[First Embodiment]
Hereinafter, a video game processing system 100 to which an image processing apparatus according to an embodiment of the present invention is applied will be described. FIG. 1 is a block diagram showing an example of the configuration of a video game processing system 100 according to an embodiment of the present invention. As shown in FIG. 1, the video game processing system 100 includes a server 10 and user terminals 20, 201 to 20N (N is an arbitrary integer) used by a user of the video game processing system. Note that the configuration of the video game processing system 100 is not limited thereto, and a single user terminal may be used by a plurality of users, or a configuration including a plurality of servers.

  The server 10 and the plurality of user terminals 20 and 201 to 20N are each connected to a communication network 30 such as the Internet. Although not shown, the plurality of user terminals 20 and 201 to 20N are connected to the communication network 30 by performing data communication with a base station managed by a communication provider through a wireless communication line.

  The video game processing system 100 includes the server 10 and the plurality of user terminals 20 and 201 to 20N, thereby realizing various functions for executing various processes according to user operations.

  The server 10 is managed by an administrator of the video game processing system 100, and has various functions for providing information related to various processes to the plurality of user terminals 20, 201 to 20N. In this example, the server 10 includes an information processing apparatus such as a WWW server, and includes a storage medium that stores various types of information. The server 10 includes a general configuration for performing various processes as a computer, such as a control unit and a communication unit, but a description thereof is omitted here. Further, in the video game processing system 100, it is preferable that the server 10 manages various information from the viewpoint of reducing the processing load on each of the plurality of user terminals 20, 201 to 20N. However, the memory | storage part which memorize | stores various information should just be provided with the memory area in the state which the server 10 can access, for example, may be set as the structure which has an exclusive memory area outside the server 10. FIG.

  Each of the plurality of user terminals 20, 201 to 20N is managed by a user, and is a communication terminal capable of playing a network distribution type game such as a mobile phone terminal, a PDA (Personal Digital Assistants), or a portable game device. Composed. The configuration of the user terminal that can be included in the video game processing system 100 is not limited to the above-described example, and may be any configuration as long as the user can recognize the video game. Other examples of user terminal configurations include so-called wearable devices such as smart watches, and combinations of wearable devices and communication terminals.

  Each of the plurality of user terminals 20 and 201 to 20N is connected to the communication network 30 and communicates with the server 10 to execute various processes (for example, a browser screen or a screen corresponding to coordinates). A display device for displaying a game screen) and software. Each of the plurality of user terminals 20 and 201 to 20N may be configured to be able to directly communicate with each other without using the server 10.

  In the process of performing the video game process, the server 10 appropriately transmits the process to the user terminal 20, and the user terminal 20 displays a game screen based on the content of the received process on the display device. It shall be displayed on the display screen. The game screen may be generated on the server 10 side or on the user terminal 20 side.

  Here, the game screen means a screen representing a virtual space (or game space). In this example, various elements constituting the game screen may be referred to as images. The configuration of the game screen is not particularly limited as long as the user can recognize the situation of the video game.

  Displaying the game screen on the display screen of the display device means that the game screen is output to the display device provided in the user terminal 20 or the like by communication using the communication network 30. An example of a configuration for displaying a game screen on a display device is a configuration in which information generated on the server side (output information) is transmitted to the terminal side. Note that the configuration of the output information is not particularly limited, and may be, for example, information obtained by compressing an image, or information for generating an image on the terminal side. An example of information obtained by compressing an image is one used in a cloud game (for example, MPEG). Information for generating an image on the terminal side includes information used in an online game (for example, object position information).

  FIG. 2 is a block diagram illustrating a configuration of the server 10 </ b> A that is an example of the configuration of the server 10. As illustrated in FIG. 2, the server 10 </ b> A includes at least a specifying unit 11, a change amount calculating unit 12, and an adding unit 13.

  The specifying unit 11 has a function of specifying a change factor of an external part set in an object when an operation instruction to the object is received. The operation instruction to the object can be rephrased as an instruction to calculate the motion of the object.

  An object is an object that exists in a video game. The target object of this example is a thing that can execute some kind of operation. The objects include, for example, player characters and other user operation target objects, other user operation target objects, non-player character objects that act without user operation, and the like. Regarding how to represent an object in a video game, it may be represented by a 3D polygon or a 2D animation, and any representation format may be used as long as the object can be represented.

