Description

  The present invention relates to an image generation system, a program, and an information storage medium.

  Conventionally, an image generation system (game system) that generates an image that can be seen from a virtual camera (a given viewpoint) in an object space that is a virtual three-dimensional space is known. Popular. Taking an image generation system capable of enjoying a fighting game as an example, a player operates his / her character (model object) using a game controller (operation means), and plays against an enemy character operated by an opponent player or a computer. Enjoy the game.

Now, in the past three-dimensional fighting game, although it is a three-dimensional game, the element as an extension of what is called a two-dimensional fighting game remained deeply. For example, when deciding which character's attack won in the attack and defense between the player character and the enemy character, the superiority or inferiority of the attack and defense has been determined by the method that has been popular in the two-dimensional fighting game. For this reason, the characteristic of the three-dimensional fighting game that the character can freely move around in the object space cannot be utilized, and a suitable operation environment that is easy for the player to understand cannot be provided.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an image generation system, a program, and an information storage medium that can provide a suitable operation environment that is easy for a player to understand. It is in.

  In order to solve the above problems, the present invention is an image generation system for generating an image, and a motion control means for controlling the motion of each character of a plurality of characters based on an operation input of each player of the plurality of players. If one character performs the first action and the other character performs the second action, the one character that performed the first action is set to be more advantageous than the other character. When one character performs the second action and the other character performs the third action, the one character that has performed the second action is set to be more advantageous than the other character, If one character performs the third action and the other character performs the first action, the one character that has performed the third action is set to be more advantageous than the other character. An image setting means, a parameter changing means for changing attribute parameters relating to the attack of the first, second, and third actions, and an image that can be seen from a virtual camera in an object space in which a plurality of objects including characters are arranged. And an image generation means. A program according to the present invention causes a computer to function as the above means. An information storage medium according to the present invention is a computer-readable information storage medium, and stores (records) a program for causing a computer to function as the above means.

  According to the present invention, the first action (movement, motion) of the character is set to be advantageous for the second action, and the second action is advantageous for the third action. And the third action is set to be advantageous to the first action. Therefore, the player who operates the character can immediately understand which triangle action will be superior to the opponent by simply thinking about this triangular relationship in mind, and it is easy for the player to understand. Can provide a simple operating environment.

  In the image generation system, the program, and the information storage medium according to the present invention, the parameter changing unit may change the attribute parameter related to the attack / defense of one of the first, second, and third operations. It is characterized in that the attribute parameter relating to the attack and defense of the operation is changed.

  In the image generation system, the program, and the information storage medium according to the present invention, the attribute parameter is a parameter of a hit area size of an attack action that is the first action, the second action, and the third action of one character. The parameter changing means changes the size of the hit area for another operation when the size of the hit area for one of the first, second, and third operations is changed. It is characterized by.

  In the image generation system, the program, and the information storage medium according to the present invention, the attribute parameter is a parameter of an effective attack period in which the attack action that is the first, second, and third action of one character is effective. And the parameter changing means changes the length of the attack effective period for the other operation when the length of the attack effective period for one of the first, second, and third operations is changed. It is characterized by changing.

  In the image generation system, the program, and the information storage medium according to the present invention, the attribute parameter is obtained when the attack action that is the first, second, or third action of one character hits the other character. The parameter change means changes the length of the inoperable period for one of the first, second and third actions. Further, the length of the inoperable period for other operations is changed.

  In the image generation system, the program, and the information storage medium according to the present invention, the attribute parameter sets the direction of one character performing the attacking motion as the first, second, and third motions to the direction of the other character. A parameter of the axis follow-up correction amount to be directed, and the parameter changing means changes the axis for another operation when the shaft follow-up correction amount for one of the first, second, and third operations is changed. The tracking correction amount is changed.

  In the image generation system, the program, and the information storage medium according to the present invention, the first action of the character is a vertical attribute attack in which the attack direction is substantially along the vertical plane, and the second action of the character is: If the attack direction is a horizontal attribute attack that is almost along the horizontal plane, and one character performs a vertical attribute attack and the other character performs a horizontal attribute attack, It is characterized in that it is set more advantageously than the other character.

  In this way, it is possible to prevent the player from frequently using horizontal attribute attacks that generally have a high probability of winning, and to prevent the game from becoming monotonous.

  The image generation system, the program, and the information storage medium according to the present invention, when the first hit area of the vertical attribute attack of one character and the second hit area of the horizontal attribute attack of the other character are hit, It is characterized in that the other character is caused to perform an action indicating an attack, or the other character is set in an inoperable state for a given period.

  In this way, due to the vertical attribute attack of one character, the other character performs an action indicating that it has been attacked or becomes inoperable only for a given period, and advantageously sets one character. Processing can be realized.

  In the image generation system, program, and information storage medium according to the present invention, the first pseudo hit has a larger area than the hit area specified by the attack trajectory of the vertical attribute attack of one character. The second hit area is a second pseudo hit area having a larger area than the hit area specified by the attack trajectory of the other character's horizontal attribute attack.

  In this way, it is possible to express an image in which each attack frequently hits when the vertical attribute attack and the horizontal attribute attack occur simultaneously, and the effect of rendering the generated image can be enhanced.

  In the image generation system, the program, and the information storage medium according to the present invention, the second action of the character is a lateral attribute attack in which the attack direction is substantially along the horizontal plane, and the third action of the character is an object It is a movement action in which a character moves in an arbitrary direction in space, and when one character makes a horizontal attribute attack and the other character makes a movement action, one character that made the horizontal attribute attack It is characterized in that it is set more advantageously than the other character.

