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AssetBundle2.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

(1)可以利用BuildPipline.BuildAssetBundles()进行打包。注意：场景包内只能给.unity场景文件填写资源包名，不能给其他资源命名，否则打包会失败一个场景ab包内可以包含多个场景文件，场景需要的资源会自动关联有些资源是Editor下专用的。不会被打包进ab里 比如LightingData.asset使用方式是www加载场景ab包后 先调用www.assetBundle 再调用SceneManager.LoadScene("name")

(2)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
