Unity2018已經把打包過程簡化很多了

我們只需要關心兩個API:

1.BuildPipline.BuildAssetBundles() 打包AssetBundle

2.BuildPipline.BuildPlayer() 打包場景

1.打包AssetBundle

先在資源的Inspector面板最下方 填寫資源所屬的AssetBundle名稱和字尾(字尾可以不填)

再利用BuildPipeline.BuildAssetBundles()進行打包

2.打包Scene

利用BuildPipeline.BuildPlayer()進行打包

為方便使用 先把要打包的場景放入指定的資料夾 通過指令碼批量打包

3.指令碼批量打包

4.打包完畢

5.載入測試

6.打包和測試指令碼