  An external part set for an object refers to a part constituting the appearance of the object. The object is assumed to be composed of a skeleton (also referred to as a bone) for expressing the basic form of the object and an external part fitted into the skeleton. The external parts are merely examples, but parts that represent the muscles of the player character or non-player character as an object, skin texture including fat, and clothes worn by the player character or non-player character as an object. And parts for expressing animal hair as an object. This example is characterized in that an object is composed of a part of an object that does not change due to a change factor and a part of an outer shape part that changes according to the change factor. Of course, external parts that are not affected by the change factors can also be adopted.

  The change factor of the external part is a factor in the virtual space that occurs around the object and affects the external part. As an example, wind generated in a virtual space, vibration, air resistance when an object freely falls, and the like can be cited. The specifying unit 11 specifies whether or not there is a change factor existing in the virtual space.

  Motion refers to a series of actions that are executed by an object. As the motion, for example, various actions such as “walking”, “running”, “bowing”, “waving hands”, “dancing”, “doing shadow boxing” can be considered. The range of motions to be executed by the object with one motion command may be any, but motions that change at least over a plurality of frames are assumed as motions here.

  An operation instruction to an object is an instruction that serves as a trigger for causing the object to perform a motion. The operation instruction to this object may be an input operation input via the user terminal 20 by a user playing the video game, or an instruction triggered by the establishment of some flag in the video game. Also good.

  Motion calculation means calculating data representing the state of an object to be output on the game screen based on an operation instruction to the object. The motion calculation may be performed in real time according to the motion request for the object, or may be read from the motion previously stored in the storage means corresponding to the motion request for the object. Good.

  The change amount calculation unit 12 stores a reference motion composed of an object and an external part set to the object, and indicates a state after the change of the external part when a change factor of the external part is added to the reference motion. With reference to a storage unit that stores the changed motion for each of a plurality of change factors, a function of calculating a difference between the change motion corresponding to the specified change factor and a reference motion to obtain a change amount of the external part is provided.

  The reference motion is motion data serving as a reference representing an operation in a state where there is no change factor related to the object set with the external part. In addition, change motion is motion data that represents the operation in a state where a change factor related to the object set with the external part is added, and represents motion data that represents the same operation as the reference motion for which a difference is to be obtained. Say. The reference motion and the change motion are stored in advance in order to calculate only the amount of change when the external part changes due to the change factor. Both the reference motion and the change motion of the same operation are stored together. By taking the difference, only the amount of change due to the change factor can be calculated by the difference. In other words, as long as the amount of change can be calculated, the behavior of the reference motion and the change motion can be anything, and if the change state of the outer part can be expressed in the change motion, it can stand still in a standing posture. May be the data. The change motion is prepared for each of a plurality of change factors and stored in the storage means. For example, when the change factor is a wind in the virtual space, a change motion corresponding to each of a plurality of wind directions is created and stored in advance.

  The adding unit 13 has a function of calculating the motion of the motion state of the object in a state where there is no change factor, and adding the change amount calculated by the change amount calculating unit 12 to the calculation result. Even when the specifying unit 11 specifies that there is a change factor, the adding unit 13 calculates the motion of the motion state of the object when there is no change factor. By adding the amount of change calculated by the amount of change calculation unit 12, the motion in the operation state after the change of the external part due to the change factor is reflected is generated.

  FIG. 3 is a flowchart illustrating an example of game processing executed by the video game processing system 100. Hereinafter, a case where the server 10A and the user terminal 20 (terminal 20) execute game processing will be described as an example.

  The game process is started, for example, in a state where a motion can be executed on the object. After the game process is started, for example, when an operation instruction is given to the object at the user terminal 20, the user terminal 20 transmits to the server 10A that the operation instruction has been made (step S11). The server 10A specifies a change factor in the virtual space when the operation instruction is given (step S12). When there is a change factor, the server 10A reads the change motion and the reference motion corresponding to the specified change factor from the storage unit, calculates the difference between the read change motion and the reference motion, and calculates the amount of change of the outer part. (Step S13). Then, the server 10A calculates the motion of the operation state of the object in a state where there is no change factor, and adds the calculated change amount to the calculation result, thereby reflecting the change in the external part due to the change factor. After that, the motion in the operating state is obtained (step S14), and the process is terminated.