  In this way, it can be expressed that the lateral attribute attack is strong against the movement operation, and a realistic image that the player does not feel unnatural can be generated.

  In addition, the image generation system, the program, and the information storage medium according to the present invention can change the orientation of one character of the other character when the other character performs a moving action when the one character performs a lateral attribute attack. The correction amount directed in the direction is set to a value larger than that of other attack actions.

  In this way, the direction of one character can be easily directed to the direction of the other character, and a process for advantageously setting one character can be realized.

  In the image generation system, the program, and the information storage medium according to the present invention, the third movement of the character is a movement movement in which the character moves in an arbitrary direction in the object space, and the first movement of the character is If the attacking direction is a vertical attribute attack that is substantially along the vertical plane, and one character performs a moving action, the other character performs a vertical attribute attack. It is characterized in that it is set more advantageously than the other character.

  In this way, it can be expressed that the moving operation is strong against the vertical attribute attack, and a realistic image that the player does not feel unnatural can be generated.

  The image generation system, the program, and the information storage medium according to the present invention may be configured such that when one character performs a moving motion and the other character performs a vertical attribute attack, the other character has a vertical attribute attack. Even when it is determined that the character has been hit, the hit determination is canceled.

  In this way, even when a hit determination that a vertical attribute attack of the other character hits one character is made, this hit determination is canceled, and the process of setting one character advantageously Can be realized.

  In addition, the image generation system, the program, and the information storage medium according to the present invention provide a given angle including the direction of the other character even when it is determined that the vertical attribute attack of the other character hits one character. When one character is located outside the range, the hit determination is canceled.

  In this way, although one character is positioned in the front direction of the other character, the hit of the vertical attribute attack of the other character is canceled and an unnatural image is generated. Can be prevented.

  The image generation system, the program, and the information storage medium according to the present invention are characterized in that when the hit determination is canceled, the position or direction of the virtual camera is changed so that the hit location is not visible from the virtual camera. To do.

  In this way, it is possible to prevent the player from seeing a contradictory image in which the vertical attribute attack of the other character appears to be hit despite the hit determination being canceled.

  In addition, the image generation system, the program, and the information storage medium according to the present invention, when the hit determination is canceled, the vertical attribute attack of the other character does not appear to hit one character when the replay image is generated. A corrected image that is visible is generated.

  In this way, it is possible to prevent a contradictory image in which the vertical attribute attack of the other character appears to be hit even though the hit determination is canceled, and is generated as a replay image.

  Further, the image generation system, the program, and the information storage medium according to the present invention, when the attribute parameter related to the offense / defense of any one of the first, second, and third operations is changed, It is characterized in that attribute parameters related to attack and defense are also changed in conjunction.

  In this way, it is possible to prevent a situation in which the balance between superiority and inferiority of the attack and defense is lost, and various game balance adjustments can be realized while maintaining the balance of superiority and inferiority in the attack and defense.

  Further, the present invention is an image generation system for generating an image, wherein the motion control means for controlling the motion of each character of the plurality of characters based on the operation input of each player of the plurality of players, When a vertical attribute attack with the attack direction approximately along the vertical plane is performed, if the other character performs a horizontal attribute attack with the attack direction approximately along the horizontal plane, It includes means for advantageously setting a character compared to the other character, and means for generating an image visible from a virtual camera in an object space in which a plurality of objects including the character are arranged. A program according to the present invention causes a computer to function as the above means. An information storage medium according to the present invention is a computer-readable information storage medium, and stores (records) a program for causing a computer to function as the above means.

  According to the present invention, the vertical attribute attack of the character is set to be advantageous over the horizontal attribute attack. As a result, it is possible to prevent the player from frequently using horizontal attribute attacks that generally have a high probability of winning, and to prevent the game from becoming monotonous.

  Hereinafter, the present embodiment will be described with reference to the drawings.

  In addition, this embodiment demonstrated below does not limit the content of this invention described in the claim at all. In addition, all the configurations described in the present embodiment are not necessarily essential configuration requirements of the present invention.

1. Configuration FIG. 1 shows an example of a functional block diagram of an image generation system (game system) of the present embodiment. In this figure, the present embodiment only needs to include at least the processing unit 100 (or include the processing unit 100 and the storage unit 170), and the other blocks can be optional components.

  The operation unit 160 is for a player to input operation data, and the function can be realized by hardware such as a lever, a button, a microphone, a sensor, or a housing.

  The storage unit 170 serves as a work area such as the processing unit 100 or the communication unit 196, and its function can be realized by hardware such as a RAM.

  The information storage medium 180 (computer-readable medium) stores programs, data, and the like, and functions as an optical disk (CD, DVD), magneto-optical disk (MO), magnetic disk, hard disk, and magnetic tape. Alternatively, it can be realized by hardware such as a memory (ROM). The processing unit 100 performs various processes of the present invention (this embodiment) based on a program (data) stored in the information storage medium 180. That is, the information storage medium 180 stores a program for causing a computer to function as each means (particularly a block included in the processing unit 100) of the present invention (this embodiment) (a program for causing the computer to realize each means). (Recorded and stored).

  Part or all of the information stored in the information storage medium 180 is transferred to the storage unit 170 when the system is powered on. The information storage medium 180 can include a program for performing the processing of the present invention, image data, sound data, display object shape data, and the like.

  The display unit 190 outputs an image generated according to the present embodiment, and the function thereof can be realized by hardware such as a CRT, LCD, or HMD (head mounted display).

