Description

VIDEO GAME APPARATUS, IMAGE DISPLAY METHOD, PROGRAM CONTROL METHOD AND STORAGE MEDIUM}

The present invention relates to a video game apparatus, an image presentation method, a program control method, and a storage medium configured to contend for scoring by a player attacking a target displayed on a display using virtual attack means.

For example, as a so-called video game device installed in an organic facility such as a game center, a shooting-only game in which a target (also referred to as an anime character) displayed on the display is simulated using a virtual attack means such as a laser gun or a missile. There is a device. Such a game apparatus creates a video image so that a plurality of targets move and attack in a predetermined scene. And the player can enjoy the game which scores by operating a player character (main character in game) displayed on a display with a joystick etc. and sequentially attacking the several target displayed on the display.

In addition, such a video game apparatus may attack while simultaneously locking on a plurality of targets approaching while the character manipulated by the player is flying in the space displayed on the display.

When the target displayed on the display is attacked by the character, the target changes into items such as coins and gold bars according to the target's point (life value determined according to the type of target in advance). The character then obtains a plurality of items in the air while flying in the virtual space displayed on the display. The point of the obtained item becomes the player's score so that the stage ends or a virtual attack means based on the scoring can be purchased at a weapons store in the stage. Therefore, the more points the target has attacked by the character, the more powerful the weapon can be purchased.

Also, if you are a boss (enemy character with more points than a normal target) without attacking multiple times, you may not be able to knock over without using a stronger weapon, so it is important to get more items.

The player can roll the character in virtual space to avoid it by moving the joystick in the left or right direction. Therefore, if the target attacks the character, it is possible to roll the character and avoid the attack from the enemy.

In addition, the character is not able to move anywhere in the virtual space displayed on the display, but can move only within a predetermined moving limit range in the vertical direction and the left and right directions, and is limited in the moving range by being attacked by the target or obtaining an item.

In addition, when the character is holding a sword, the target can be changed to an item by obtaining the target by pulling the target with the sword. In this case, depending on the target type, there are targets that can be knocked down with only one attack, and targets that can be knocked down after multiple attacks. Is also different.

However, in the conventional video game apparatus as described above, for example, when the character displayed on the display moves to the moving limit position, only the background or the character no longer moves and it is difficult for the player to know. Thus, when the character reaches the limit of movement, the player may not know it and may not be able to dodge the attack from the enemies or attack the target and may not operate as desired.

In addition, when the player moves the joystick in the left direction or the right direction to roll the character in the virtual space, the background displayed on the display rotates to express the rolling state, but conventionally, the viewpoint is set to the back of the character. Even if it was, there was a sense of discomfort because only the background would roll without the character rolling.

In addition, in the related art, acceleration and deceleration of a character is constant, and even if the throttle lever is operated rapidly or slowly, the maximum speed and minimum speed of the character and the background motion displayed on the display are constant or the maximum speed and the minimum speed cannot be maintained.

In addition, in the past, the number of targets that can be locked on has been determined, and since a plurality of targets are displayed, all the targets cannot be locked on, and some targets can pass through without attacking, causing the player to be dissatisfied. It was.

In addition, conventionally, since an item after attacking a plurality of targets is in each target position, there are times when the movement of a character does not correspond to a distributed item and has to pass through without obtaining an item of a target that has been knocked down. It is preferable to place the target side by side up, down, left, and right with respect to the screen in order to lock on (it is easy to lock on) .However, after changing to an item, after changing to an item, This is because it is difficult to obtain all the items while the player character is running in the length direction to the inside if they are displayed side by side.

In addition, when a character fights with a sword in the related art, when a target is displayed on the front side when the back of the target is cut with a sword, it is not possible to know whether the bent position by the sword is not displayed on the display and whether the target is cut. . In addition, conventionally, when a character performs an operation of cutting a target using a sword, the character's movement is often followed while turning the camera position (viewpoint) displayed on the display to the left and right, but the character and the target are viewed from the side. Since Benza is not displayed by the sword, it was not known whether the target was cut.

It is therefore an object of the present invention to provide a video game apparatus, an image presentation method, a program control method, and a storage medium which solve the above problems.

