5.x的assetbundle與4.x以及之前的版本有些不同，不過本質是一樣的躏尉，只不過5.x打包assetbundle更為簡單和人性化了蚯根，總體來說只需要三個步驟：
//這里是一個資源包數(shù)組，其中每一個資源包又可以包含多個小資源胀糜，所以一般情況下一個資源包就足夠了
AssetBundleBuild[] _ABbuild = new AssetBundleBuild[1];
第二步：給資源命名以及指定需要打包的資源
//資源包的名稱
_ABbuild[0].assetBundleName = "打包assetbundle出來之后的文件名";
//資源包下的資源名稱颅拦，一個資源包可以包含多個資源，資源由從Assets開始的路徑組成且包含自身后綴名
string[] _allassetname = new string[3];
_allassetname[0] = "Assets/1.png";
_allassetname[1] = "Assets/2.prefab";
_allassetname[2] = "Assets/3.FBX";
_ABbuild[0].assetNames = _allassetname;
第三步：開始打包
//打包到路徑E:/test/mytest
BuildPipeline.BuildAssetBundles("E:/test/mytest", _ABbuild);
