Description

  The present invention relates to a game program and a game apparatus that control the movement of a character in a virtual game space.

  Conventionally, there are games such as an action game and a role-playing game that cause a player character to move in a virtual game space in accordance with a player's operation. In this type of game, in addition to the player character, for example, a non-player character such as an enemy character that attacks the player character also appears. The non-player character is a character that cannot be directly operated by the player, and is set to act in the game space according to a predetermined rule.

  In such characters (player characters and non-player characters), an attack hit determination (collision) is provided for each part of the character (head, arm, foot, torso, etc.) and received for each part. A mode has been proposed in which the performance of each part is reduced according to the attack damage (for example, when the arm is damaged, the attack power is reduced, and when the foot is damaged, the moving speed is reduced) (for example, a patent) Reference 1).

  There has also been proposed an aspect in which a single character is generated by appropriately selecting and combining parts for each part constituting the two characters (see, for example, Patent Document 2).

  However, even in such a conventional game, since the behavior of the character does not change significantly in the game space (while the game is in progress), it is difficult to diversify the character's action presentation in the game. is there. In particular, in the conventional game, it is not expressed that the characteristic of the character changes positively in the game space, and there is a limit to the character's action presentation.

  Therefore, an object of the present invention is to provide a game program and a game apparatus that can diversify the action effects of a character while the game is in progress.

A game program according to the present invention includes a computer, a game space generation unit that generates a virtual game space in which a character moves, a character movement control unit that controls the movement of the character in the game space, and the character has a predetermined condition. Condition determining means for determining whether or not the condition determining means, when the condition determining means determines that the predetermined condition is satisfied, function as a part mutation means for mutating a predetermined part into a predetermined shape,
The character action control means controls the action of the character so as to perform different actions according to the changed part when the predetermined part is changed, and the character is a plurality of parts constituting the character. At least two of these are set to be mutable.

  Character damage determining means for determining damage to be applied to the character for each of a plurality of parts is provided, and the condition determining means is configured to determine whether the damaged part is a predetermined part related to the part. Whether or not the condition is satisfied is determined, and when the condition determining means determines that the predetermined condition is satisfied, the corresponding part may be changed to a predetermined shape.

  The part mutation means allows a plurality of parts of the character to be in a mutated state, and the character motion control means is in a case where one part is mutated when a plurality of parts are mutated. The motion of the character may be controlled so that a motion different from that of the character can be executed.

  The site variation means may vary the variation mode based on the state of the character.

  The site mutation means may allow the site of the character to be mutated multiple times.

  Further, the computer acquires basic motion acquisition means for acquiring basic motion data related to the basic motion of each part of the character, and mutated part motion for acquiring mutated part motion data related to the action of the mutated part for each part after the mutation. The mutated part motion data is associated with post-mutation basic motion data related to an action other than the mutated part of the character when the corresponding part is mutated. In the basic motion data, a priority for using the motion data is set for each part, and when the plurality of parts are mutated, the character motion control means has the character other than the mutated part. The motion of each part is represented by the basic motion data and Motion data to be used for each part may be selected from the plurality of post-mutation basic motion data relating to different parts according to the priority, and the motion of the character may be controlled based on the selected data. .

Therefore, multiplayer in which a plurality of people work together to advance a game is possible.

[Functional configuration of game device]
FIG. 2 is a block diagram showing a functional configuration of the game apparatus 2 shown in FIG. As shown in FIG. 1, the game apparatus 2 includes a control unit 4 including a CPU 10, an HDD 14, a ROM 15, a RAM 16, a graphic processing unit 17, a video conversion unit 18, an audio synthesis unit 20, an audio conversion unit 21, a network interface 25, and the like. Act as a computer. Then, as shown in FIG. 2, the control unit 4 of the game apparatus 2 executes the game program 30a of the present invention, so that the game space generation means 41, the character motion control means 42, the character damage determination means 43, the condition determination The functions of the means 44, the site mutation means 45, the basic motion acquisition means 46, the mutation site motion acquisition means 47, etc. are exhibited.

  Among these, the game space generation means 41 generates a virtual game space in which the character operates and each character that operates in the game space, and displays the character on the monitor 19. For example, the game space generation means 41 reads data such as objects and textures included in the game data 30b as the player character moves, and generates a three-dimensional virtual game space. Furthermore, in order to display the game space on the monitor 19 of the game apparatus 2, the game space generation means 41 generates a two-dimensional image when the generated game space is photographed with a predetermined virtual camera.

  The character action control means 42 controls the action of the character in the game space according to the operation of the controller 24 by the user and the progress of the game.

  The character damage determination means 43 determines the damage applied to the character (the presence / absence of damage and the amount of damage) for each of a plurality of parts when the character is damaged. Specifically, the character damage determination means 43 compares the coordinates of damage elements (weapons used for attack, objects to be contacted, etc.) with the coordinates of the hit areas (boundary coordinates) set for each part, If the coordinates of the damage element are within the hit area (exceeding the boundary coordinates), the damage amount is stored as damage to the part of the hit area. If the same part has been damaged by the previous time, a value obtained by accumulating the previous damage amount and the current damage amount is stored.