As the character 54 moves in the horizontal direction or the vertical direction, the lock on site 58 moves to a position overlapping the target 49. When the lock on site 58 coincides with the target 49 in this manner, the target 49 is displayed in a state surrounded by a triangular sign 50.

(1) Example of display when the character reaches the limit position for movement

4 illustrates an example in which the character designated by the player is displayed on the display unit 13 in the air. (A) shows a state in which the character is moving in the right direction. (B) shows how the display frame of the display unit 13 has moved in the same direction in accordance with the movement of the character. (C) shows the state where the character has reached the limit of movement.

As shown in FIG. 4A, the display unit 13 displays the character 45 designated by the player in the air, and the background 46 in the advancing direction of the character 45 shows the moving speed of the character 45. It moves in its direction at a relative speed of. Accordingly, in the image displayed on the display unit 13, the background 46 moves so that the character 45 is always displayed in the center of the screen, and the background 46 moves at the speed corresponding to the operation position of the throttle lever 16. 45 to move toward. Accordingly, the player can see as if the character 45 is flying in the air.

In the present embodiment, the display frame Y of the display unit 13 can move up, down, left and right in the displayable range X of the virtual space formed by computer graphics in accordance with the operation direction of the operation lever 15. For the displayable range X, the display frame Y of the display unit 13 is very small. The display frame Y of the display unit 13 moves within the displayable range X to follow the movement of the character 45 moving in accordance with the operation direction of the operation lever 15 so that the character 45 is displayed at the center of the screen. Doing.

If the player tilts the operation lever 15 in the right direction, the character 45 moves from the center of the display frame Y to the right direction.

As shown in FIG. 4B, when the character 45 moves to the right and moves to the right end of the display frame Y, the display frame Y of the display unit 13 also moves in the same direction to follow the movement of the character 45. Move.

In addition, when the player tilts the control lever 15 to the right, the character 45 attempts to move to the right, but, for example, there is a cliff or the like and reaches a moving limit position that cannot be moved to the right. When the right end of the display frame Y of the unit 13 reaches the movement limit position of the displayable range X, as shown in Fig. 4C, the entire image displayed on the display unit 13 is moved in the left and right directions or up and down. It vibrates in a direction to inform the player that it cannot move in the right direction. When the character 45 moves to the left direction, or when the character 45 no longer moves to the left direction, or when the left end of the display frame Y of the display unit 13 reaches the operating limit position of the displayable range X It vibrates the whole left and right to inform the player that it cannot move left.

When the character 45 moves upward or downward, it is no longer possible to move upward or downward, or the display frame Y of the display unit 13 has reached the operating limit position of the displayable range X. In this case, the whole image is vibrated in the up and down direction to inform the player that it cannot move in the up and down direction.

(2) Rolling motion display example when the viewpoint is the objective position

5 shows a display example of an image representing a rolling operation when the viewpoint of the image displayed on the display unit 13 is an objective position with respect to the player character. (A) shows the state before rolling, (B) shows the state in which the character 45 started rolling, (C) shows the state in which the character 45 reversely rotated, and (D) shows the character 45 270 ° indicates a rolled state.

As shown in Fig. 5A, the character 45 is flying in the form of a rocket on its back and is displayed in the center of the screen of the display unit 13 in a forward-facing position. Here, if the player sharply tilts the operation lever 15 to the right within a predetermined time, the background displayed on the display unit 13 as shown in Fig. 5 (B) normally tilts the operation lever 15 to the right. As shown, only the character 45 starts rolling in the right direction without moving in the right direction.

In this state, the player keeps the operation lever 15 inclined in the right direction so that the character 45 is rotated by 180 ° as shown in Fig. 5C and as shown in Fig. 5D. As shown in Fig. 5 (A), it is returned to the state shown in FIG. The character 45 repeats the above rolling operation until the operation lever 15 returns to the vertical neutral position.

In this way, when the operation lever 15 is inclined rapidly in the right direction within a predetermined time, the character 45 may roll clockwise to avoid an attack from the enemy. When the player tilts the operation lever 15 sharply to the left, the character 45 can roll in the counterclockwise direction to avoid an attack from the enemy.

