Unity C# 打包AssetBundle与场景

Unity2018已经把打包过程简化很多了

我们只需要关心两个API:

1.BuildPipline.BuildAssetBundles() 打包AssetBundle

2.BuildPipline.BuildPlayer() 打包场景

1.打包AssetBundle

先在资源的Inspector面板最下方 填写资源所属的AssetBundle名称和后缀(后缀可以不填)

再利用BuildPipeline.BuildAssetBundles()进行打包

2.打包Scene

利用BuildPipeline.BuildPlayer()进行打包

为方便使用 先把要打包的场景放入指定的文件夹 通过脚本批量打包

3.脚本批量打包

4.打包完毕

5.加载测试

6.打包和测试脚本
