| animator | The Animator evaluating this state machine. |
| animatorStateInfo | Information about the exited state. |
| layerIndex | The current layer being evaluated. |
Invoked on the last update frame when a state machine evaluates this state. Implement this message to react to a state ending.
OnStateExit is invoked when a transition to a state has completed or has been interrupted. It will be invoked before OnStateUpdate of the next state.
Note: OnStateExit may be invoked multiple times on the same state if that state is synchronized on multiple layers.
