively small, and the rotation operation is executed so that the direction of the player character gently approaches the direction of the movement operation instruction by the direction key operation of the keypad 30.

  Next, the control unit 11 determines the movement position of the player character at a position toward the movement operation instruction direction (direction indicated by the movement instruction direction vector) by the direction key operation of the keypad 30 (step S219).

  Then, the control unit 11 updates the direction of the player character to a direction rotated by a predetermined angle (an angle corresponding to the rotation intensity “weak”) in the rotation direction determined in step S217, and determines the position of the player character in step S219. The position is updated to the position moved by a predetermined distance to the moving position, and the player character is displayed in the updated direction in the updated position in the game field (step S220). Specifically, the update of the direction of the player character in step S220 is, for example, the difference angle between the direction indicated by the vector (PC direction vector) indicating the current direction of the player character and the direction indicated by the movement instruction direction vector. It is realized by calculating and updating the PC direction vector in a direction rotated by a predetermined angle (for example, 1/10 of the difference angle) corresponding to the rotation intensity (weak).

  Thereafter, the control unit 11 determines whether the angle between the movement operation instruction direction (direction indicated by the movement instruction direction vector) by the direction key operation of the keypad 30 and the player character direction (direction indicated by the PC direction vector) is within a predetermined value. It is determined whether or not (step S221). If it is within the predetermined value, the controller 11 ends the correction mode (step S222). On the other hand, if not within the predetermined value, the control unit 11 returns to step S201.

  Steps S216 to S221 described above are repeatedly executed, and then the correction mode is ended in step S222, so that the player can continue to perform the same operation on the direction key of the keypad 30, and the collision with the obstacle is eliminated. After that, the player character can be quickly adjusted so that the moving direction of the player character matches the moving operation instruction direction by the direction key operation of the keypad 30, and the direction of the player character becomes the moving operation instruction direction by the direction key operation of the keypad 30. It will be possible to adjust gradually to match.

  Here, with reference to FIGS. 5 to 9, the movement mode of the player character (PC) in the video game apparatus 100 of the present example will be described. Here, it is assumed that the movement operation instruction direction (direction indicated by the movement instruction direction vector) X by the direction key is continuously the same direction.

  First, as shown in FIG. 5, when the vehicle does not collide with the obstacle Y, the player character moves with the movement operation instruction direction X using the direction keys as the traveling direction (see steps S104 to S107, S115).

  Thereafter, as shown in FIG. 6, when the player character collides with the obstacle Y (Y in step S201), the correction mode is started (step S203), and the inner product value of the movement instruction direction vector and the arrangement direction vector becomes positive or negative. The robot moves in the direction along the obstacle Y while rotating in the rotating direction according to the steps (steps S204 to S214). When the obstacle Y is a wall, the player character moving toward the wall as shown in FIG. 7 changes its direction in the direction along the wall as shown in FIG. become.

  Then, while it is determined that the player character has collided with the obstacle Y (while it is determined as Y in step S201), as shown in FIG. 6, the inner product of the movement instruction direction vector and the arrangement direction vector The operation of moving in the direction along the obstacle Y is continued while rotating in the direction of rotation according to the sign of the value (Y in step S201, Y in S202, N in steps S204 to S214, S215).

Thereafter, when it is determined that the player character has not collided with the obstacle Y (N in Step S201), since it is in the correction mode (Y in Step S216), as shown in FIG. Moving while the player character is rotated so that the direction of the player character approaches gradually (for example, the angle θ between the movement instruction direction vector and the PC direction vector approaches the angle θ ₁ and the angle θ ₂ and 0). The player character moves in the direction indicated by the operation instruction direction X (Y in step S216, S217 to S220, N in S221).

  When the angle between the movement operation instruction direction X and the direction indicating the direction of the player character is within a predetermined value (Y in step S221), the correction mode is terminated (step S222), and the player character instructs the movement operation. It will return to the normal state (non-correction mode state) which moves to the direction X in the movement operation instruction | indication direction X.

  Next, with reference to FIG. 10 and FIG. 11, the movement mode when the player character (PC) in the video game apparatus 100 of this example collides with the wall Za and the pillar Zb which are obstacles will be described. Here, it is assumed that the movement operation instruction direction X by the direction key is continuously the same direction. Although not particularly mentioned in the processing of FIGS. 3 and 4 described above, when a collision with a new obstacle occurs during the correction mode, the correction mode is temporarily ended, and the correction mode is newly set in step S203. Shall be started.

  First, as shown in FIG. 10, when the vehicle does not collide with an obstacle, the player character moves with the movement operation instruction direction X by the direction key as the traveling direction (see steps S104 to S107, S115). Thereafter, when the player character collides with the wall Za (Y in step S201), the correction mode is started (step S203), while rotating in the rotation direction according to the positive / negative of the inner product value of the movement instruction direction vector and the arrangement direction vector. Then, it moves in the direction along the wall Za (steps S204 to S210). While it is determined that the player character has collided with the wall Za (while it is determined as Y in step S201), the player character rotates in the rotation direction according to the sign of the inner product value of the traveling direction vector and the arrangement direction vector. However, the operation of moving in the direction along the wall Za is continued (Y in Step S201, Y in S202, S211 to S214, Steps S209 to S210, N in S215).