  Further, the condition determining means 44 determines whether or not the character satisfies a predetermined condition. In this embodiment, it is included in one of the predetermined conditions that the character has been damaged, and when the character has received the damage, the condition determination unit 44 determines that the damaged part is a predetermined value related to the part. It is determined whether a condition (for example, exceeding a predetermined amount of damage, winning in a lottery process having a predetermined winning probability, etc.) is satisfied. That is, the predetermined conditions in the present embodiment include that the part is damaged and that the condition that the damaged part is mutated is satisfied. Note that the predetermined condition may be that the part is only damaged (it is always mutated when the part that can be mutated is damaged).

  When the condition determining unit 44 determines that the predetermined condition is satisfied, the part changing unit 45 changes the corresponding part into a predetermined shape. The shape after mutation is acquired from the game data 30b stored in association with each part as object data. The basic motion acquisition means 46 acquires basic motion data relating to the basic motion of each part of the character (the motion of the part that is not mutated) from the game data 30b. The mutation part movement acquisition means 47 acquires the mutation part motion data relating to the movement of the changed part from the game data 30b for each part after the mutation.

[Motion data]
In the present embodiment, each character is generated by reading the corresponding character data from the game data 30b. The character data constituting each character includes skeleton data indicating the relative positions of each joint of the character, object data indicating the shape of each part of the character (head, arms, legs, torso, etc.), part It consists of effect data indicating the effect expression (display information such as blood splash and liquid displayed on the object, voice information such as voice and tearing sound at the time of damage), motion data indicating the operation of each part, etc. Is done. These data are set for the character before mutation. The object data includes position coordinates corresponding to the skeleton data of each part, and the character motion control means 42 moves each part in accordance with the relative movement of the joint position of each part based on the motion data. Thus, the movement of the character is controlled. Further, the contact area is similarly moved in accordance with the relative movement of each joint (each part). Note that the relative position of each joint of the character in the skeleton data may be based on a predetermined reference portion (for example, the head) of the character, or a position coordinate in a predetermined coordinate system outside the character. It may be.

  The game data 30b includes basic motion data related to the basic motion of the character and mutated site motion data related to the motion of the mutated site, which will be described later, as the motion data. Mutation site motion data is provided for each site to be mutated. Furthermore, the mutated part motion data includes post-mutation basic motion data related to the movement of the character other than the mutated part when the corresponding part is mutated, and the post-mutation basic motion data is associated with the mutated part. It has been. Each data after the mutation is also preset according to the character.

  The three types of motion data are selected and used according to the presence / absence of a mutation at a later-described site. The motion of each part of the character in a state where none of the parts is mutated is defined by basic motion data (for example, walking in a balanced manner). In addition, the behavior of the mutation site in the character in a state where the mutation site exists is defined by the mutation site motion data (for example, a special attack is performed). Then, the movement of the part other than the mutation part in the character in a state where the mutation part exists is defined by the post-mutation basic motion data (the left-right balance is deteriorated depending on the mutation part and walks awkwardly). For this reason, the mutation site motion data related to the mutation site and the post-mutation basic motion data related to the site other than the mutation site at that time are associated with each other.

  FIG. 3 is a diagram illustrating an example of basic motion data in the present embodiment. In the example shown in FIG. 3, the game data 30b includes basic motion data A001, which indicates basic actions of the humanoid enemy character E1 (including basic actions such as walking and battle-related actions when encountering a player character). , A006... Are associated with each basic operation. The basic motion acquisition means 46 acquires basic motion data related to the basic motion of each part of the character E1, and the character motion control means 42 selects the action content to be performed by the character E1 according to the game program 30a and the play situation. The basic motion data corresponding to the action content selected according to a predetermined rule is read from the acquired basic motion data, and the character E1 is operated.

  For example, when the character E1 is made to walk, the character motion control means 42 reads the basic motion data A002 and executes the motion of each part based on the basic motion data A002. In FIG. 3, the basic motion data is represented as one piece of data for the whole body, but may be different for each part, or may be different for the upper body and the lower body. The details of the motion data are publicly known and will not be described. Each motion requires a predetermined frame from the start to the end. Further, the motion data includes angle data of each joint for each frame (for example, 1/60 seconds), and the character is operated by inputting the angle data to each joint in each frame. For example, in the case of walking motion, 60 frames are required from the start to the end of the motion, and the walking motion is repeatedly performed until the position coordinate (origin) of the character matches the target position.

  The character E1 is set with status values such as physical strength, attack power, and defense power, and conditions for changing the part when receiving damage, which will be described later. Status values and conditions can be set for each character and part. For example, in general, the body portion has high values of physical strength and defense strength, but the other portions are set to have low values of physical strength and defense strength.

