Description
Technical Field
The invention relates to the technical field of computers, in particular to a method and a device for realizing local animation of a role, a storage medium and an electronic device.
Background
In the related art, a character in a game needs to perform different actions at different positions (upper and lower body) under a specific state, for example, archery during running, a pull bow action is required for the upper body, and a running action is required for the lower body.
In the scheme of the related technology, the upper body animation and the lower body animation can be separated by manufacturing a Mask of the upper body skeleton and binding the Mask to the upper body Layer of Animator Controller and then matching with the whole body animation Layer. Because the animation operation is in the part space, the Rotation curves recorded in the animation are all relative to the movement of the father node, namely, even if the Spine (Bip 001 Spine) does not move, the father node pelvis (Bip 001 Pelvis) of the animation is swayed, the Bip001Spine skeleton still follows the swaying, and finally the upper body is swayed back and forth along the waist. For example, the upper body can rock along with the waist of the user during running, so that the problem that the upper body swings back and forth during running is solved, and the stable representation effect of the upper body cannot be realized.
In view of the above problems in the related art, no effective solution has been found yet.

The transition of the upper body and the lower body can be smoothed through a plurality of bones, the upper body and the lower body can be mixed in proportion between the Parent space animation and the Root space animation, the upper body animation and the lower body animation which are more stable and natural are obtained, the effect is better, the existing animations can be spliced, and the development cost is saved.
