Mecanim Tryout

Let's make Unity's Ethan shake hand with a very very hot invisible chick. Press 'X' to shake hands
Very simple state machine

Idle to Shake Transition

Shake To Idle Transition

Flowchart-
Idle keeps looping
When "Shake" is set >> transition to Shake
Stay there until exit-time has occurred and Shake is set to false (It should be play once)

So we do need to write some code for this, Mecanim can't variables and stuff I think (not sure).

The trick for using "Boolean" trigger in Mecanim is -
Check if we are in proper state.
Set Flag
Next loop - Unset flag

	using UnityEngine;
	using System.Collections;
	public class Shake : MonoBehaviour
	{
	private Animator anim;
	private bool isShaking;
	public int Count;
	// Use this for initialization
	void Start ()
	{
	anim = GetComponent<Animator>();
	}
	// Update is called once per frame
	void Update ()
	{
	if (isShaking)
	{
	anim.SetBool("Shake", false);
	isShaking = false;
	}
	if (anim.GetCurrentAnimatorStateInfo(0).nameHash == Animator.StringToHash("Base Layer.Idle")
	&& Input.GetKeyDown(KeyCode.X))
	{
	Count++;
	isShaking = true;
	anim.SetBool("Shake", true);
	Debug.Log(Count);
	}
	}
	}

Animation re-targeting is cool and all.. but I'm not so impressed with the design / architecture yet. Looks to me like it's gonna end up being a big pile of mess with lot of patch-works everywhere. Hope I'm wrong for my own sake..
