Is there a way to get a StateMachineBehaviour on a specific State
Something like:
animator.GetCurrentAnimatorStateInfo(0).GetBehaviour<MyStateMachineBehaviour>()
or at least a way to get the State on which a StateMachineBehaviour is. Something like:
foreach (MyStateMachineBehaviour smb in animator.GetBehaviours<MyStateMachineBehaviour>())
print(smb.stateInfo);
If not, why? Is there something I don't understand that makes it bad or useless to need that?
Best Answer
public class AdvancedStateMachineBehaviour : StateMachineBehaviour {
protected AnimatorStateInfo stateInfo;
public AnimatorStateInfo StateInfo
{
get { return stateInfo;}
}
// Use this for initialization
public override void OnStateEnter(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
{
this.stateInfo = stateInfo;
}
}
public static class Utilities
{
public static T GetBehaviour<T>(this Animator animator, AnimatorStateInfo stateInfo) where T : AdvancedStateMachineBehaviour {
return animator.GetBehaviours<T>().ToList().First(behaviour => behaviour.StateInfo.fullPathHash == stateInfo.fullPathHash);
}
}
Thanks for the smart workaround. One has to remember to call base.OnStateEnter if overriding OnStateEnter.
Now the question remains: why Unity doesn't seem to expect us to want that?
This approach only works to get states that aready started at least once before.
You can't do that to, for example, add a callback in your behavior to be called when the animator enters that state.
Well you can always use AnimatorChildState.state.behaviours