[Site mutation operation]
Hereinafter, the flow of control for the part mutation operation in which a part is mutated when damage is applied to a predetermined part of the character E1 will be described. FIG. 4 is a diagram showing a variation mode in each part of the character E1 in the present embodiment. In FIG. 4, the character E1 before mutation is E1A, and the character E1 after mutation is E1B to E1F.

  The pre-mutation character E1A is a humanoid character having a right arm P1a, a foot P2a, a head P3a, a torso P4a, and a left arm P5a. Different hit areas and status values are set for the respective parts P1a to P5a. Furthermore, the presence / absence of mutation and the conditions for mutation are set for each of the sites P1a to P5a. The character E1 in the present embodiment is set such that three parts (the right arm part P1a, the foot part P2a, and the head part P3a) among the plurality of parts P1a to P5a constituting the character E1 can be changed.

  The condition for mutating the damaged part is, for example, the ratio of the amount of damage to each part (for example, mutating when the physical strength value assigned to each part becomes less than 50% of the assigned maximum value) You may set the probability of mutation for each part (for example, if you receive damage, it will change with a probability of 50% regardless of the amount of damage), or a combination of these (for example, damage received) If the physical strength value of the part is less than 50% of the maximum value, it may be changed with a probability of 50%). In addition, the probability may be set stepwise (for example, the probability of mutation increases as the amount of damage increases). Moreover, it is good also as changing the conditions of variation | mutation according to the progress of a game (The place where the character E1 is arrange | positioned, the achievement rate of an event, the level of a player character, etc.).

  Further, in the present embodiment, as shown below, the two sites are allowed to be mutated at the same time, but three or more sites are not allowed to be mutated. Yes. However, the present invention is not limited to this, and may allow three or more sites to be mutated simultaneously, or may not allow a plurality of sites to be mutated simultaneously.

  FIG. 5 is a flowchart showing the flow of the site mutation operation process in the present embodiment. As shown in FIG. 5, when the character E1A before mutation is generated, a count indicating the number of mutation sites is set to C = 0 (step S1). Further, as described above, at the time of generating the character E1A, the basic motion acquisition unit 46 acquires basic motion data regarding the basic motion of each part of the character E1A, and the character control unit 44 is based on the basic motion data. The character E1A is operated. The character damage determination means 43 monitors whether or not some kind of damage event has occurred to the character E1A (such as being attacked or colliding with an object) (step S2), and the character E1A has a damage event ( If damage has been added (Yes in step S2), it is determined for each part how much damage was given to which part P1a to P5a (step S3), and given to the corresponding part of character E1A The damage is counted for each part (the amount of damage is accumulated and stored) (step S4).

  As a result, the character damage determination unit 43 determines whether or not the character E1A satisfies a death condition such that the character E1A falls below a predetermined physical strength value (step S5). If the character E1A satisfies the death condition (Yes in step S5), the character E1A is subjected to death processing, and this flow ends.

  On the other hand, when the character E1A does not satisfy the death condition (No in step S5), the condition determination unit 44 determines whether or not the count C <2, that is, whether or not there are two or more sites that have already been mutated. Determination is made (step S6). If there are two or more sites that have already been mutated (No in step S6, state of characters E1E and E1F described later), the process returns to step S2 in order not to mutate any other sites.

  If the number of mutated sites is less than 2 (Yes in step S6, character E1A or the state of characters E1B, E1C, E1D described later), the condition determining means 44 determines that the damaged site is as described above. It is determined whether or not a predetermined condition regarding the part is satisfied (step S7). In the present embodiment, the predetermined condition includes that the corresponding site is not already mutated. That is, the condition determination unit 44 determines that the predetermined condition is not satisfied (No in step S7) when the damaged part has already been mutated. In the case where it is allowed that the corresponding site is mutated a plurality of times, such a condition determination need not be performed.

  When the condition determining unit 44 determines that the predetermined condition is satisfied (Yes in step S7), the part changing unit 45 changes the corresponding part into a predetermined shape. Specifically, the mutation site motion acquisition unit 47 acquires the mutation site motion data of the corresponding site and the object data after the mutation of the corresponding site (step S8), and the site mutation unit 45 acquires the object data after the mutation. Based on the above, the corresponding part is mutated into a predetermined shape (step S9). The character action control means 42 controls the action of the mutation part based on the part mutation motion data. At this time, the character action control means 42 adds 1 to the count C (step S10). The operation of the mutation site is controlled based on the site mutation motion data as described above, but the other sites are controlled based on the post-mutation basic motion data associated with the mutation site motion data. Therefore, by mutating a part of the part, not only the part but also the action of the entire character is different from that before the mutation, and the action after the mutation can be expressed realistically (details will be described later). ).