  When the player character collides with the column Zb (Y in step S201), as shown in FIG. 11, the column Zb rotates in the rotation direction according to the positive / negative of the inner product value of the movement instruction direction vector and the arrangement direction vector. (Steps S204 to S210). While it is determined that the player character has collided with the pillar Zb (while it is determined as Y in step S201), the player character rotates in the rotation direction according to the sign of the inner product value of the movement instruction direction vector and the arrangement direction vector. However, the operation | movement which moves to the direction along the pillar Zb is continued (Y of step S201, Y of S202, S211-S214, step S209-S210, N of S215).

  Thereafter, when it is determined that the player character has not collided with the pillar Zb (N in Step S201), since it is in the correction mode (Y in Step S216), as shown in FIG. The player character moves in a direction approaching the movement operation instruction direction X while being rotated so that the direction of the player character approaches gradually in the approaching direction (Y in steps S216, S217 to S220, and N in S221). .

  When the angle between the movement operation instruction direction X and the player character's traveling direction is within a predetermined value (Y in step S221), the correction mode is terminated (step S222), and the player character is moved in the movement operation instruction direction X. It will return to the normal state (non correction | amendment mode state) which moves.

  In addition, after returning to the non-correction mode state, it further collides with the wall Za, so that it moves along the wall Za after moving along the column Zb.

  As described above, in the above-described embodiment, the control unit 11 receives the designation of the moving direction of the player character in accordance with the movement instruction operation of the direction key by the player, and determines the position where the player character moves. The correction mode is set to determine whether or not the player character has collided with an obstacle arranged on the game field used in the video game, and to correct the movement position of the player character when it is determined to have collided. If not, the correction mode is set. If it is determined that the collision has occurred when the correction mode is not set, the inner product value of the obstacle direction vector and the movement direction vector is calculated, and the correction mode is set. If it is determined that the vehicle has collided, the obstacle direction vector and the previous direction vector It is configured to calculate an inner product value between Torr). When the control unit 11 determines the position where the player character moves, when the correction mode is not set, the movement of the player character for moving in the moving direction according to the movement instruction operation of the direction key by the player is performed. When the position is determined and it is determined that there is a collision when the correction mode is not set, the movement direction based on the inner product value of the calculated arrangement direction vector and the traveling direction vector is moved in the movement direction along the obstacle. When the movement position of the player character is determined and it is determined that there is a collision when the correction mode is set, the movement direction along the obstacle is the movement direction based on the inner product value of the arrangement direction vector and the previous arrangement direction vector. Determine the movement position of the player character to move to, and collide when the correction mode is set When it is determined not to be configured to determine the movement position of the player character to move in a direction toward the moving direction corresponding to the movement instruction operation of the direction key by the player. With such a configuration, it is possible to smoothly correct the movement position of the player character, and even when an obstacle is placed on the field in the game, the movement instruction operation by the player is strictly performed. The player character can be smoothly moved by a simple operation without requesting, and the player's stress related to the movement operation of the player character can be reduced.

  Further, in the above-described embodiment, when the correction mode is not set, the control unit 11 determines the direction of the player character to be directed in the moving direction in accordance with the movement instruction operation of the direction key by the player, and the collision When it is determined that the player character is directed to rotate in a direction rotated by a predetermined angle in the direction along the obstacle in the rotation direction based on the calculated inner product value, and the correction mode is set When it is determined that there is no collision, the orientation of the player character is determined so as to be directed to a direction rotated by a specific angle in the moving direction in accordance with the direction instruction movement instruction by the player. Even if there are obstacles on the field in the game. Player character with a simple operation without strictly requiring the movement instruction operation can be moved smoothly by, it is possible to reduce the stress of the player involved in the operation of moving the player character.

  In the above-described embodiment, since the control unit 11 displays the player character in the determined moving position, the game screen in which the moving position and direction of the player character are smoothly corrected is displayed. Can be displayed.

  In the above-described embodiment, the control unit 11 monitors whether or not the movement direction according to the movement instruction operation of the direction key by the player is changed, and the movement direction is changed when the correction mode is set. If it is determined that the correction mode has been set, the correction mode setting is canceled, so that the correction mode can be quickly canceled when the direction instruction movement instruction of the player is changed.

  In the above-described embodiment, after the player character is moved to the movement position determined according to the determination that the control unit 11 has not collided when the correction mode is set, the player 11 When it is determined whether the angle between the movement direction corresponding to the movement instruction operation of the direction key and the advance direction of the player character is less than or equal to a predetermined correction mode release value, and when it is determined that the angle is less than or equal to the correction mode release value Since the configuration is such that the setting of the correction mode is canceled, the correction mode can be quickly canceled when the moving direction according to the movement instruction operation of the direction key by the player approaches the moving direction of the player character. Become. Therefore, the player character can be moved smoothly.

  In the above-described embodiment, the control unit 11 calculates the planned movement position based on the current position of the player character and the traveling direction vector, and whether or not the calculated planned movement position is within the obstacle arrangement area. Since it is configured to determine whether or not the player character has collided with the obstacle by confirming the above, it is possible to perform the collision determination by simple arithmetic processing. That is, it is not necessary to measure the distance between the obstacle and the player character, and whether or not to collide is determined by a simple calculation, so that the load of collision determination in the control unit 11 can be suppressed. it can.
