Description 描述

Unloads assets that are not used.

卸载未使用的资源。

An asset is deemed to be unused if it isn't reached after walking the whole game object hierarchy, including script components. Static variables are also examined.

如果对象没有进入到游戏场景，资源被认为没有使用，包括脚本组件，静态变量也被检查。

The script excecution stack, however, is not examined so an asset referenced only from within the script stack will be unloaded and, if necessary, loaded back in the next time one of its properties or methods is used. This requires extra care for assets which have been modified in memory. Make sure to call EditorUtility.SetDirty before an asset garbage collection is triggered.

这个脚本执行堆栈，然而并不检查，所以只从脚本栈中卸载引用的资源。如果需要的话下次再重新加载，这需要注意资源已经在内存中被修改。在资源垃圾回收被触发之前，确保调用EditorUtility.SetDirty。