  FIG. 6 is a diagram illustrating an example of the mutation site motion data of the post-mutation right arm P1b of the character E1 in the present embodiment. FIG. 7 is a diagram illustrating an example of mutation site motion data of the rear foot portion P2c of the character E1 in the present embodiment. In addition, although illustration and description are abbreviate | omitted, it has the same data also about the back head P3d of a mutation. In Steps S8 to S9, when the right arm P1a is mutated to the post-mutation right arm P1b, the operation of the post-mutation right arm P1b is controlled based on the mutation site (right arm) motion data shown in FIG. In addition, when the foot P2a is mutated to the mutated foot (wing) P2c, the operation of the mutated foot P2c is controlled based on the mutation site (foot) motion data shown in FIG.

  Further, as shown in FIGS. 6 and 7, the mutation site motion data is associated with the post-mutation basic motion data relating to the operation other than the mutated site of the character E1 when the corresponding site is mutated. At this time, the basic motion data after mutation and the mutation site motion data are associated with each common operation content (for example, standby, walking, running, etc.). In FIG. 6, the mutation part motion data B001,..., B009,... Relating to the movement of the right arm P1b after mutation and the basic movement data A001B,. In FIG. 7, the mutation part motion data C001,..., C016,... Related to the movement of the post-mutation foot P2c and the basic movement data A001C,. Are associated according to the operation content. Then, when the part is mutated, the character action mutating means 42 reads the mutated part motion data relating to the action of the part after the mutation and the post-mutation basic motion data relating to the action of the other part. The motion of the character E1 after the mutation is controlled based on the basic motion data.

  Here, the necessity of the post-mutation basic motion data will be described. For example, when the right arm portion P1a of the character E1 is mutated to the sickle-shaped right arm portion P1b, the right arm portion P1b is longer and larger than the left arm portion P5a that is not mutated, so the right arm portion P1b is heavier than the left arm portion P5a and has inertia force. The character E1B is controlled so as to be large. At this time, even if it is attempted to control only the right arm P1b in such a manner, a sense of incongruity occurs. For this reason, for example, when performing the walking motion, the character motion control means 42, for example, swings the right arm portion P1b so as to swing the right arm portion P1b based on the mutation site motion data B002 of the right arm portion P1b corresponding to the walking motion. To control. In accordance with this, the character motion control means 42 controls the torso P4a so as to raise the right shoulder, for example, based on the post-mutation basic motion data A002B, or the foot P2a seems to be difficult to walk due to the deterioration of the left / right balance. To control. Thereby, it can be made to show natural operation | movement according to an external appearance, and the realistic feeling of a game can be improved.

  Moreover, the post-mutation basic motion data is associated with the mutation site motion data, and is not associated with the pre-mutation basic motion data (FIG. 3). In other words, regarding the basic motion, the character control means 42 reads out only the basic motion data (FIG. 3) and executes motion control before the site mutation among all the basic motion data before and after the mutation. After the mutation, only the corresponding basic motion data (FIG. 6 or FIG. 7) is read and the operation control is executed. This eliminates the need to read out all the basic motion data before and after the site mutation at a time, thereby reducing the amount of one-time reading and the capacity of temporary storage. Therefore, even when the number of mutation sites increases, it is possible to prevent the processing speed from being lowered when performing the basic operation.

  Through the processing as described above, the character motion control means 42 controls the motion of the character E1 so that when the damaged portion of the character E1 is mutated, different motions are possible depending on the mutated portion. . Then, the above steps S2 to S10 are repeatedly executed until the character E1 is determined to die. At the time of mutation, each status value of the site after mutation may be recovered, or may be increased from the maximum value of each status value before mutation. Further, when a mutation occurs, the status value of the entire character E1 may be recovered or increased from the maximum value before the mutation.

  Here, the example of a variation | mutation is demonstrated based on FIG. First, when the right arm P1a of the character E1A before mutation is damaged and the condition determining means 44 determines that the predetermined condition regarding the right arm P1a is satisfied (Yes in step S7 in FIG. 5), the site changing means 45 Generates a character E1B having a mutated right arm P1b instead of the right arm P1a. In the example of FIG. 4, the right arm portion P1a of the character E1A before the mutation has a gun and can be remotely attacked by the gun, but after the mutation, the character E1A changes to the right arm portion P1b having a sickle shape. A melee attack with a sickle is an attack method.

  In addition, when the foot P2a of the character E1A before mutation is damaged and the condition determining unit 44 determines that the predetermined condition regarding the foot P2a is satisfied, the site mutation unit 45 performs the mutation instead of the foot P2a. A character E1C having a hind leg part P2c is generated. In the example of FIG. 4, instead of the leg portion P2a that can be walked, the mutated foot portion (wing portion) P2c with a new torso and wings is mutated, and the character E1C after the variation is the character before the variation. It is possible to fly with E1A upside down.

  In the present embodiment, the foot part P2a is set as one part (one hit determination and one mutation part) on both feet, but one leg is another hit determination and each is independently mutated. It is also possible to perform the condition determination. Alternatively, each leg may be determined as another hit determination, and both legs may be mutated at once when both legs are damaged (this is a predetermined condition).

