AsssetBunlder打包

unity3d，资源过多的话。可以压缩成一个资源包。加载出来后。可以解压。找到自己需要的资源

就想.net网站。很多图标都是放一个大图片上。而不是一个图标就是一个图片

因为是在项目编辑时候给资源打包。并不是项目运行。所以要用到Editor。untiy编辑类，脚本放到Editor文件夹中

 using UnityEngine;
 using System.Collections;
 using UnityEditor;
 public class AsssetBunlder

     [MenuItem("Custom/SayHello")]
     static void SayHello()

     {
         /*

          */
         Object[] objs = Selection.GetFiltered(typeof(object), SelectionMode.DeepAssets);

         string path = string.Empty;

         foreach (Object ojb in objs)