  FIG. 4 is a flowchart showing an example of the operation on the server 10A side in the game process. Here, the operation of the server 10A in the video game processing system 100 will be described.

  When an action instruction is given to the object, the server 10A specifies a change factor in the virtual space when the action instruction is given (step S101). When there is a change factor, the server 10A reads the change motion and the reference motion corresponding to the specified change factor from the storage unit, calculates the difference between the read change motion and the reference motion, and calculates the amount of change of the outer part. (Step S102). Then, the server 10A calculates the motion of the operation state of the object in a state where there is no change factor, and adds the calculated change amount to the calculation result, thereby reflecting the change in the external part due to the change factor. After that, the motion in the operating state is obtained (step S103), and the process ends.

  FIG. 5 is a flowchart illustrating an example of an operation on the user terminal 20 side when the user terminal 20 executes a game process. Hereinafter, a case where the user terminal 20 executes the game process alone will be described as an example. Note that the configuration of the user terminal 20 has the same functions as the configuration of the server 10 except that various types of information are received from the server 10, and thus description thereof is omitted from the viewpoint of avoiding redundant explanation.

  When a motion instruction is given to the object, the user terminal 20 specifies a change factor in the virtual space when the motion instruction is given (step S201). When there is a change factor, the user terminal 20 reads the change motion and the reference motion corresponding to the specified change factor from the storage unit, calculates the difference between the read change motion and the reference motion, and calculates the change amount of the outer part. Calculate (step S202). Then, the user terminal 20 calculates the motion of the operation state of the object in a state where there is no change factor, and adds the calculated change amount to the calculation result, thereby reflecting the change in the external part due to the change factor. The motion of the operation state after being obtained is obtained (step S203), and the process is terminated.

  As described above, as one aspect of the first embodiment, the server 10A functioning as an image processing apparatus having a function of generating the motion of an object by controlling the operation of the object in the virtual space includes the specifying unit 11, a change amount calculation unit 12, and an addition unit 13, a change factor is specified when an operation instruction to the object is received, and a change motion corresponding to the specified change factor is determined by referring to the storage unit Since the difference from the reference motion is calculated to determine the amount of change in the outer part, the motion of the object's operation state without the change factor is calculated, and the change amount is added to the calculation result. The influence of the change factor on the outer shape part of the character can be appropriately expressed while reducing the processing load.

  In other words, when trying to calculate in real time the change state of the external parts due to the change factors existing in the virtual space, the processing hardware is subjected to a considerable processing load, and the processing load varies greatly depending on the situation. For this reason, there is a possibility that the behavior of the hardware may become unstable due to the physical calculation, but the change state of the external part is not calculated in real time as in this example, but corresponds to the change factor stored in the storage means. It is possible to reduce the processing load by processing the change state of the external part using the change amount due to the difference between the change motion and the reference motion. In addition, since the divergence that occurs in the physical calculation does not occur, the quality assurance cost can be reduced.

[Second Embodiment]
FIG. 6 is a block diagram illustrating a configuration of a server 10B that is an example of a configuration of the server 10. As illustrated in FIG. As illustrated in FIG. 6, the server 10 </ b> B includes at least a specifying unit 11, a change amount calculating unit 12 </ b> B, and an adding unit 13.

  The change amount calculation unit 12B stores the reference motion composed of the object and the external part set to the object, and also represents the state after the change of the external part when a change factor of the external part is added to the reference motion. A function to obtain the amount of change of the external part by calculating the difference between the change motion corresponding to the specified change factor and the reference motion by referring to the storage means that stores the changed motion for each of the change factors In addition, when the change factor specified by the specifying unit 11 does not match the change factor of the change motion stored for each change factor in the storage unit, two or more change motions are blended and specified by the specifying unit 11 It has a function of calculating a difference from a reference motion after approximately calculating a change motion in the case of a change factor.

  The case where the specified change factor does not match the change factor of the change motion stored for each change factor in the storage means means that the change motion for the same condition as the specified change factor is not stored in the storage means. . For example, when the change factor is a wind in the virtual space, if the change factor specified by the specifying unit 11 is a northeast wind, the change motions of the north wind and the east wind are stored in the storage means, This corresponds to the situation in which the change motion that directly corresponds to the northeast wind is not stored.