  In addition, when the head P3a of the character E1A before mutation is damaged and the condition determining unit 44 determines that the predetermined condition regarding the head P3a is satisfied, the site mutation unit 45 performs the mutation in place of the head P3a. A character E1D having the back of the head P3d is generated. In the example of FIG. 4, an attack means is obtained in which the head is transformed into a post-mutation head P3d having a monster-like head instead of the human head P3a, and mucus is discharged from the tip of the head.

  Further, in the characters E1B, E1C, E1D in a state where one of the right arm P1a, the foot P2a, and the head P3a is mutated (when C = 1 in step S6 in FIG. 5), the right arm P1a, the foot If the part of P2a and the head P3a that is not mutated is damaged and the condition determining unit 44 determines that the predetermined condition relating to the part is satisfied, Mutate similarly. That is, for example, when the character E1B having the post-mutation right arm P1b is damaged by the foot P2a and the condition determining means 44 determines that the predetermined condition regarding the foot P2a is satisfied, and the post-mutation foot (wings Part) When the character E1C having P2c is damaged by the right arm part P1a and the condition determining means 44 determines that the predetermined condition regarding the right arm part P1a is satisfied, the site mutating means 45 changes the right arm part P1b after the mutation and the mutation A character E1E having a hind leg (wing) P2c is generated. Further, for example, when the character E1B having the post-mutation right arm part P1b is damaged by the head P3a and the condition determining means 44 determines that the predetermined condition relating to the head P3a is satisfied, and the character having the post-mutation head P3d If the right arm P1a is damaged in E1D and the condition determining means 44 determines that the predetermined condition relating to the right arm P1a is satisfied, the site mutating means 45 has the character E1F having the mutated right arm P1b and the mutated back head P3d. Is generated.

In the character E1 having six character variation modes E1A to E1F as shown in FIG. 4, conventionally, six patterns of motion data are required. On the other hand, according to the present invention, there are four patterns of motion data (basic, post-mutation right arm part (sickle-shaped arm part), post-mutation foot part (wing part), mutated back head part (head that spits mucus)) Mu As the number of mutation modes increases, the difference in the number of necessary motion data increases remarkably. Thus, the configuration of the present invention can effectively reduce the number of data compared to the conventional configuration. In this embodiment, for convenience of explanation, an example of a character having six mutation modes as shown in FIG. 4 is given. However, the number of mutation modes is not limited to this, and more various mutation modes are applied. can do. For example, when the number of mutation sites is n (> 0), 2 ⁿ character mutation modes can be created with n + 1 patterns of motion data.

  The character motion control means 42 performs a special action (special attack) utilizing the characteristics of the characters E1B to E1F, which are different from those before and after the mutation when one part is mutated, after the mutation. It can be performed according to E1B to E1F. For example, the character E1B in which the right arm P1a is mutated to P1b has a plurality of sickle attack variations (mutation site motion data B008, B009) that can give different damage depending on how the sickle-shaped right arm is swung. ing. Further, in the character E1C in which the foot P2a is changed to P2c, a gun shooting attack (mutation site motion data C013) in which the gun held by the right arm P1a is shot, or a body attack to the player character from the flying state ( Mutation site motion data C014) can be executed.

  As described above, in one character E1A, the game progresses by mutating to characters E1B to E1F having a plurality of different characteristics (different movement modes, attack patterns, etc.) according to the manner of attack of the player character. The action effects of the character E1 can be diversified. In particular, the characteristics of the character E1 can be positively changed in the game space (the character is weakened as well as weakened), so that the variation of the action presentation of the character E1 can be widened. Moreover, it is good also as changing the status value of the whole mutated character E1B-E1F according to the site | part mutated. By combining these, one character E1A can be mutated into characters E1B to E1F having a plurality of characteristics as shown below.

  As shown in the above table, the characteristics of the character E1 can be changed in a complicated manner depending on the mutation site. For example, when the player character wants to approach the character E1 and attack, the right arm P1a is attacked to mutate the right arm P1a, thereby eliminating the remote attack means of the character E1 and making it easy to approach and attack. However, instead, the attack power of the character E1 is increased and it is easy to receive a large damage. Further, by attacking the foot P2a of the character E1 and mutating the foot P2a, the accuracy rate (to the player character) by the attack of the character E1 can be lowered, but the moving means becomes flying. Since the weak point becomes a wing (a new body with a growing wing), a remote attack is required when the player character attacks the character E1, and it is difficult to hit. Further, by attacking the head P3a of the character E1 and mutating the head P3a, the area of the head, which is a weak point of the character E1, increases, so that the hit determination area increases, and the player character attacks. Although it becomes easy to hit, since the attack means by the character E1 increases, a player character becomes easy to receive a damage.

