public void OnStateMachineEnter (Animator animator, int stateMachinePathHash);


animatorThe Animator playing this state machine.
stateMachinePathHashThe full path hash for this state machine.


Called on the first Update frame when making a transition to a state machine. This is not called when making a transition into a state machine sub-state.

The evaluation flow must pass through an Entry node to call this method. Adding this callback prevents the multithreaded state machine evaluation because a script method needs to be called during the state machine evaluation. This method is called while the state machine is being evaluated which is a different execution order compared to most StateMachineBehaviour methods.