  The sound output unit 192 outputs the sound generated by the present embodiment, and its function can be realized by hardware such as a speaker.

  The portable information storage device 194 stores player personal data, game save data, and the like. As the portable information storage device 194, a memory card, a portable game device, and the like can be considered.

  The communication unit 196 performs various controls for communicating with the outside (for example, a host device or other image generation system), and functions as hardware such as various processors or a communication ASIC. Or by a program.

  A program (data) for causing a computer to function as each unit of the present invention (this embodiment) is distributed from the information storage medium of the host device (server) to the information storage medium 180 via the network and the communication unit 196. You may do it. Use of such an information storage medium of the host device (server) is also included in the scope of the present invention.

  The processing unit 100 (processor) performs various processes such as a game process, an image generation process, and a sound generation process based on operation data from the operation unit 160, a program, and the like. In this case, the processing unit 100 performs various processes using the main storage unit 172 in the storage unit 170 as a work area.

  Here, the processing performed by the processing unit 100 includes coin (price) acceptance processing, various mode setting processing, game progress processing, selection screen setting processing, and the position and rotation angle of an object (one or a plurality of primitives). Processing for obtaining (rotation angle around X, Y or Z axis), processing for moving an object (motion processing), processing for obtaining a viewpoint position (virtual camera position) and line of sight angle (virtual camera rotation angle), map object Consider processing such as placing objects in the object space, hit check processing, computing game results (results, results), processing for multiple players to play in a common game space, or game over processing, etc. Can do.

  The processing unit 100 includes an operation control unit 110, an operation setting unit 116, a hit check unit 118, an image generation unit 120, and a sound generation unit 130. Note that the processing unit 100 need not include all these functional blocks.

  Here, the motion control unit 110 performs processing for controlling the motion (movement, motion) of the character operated by the player, and includes a movement processing unit 112 and a motion processing unit 114.

  The movement processing unit 112 performs processing for controlling the movement of the character (model object, moving object).

  More specifically, the movement processing unit 112 performs a process of moving (translating and rotating) the character in the object space (game space). The character movement process is performed by operating data (input data from the player) from the operation unit 160, character position and rotation angle (direction) in the previous frame (1/60 seconds, 1/30 seconds, etc.). Based on the above, it can be realized by obtaining the position and rotation angle of the character in the current frame (inter). For example, the position and rotation angle of the character in the (k−1) frame are Pk−1 and θk−1, and the position change amount (speed) and the rotation change amount (rotation speed) in one frame of the character are ΔP and Δ. Let θ. Then, the position Pk and the rotation angle θk of the character in the k frame can be obtained by the following equations (1) and (2), for example.

Pk = Pk-1 + ΔP (1)
θk = θk-1 + △ θ (2)
The motion processing unit 114 performs processing (motion reproduction, motion generation) for causing a character (model object) to perform motion (animation). The motion processing of the character can be realized by reproducing the motion of the character based on the motion data stored in the motion data storage unit 176.

  More specifically, the motion data storage unit 176 stores the position or rotation angle of each bone (part object, joint, motion bone constituting the character) constituting the character's skeleton (3 of the child bone relative to the parent bone). Motion data including the rotation angle around the axis) is stored. The motion processing unit 114 reads the motion data, and reproduces the motion of the character by moving each bone (part object) constituting the skeleton of the character based on the motion data (by deforming the skeleton shape). .

  The motion data stored in the motion data storage unit 176 is preferably created by attaching a sensor to a person in the real world and performing motion capture. However, the motion data is stored in a physical simulation (physical calculation is performed). It may be generated in real time by using simulation (which may be simulated physical calculation) or motion blending.

  In addition, in order to reproduce a realistic motion with a small amount of motion data, motion reproduction may be performed using inverse kinematics or the like.

  The action setting unit 116 performs various settings relating to actions performed by the character. More specifically, for example, when one character (a character operated by either one of the first and second players) performs the first action (movement, motion, etc.) (simultaneously or almost simultaneously) ), When the other character (character operated by the other player) performs the second action, the one character that has performed the first action is advantageously set in the battle or the game conditions, etc. . In addition, when one character performs the second action (simultaneously or substantially simultaneously) and the other character performs the third action, the one character that has performed the second action is It is set to be advantageous in offense and defense or game conditions. In addition, when one character performs the third action (simultaneously or substantially simultaneously) and the other character performs the first action, the one character that has performed the third action is It is advantageously set in the offense and defense or game conditions.

  In this case, the first action is, for example, a vertical attribute attack (attack) in which the attack direction (attack plane) of the character is substantially along a vertical plane (such as a vertical plane in the object space or a vertical plane in the character's local coordinate system). An attack whose direction is at least +45 degrees to −45 degrees with respect to a vertical plane) can be considered.

  Further, as a second action, for example, a lateral attribute attack (attack direction is horizontal plane) in which the attack direction (attack plane) of the character is substantially along the horizontal plane (horizontal plane in the object space or horizontal plane in the character's local coordinate system) On the other hand, an attack of at least + 45 ° to −45 °) can be considered.

  Further, as the third action, a moving action (running action, walking action, etc.) that moves in an arbitrary direction (direction instructed by the player through the operation input) in the object space can be considered.

  The hit check unit 118 performs a process of checking whether the attack of one character hits the other character. That is, when one character performs an attacking action, it is checked whether a part or a weapon such as a hand or a leg of the one character hits the body or weapon of the other character. In the case of a hit, the other character performs a motion (break motion, beat motion, hit motion) indicating that the character has been attacked.