  Thus, even if it is the same character E1, the action and status value of the character E1 can be changed variously by changing a variation | mutation part, and the action effect of the character E1 in the game progress can be diversified. Thereby, even if the same enemy character E1 appears more than once, it is possible to perform an effect that does not bore the player. Further, since a plurality of capture methods can be created in one character E1, different capture methods can be employed depending on the possessed weapons and preferences of the player character, the weaknesses of the operation, and the like.

  Further, the character action control means 42 controls the action of the character E1 so that when a plurality of parts are mutated, the action different from that when one part is mutated can be executed. For example, in a character E1E in which the right arm portion P1a is mutated to P1b and the foot portion P2a is mutated to P2c, a grabbing attack at the time of an arm mutation that applies an attack after grabbing the player character with a sickle-shaped right arm (see FIG. 7). Rotation attack at the time of arm mutation (mutation site (shown in FIG. 7) (rotation site (foot) motion data C015 and mutation site (arm) motion data B015C)) and a sickle-shaped right arm by rotating the whole body Foot) motion data C016 and mutation site (arm) motion data B016C).

  Each mutation site motion data and corresponding post-mutation basic motion data when a plurality of sites are mutated are included in the mutation site motion data for any one of the plurality of mutated sites (this book In the embodiment, as shown in FIG. 7, it may be included in the mutation site motion data regarding the rear foot P3c of the mutation), or may be provided with mutation site motion data dedicated to a plurality of sites that have been mutated separately. When the plurality of parts are mutated, not only the actions based on each of the plurality of parts are simply combined but also the action effects of the character E1 can be further diversified by causing new actions to be performed.

  In addition, when multiple parts are mutated, the basic motion data that defines the basic motion other than that part is the basic motion data (the basic motion data before mutation and the basic motion data after mutation of the mutation part). May be selected according to the priority. Specifically, in the basic motion data and the basic motion data after mutation, a priority for using the data is set for each part, and the character motion control means 42 is in a state where a plurality of parts are mutated, For the motion of each part of the character E1 other than the mutated part, the motion data to be used for each part is selected from the basic motion data and the plurality of post-mutation basic motion data regarding the mutated part according to the priority, The motion of the character E1 may be controlled based on the selected data. Thereby, the motion data after mutation when a plurality of sites are mutated can be shared to some extent, and the capacity of the game data 30b can be reduced.

  Here, the display process of the character E1 at the time of site | part variation is demonstrated. FIG. 8 schematically shows a site mutation process in character E1 shown in FIG. FIG. 8 shows a process from the character E1A before mutation through the character E1B in which the right arm P1a is mutated to P1b to the character E1E in which the foot P2a is further mutated to P2c.

  As shown in FIG. 6, the mutation site motion data of the right arm P1b after the mutation includes the mutation site motion data B010 related to the operation of the right arm P1b at the time of the right arm mutation and the after-mutation related to the operation of the site other than the right arm P1b Basic motion data A010B is included. Further, as shown in FIG. 7, the mutation site motion data of the post-mutation foot P2c includes the mutation site motion data C017 related to the motion of the foot P2c at the time of foot mutation and the motion of the site other than the right arm P2c at that time. Post-mutation basic motion data A017C is included.

  As described above, in the character E1A before mutation, when the right arm part P1a is damaged and the predetermined condition in the right arm part P1a is satisfied, the site mutation means 45 expresses damage in the right arm part P1a before mutation. Processing (by displaying a damage display on the right arm P1a or executing motion data of the right arm P1a at the time of damage) is executed. Subsequently, the site mutation means 45 executes a process for making the right arm P1a before the mutation transparent or a process for deforming (blowing, shrinking, rupturing, etc.) (shown as a broken line P1a ′ in FIG. 8). .

  Subsequently, the site mutation means 45 reads the mutation site motion data B010 and the post-mutation basic motion data A010B after the transparency or deformation processing of the right arm portion P1a or in parallel with the processing, and based on this, the post-mutation right arm portion A process of displaying the right arm P1b ′ during the mutation to P1b is executed. At this time, based on the effect data associated with the display process, an effect expression (for example, a mist that squirts blood spray or body fluid) that makes the switching from the right arm P1a before the mutation to the right arm P1b after the mutation more smoothly appear. Etc.) may be performed together. When the mutation process is completed, the character motion control means 42 appropriately reads the part mutation motion data B001,..., B009, ... and the post-mutation basic motion data A001B, ..., A009B, ..., and then the right arm part P1b after the mutation. The motion control of the character E1B having

  Further, when the character E1B receives damage to the foot P2a and satisfies a predetermined condition in the foot P2a, the site mutation means 45 performs damage expression processing (damage display on the foot P2a before the mutation). Display on the part P2a, or execute motion data of the foot part P2a at the time of damage). Subsequently, the site mutation means 45 executes a process for making the foot part P2a before the mutation transparent or a process for deforming (blowing, shrinking, rupturing, etc.) (shown as a broken line P2a ′ in FIG. 8). .

