Unity3d:加载Gif格式图片

unity里不支持Gif格式的图片，网上搜索也没有相关资料，殊不知我们已经太相信度娘了，而没有了自己的分析，我们知道Gif图是由多个静态图做成的，那我们就回归本土，第一步：把gif拆成n个静态图放在集合里

/// <summary>
        /// 拆分GIF（使用.Net框架的Image对象）
        /// </summary>
        /// <returns>The GIF.</returns>
        /// <param name="path">Path.</param>
        public static System.Collections.Generic.List<Texture> SeparateGif(string path)
        {
                System.Collections.Generic.List<Texture> list=new List<Texture>();
                try
                {
                        // 获取图片对象
                        System.Drawing.Image imgGif = System.Drawing.Image.FromFile(path);
                        // 先判断图片是否是动画图片（gif）
                        if (System.Drawing.ImageAnimator.CanAnimate(imgGif))
                        {
                                System.Drawing.Imaging.FrameDimension imgFrmDim = new System.Drawing.Imaging.FrameDimension(imgGif.FrameDimensionsList[]);
                                // 获取帧数
                                int nFdCount = imgGif.GetFrameCount(imgFrmDim);
                                for (int i = ; i < nFdCount; i++)
                                {
                                        // 把每一帧保存为jpg图片
                                        imgGif.SelectActiveFrame(imgFrmDim, i);
                                        Texture2D t2 = new Texture2D(imgGif.Width, imgGif.Height);
                                        t2.LoadImage(ImageToByteArray(imgGif));
                                        list.Add((Texture)t2);
                                }
                        }
        }
        catch (Exception ex)
        {

        }
                return list;
    }

第二步：把集合中的图绘制出来

        private System.Collections.Generic.List<Texture> anim;
        private int nowFram;
        private int mFrameCount;
        private float fps = 1.2f;
        private float time = ;
void OnGUI()
        {
                DrawAnimation(anim, new Rect(float.Parse((Screen.width/-(int)EleWidth/+czdaGo.transform.localPosition.x).ToString()),float.Parse((Screen.height/-(int)EleHeight/-czdaGo.transform.localPosition.y-).ToString()), (int)EleWidth, (int)EleHeight));
        }
        /// <summary>
        /// Draws the animation.
        /// </summary>
        /// <param name="tex">Tex.</param>
        /// <param name="rect">Rect.</param>
        void DrawAnimation(System.Collections.Generic.List<Texture> tex, Rect rect)
        {
                try {
                        GUI.DrawTexture(rect, tex[nowFram], ScaleMode.StretchToFill, true, );
                        time += Time.deltaTime;
                        if (time >= 1.0 / fps)
                        {
                                nowFram++;
                                time = ;
                                if (nowFram >= mFrameCount)
                                {
                                        nowFram = ;
                                }
                        }
                                } catch (System.Exception ex) {
                        Debug.Log("CZDAElementGifInfo_DrawAnimation():"+ex.Message);
                                }
        }
