The skeletal offset data for a single skeletal animation frame includes positional offset information, scaling offset information, and rotational offset information for each character skeletal node of the generic character relative to a corresponding parent skeletal node within the game skeletal animation frame.
In this embodiment, the processor 12 may be an integrated circuit chip having signal processing capabilities.

In this embodiment, the character animation sharing apparatus 100 includes at least one software function module that can be stored in the memory 11 in the form of software or firmware or solidified in the operating system of the computer device 10. The processor 12 may be used to execute executable modules stored by the memory 11, such as software functional modules and computer programs included in the character animation sharing device 100. The computer device 10 can enable different game characters with similar character skeleton topological structures to generate adaptive action posture skeleton data through the skeleton animation sharing device 100, and does not need to create proper skeleton animation for different game characters, so that the manual creation workload of the character skeleton animation is greatly reduced, and the redundancy condition of animation data is improved.

Referring to fig. 2, fig. 2 is a flowchart illustrating a role animation sharing method according to an embodiment of the present application. In the embodiment of the present application, the character animation sharing method may include steps S210 to S220.
Step S210, obtaining original posture skeleton data of the character to be processed and preset skeleton animation of the universal character matched with the action of the target character, wherein the respective character skeleton topological structures of the character to be processed and the universal character are similar.
In this embodiment, the target character action is a game action required to be exhibited by the character to be processed, the original posture bone data is used to describe a bone distribution condition of the character to be processed when the character to be processed is in an original posture, and the original posture bone data includes original position information, original scaling information, and original rotation information of each character bone node of the character to be processed relative to a parent bone node in the original posture. The original postures of the to-be-processed role and the corresponding general role can be the same or different, and the original postures of different to-be-processed roles can be the same or different, for example, the original postures of a monkey role and a character role with similar skeleton topological structures are respectively in a stooping state and a standing state. Meanwhile, the node identifier of each role skeleton node in the to-be-processed role may be the same as or different from the node identifier of the role skeleton node with the same functional effect in the general role, for example, the node identifier of the role skeleton node corresponding to the left femur in the to-be-processed role may be a, and the node identifier of the role skeleton node corresponding to the left femur in the general role may be a or B.
And step S220, carrying out bone posture adaptation processing on the character to be processed according to the original posture bone data of the character to be processed on the basis of the pre-configured bone animation to obtain action posture bone data of the character to be processed, wherein the action posture bone data corresponds to the action of the target character.
In this embodiment, after the computer device 10 determines the to-be-processed character and the general character having similar character skeleton topology structures, the bone posture adaptation adjustment may be performed with reference to the original posture skeleton data of the to-be-processed character on the basis of the pre-configured skeleton animation of the general character related to the target character action, so as to obtain the action posture skeleton data related to the target character action, which is adapted to the to-be-processed character.
Therefore, by executing the steps S210 and S220, different game characters having similar character skeleton topologies can generate adaptive motion posture skeleton data by sharing the skeleton animation of a general character also having a similar character skeleton topology, and it is not necessary to create an appropriate skeleton animation for different game characters individually, so as to greatly reduce the manual creation workload of the character skeleton animation and improve the redundancy of animation data.

In this embodiment, each piece of target pose bone data in the motion pose bone data corresponds to one bone animation frame of the pre-configured bone animation, and the total number of pieces of target pose bone data in the motion pose bone data is consistent with the total number of bone animation frames in the pre-configured bone animation. The computer device 10 may perform bone posture shift on bone shift data representing a bone posture of the character in each bone animation frame of the pre-configured bone animation by using the character height ratio and the original posture bone data of the character to be processed, to obtain target posture bone data corresponding to each bone animation frame of the character to be processed in the action posture bone data, so as to ensure that the finally constructed action posture bone data is substantially completely matched with the character to be processed.
Therefore, by executing the substep S221 and the substep S222, the motion posture skeleton data related to the motion of the target character, which is completely matched with the character to be processed and has a similar topological structure with the character skeleton, is constructed by effectively using the skeleton animation of the universal character, so that the redundancy condition of the animation data is improved.

And a substep S2221 of multiplying the position offset information of the target skeleton node which is matched with the role skeleton node in function in the skeleton offset data of the skeleton animation frame by the height ratio of the role to each role skeleton node of the universal role to obtain the position translation amount of the corresponding role skeleton node of the role to be processed.
And a substep S2222 of, for each role skeleton node of the role to be processed, performing position translation processing on the original position information corresponding to the role skeleton node in the original posture skeleton data according to the calculated position translation amount of the role skeleton node to obtain target position information corresponding to the role skeleton node in the target posture skeleton data.
In this embodiment, when constructing the target posture bone data representing a certain motion posture of the motion posture bone data, it is necessary to select the bone offset data of the corresponding bone animation frame in the pre-configured bone animation for performing the related transformation. The bone offset data corresponding to a single bone animation frame includes position offset information of each character bone node of the universal character relative to a parent bone node in the bone animation frame, the original posture bone data includes original position information of each character bone node of the character to be processed relative to the parent bone node in an original posture, and at this time, target position information of each character bone node of the character to be processed relative to the parent bone node in target posture bone data representing a certain action posture included in corresponding action posture bone data can be obtained by executing the substep S2221 and the substep S2222, so as to determine a bone position distribution condition of the character to be processed when a single action posture of a target character action is maintained.
