MecAnim SubState Animation Complete

Attempting this in Unity 4.6 and below will result in a huge mess of unmaintainable code (made that mistake a while back). But with Unity 5's shiny new State Machine Behaviours you can easily monitor a sub-state with a few lines of code. In order to do this we'll need to monitor a bool parameter on our Animator component.

Add a new bool to the animator representing when you are in your sub-state such as "attacking." This worked best for me since I'm monitoring the end of my attack animation sub-state.

On your desired sub-state machine, add this script by selecting it and clicking "Add Behaviour".

 public class SubStateMonitor : StateMachineBehaviour {
    [SerializeField] string myBool;

     override public void OnStateEnter(Animator anim, AnimatorStateInfo stateInfo, int layerIndex) {
         anim.SetBool(myBool, true);
     }
 
     override public void OnStateExit(Animator anim, AnimatorStateInfo stateInfo, int layerIndex) {
         anim.SetBool(myBool, false);
     }
 }

You can now check if the sub-state machine is running anywhere with the following code snippet.

 Animator anim = GetComponent<Animator>();
 bool isSubState = anim.GetBool(myBool);
