unity3d如何播放帧动画，我写的这种方法比较麻烦。得一张一张图片的往数组里拖，适合图片较少的帧动画。

效果如下：

![Center][]

上代码吧：

using UnityEngine;
    using System.Collections;
    
    
    public class play : MonoBehaviour {
        public GameObject startscene;//页面
        public GameObject selectscene;
    
        public float animSpeed = 10;//1秒播放10帧图片
        private float animTimeInterval = 0;//每一帧的时间间隔
    
        public SpriteRenderer lantiao;//渲染器
        public Sprite[] lantiaoSpriteArray;//创建精灵数组
        private int lantiaoIndex = 0;//当前播放的帧的索引
        private int lantiaoLength = 0;//数组长度
        private float lantiaoTimer = 0;//计时器
    
        public bool m_bpress; //是否按下
    
    
    	// Use this for initialization
    	void Start () {
            animTimeInterval = 1 / animSpeed;//每一帧的时间间隔
            lantiaoLength = lantiaoSpriteArray.Length;
    	}
        void OnPress(bool isPressed) 
        {
            print("press");
             if (isPressed) 
             {
                 m_bpress = isPressed;
             } 
             else 
             {
                 m_bpress = isPressed; 
             } 
        }
    	
    	// Update is called once per frame
    	void Update () {
            if (m_bpress)
            {
                print("m_bpress:" + m_bpress);
                
                lantiaoTimer += Time.deltaTime;
                if (lantiaoTimer > animTimeInterval)
                {
                    print("in if"); 
                    lantiaoTimer -= animTimeInterval;//计时器减去一个周期的时间
                    lantiaoIndex++;//自动播放下一帧
                    if (lantiaoIndex >= lantiaoLength)
                    {
                        startscene.SetActive(false);
                        selectscene.SetActive(true);
                    }
                    lantiaoIndex %= lantiaoLength;//判断索引是否超过长度
                    lantiao.sprite = lantiaoSpriteArray[lantiaoIndex];
                }
            }
            else
            {
                lantiao.sprite = lantiaoSpriteArray[0];
                lantiaoIndex = 0;
            }
    	}
    }
