3 Hierarchy中新建一个Sprite，然后添加个脚本，脚本中代码如下

using UnityEngine;
using System.Collections;

public class TSpriteAnimator : MonoBehaviour {
	//
	float framePerSecond = 60f;
	SpriteRenderer sr;
	Sprite[] sp;

	void Start () {
		sr = renderer as SpriteRenderer;
		sp = Resources.LoadAll<Sprite>("test");
	}

	void Update () {
		float f = Time.timeSinceLevelLoad;
		int index = (int)(f*framePerSecond);
		index = index % sp.Length;
		sr.sprite = sp[index];
	}
}
