| animator | The Animator evaluating this state machine. |
| animatorStateInfo | Information about the state being evaluated. |
| layerIndex | The current layer being evaluated. |
Invoked during the Animator IK pass. Implement this message to modify the result of the animation after the evaluation of the state machine on a state by state basis.
OnStateIK is invoked every frame for the currently evaluated state, as well the next state and the interrupted state if applicable.
It will be invoked after MonoBehaviour.OnAnimatorIK.
Note: OnStateIK may be invoked multiple times on the same state if that state is synchronized on multiple layers.