(3) Example of the rolling operation display when the viewpoint is in the subjective position

6 shows an example of an image display representing a rolling operation when the image viewpoint displayed on the display unit 13 is a subjective position, (A) shows the state before rolling, and (B) shows the rolling of the display image. (C) shows a state in which the display image is reversely rotated, and (D) shows a state in which the display image is rolled by 270 degrees.

As shown in FIG. 6A, when the viewpoint is a subjective position, the virtual camera position of the image displayed on the display unit 13 is equal to the eye height position of the character 45. Therefore, when the viewpoint is the subjective position, the display unit 13 does not display the character 45 but only the background 46 in the advancing direction. In this case, since the character 45 is not displayed in the center of the screen, it is easy to confirm the existence of the target.

If the player inclines the operation lever 15 to the right within a predetermined time, as shown in Fig. 6B, the display image 47 of the display unit 13 normally moves the operation lever 15 to the right direction. Instead of moving to the right as if tilted, the whole starts rolling to the right.

In this state, the display image 47 of the display unit 13 is rotated by 180 ° as shown in Fig. 6C, and is rotated by 270 ° as shown in Fig. 6D. After that, it returns to the horizontal state shown in FIG. 6 (A). The character 45 may repeat the above rolling operation until the operation lever 15 returns to the vertical neutral position. The center of the rolling motion in this case is the eye height position of the character 45.

In this way, when the operation lever 15 is inclined rapidly in the right direction within a predetermined time, the display image 47 of the display unit 13 rolls clockwise. In addition, when the player tilts the operation lever 15 sharply to the left, the display image 47 of the display unit 13 rolls in the counterclockwise direction.

(4) Display example of lock on operation

7 is a display example showing an operation when the character locks the target, (A) shows the operation before the target is locked on, (B) shows the operation when the lock is on, and (C) the lock. It shows the action when attacking the on target, and (D) shows the action of the item under attack.

As shown in FIG. 7A, the display unit 13 displays a character 45, a lock on meter 48, and a plurality of targets 49. The plurality of targets 49 are expanded in the advancing direction of the character 45 and fly toward the character 45. Therefore, the character 45 can attack after locking the target 54 returned to the lock-on site among the several target 49 approaching.

The lock on meter 48 is a level meter indicating the life power (physical strength) of the character 45, and as described later, the lock on number of the target is determined according to this life power value. Therefore, if the number of targets 49 exceeds the life power value, all targets 49 cannot be locked on. In addition, depending on the target type, the lock cannot be locked when the life power value is larger than that of the character 45.

As shown in Fig. 7B, when the player presses the firing button 17 of the control lever 15, the target 49 entering the lock on site changes to a triangular sign 50 and automatically locks as an attack target. It is on. In the next moment, when the player releases his finger from the firing button 17 of the control lever 15, the player simultaneously attacks the locked targets 49 at the same time. As a result, each target 49 that is attacked changes to an item 51 in the shape of a gold coin, as shown in FIG.

The item 51 moves so that it may gather in the vicinity of the path 52 (indicated by a dashed line) of the character 45 as shown in FIG. 7D. Thus, each item 51 can be obtained without changing the course of the character 45. Therefore, the character 45 flying at high speed can easily obtain all the items 51 without missing the item 51. When the item 51 is obtained, the level value of the lock on meter 48 is increased by the score of the item 51.

(5) Example of display when using a sword as an attack means

Fig. 8 is a display example showing the action when the character cuts the target using the sword as an attack means, (A) shows the action before the target is cut, and (B) shows the action when the character is cut with the sword. , (C) shows the position of the benzine of the target in the ben trace with a sword, (D) shows a state where the flash is synthesized in the benzine of the target.

As shown in FIG. 8 (A), the character 45 is in a state where the sword 53 is held on the right hand and is trying to attack the target 54. At the next moment, the character 45 cuts the target 54 with the sword 53, as shown in Fig. 8B.

As shown in FIG. 8 (C), the coordinate position of the polygon plane, which is the bent seat 55 of the target 54, is obtained from the movement trajectory of the tip of the sword 53. Next, as shown in FIG. 8 (D), the glare 56 is synthesized in the bezel 55 of the target 54. Since the glare 56 is represented so that light is emitted from the perimeter of the bezel 55, the glare 56 is formed at the bezel 55 of the target 54 regardless of the virtual camera position in any direction with respect to the target 54. The appearance of this radiation is displayed. Therefore, the player can confirm that the target 54 is cut by the flash 51 radiated from the perimeter of the seat 55 even when the target 54 is cut to the sword 53 in any direction of the front, the side, and the rear. have.

