unity2d 动画

1 资源test.jpg(如下)放入Resources文件夹

2 切割图片

点击图片，在inspector中，选择Texture Type为Sprite（2D and UI）,然后点击Sprite Editor，在弹出界面中点击Slice自动切割图片

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];}}
