ObservableStateMachineTrigger

'ObservableStateMachineTrigger' provides convenient way to handle various 'Animator' event.

Setup ObservableStateMachineTrigger

1. Select 'Base Layer' in a animator controller
2. Add UniRx's 'ObservableStateMachineTrigger' component

Now, you can fully retrieve and handle any change of animator's state via 'ObservableStateMachineTrigger' observable.

ObservableStateMachineTrigger[] triggers;

void Start ()
{
    Animator animator = GetComponent<Animator>();
    if (animator != null)
    {
        triggers = animator.GetBehaviours<ObservableStateMachineTrigger>();

        foreach (ObservableStateMachineTrigger trigger in triggers)
        {
            trigger.OnStateEnterAsObservable()
                .Subscribe(x =>
                {
                    Debug.LogFormat("state name:{0} nameHash:{1} layerIndex:{2}", x.Animator.name, x.StateInfo.shortNameHash, x.LayerIndex);
                })
                .AddTo(this.gameObject);
        }
    }
}

Note that UniChan has two layers, 'Base Layer' and 'Face'. The above code put log whenever UniChan's animation is changes.
