AssetBundleBrowser和assetbundle在游戏中的使用

1导入assetBundleBrowser（商店可下）

2通过Window —> assetBundleBrowser

拖入资源，创建assetbundle

 

image01，image02分别使用了同一张图片资源，将这两张图做成预制体，然后做成ab包

image01   和02   同时使用一张相同的图片，打出来的两个ab包分别是24k

将image01,02两个使用的通篇单独打一个包，这个时候，01，02预制体ab包分别是3k,图片资源的ab包是23k

而这个时候，01和02代表的ab包有了依赖，都有对于图片资源的依赖

当存在AssetBundle有互相依赖的情况下，要首先加载依赖的AB包资源，然后在加载自己的资源，否则会导致自己的资源不完整