  Blending motion refers to generating a new motion information by mixing a plurality of motions at an arbitrary mixing ratio. In addition, for the mixing process of a plurality of motions, since a known motion blending method that performs a process of interpolating the posture of an operation for each time frame by synchronizing a plurality of motions is used, detailed description thereof is omitted here. . In this example, a known motion blending method is used when approximately calculating a change motion in the case of a change factor specified by blending two or more change motions stored in the storage means. As an example, when the change factor is northeast wind, the change motion of north wind and east wind is stored in the storage means, but the change motion corresponding directly to the northeast wind is not stored. If the change motion of the north wind and the change motion of the east wind are mixed at a mixing ratio of 1: 1, the change motion corresponding to the northeast wind can be calculated approximately. Further, when the change factor is the north-northeast wind, the change motion corresponding to the north-northeast wind can be calculated by mixing the north wind change motion and the east wind change motion in a mixing ratio of 3: 1.

  FIG. 7 is a flowchart showing an example of the operation on the server 10B side in the game process. Here, the operation of the server 10B in the video game processing system 100 will be described.

  When an action instruction is given to the object, the server 10B specifies a change factor in the virtual space when the action instruction is given (step S301). When there is a change factor, the server 10B reads the change motion and the reference motion corresponding to the specified change factor from the storage unit, calculates the difference between the read change motion and the reference motion, and calculates the change amount of the external part. However, at this time, if the change motion that directly corresponds to the specified change factor is not stored in the storage means, the change motion corresponding to the specified change factor is approximated by blending two or more change motions. After the calculation, the change amount is calculated (step S302). Then, the server 10B calculates the motion of the operation state of the object in a state where there is no change factor, and adds the calculated change amount to the calculation result, thereby reflecting the change in the external part due to the change factor. After that, the motion in the operating state is obtained (step S303), and the process ends.

  As described above, as one aspect of the second embodiment, the server 10B having a function of controlling the progress of the video game according to the user's operation includes the specifying unit 11, the change amount calculating unit 12B, 2 or more when the change factor specified by the specifying unit 11 does not match the change factor of the change motion stored for each change factor in the storage unit in the change amount calculation unit 12B. Since the difference motion with the reference motion is calculated after the change motion of the specified change factor is approximately calculated after blending the change motions, the number of change motions to be stored in the storage means increases. It is possible to generate a motion in which a change due to the specified change factor is appropriately reflected while preventing this.

  In other words, if it is necessary to prepare and store change motions on a one-to-one basis for all the change factors, the amount of data may become enormous and the storage capacity may be compressed. If the change motion corresponding to the change factor is calculated approximately using the change motion, the change motion corresponding to the change factor can be thinned out, so the amount of data can be reduced. .

[Third Embodiment]
FIG. 8 is a block diagram illustrating a configuration of a server 10 </ b> C that is an example of a configuration of the server 10. As illustrated in FIG. 8, the server 10 </ b> C includes at least a specifying unit 11, a change amount calculating unit 12 </ b> C, and an adding unit 13.

  The change amount calculation unit 12C stores the reference motion composed of the object and the external part set to the object, and also represents the state after the change of the external part when the change factor of the external part is added to the reference motion. A function to obtain the amount of change of the external part by calculating the difference between the change motion corresponding to the specified change factor and the reference motion by referring to the storage means that stores the changed motion for each of the change factors Furthermore, when a request for an influence speed different from the change factor stored in the storage unit is made with respect to the influence rate of the change factor specified by the specifying unit 11, the change motion corresponding to the change factor stored in the storage unit A function that calculates the difference after changing the playback speed according to the request of the influence speed of the change factor for both the standard motion It has.

  The influence speed of the change factor is one of the parameters representing the influence of the force acting on the external part from the change factor. When expressing the force acting on the outer part from the change factor, it is natural that a parameter of the magnitude of the force is necessary, but when expressing the change of the outer part by periodicity, the periodicity is necessary. It is conceivable to manage an interval of one cycle of a change as a parameter relating to the influence speed. For example, when expressing that the cloak's foot sways due to wind in the virtual space, the amplitude of the cloak's sway is affected by the magnitude of the force from the change factor, but when expressing the cloak's sway, There is a case where the cloak of the cloak is expressed by periodically changing the skirt so as to greatly rise or to return to the original position. It is also possible to express the cloak fluctuation by changing the parameter of the magnitude of the force from the change factor over time, but the magnitude of the force from the change factor is constant at a predetermined value while maintaining a predetermined amplitude range and In some cases, the influence of a change factor is expressed by swinging the bottom of the cape at a predetermined period. In the case of such a periodic change, the influence from the change factor can be changed and expressed by shortening or lengthening the period. In this case, the length of the cycle is the influence speed of the change factor.