  In addition, the hit check is performed using a pseudo hit area (simple object, hit box, hit volume) that simplifies and represents the trajectory drawn by the character's shape, character part (hand, foot), weapon, etc. You may make it perform.

  The image generation unit 120 performs image processing based on the results of various processes performed by the processing unit 100, generates a game image, and outputs the game image to the display unit 190. For example, when generating a so-called three-dimensional game image, first, geometric processing such as coordinate transformation, clipping processing, perspective transformation, or light source calculation is performed, and drawing data (primitive surface Position coordinates, texture coordinates, color (brightness) data, normal vectors, α values, etc.) given to the vertices (composition points) are created. Based on the drawing data (primitive surface data), the image of the object (one or a plurality of primitive surfaces) after the geometry processing is stored in the drawing buffer 174 (frame buffer, work buffer, or other pixel unit image information). ) Is drawn. Thereby, an image that can be seen from the virtual camera (given viewpoint) in the object space is generated.

  The sound generation unit 130 performs sound processing based on the results of various processes performed by the processing unit 100, generates game sounds such as BGM, sound effects, or sounds, and outputs the game sounds to the sound output unit 192.

  Note that the image generation system of the present embodiment may be a system dedicated to the single player mode in which only one player can play, or not only the single player mode but also a multiplayer mode in which a plurality of players can play. The system may also be provided.

  Further, when a plurality of players play, game images and game sounds to be provided to the plurality of players may be generated using one terminal, or connected via a network (transmission line, communication line) or the like. Alternatively, it may be generated using a plurality of terminals (game machine, mobile phone).

2. Features of the present embodiment Next, features of the present embodiment will be described with reference to the drawings. In the following, the case where the present embodiment is applied to a fighting game will be mainly described as an example, but the present embodiment can be widely applied to other games other than the fighting game.

2.1 Superiority vs. Superiority of Offense and Defense Now, in the 3D fighting games so far, despite being a 3D game, the superiority and inferiority of the offense and defense has been determined by the method that has been popular in 2D fighting games.

  For example, in FIG. 2A, when the character CH1 (a character operated by the first player; the same applies to the following description) attacks the character CH2 (a character operated by the second player; the same applies to the following description). The character CH2 defends against this attack by actions such as crouching, standing guard, crouching guard and the like.

  That is, the upper attack of the character CH1 is defended by standing guard, squatting, squatting guard and the like. Further, the middle guard attack of character CH1 is defended by a standing guard, a squatting guard or the like. Further, the lower attack of the character CH1 is defended by a squatting guard or the like.

  However, such superiority and inferiority of the offense and defense has been inherited from the custom of the two-dimensional fighting game, and is not ideal for use in the three-dimensional fighting game. That is, in the three-dimensional fighting game, as shown in FIG. 2B, the characters CH1 and CH2 can freely move around in the object space. Therefore, it is desirable to be able to realize a superiority / inferiority relationship of offense and defense utilizing the characteristics of such a 3D game.

  Therefore, in this embodiment, the superiority or inferiority relationship between the actions of the characters is determined by the method described below.

  That is, as shown in FIG. 3A, it is assumed that there are A1, A2, and A3 as actions performed by the character. In this case, for example, when the character CH1 is performing the motion A1 (first motion) and the character CH2 performs the motion A2 (second motion) at the same time or almost simultaneously, the CH1 performing the motion A1 is Set advantageously, CH1 wins.

  On the other hand, when the character CH1 is performing the operation A2, and the character CH2 performs the operation A3 (third operation) at the same time or almost simultaneously, the CH1 performing the operation A2 is advantageously set and CH1 wins.

  Further, when the character CH1 is performing the operation A3, and the character CH2 performs the operation A1 at the same time or almost simultaneously, the CH1 performing the operation A3 is advantageously set and CH1 wins.

  In this way, in FIG. 3A, the superiority / inferiority relationship of attack and defense is determined by a triangular relationship such that the operation A1 wins over the operation A2, the operation A2 wins over the operation A3, and the operation A3 wins over the operation A1.

  Therefore, the player who operates the character can immediately grasp what action should be taken to win the enemy simply by thinking about the triangular relationship in FIG. That is, the player can immediately recognize that the enemy is A2 and the enemy is A2 and loses if A3 is the action A1 by thinking of the triangular relationship in FIG. Similarly, when you are in action A2, you can immediately recognize that if the enemy is A3, you win if you are A1, and if you are action A3, you are losing if you are A1 and you are losing if you are A2. Therefore, it is possible to provide a suitable operating environment that is easy for the player to understand.

  When the game realized by the present embodiment is a weapon fighting game using a weapon such as a sword (sword), as shown in FIG. 3B, the operations A1, A2, A3 is desirably a vertical attribute attack B1, a horizontal attribute attack B2, and a movement operation B3, respectively.

  Here, the vertical attribute attack B1 is an attack (vertical cut attack or the like) classified into a vertical category, and is an attack in which the attack direction is substantially along the vertical plane. In this case, in the vertical attribute attack B1, the attack direction does not have to be completely along the vertical plane, and the attack is slightly oblique to the vertical plane (at least the angle formed with the vertical plane is +45 degrees to −45 degrees). Attack along the inner surface).

  The horizontal attribute attack B2 is an attack classified into a horizontal category (crossing attack or the like), and is an attack in which the attack direction is substantially along the horizontal plane. In this case, in the lateral attribute attack B2, the attack direction does not have to be completely along the horizontal plane, and the attack is slightly inclined with respect to the horizontal plane (at least an angle with the horizontal plane within +45 degrees to -45 degrees) (Attack along).