Here, the control processing executed by the CPU 25 of the video game apparatus 11 will be described.

9 is a main flowchart of control processing executed by the CPU 25 of the video game apparatus 11. FIG. 10 is a main flowchart of control processing executed by the CPU 25 following the control processing shown in FIG. 9.

As shown in FIG. 9, the CPU 25 first displays an advertisement-only image on the display unit 13 in step S11 (hereinafter, "step" is omitted). As the advertisement-only image, for example, an attack scene as shown in Figs. 7A to 7D is displayed on the display unit 13 as a demonstration.

In S12, it is checked whether the coin is inserted into the coin inlet 41. If the coin detection switch (not shown) provided in the coin inlet 41 is on, the process advances to S13 and displays on the display unit a character selection screen for selecting a character to participate in the game. In S14, when the player presses the select button 43 and designates a character participating in the game among the characters displayed on the character selection screen, the process advances to S15 to determine whether the start button 42 has been operated on.

When the start button 42 is turned on in S15, for example, an image as shown in Fig. 4A described above is displayed on the display unit 13 as a start screen. If it is detected in S17 that the throttle lever 16 has been operated on the acceleration side, the flow advances to S18 to read the operation position (speed value) of the throttle lever 16.

Subsequently, in S19, the moving speed of the character 45 (actually the relative speed of the background 46) is calculated from the operation position detection signal of the throttle lever 16, and the display speed of the image displayed on the display unit 13 is throttled. The speed is adjusted at a speed corresponding to the operation position of the lever 16.

In S20, it is checked whether the operation lever 15 has been operated. When the operation lever 15 is operated in S20, the flow advances to S21 and the operation direction of the operation lever 15 and the operation speed of the operation lever 15 are read. Subsequently, in S22, the character 45 is moved in the direction corresponding to the operation direction of the operation lever 15 and the operation speed of the operation lever 15.

In S23, it is checked whether the target 49 is locked on. When the target 49 is not locked on at S23, the process returns to S18 described above and the processes from S18 to S23 are repeated. When the target 49 enters the lock on site and is locked on in S23 (see Fig. 7B), it proceeds to S24 in Fig. 10 and checks whether an attack is performed.

When attacking the target 49 locked on at S24 (see FIG. 7C), the flow advances to S25 to obtain an item 51 of the target 49 (see FIG. 7D). Subsequently, in S26, the points of the obtained item 51 are added by scoring. In S27, it is checked whether or not a counterattack from the target 49 has been received. If no counterattack from the target 49 is received in S27, the process returns to S23 and the process after S23 is executed.

However, when a counterattack is received from the target 49 in S27, the process proceeds to S28, and the damage received by the character 45 is determined, and the number of damages is counted in S29. In S30, it is checked whether the count value of the damage count has reached the preset setting value n. When the count value of the number of damages does not reach the set value n in S30, the flow advances to S31 to check whether or not the stage is finished.

When the stage viewed in S31 has not ended, the process returns to S18 and the process subsequent to S18 is executed again. However, when the stage viewed in S27 is finished, the flow advances to S32 to move to the next stage. Then, the process returns to S18 and the process after S18 is executed again.

When the count value of the number of damages reaches the set value n in S30, the process proceeds to S37 and the game is over.

When not attacking the target 49 locked on at S24, the process proceeds to S33 and checks whether a counterattack from the target 49 has been received. If no counterattack from the target 49 is received in S33, the process returns to S18 and the process after S18 is executed. Accordingly, the plurality of targets 49 can be locked on.

However, in S33, when receiving a counterattack from the target 49, it advances to S34 and the damage which the character 45 received is determined, and the number of damages is counted in S35. In S36, it is checked whether the count value of the damage count reaches the preset setting value n. When the count value of the number of damages in S36 has not reached the set value n, the process returns to S18 and executes the process after S18 again. When the count value of the damage count reaches the set value n in S36, the process proceeds to S37 to cause a game over.