  When the influence speed different from the change factor stored in the storage means is requested for the influence speed of the specified change factor, the influence speed parameter requested by the change factor specified by the specifying unit 11 is directly set. This refers to a situation in which the corresponding change motion is not stored in the storage means. In order to respond to the request for the influence speed, the change amount calculation unit 12C sets the reproduction speed according to the request for the influence speed of the change factor for both the change motion and the reference motion that are different only in the specified change factor and the influence speed. The difference is calculated after changing.

  FIG. 9 is a flowchart showing an example of the operation on the server 10C side in the game process. Here, the operation of the server 10C in the video game processing system 100 will be described.

  In the server 10C, when an action instruction is given to an object, a change factor in the virtual space when the action instruction is given is specified (step S401). If there is a change factor, the server 10C reads the change motion and the reference motion corresponding to the specified change factor from the storage unit, calculates the difference between the read change motion and the reference motion, and calculates the change amount of the outer part. However, at this time, if the change motion that directly corresponds to the state of the parameter of the influence speed requested by the specified change factor is not stored in the storage means, the change motion and the reference differing only in the specified change factor and the influence speed. For both motions, after changing the reproduction speed in response to the request for the influence speed of the change factor, the difference is calculated to calculate the amount of change (step S402). Then, the server 10C calculates the motion of the operation state of the object in a state where there is no change factor, and adds the calculated change amount to the calculation result, thereby reflecting the change in the external part due to the change factor. After that, the motion in the operating state is obtained (step S403), and the process is terminated.

  As described above, as one aspect of the third embodiment, the server 10C having a function of controlling the progress of the video game according to the user's operation includes the specifying unit 11, the change amount calculating unit 12C, An adder 13, and in the change amount calculator 12 </ b> C, an influence speed different from the change factor stored in the storage unit is requested for the influence speed of the change factor specified by the specifying unit 11. For both the change motion corresponding to the change factor stored in the means and the reference motion, the difference is calculated after changing the playback speed in response to the request for the influence speed of the change factor. While preventing the number of change motions to be increased from increasing, it is possible to generate a motion in which changes due to the specified change factors are appropriately reflected.

  In other words, if you try to prepare and store change motions one-on-one for the influence speed of all the change factors, there is a risk that the amount of data will be enormous and it will squeeze the storage capacity, but as in this example, By changing the playback speed for the change motion and the reference motion that differ only in the influence speed stored in the storage means and calculating the amount of change, it is possible to deal with all the subtle changes in the influence speed. Since there is no need to prepare a change motion and store it in the storage means, the data amount can be reduced.

FIG. 10 is a block diagram illustrating a configuration of a server 10D that is an example of a configuration of the server 10 (see FIG. 1). As illustrated in FIG. 10, the server 10 </ b> D includes at least a specifying unit 11, a change amount calculating unit 12 </ b> D, and an adding unit 13.

  The specifying unit 11 has a function of specifying a change factor of an external part set in an object when an operation instruction to the object is received.

  The change amount calculation unit 12D has a function of obtaining the change amount of the outer part with reference to information stored in a predetermined storage unit. In this example, the predetermined storage means stores a reference motion composed of an object and an external part set for the object. In addition, the predetermined storage means stores, for each of a plurality of change factors, a change motion representing a state after the change of the external part when the external part change factor is added to the reference motion. Then, the change amount calculator 12D calculates the difference between the change motion corresponding to the specified change factor and the reference motion to obtain the change amount of the outer part.

  Further, the change amount calculation unit 12D requests the influence amount of the change factor when the influence amount different from the change factor stored in the storage unit is requested for the magnitude of the influence amount of the change factor specified by the specifying unit 11. It has a function of multiplying a predetermined magnification according to the size of. In this example, the change amount calculation unit 12D refers to the storage unit to calculate the difference between the change motion corresponding to the change factor and the reference motion to obtain the change amount of the outer part, and for the obtained change amount Multiply by a predetermined magnification according to the magnitude of the request for the influence amount of the change factor.

