unity-序列帧动画

  序列帧动画作为一种2D游戏中经常采用的动画技术，使用unity也是很好实现的。只要在场景中新建一个Quad，然后在添加上如下脚本即可：

using UnityEngine;
using System.Collections;

public class AnimateTest : MonoBehaviour {

    private int startIndex = 266;
    private int lastIndex = 331;
    private string path = "dance/dance_";
    private int currentIndex;
    Texture frameAniTex;
    public float framesPerSecond;
    
    // Use this for initialization
    void Start () 
    {
        currentIndex = startIndex;
    }

    void Update()
    {
        AnimaAlways();
    }
    
    // Update is called once per frame
    void AnimaAlways()
    {
        int nowIndex = (int)(Time.time * framesPerSecond) % (lastIndex - startIndex+1);
        if (currentIndex != startIndex + nowIndex)
        {
            currentIndex = startIndex + nowIndex;
            frameAniTex = (Texture)Resources.Load(path + currentIndex.ToString(&#