  Subsequently, the site mutation means 45 reads the mutation site motion data C017 and the post-mutation basic motion data A017C after the transparency or deformation of the foot P2a or in parallel with the processing, and based on this, the post-mutation foot A process of displaying a new trunk portion and wing portion P2c ′ instead of the foot portion in the middle of the mutation to P2c is executed. When the mutation process is completed, the character motion control means 42 appropriately reads the site mutation motion data C001,..., C016, and post-mutation basic motion data A001C,. Then, the motion control of the character E1E having the right arm portion P1b after the mutation is performed.

  Thus, by expressing the movement between before and after the mutation, it is possible to enhance the presence in the game. In addition, since the motion data at the time of mutation is also associated with the mutation site motion data related to the operation of the site after the mutation, the amount of data to be read at a time can be reduced and the processing speed can be prevented from being lowered.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various improvements, changes, and modifications can be made without departing from the spirit of the present invention.

  For example, combinations of character variations are not limited to the above embodiment, and various combinations can be adopted. FIG. 9 is a diagram showing another example of the variation mode of the character E1 in the embodiment of the present invention.

  For example, in the above embodiment, an example in which one mutation mode is set for one site has been described, but the present invention is not limited to this as long as at least one mutation mode is set. That is, a plurality of mutation modes may be set for one site. For example, as shown in FIG. 9, when the right arm P1a of the character E1 is mutated, it is mutated into a sickle-shaped arm as shown in the above embodiment (after-mutation character E1B) and mutated into a chainsaw-shaped arm. The mode (post-mutation character E1B2) to be performed is set, and either (or not mutated) may be selected according to the conditions. In this case, the predetermined conditions include, for example, the probability of occurrence of each mutation, such as 55% mutation to a sickle arm, 15% mutation to a chainsaw arm, 30% without mutation, and the like. Depending on the situation, the probability of not mutating may be set, and the condition determination means 44 may perform a lottery process based on the set probability.

  Further, the site mutation means 45 may allow one site of the character to be mutated a plurality of times. For example, as shown in FIG. 9, when the head is mutated and the character E1D has a post-mutation head P3d that spits mucus from the tip of the head, and if a predetermined condition is satisfied for the head, The head may be mutated so that there are a plurality of heads (after the character E1D2 after mutation), or the neck may be long (not shown). Thereby, the combination of a variation | mutation aspect can be increased easily. In this case as well, the second mutation may be different from the second mutation mode based on the state of the character at the time of the first mutation, or a predetermined condition that must be satisfied for the mutation. May be different.

  Moreover, even if it is the variation | mutation of the same site | part, it is good also as changing a variation | mutation aspect according to the kind of damage. In this case, the character damage determination unit 43 not only determines the presence / absence and amount of damage for each part, but also determines the type of damage. The type of damage is set to be different depending on, for example, the type of player character (gender, physique, adult or child, etc.) and the type of weapon used in the attack. For example, in the character E1 shown in FIG. 9, when the arm portion is damaged by the gun, the arm portion is changed to a sickle character E1B, but when the same arm portion is damaged by the knife, It may be a post-mutation character E1B2 whose part is mutated in a chainsaw shape. At this time, if the character E1B2 is mutated due to damage caused by a knife, the amount of damage corresponding to the weapon may change in the character E1B2 after the mutation (for example, the damage caused by the knife is strong but the damage caused by the gun is weak). . Further, when the arm part is damaged by the male player character, the arm part is changed to a sickle-shaped character E1B, but when the female player character is damaged by the same arm part, the arm part is It may be a post-mutation character E1B2 that has been mutated into a chainsaw shape. The amount of damage may vary depending on the type of damage, and the presence or absence of mutation may be set depending on the type of damage (for example, there are weapons that can be mutated and weapons that cannot be mutated) Such). That is, the type of damage may be included in the predetermined condition. In this way, the character's action presentation can be diversified also by changing the mutation mode according to the condition on the attacking side.

  The site variation means 45 may vary the variation mode based on the character state. For example, as shown in FIG. 9, when the foot has already been mutated (in the character E1B), when the foot is mutated (when a predetermined condition necessary for the mutation is satisfied), the foot is If it has been transformed into a sickle-shaped foot (becomes character E1E2 after mutation) and has already been transformed into a chainsaw-shaped arm (in character E1B2), if the foot is mutated, the foot will be transformed into a wing. (It becomes after-mutation character E1E3). In addition, when the foot part is mutated after the sickle-shaped arm part is mutated, the foot part becomes a wing part (becomes the post-mutation character E1E shown in FIG. 4), while the foot part is mutated to the wing part. When the arm portion is mutated, the arm portion may become a chain saw-shaped arm portion (becomes the mutated character E1E3 shown in FIG. 9). The variation of the foot when the arm is not mutated may be different from these variations (the arm is not mutated or is one of the character states).