  The magnitude of the influence amount of the change factor means the magnitude of the force acting on the outer shape part from the change factor, and is one of the parameters representing the influence force from the change factor. When expressing the force acting on the external part from the change factor, a parameter for the magnitude of the force is necessary, but it is conceivable to manage the magnitude of the magnitude of the force as a comparable parameter. For example, when expressing that the skirt of the cloak sways due to the wind in the virtual space, the amplitude of the cloak sway is affected by the magnitude of the force from the change factor. For example, even if the winds are from the same wind direction, the cloak greatly sways in the case of strong winds, and the cloak slightly sways in the case of light winds. The change amount calculation unit 12D obtains the change amount by taking the difference between the change motion and the reference motion, and multiplies the change amount by a predetermined magnification to express the magnitude of the influence amount of the change factor. Here, the predetermined magnification is obtained by comparing the parameter indicating the magnitude of the influence amount of the change motion stored in the storage unit and the parameter indicating the magnitude of the influence amount required for the change factor specified by the specifying unit 11. Is to be calculated.

  The adding unit 13 has a function of calculating the motion of the motion state of the object in a state where there is no change factor, and adding the change amount calculated by the change amount calculating unit 12 to the calculation result. Even when the specifying unit 11 specifies that there is a change factor, the adding unit 13 calculates the motion of the motion state of the object when there is no change factor. By adding the amount of change calculated by the amount of change calculation unit 12, the motion in the operation state after the change of the external part due to the change factor is reflected is generated.

  Note that the function of calculating the amount of change by multiplying the predetermined factor according to the magnitude of the request for the amount of influence of the change factor described as a function in the amount-of-change calculator 12D may be a function executed by the adder 13. That is, the change amount calculation unit 12D calculates the change amount without multiplying by a predetermined magnification, and the addition unit 13 obtains the change amount calculation unit 12D for the motion of the object in the state where there is no change factor. A value obtained by multiplying the change amount by a predetermined magnification may be added. The same effect can be obtained when the multiplication processing of the predetermined magnification is executed by the change amount calculation unit 12D or the addition unit 13.

  FIG. 11 is a flowchart showing an example of the operation on the server 10D side in the game process. Here, the operation of the server 10D in the video game processing system 100 will be described.

  When an action instruction is given to the object, the server 10D specifies a change factor in the virtual space when the action instruction is given (step S501). When there is a change factor, the server 10D reads the change motion and the reference motion corresponding to the specified change factor from the storage unit, calculates the difference between the read change motion and the reference motion, and calculates the amount of change of the outer part. To do. At this time, if the change motion that directly corresponds to the parameter related to the magnitude of the influence amount requested by the specified change factor is not stored in the storage means, the change motion that differs only in the magnitude of the influence amount from the specified change factor and A difference is calculated for the reference motion, and a change amount is calculated by multiplying the difference by a predetermined magnification corresponding to the magnitude of the request for the influence amount of the change factor (step S502). Then, the server 10D calculates the motion of the operation state of the object in a state where there is no change factor, and adds the calculated change amount to the calculation result, thereby reflecting the change in the external part due to the change factor. After that, the motion in the operating state is obtained (step S503), and the process ends.

  FIG. 12 is an explanatory diagram for explaining a change amount calculation function in the game process corresponding to at least one of the embodiments of the present invention. 12A is an explanatory diagram illustrating an example of a reference motion stored by the storage unit, and FIG. 12B is an explanatory diagram illustrating an example of a change motion stored by the storage unit. The reference motion and the change motion shown in FIGS. 12A and 12B have the same posture in the skeleton data of the object, but there is a difference in whether or not there is a change factor with respect to the external part. is there. Specifically, the reference motion shown in FIG. 12A is the motion of the object in a windless state where there is no change factor, and the change motion shown in FIG. 12B is the right side surface direction of the object as the change factor. Is the motion of the object in the presence of wind from. In the change motion as shown in FIG. 12B, the type of the change factor, the magnitude of the influence amount of the change factor, the influence speed of the change factor, etc. are set, and the change amount is set based on these settings. Decide which change motion to use in the calculation. When the change motion of FIG. 12B is selected for calculating the change amount, the change amount is calculated by taking a difference from the reference motion of FIG. At that time, when the parameter of the influence amount of the change factor is different from the required value in the change factor specified by the specifying unit 11, the change amount is multiplied by a predetermined magnification corresponding to the required influence amount. To do.