  Further, the moving action is an action in which the character moves in an arbitrary direction in the object space. In other words, this is an action in which the character moves in the direction of the player's movement instruction (lever input) using operation input, and includes, for example, a running action and a walking action.

2.2 Vertical attribute attack and horizontal attribute attack In the attack-and-defense relationship shown in FIG. 3B, when one character performs a vertical attribute attack and the other character performs a horizontal attribute attack, a vertical attribute attack is performed. One of the characters performed is advantageously set.

  More specifically, in FIG. 4, the character CH1 performs a vertical attribute attack (vertical cut attack), and the character CH2 performs a horizontal attribute attack (transverse attack) almost simultaneously with this.

  In this case, as shown in FIG. 5 and FIG. 6, the character CH1 performing the vertical attribute attack is advantageously set and won. That is, CH2 that has been attacked by the character CH1 performs a break motion or a defeated motion in which the weapon (a sword in a narrow sense) is shot down (an operation that indicates an attack in a broad sense). In addition, the attacked character CH2 is set inoperable for a given period.

  Here, the inoperable state is a state in which even if a player operating CH2 performs an operation input for operating CH2, the operation input is not accepted, and CH2 is inoperable for a certain period of time (rigid state) ).

  In a weapon fighting game, it is generally more likely that the player will win the horizontal attribute attack than the vertical attribute attack. The reason for this is that in a horizontal attribute attack, the attack surface (sword trajectory) becomes a horizontal plane, and in order to escape the attack, the character must move greatly, whereas in a vertical attribute attack, the attack surface is vertical. Therefore, it is possible to escape the attack by shifting the character's body a little. Accordingly, there is a problem that the player frequently uses a horizontal attribute attack with a high probability of winning, and the game development becomes monotonous.

  Therefore, in the present embodiment, as shown in FIGS. 4 to 6, when the vertical attribute attack and the horizontal attribute attack occur simultaneously, a technique is adopted in which the vertical attribute attack wins, thereby solving the above-described problem. doing. In other words, if such a method is adopted, even if a horizontal attribute attack is made, the player loses if the enemy makes a vertical attribute attack. Therefore, the player does not easily use the horizontal attribute attack easily. As a result, the mutual characters come out with various attacks, and various game developments can be realized.

  The hit check for vertical attribute attack and horizontal attribute attack is performed by checking whether the hit area (hit volume, hit box) of vertical attribute attack and hit area of horizontal attribute attack are hit (whether they are overlapped or crossed) It is desirable to judge by

  In this case, in this embodiment, in the hit check of the vertical attribute attack and the horizontal attribute attack, a pseudo hit area (hit volume, hit box) is used instead of the normal hit area.

  That is, as shown in FIG. 7A, in a normal hit check, a fan-shaped hit area HA1 is formed based on the current position of the weapon AR1 possessed by the character CH1 and the position in the previous frame. Then, a hit check is realized by determining whether or not the hit area HA1 has hit the enemy character CH2.

  However, according to this method, since it is very rare that the weapons AR1 and AR2 hit, an image expression in which the weapons AR1 and AR2 collide and rebound when the vertical attribute attack and the horizontal attribute attack occur simultaneously. Cannot be realized easily.

  Therefore, in this embodiment, the hit check of the vertical attribute attack and the horizontal attribute attack is performed using the pseudo hit areas VHA1 and VHA2 (hit volume, hit box) as shown in FIG.

  These pseudo (approximate) hit areas VHA1 and VHA2 are hit areas HA1 and HA2 (hit areas specified by the attack trajectory) formed by strictly calculating the trajectories of actual weapons AR1 and AR2 as shown in FIG. ) Is a larger (wider) pseudo area than these HA1 and HA2. For example, in FIG. 7B, a line that is assumed to be the position at which the arms AR1 and AR2 start swinging (starting position of the swing motion) and a line that is assumed to be the end position (end position of the swing motion) are opposed to each other. Fan-shaped plates having two sides are set in the pseudo hit areas VHA1 and VHA2.

  In this way, these pseudo-hit areas VHA1 and VHA2 can be made larger than the hit areas HA1 and HA2 that are only one frame in size. Therefore, hits of the weapons AR1 and AR2 occur more frequently than in the case of FIG. 7A, and when the vertical attribute attack and the horizontal attribute attack occur simultaneously, the weapons AR1 and AR2 collide and rebound. Images are generated frequently, and the effect of rendering images can be enhanced.

  As such pseudo hit areas VHA1 and VHA2, those of various shapes can be considered. For example, as shown in FIG. 7C, the pseudo hit areas VHA1 and VHA2 may have a three-dimensional shape (such as a sphere, a cylinder, or a prism) that includes the characters CH1 and CH2 and the weapons AR1 and AR2, or a weapon. A three-dimensional shape (such as a sphere, a cylinder, or a prism) that includes AR1, AR2, or a trajectory thereof may be used.

  Further, the frequency of hits of vertical attribute attacks and horizontal attribute attacks may be adjusted by variably controlling the size of the pseudo hit area.

  Also, the hit timing of the vertical attribute attack and the horizontal attribute attack can be determined by a method as shown in FIG. That is, a period T (hit period) during which the attack is effective is set between the start and end of the attack action (attack motion) of the character CH1. Then, if it is determined that the pseudo hit areas VHA1 and VHA2 have hit during the attack effective period T, it is determined that the hit event of the vertical attribute attack and the horizontal attribute attack has occurred. Then, by setting the character CH2 in an inoperable state (rigid state) for a period TN after the hit event occurs, the character CH1 can be advantageously set as compared to CH2.