  As shown in FIG. 4, when the head is not mutated (pre-mutation character E1A), when the foot is mutated, the foot becomes a wing (becomes the mutated character E1C shown in FIG. 4). On the other hand, if the foot is changed after the head becomes a mutated head that discharges mucus from the tip (becomes the mutated character E1D), the foot becomes a chainsaw-like foot (see FIG. 9). It may be the character E1G) after the mutation. Thereby, the order of the parts where the player (player character) attacks the character E1 affects the progress of the game, and the game becomes more diversified.

  In addition, when a plurality of mutation modes are set for one part, the probability of changing to one of the plurality of mutation modes changes based on the character state (for example, in the above example, the character In E1B, the probability of mutating to a sickle-shaped foot is higher than the probability of mutating to a wing, and in character E1B2, the probability of mutating to a wing is higher than the probability of mutating to a sickle-shaped foot). . Of course, the present invention is not limited to this, and even if a plurality of mutation modes are set for one part, the mutation modes may not be changed based on the state of the character. For example, at a site where a plurality of mutation modes are set, any one of the mutation modes may be adopted at random.

  In addition, when a plurality of parts are mutated, the character performs different actions depending on the combination of the mutated parts (having different motion data or changing the priority of the motion data). It may be set. For example, in the post-mutation character E1F (FIG. 4) having a mutated posterior head that vomits mucus and a sickle-like posterior arm, an attack mode in which mucus is evacuated from the head while the player character is pierced with the sickle-like arm. In the character E1G (FIG. 9) having a mutated posterior head and a chainsaw-like mutated rear arm portion having mucus, and attacking with an arm portion on the chainsaw after the player character is stopped by the mucus discharged from the head In a character (not shown) having a morphological posterior head and a winged mutated foot that has a mode, the player character is stopped by the mucus that is spouted from the head, and the body hits from the sky It is good also as having the attack aspect by. Further, the head may have different attack modes according to the mutation modes of other parts (for example, a bite attack is performed instead of spitting mucus).

  Further, when a plurality of parts are mutated, the character's action mode (priority of action and attack mode) may be different depending on the order of the mutated part. For example, in a post-mutation character E1F (FIG. 4) having a mutagenic head and a sickle-shaped rear arm, when the head is first mutated and then the arm is mutated (through the post-mutation character E1D ), The priority for using motion data having an attack mode of attacking with a sickle-like arm after stopping the player character with mucus spouted from the head is increased, while the arm portion has been mutated first Later, when the head is mutated (after passing through the mutated character E1B), priority is given to using motion data having an attack mode of spitting mucus from the head while the player character is pierced with a sickle-like arm. The degree may be higher.

  Moreover, in the said embodiment, although the condition determination means 44 is supposed to perform the condition determination of variation | mutation triggered by having received the damage to the predetermined site | part of the character E1, this invention is not limited to this, The presence or absence of damage Regardless of the condition, the condition may be determined. In this case, it is good also as changing the said character according to the change of the environment where a character exists. For example, the character may be mutated according to the time in the game space (for example, when the sun goes down and at night), or a plurality of characters configured as enemy characters are arranged in a predetermined area, When the number of characters in the area is equal to or less than a predetermined number (for example, when the player character defeats a predetermined number of characters), the remaining characters may be mutated. Further, the enemy character may be changed according to the status of the player character. For example, the enemy character may be mutated when the physical strength of the player character falls below a predetermined value.

  Moreover, in the said embodiment, although the character E1 which produces a part variation | transformation action was demonstrated as an enemy character (non-player character), it is good also as a part variation | movement action being produced in a player character. The present invention can also be applied to characters other than human characters (for example, monster type, robot type, etc.).

  Further, in the game space, a character to be mutated and a character not to be mutated may coexist, or a portion to be mutated may be varied depending on the type of character. Moreover, even if it is the same kind of character, you may vary the site | part which each character changes. At this time, for example, when a character is generated in the game space, a portion where the character is mutated may be determined at random, or a portion where the character is mutated may be set in advance for each character and each stage.

  Further, in the above-described embodiment, the mutation occurs in three parts (the right arm part P1a → P1b, the foot part P2a → P2c, the head part P3a → P3d in FIG. 4) among the plurality of parts constituting the character E1. Although it is set, the present invention is not limited to this, and may be set so that a mutation occurs in at least two of the plurality of parts constituting the character. Of course, it may be set so that a variation occurs in all of a plurality of parts constituting the character.

  In the above description, the case where one player plays an offline game has been exemplified. However, in the present invention, a plurality of players cause their player characters to appear in the same game space and act in cooperation with each other. It can also be applied to online games.

  Further, although the stationary game apparatus has been described in the present embodiment, the present invention can be preferably applied to computers such as portable game apparatuses, mobile phones, and personal computers.

  INDUSTRIAL APPLICABILITY The present invention is useful for diversifying character action effects during a game in a game program and a game device.