  FIG. 13 is an explanatory diagram for explaining an addition function in the game processing corresponding to at least one of the embodiments of the present invention. FIG. 13A is an explanatory diagram illustrating an example of a motion in a state where there is no influence of a change factor, and FIG. 13B illustrates an example of a motion after adding a change amount to the motion of FIG. It is explanatory drawing represented. First, the adder 13 calculates a motion in a state without the influence of the change factor as shown in FIG. 13A regardless of the presence or absence of the change factor. Then, a change amount calculated by taking a difference using the reference motion and the change motion as shown in FIGS. 12A and 12B is added to the motion without the influence of the calculated change factor. Thus, a motion reflecting the influence of the change factor as shown in FIG. 13B is generated.

  As described above, as one aspect of the fourth embodiment, the server 10D having a function of controlling the progress of the video game according to the user's operation includes the specifying unit 11, the change amount calculating unit 12D, When the change amount calculation unit 12D includes the addition unit 13, the influence amount different from the change factor stored in the storage unit is requested for the magnitude of the influence amount of the change factor specified by the specifying unit 11. Referring to the storage means, the difference between the change motion corresponding to the change factor and the reference motion is calculated, and the obtained difference is multiplied by a predetermined magnification according to the magnitude of the request for the influence amount of the change factor. Since the amount of change in the external parts is calculated, the motion that properly reflects the change due to the specified change factor while preventing the number of change motions to be stored in the storage means from increasing. It is possible to generate.

  In other words, if the change motions are always prepared in a one-to-one manner and stored with respect to the magnitude of the influence amount of all the change factors, the amount of data may become enormous and the storage capacity may be compressed. If the change rate is calculated after changing the playback speed for the change motion and the reference motion that differ only in the magnitude of the impact amount from the requested change factor, the change in the impact speed will be fine. Since it is not necessary to prepare a change motion corresponding to all of the above and store it in the storage means, the data amount can be reduced.

  In the first to fourth embodiments described above, when the motion is calculated by the adding unit 13, it is common to execute the calculation process in units of image frames to be output to the game screen. On the other hand, the reference motion and the change motion stored by the storage means can be composed of a single frame, but it is composed of a plurality of frames in order to express the change of the external part as a change with time. In this case, it is possible to obtain information for a plurality of frames for the amount of change including the difference between the reference motion and the change motion. That is, when the addition unit 13 calculates the motion and adds the amount of change, the amount of change added to the motion while calculating the motion in units of frames is calculated based on the amount of change calculated for a plurality of frames. By sequentially adding to the motion calculated using the frame, it is possible to express the change in the external part as a change with time in the generated motion.

  As described above, one or more deficiencies are solved by each embodiment of the present application. In addition, the effect by each embodiment is an example of a non-limiting effect or effect.

  In each of the above-described embodiments, the plurality of user terminals 20 and 201 to 20N and the server 10 are configured according to various control programs (for example, video game processing programs) stored in a storage device included therein. Execute the process.

  The configuration of the system 100 is not limited to the configuration described as an example of each embodiment described above, and for example, the server 10 may execute a part or all of the processing described as processing executed by the user terminal. A part or all of the processes described as the processes executed by the server 10 may be executed by any one of the plurality of user terminals 20 and 201 to 20N (for example, the user terminal 20). Moreover, it is good also as a structure with which some of the some memory | storage parts with which the server 10 is provided are equipped with either of the several user terminals 20, 201-20N. That is, a configuration may be adopted in which one of the user terminal 20 and the server 10 in the system 100 has a part or all of the functions of the other one.

  Moreover, it is good also as a structure which a program implement | achieves a part or all of the function demonstrated as an example of each embodiment mentioned above to the apparatus single-piece | unit which does not contain a communication network.

Examples of specific processing include determination processing and information update processing. Examples of various progress or changes that may occur in a video game include time progress, changes in game element values, update of a specific status or flag, or operation input by a user.