In this manner, the CPU 25 sequentially locks on and attacks the target 49 while moving the character 49 by the operation of the operation lever 15, the throttle lever 16, and the firing button 17. ), And execute the operation of the shooting game to obtain a higher score.

In addition, the CPU 25 generates and outputs 60 frames of image data for one second through the VDP 33. When each frame is changed, interrupt processing is appropriately executed.

Here, the interrupt processing executed by the CPU 25 will be described.

11 is a flowchart for explaining interrupt processing of throttle control (acceleration control means) executed by the CPU 25.

As shown in FIG. 11, the CPU 25 checks whether the operation position of the throttle lever 16 changes to the acceleration side in S41. When the operating position of the throttle lever 16 changes to the acceleration side in S41, the flow advances to S42 to confirm whether the throttle lever 16 has been operated at the first acceleration position. When the throttle lever 16 is operated in the first acceleration position in S42, the flow advances to S43, and the movement speed of the character 45 is accelerated to the normal speed with the normal acceleration.

When the throttle lever 16 has not been operated in the first acceleration position in S42, the flow advances to S44 and confirms whether the throttle lever 16 has been operated in the second acceleration position. When the throttle lever 16 is operated in the second acceleration position in S44, the flow advances to S45, and the movement speed of the character 45 is accelerated to the maximum speed with normal acceleration.

When the throttle lever 16 has not been operated to the second acceleration position in S44, the flow advances to S46 to confirm whether the throttle lever 16 has been rapidly operated to a position exceeding the second acceleration position. When the throttle lever 16 is rapidly operated at an acceleration position equal to or higher than the second acceleration position in S46, the flow advances to S47, and the movement speed of the character 45 is normally accelerated to the maximum speed with twice the acceleration. In this case, for example, as shown in FIG. 4A, the background 46 moves on the highway to its own side, and the character 45 also moves toward the direction of progress so that the movement to reach the maximum speed at a normal double acceleration can be expressed.

Therefore, the player can move the character 45 at full speed in a short time by rapidly sliding the throttle lever 16 to the acceleration side when the player fights by increasing the movement performance of the character 45 and the game is more advanced. Each stage of can be cleared.

When the operating position of the throttle lever 16 does not change on the acceleration side in S41, the flow advances to S48, and it is checked whether the operating position of the throttle lever 16 has changed on the deceleration side in S48. When the operating position of the throttle lever 16 changes to the deceleration side in S48, the flow advances to S49 to check whether the throttle lever 16 has been operated to the first deceleration position. When the throttle lever 16 is operated to the first deceleration position in S49, the flow advances to S50 to decelerate the movement speed of the character 45 at a normal deceleration rate.

When the throttle lever 16 has not been operated to the first deceleration position in S49, the flow advances to S51 to confirm whether the throttle lever 16 has been operated to the second deceleration position. When the throttle lever 16 is operated to the second deceleration position in S51, the flow advances to S52, and the movement speed of the character 45 is decelerated at twice the normal deceleration.

When the throttle lever 16 has not been operated to the second deceleration position in S52, the flow advances to S53 to confirm whether the throttle lever 16 has been rapidly operated to a position exceeding the second deceleration position. When the throttle lever 16 is rapidly operated to the deceleration position above the second deceleration position in S53, the flow advances to S54, where the movement speed of the character 45 is decelerated at a normal double deceleration and the character 45 is stopped. In this case, for example, as shown in FIG. 4A, the movement speed of the background 46 is decelerated, and at the same time, the character 45 also moves in the opposite direction to the traveling direction, thereby decelerating the normal double deceleration.

In addition, when the player operates the throttle lever 16 to the shortest position within a predetermined time, the speed may be increased further than the maximum speed by normal operation. The same applies to the deceleration speed.

12 is a flowchart for explaining the interrupt processing of the movement limit control executed by the CPU 25.

As shown in FIG. 12, when the CPU 25 detects the displacement of the operation lever 15 in S60, the CPU 25 advances to S61 and moves the character 45 in the operation direction of the operation lever 15. For example, when the player tilts the operation lever 15 in the right direction, the character 45 moves from the center of the display frame Y to the right direction (see Fig. 4A).

