   雨松大哥：我在动态生成的时候出现 sprite：Sprite（missing） 样的问题 ，是什么原因啊

   请问怎么用AssetDatabase.LoadAssetAtPath读取已经自动分割的素材中单独的一张呢？我得到的素材不是一张一张的而是一张大图，用unity自带的分割工具切好之后要怎么读入？

   雨松大哥。。我不知道2017年了还能不能得到回复。。。我自动生成的clip跟手动拖动素材后生成的clip对照了半天好像没区别。但是代码自动生成的clip既不会动，从别的clip切换过来的时候也不会有反应。比如我向左走的clip是自动生成的，向右走的事手动拖拽的。我按右键会正常播放向右走的动画，按左键的时候物体机会切回默认的sprite图，不会播放向左走的动画， 可能是什么原因导致的呢？

   帧数少的倒是正常 但是为什么我生成了一个50帧的 排列出现了问题 变成0 1 10 11 12 … 这样排下去了 _(:з」∠)_

     不知道怎么弄 只好在99行生成FileInfo[] images之后重新排列 加一行Sorter.Sort(ref images); 只是把文字里面的全部数字提取出来然后按照大小重新排列的 ⁄(⁄ ⁄•⁄ω⁄•⁄ ⁄)⁄ 上Sorter类：
     public class Sorter
     {
     public static void Sort(ref FileInfo[] arr)
     {
     int[] ascending = new int[arr.Length];
     //字符转换
     for(int i = 0; i < arr.Length; i++) {
     char[] charCache = arr[ i].Name.ToCharArray();
     int[] intCache = new int[charCache.Length – 4];
     string strCache = "";
     for(int j = 0; j < charCache.Length – 4; j++) {
     int.TryParse(charCache[ j].ToString(), out intCache[ j]);
     }
     foreach(int item in intCache) {
     strCache += "" + item;
     }

     int.TryParse(strCache, out ascending[ i]);
     }

     //排序
     for(int i = 0; i 0) && (ascending[j – 1] > t)) {
     ascending[ j] = ascending[j – 1];
     arr[ j] = arr[j – 1];
     j–;
     }
     ascending[ j] = t;
     arr[ j] = T;
     }
     }
     }

   你好 我用的是Unity5 前面几处过时的地方修改了 可是还有一个trans.RemoveCondition(0); 提示无法从int 转为 AnimationCondition类型 那么这里的参数应该填什么呢？ 谢谢喽