2.3 Lateral attribute attack and moving action In this embodiment, as shown in FIG. 3B, when one character performs a lateral attribute attack, the other character performs a moving action (running). One character that has made a horizontal attribute attack is advantageously set.

  More specifically, in FIG. 9, the character CH1 performs a horizontal attribute attack (crossing attack), and the character CH2 performs a movement operation simultaneously or substantially simultaneously with this.

  In this case, as shown in FIG. 10 and FIG. 11, the character CH1 performing a lateral attribute attack is advantageously set and won. That is, the horizontal attribute attack of the character CH1 hits the character CH2, and the character CH2 is killed and performs a motion. In addition, the attacked character CH2 is set inoperable for a given period.

  By doing this, in the case of a horizontal attribute attack where the attack surface is a horizontal plane, it is difficult to escape the attack even if the character is moved, and expresses that the horizontal attribute attack is strong against the movement action become able to. As a result, a real and natural game image that can be satisfied by the player can be generated.

  In this case, in this embodiment, the amount of the axis follow-up correction for the character CH1 who has performed the lateral attribute attack is set to a large value.

  Here, the axis follow-up correction is correction for directing the direction DC1 toward the character CH1 to the direction D12 of the enemy character CH2, as shown in FIGS. 12 (A) and 12 (B). When the amount of this axis follow-up correction is increased, the degree of follow-up of the direction DC1 toward the character CH1 in the direction D12 of the character CH2 increases, and the attack of the character CH1 is likely to hit the character CH2. The amount of this axis follow-up correction is determined by the angular velocity in which the direction DC1 is directed in the direction D12 in each frame and the number of frames for which the axis follow-up correction is performed (period in which the axis follow-up correction is performed).

  In the present embodiment, the axis follow-up correction amount of the character CH1 performing the horizontal attribute attack is set to a value larger than the axis follow-up correction amount of other attack actions (for example, vertical attribute attack). Therefore, the direction DC1 that the character CH1 that is performing the lateral attribute attack faces easily follows the direction D12 of CH2. As a result, the attack of the character CH1 is likely to hit CH2, and CH1 can be advantageously set.

2.4 Moving Action and Vertical Attribute Attack In this embodiment, as shown in FIG. 3B, when one character performs a moving action when the other character makes a vertical attribute attack, the moving action is performed. One of the characters performed is advantageously set.

  More specifically, in FIG. 13, the character CH2 performs a vertical attribute attack (vertical cut attack), and the character CH1 performs a movement operation (an escape operation) simultaneously or substantially simultaneously.

  In this case, as shown in FIGS. 14 and 15, the character CH1 performing the moving action is advantageously set and won. In other words, even if the character CH2 makes a vertical attribute attack, the character CH1 can successfully dodge the upper body and escape the vertical attribute attack of CH2.

  By doing this, in the case of a vertical attribute attack where the attack surface is a vertical surface, it is possible to escape the attack by shifting the character's body a little, and the movement action is strong against the vertical attribute attack Can be expressed. As a result, a real and natural game image that can be satisfied by the player can be generated.

  In this case, in this embodiment, as shown in FIG. 16A, even when it is determined that the vertical attribute attack of the character CH2 hits the character CH1, the hit determination is canceled. .

  For example, the hit check of the vertical attribute attack of the character CH2 is performed using a hit area as shown in FIG. That is, when the hit area of the weapon AR2 of the character CH2 in FIG. 16A hits the character CH1 (when overlapped or intersected), it is determined that an attack has hit.

  However, when the character CH1 performs a moving operation at the same time or almost simultaneously with the character CH2 performing the vertical attribute attack, the hit determination is canceled and invalidated. As a result, the character CH1 can be advantageously set.

  It should be noted that simply canceling the hit determination of the vertical attribute attack of the character CH2 causes a situation in which the CH2 weapon AR2 is sunk into the CH1 but does not hit, causing the player to feel unnatural. There is a risk of feeling. Therefore, in this case, as shown in FIG. 14, the character CH1 is caused to perform a motion (motion) of turning the body sideways only by the upper body. This can prevent the player from feeling unnatural.

  Alternatively, as shown in FIG. 16B, outside the angle range including the direction DC2 facing the character CH2 (the range in which the first angle is the plus side and the second angle is the minus side with respect to the direction DC2). The hit determination may be canceled only when the condition that the character CH1 is located is satisfied.

  For example, if the hit determination of the vertical attribute attack of CH2 is canceled even though the character CH1 is located directly in front of the character CH2, a very unnatural image is generated.

  On the other hand, in the method of FIG. 16B, when the character CH1 is located in front of the character CH2, it is determined that CH1 is located within the angle range (direction range) RG, and the hit determination is not canceled.

  On the other hand, when the character CH1 is not located directly in front of the character CH2 but is located in a direction deviated from the front, that is, when CH1 is located outside the angle range RG, the hit determination is performed by the method of FIG. Will be cancelled. In such a case, even if the hit determination is canceled, the player does not feel so unnatural because the character CH1 seems to have escaped the attack of CH2 at the last minute. Therefore, it is possible to set the character CH1 more advantageously while generating an image that the player does not feel so unnatural.

  Further, for example, in FIG. 14, if an image is generated in which the vertical attribute attack of the other character is hit even though the hit determination is canceled, the player feels inconsistency.

  Therefore, in order to prevent such a situation, for example, as shown in FIG. 14, when the hit determination is canceled, the hit portion (hit portion) of the character CH1 is not seen from the virtual camera VC. It is desirable to change the position or direction (VD) of the virtual camera VC.

