BuildAssetBundleOptions.DisableWriteTypeTree

描述

不要在 AssetBundle 中包含类型信息。

指定此标志将使 AssetBundle 容易受到脚本或 Unity 版本更改的影响，但会使文件更小，加载速度略快。此标志仅影响默认情况下包含类型信息的平台的 AssetBundle。Web 平台必须存在类型信息，因此例如，如果您在构建目标为 BuildTarget.WebPlayer 时指定此标志，Unity 将拒绝构建 AssetBundle。

在编辑器中无法加载没有类型树的 AssetBundle。此标志适用于包含在播放器构建中并在每次发布时重新构建的 AssetBundle。

//Create a folder (right click in the Assets folder and go to Create>Folder), and name it “Editor” if it doesn’t already exist
//Place this script in the Editor folder

//This script creates a new Menu named “Build Asset” and new options within the menu named “Normal” and “Disable Write Type Tree”. Click these menu items to build an AssetBundle into a folder.

        //They will be written in the custom folder ("MyAssetBuilds") which needs to exist prior to this call.
        BuildPipeline.BuildAssetBundles("Assets/MyAssetBuilds", BuildAssetBundleOptions.None, BuildTarget.StandaloneOSX);

    //Creates a new item (Disable Write Type Tree) in the new Build Asset Bundles menu

        //Build the AssetBundles in this mode
        BuildPipeline.BuildAssetBundles("Assets/MyAssetBuilds", BuildAssetBundleOptions.DisableWriteTypeTree, BuildTarget.StandaloneOSX);