Next, in S62, the display frame Y of the display unit 13 is moved in the moving direction of the character 45 so that the character 45 is displayed at the center of the display unit 13. For example, when the character 45 moves in the right direction and moves to the right end of the display frame Y, the display frame Y of the display unit 13 also moves in the same direction to follow the movement of the character 45 (Fig. 4 (B)). See).

In S63, it is checked whether the movement position of the character 45 reaches the movement limit position of the virtual space by computer graphics. When the character 45 has not reached the moving limit position at S63, the process proceeds to S64 and checks whether the display frame Y of the display unit 13 has reached the operating limit position of the displayable range X. When the display frame Y of the display unit 13 does not reach the operating limit position of the displayable range X in S64, this interruption process ends.

However, when the character 45 reaches the movement limit position in S63, or when the display frame Y of the display unit 13 reaches the operating limit position in the displayable range X in S64, the process proceeds to S65 and shown in Fig. 4C. As shown, the entire image displayed on the display unit 13 is vibrated in left and right directions to inform the player that the image cannot be moved in the right direction (image display means).

In addition, when the display frame Y of the character 45 or the display unit 13 reaches the movement limit position and cannot move upward or downward, or the display frame Y of the display unit 13 is the operating limit position of the displayable range X. When is reached, the whole image is vibrated up and down, and the player is notified that the image cannot be moved up and down.

Accordingly, the player can recognize that the character 45 can no longer move while concentrating on the game, and can prevent the character 45 from making unnecessary movements and improve the scoring.

13 is a flowchart for explaining interrupt processing of rolling control to be executed by the CPU 25.

As shown in FIG. 13, the CPU 25 confirms whether the operation lever 15 is suddenly rolled left or right in S70 (rolling operation detecting means). If the rolling operation has been performed in S70, the flow advances to S71 to confirm the viewpoint setting position of the image currently displayed on the display unit 13.

In S72, it is checked whether or not the viewpoint setting position is at the objective position (the viewpoint is behind the character 45) (viewpoint determination means). When the viewpoint is at the objective position in S72, the flow advances to S73, and only the character 45 is rotated in the operation direction of the operation lever 15 (see Figs. 5A to 5D, display control means). When the character 45 makes one turn in S74, this interrupt processing ends.

When the viewpoint is not at the objective position in S72, the process advances to S75 and determines that the viewpoint setting position is at the subjective position (the viewpoint is at the eye height of the character 45). In S76, the entire display image displayed on the display unit 13 is rotated in the operation direction of the operation lever 15 (see Figs. 6A to 6D, display control means). When the entire displayed image is rotated once in S77, this interrupt processing ends.

In this way, when the operation lever 15 is suddenly rolled left or right, a rolling operation corresponding to the viewpoint setting position of the image displayed on the display unit 13 can be performed. Thus, for example, the problem of rotating the entire display image of the display unit 13 can be solved while the viewpoint setting position is at the objective position as in the prior art.

14 is a flowchart for explaining the interrupt processing of the lock-on control to be executed by the CPU 25.

As shown in Fig. 14, when the position of the target 49 is detected in S80, the CPU 25 checks whether the target 49 has entered the lock-on site 58 (see Fig. 3) in S81. If the target 49 enters the lock on site at S81, the process proceeds to S82 where the level (life bar watch) of the lock on meter 48 (see FIG. 7A) is larger than the physical value (point value) of the target 49. Check if it is big.

When the level (life bar watch) of the lock on meter 48 is greater than the stamina value (point value) of the target 49 in S82, the process proceeds to S84, the corresponding target 49 is locked on, and the target 49 is a triangular symbol 50. ) (See Fig. 7 (B), lock on control means). Subsequently, in S85, the stamina value (point value) of the target 49 locked on at the level of the lock on meter 48 is subtracted (lock on subtraction means).

In S86, it is confirmed that the level of the lock-on meter 48 from which the stamina value (point value) of the target 49 is subtracted is zero or more. When the level of the lock on meter 48 is 0 or more, the process returns to S80, and the lock on process of the other target 49 is repeated. Accordingly, the number of targets 49 corresponding to the level of the lock on meter 48 can be locked on, and a simultaneous attack on the plurality of targets 49 can be performed.

