AnimationMixer
Player for animations on a particular object in the scene.
This class manages animation playback for a specific object, providing
methods to control animation timing, playback speed, and action
management. When multiple objects are animated independently, one
AnimationMixer may be used for each object.
- Time scaling for playback speed
- AnimationAction management
- Memory resource management
- Get actions for animation clips
- Update mixer in render loop
