| unloadAllObjects | 确定是否还将卸载从 AssetBundle 加载的对象的当前实例。 |
卸载当前已加载的所有 AssetBundle。
When unloadAllObjects is false, tracking data structures and any memory buffers holding content of the AssetBundle will be freed. But any instances of objects loaded from this bundle will remain intact.
当 unloadAllObjects 为 true 时，也将销毁从当前已加载的捆绑包加载的所有对象。如果场景中有 GameObject 引用这些资源，则对它们的引用将丢失。
不管是哪种情况，除非重新加载当前已加载的捆绑包，否则无法再从它们加载任何其他对象。
See AssetBundles compression for a description of the different compression formats used and their impact on memory while loaded.