  More specifically, the position and direction of the virtual camera VC are set so that the character CH2 becomes an obstacle and the hit location of the character CH1 cannot be seen. In this case, the position and direction of the virtual camera may be changed according to the positional relationship between the characters CH1 and CH2. Note that the position and direction of the virtual camera VC may be set so that objects other than the character CH2 (effect objects such as blood splash, objects such as buildings and walls, etc.) cannot be seen as obstacles. .

  Further, if an image that appears to have hit the vertical attribute attack even though the hit determination is canceled, the player feels more unnatural when the replay image is generated.

  Therefore, in order to prevent such a situation, when the hit determination is canceled, a corrected image that does not appear that the vertical attribute attack of the other character hits one character when the replay image is generated. It is desirable to generate

  More specifically, the characters CH1 and CH2, the coordinates of the virtual camera VC (for example, absolute coordinates in the world coordinate system) and the like are sequentially stored in the storage means as replay information in order to generate a replay image. Also, a hit cancel flag (information indicating that the hit determination has been canceled) is also stored as replay information. At the time of replay, a corrected image is generated based on the stored coordinates and hit cancellation flag. More specifically, correction is performed to shift the stored coordinates (absolute coordinates) of the character CH2 as indicated by Q1 in FIG. 14, for example, and a replay correction image is generated. By doing so, it is possible to prevent the player from noticing that the hit determination has actually been canceled even though the hit was actually made, at the time of replay.

2.5 Adjustment of attribute parameters When the superiority / inferiority relationship of attack / defense is set as shown in FIGS. 3 (A) and 3 (B), attribute parameters (difficulty level setting parameter, handy setting parameter) related to character action / defense ) Adjustment is also important.

  That is, for example, when the attribute parameter of the action A1 in FIG. 3A is changed, if the attribute parameters of the actions A2 and A3 are not changed, the balance between superiority and inferiority of attack and defense may be lost.

  Therefore, in the present embodiment, as shown in FIGS. 17A and 17B, the attack of one of the first, second, and third operations (vertical attribute attack, horizontal attribute attack, and movement operation) is controlled. When an attribute parameter (a parameter that affects the balance of superiority and inferiority of attack and defense) is changed, the attribute parameters of other operations are also changed.

  Taking the size of the pseudo hit area that is one of the attribute parameters described in FIGS. 7B and 7C as an example, the pseudo hit area for one operation (for example, vertical attribute attack) is increased. When the size is reduced, the pseudo hit area for other operations (for example, horizontal attribute attack) is also increased or decreased in conjunction with this.

  Further, taking the effective attack period and the inoperable period as one of the attribute parameters described in FIG. 8 as an example, the effective attack period and the inoperable period for one operation (for example, vertical attribute attack) are lengthened or shortened. In this case, the effective attack period and the inoperable period for other operations (for example, horizontal attribute attacks) are also lengthened or shortened in conjunction with this.

  Further, taking the axis follow-up correction amount as one of the attribute parameters described in FIGS. 12A and 12B as an example, the axis follow-up correction amount for one operation (attack, movement) is increased or decreased. In this case, the axis follow-up correction amount for other operations (attack, movement) is also increased or decreased in conjunction with this.

  Also, taking the angle range RG, which is one of the attribute parameters, described in FIG. 16B as an example, when the angle range for one operation (attack, movement) is widened or narrowed, The angle range for other operations (attack, movement) is also increased or decreased in conjunction with this.

  By adjusting the attribute parameters as described above, various game balance adjustments can be realized while maintaining the balance of superiority and inferiority of the offense and defense.

3. Process of this embodiment Next, a detailed example of the process of this embodiment will be described with reference to the flowcharts of FIG. 18, FIG. 19, and FIG.

  FIG. 18 is a flowchart regarding a process (see FIGS. 4 to 8) for dropping an enemy's horizontal attribute attack by a vertical attribute attack.

  First, the player's operation input is accepted, and the action of the player character is set accordingly (step S1).

  Next, it is determined whether or not the attack flag of the player character is on (attacking) (step S2), and if not, the routine proceeds to a normal hit check process (step S9). On the other hand, if it is ON, it is determined whether or not the attack of the player character is a vertical attribute attack (step S3). If the attack is not a vertical attribute attack, the process proceeds to a normal hit check process.

  If it is a vertical attribute attack, it is determined whether or not the vertical attribute attack is within the effective period (step S4; see FIG. 8). If it is not within the effective period, the process proceeds to a normal hit check process. On the other hand, if it is within the effective period, it is determined whether or not the enemy character is in a horizontal attribute attack (step S5). If it is not in a horizontal attribute attack, the process proceeds to a normal hit check process.

  When the horizontal attribute attack is being performed, it is determined whether or not the vertical hit attack area of the player character's vertical attribute attack and the pseudo hit area of the enemy character's horizontal attribute attack have hit (step S6, FIG. 7B). , (C)), if there is no hit, the process proceeds to a normal hit check process. On the other hand, if there is a hit, the attacking flags of the player character and the enemy character are cleared so that unnecessary processing is not performed in the normal hit check processing (step S7). Then, the action of the enemy character is set to a break motion (the action in which the lateral attribute attack is dropped), and the enemy character is set to an inoperable state for a given period (step S8, FIG. 5, FIG. 6, FIG. 8). Then, the process proceeds to normal hit check processing.