However, when the level of the lock on meter 48 reaches 0 in S86, lock on is not possible, and this lock on control ends.

In addition, when the level (life bar watch) of the lock on meter 48 is smaller than the stamina value (point value) of the target 49 in S86, lock on is impossible and this lock on control is complete | finished.

As described above, since the plurality of targets 49 that match the level (life watch) of the lock on meter 48 can be locked on, the attack power is more suitable for the player's operation level than when the lock on number is fixed. You can increase the sex.

In addition, when a plurality of targets 49 having different life-watches appear on the screen of the display unit 13, the player can preferentially select and lock on the target 49.

15 is a flowchart for explaining interrupt processing of item control to be executed by the CPU 25.

As shown in Fig. 15, when the CPU 25 attacks the target 49 in S90, the CPU 25 advances to S91 and changes the attacked target 49 into an item 51 such as a gold coin (see Fig. 6C). , Item conversion means). In S92, the item 51 is moved to approach the course 52 of the character 45 (see FIG. 6 (D), item moving means). As a result, the character 45 moving at high speed can obtain all of the items 51 of the target 49 attacked without changing the course.

As shown in Figs. 16A to 16D, regardless of the path 52 of the character 45, the item 51 moves in the longitudinal direction up and down and to the inside of the screen and to the inside of the screen. It may be arranged in the longitudinal direction.

In S93, it is checked whether the character 45 moves and the item 51 is obtained. When the character 45 moving in S93 obtains the item 51, the process proceeds to S94 and the point of the item 51 is added to the game score. Subsequently, in S95, the point of the item 51 is added to the lock on meter 48. This completes this item control.

Thus, by obtaining more items 51, the level of the lock on meter 48 is increased and it is possible to lock on the stronger target 49. Therefore, the higher level players can play more games because they can push stronger targets and go to higher stages.

If the item 51 is not obtained in S93, the item control ends.

FIG. 17 is a flowchart for explaining interrupt processing of Venn control of a sword to be executed by the CPU 25.

As shown in FIG. 17, when the character 45 attacks the target 54 with the sword 53 in S100 (see FIG. 8 (A) (B)), the CPU 25 goes to S101 and displays an image. The motion trajectory of the polygon coordinates of the tip of the sword 53 to be generated each time is read. The motion trajectory when cut with the sword is the coordinate before the operation of the tip of the sword 53 and the front of the sword and the coordinate when the tip of the sword 53 intersects the target 54 and the tip and the hand of the sword 53. Can be obtained from the coordinates after the preceding operation.

In S102, the coordinates at which the target 54 is displayed are read.

In S103, it is checked whether the motion trajectory of the tip of the sword 53 intersects the coordinate of the target 54. When the trajectory of the sword 53 intersects with the coordinate of the target 54 in S103, the coordinate position of the polygon surface, which is the benthic position 55 of the target 54 to cross the extension line of the trajectory of the sword 53, is crossed. And Venn 55 is displayed on the polygon of the target 54 (see Fig. 8 (C), Venzine display means). The bend 55 of the target 54 can be expressed as a polygon surface in the unit normal vector obtained from the motion trajectory of the tip of the sword 53.

Subsequently, the polygon of the flash 56 previously prepared is attached to the bezel 55 of the target 54 in S105 (see FIG. 8D). Accordingly, since the bezel 55 of the target 54 cut by the sword 53 and the polygon of the flash 56 cross each other, the glare 56 is radiated from the entire circumference of the bezel 55. In addition, the player can confirm in the image that the target 54 has been damaged no matter in which direction the target 54 is attacked using the sword 53.

Therefore, when the character 45 swings the sword 53 to attack the target 54, even when the camera position (viewpoint position) is moving, the telephone pole of the bent seat 55 along the extension line of the trajectory of the sword 53 is moved. Since the glare 56 is fired at all, it is possible to visually recognize that the target 54 is damaged regardless of the camera position (viewpoint position). Therefore, even in a scene in which the character 45 and the target 54 are severely moved from each other, the moment when the target 54 is cut by the sword 53 can be expressed, and the force when the sword 53 is used is displayed more clearly. It becomes possible.