  Thus, in this embodiment, when one character is performing a vertical attribute attack (within the effective attack time) and the other character is performing a horizontal attribute attack, as shown in FIGS. A hit check based on the pseudo hit areas VHA1 and VHA2 (first and second pseudo hit areas) is performed (step S6). In this case, when the attacking flag is cleared (step S7), hit areas HA1 and HA2 (first and second hit areas as shown in FIG. 7A) in the normal hit check process (step S9). ) Will not be hit-checked. On the other hand, when the hit check in step S6 by the pseudo hit areas VHA1 and VHA2 is not performed (when the condition for simultaneous occurrence of the vertical attribute attack and the horizontal attribute attack is not satisfied), the hit area in the normal hit check process in step S9 Hit check processing based on HA1 and HA2 is performed.

  FIG. 19 is a flowchart relating to a process (see FIGS. 9 to 12B) for effectively applying a lateral attribute attack to an enemy movement operation.

  First, the player's operation input is accepted, and the action of the player character is set accordingly (step S11).

  Next, it is determined whether or not the player character is attacking (step S12). If the character is not attacking, the routine proceeds to normal hit check processing (step S15). On the other hand, if the attack is in progress, it is determined whether or not the attack of the player character is a horizontal attribute attack (step S13). If the attack is not a horizontal attribute attack, the process proceeds to a normal hit check process.

  If it is a horizontal attribute attack, the axis follow-up correction amount of the own character is set to be large and the action control of the own character is performed (step S14; see FIGS. 12A and 12B). Then, the process proceeds to normal hit check processing.

  FIG. 20 is a flowchart relating to a process of escaping an enemy vertical attribute attack by a movement operation (see FIGS. 13 to 16B).

  First, it is determined whether or not the hit cancel flag of the player character is on (step S21). If it is on, the process proceeds to step S26. On the other hand, if it is not on, it is determined whether or not the player character is being beaten (step S22), and if it is being beaten, the process proceeds to a normal hit check process (step S28).

  If the attack is not being performed, it is determined whether the attack of the enemy character is a vertical attribute attack (step S23). If the attack is not a vertical attribute attack, the process proceeds to a normal hit check process. On the other hand, if the attack is a vertical attribute attack, it is determined whether or not an operation input for instructing the running motion of the player character has been performed (step S24). Move to hit check processing.

  If a running motion instruction has been issued, the hit cancel flag of the player character is set on (step S25).

  Next, it is determined whether or not the hit determination has been canceled by the hit cancellation flag despite the enemy attack being hit (step S26; see FIGS. 16A and 16B), and canceled. If it does, the action of the player character is set to dodge the enemy's vertical attribute attack (step S27; see FIGS. 14 and 15). Then, the process proceeds to normal hit check processing.

4). Hardware Configuration Next, an example of a hardware configuration capable of realizing the present embodiment will be described with reference to FIG.

For example, if a physical simulation for moving or moving an object requires processing such as matrix operation, a program operating on the main processor 900 instructs (requests) the processing to the coprocessor 902. )

  The geometry processor 904 performs geometry processing such as coordinate transformation, perspective transformation, light source calculation, and curved surface generation, has a product-sum calculator and a divider capable of high-speed parallel computation, and performs matrix computation (vector computation). Run fast. For example, when processing such as coordinate transformation, perspective transformation, and light source calculation is performed, a program operating on the main processor 900 instructs the geometry processor 904 to perform the processing.

  The data decompression processor 906 performs a decoding process for decompressing the compressed image data and sound data, and a process for accelerating the decoding process of the main processor 900. As a result, a moving image compressed by the MPEG method or the like can be displayed on the opening screen, the intermission screen, the ending screen, or the game screen. Note that the image data and sound data to be decoded are stored in the ROM 950 and the CD 982 or transferred from the outside via the communication interface 990.

  The drawing processor 910 performs drawing (rendering) processing of an object composed of primitives (primitive surfaces) such as polygons and curved surfaces at high speed. When drawing an object, the main processor 900 uses the function of the DMA controller 970 to pass the object data to the drawing processor 910 and transfer the texture to the texture storage unit 924 if necessary. Then, the rendering processor 910 renders the object in the frame buffer 922 at high speed while performing hidden surface removal using a Z buffer or the like based on the object data and texture. The drawing processor 910 can also perform α blending (translucent processing), depth cueing, mip mapping, fog processing, bilinear filtering, trilinear filtering, anti-aliasing, shading processing, and the like. When an image for one frame is written in the frame buffer 922, the image is displayed on the display 912.

  Operation data from the game controller 942 (lever, button, chassis, pad type controller, gun type controller, etc.), save data from the memory card 944, and personal data are transferred via the serial interface 940.

  The ROM 950 stores system programs and the like. In the case of an arcade game system, the ROM 950 functions as an information storage medium, and various programs are stored in the ROM 950. A hard disk may be used instead of the ROM 950.

  The RAM 960 is used as a work area for various processors.

  The DMA controller 970 controls DMA transfer between the processor and memory (RAM, VRAM, ROM, etc.).

  The CD drive 980 drives a CD 982 (information storage medium) in which programs, image data, sound data, and the like are stored, and enables access to these programs and data.

  The communication interface 990 is an interface for transferring data to and from the outside via a network. In this case, as a network connected to the communication interface 990, a communication line (analog telephone line, ISDN), a high-speed serial bus, or the like can be considered. By using a communication line, data transfer via the Internet becomes possible. Further, by using the high-speed serial bus, data transfer with other image generation systems becomes possible.

  Note that all of the means of the present invention may be realized only by hardware, or only by a program stored in an information storage medium or a program distributed via a communication interface. Alternatively, it may be realized by both hardware and a program.
