【Resources】
The Resources class allows you to find and access Objects including assets.
Resouces类允许你寻找和访问Objects与Assets。
In the editor, Resources.FindObjectsOfTypeAll can be used to locate assets and scene objects.
在编辑里，Resources.FindObjecsOfTypeAll可以被用于定位assets与场景对象。
All assets that are in a folder named "Resources" anywhere in the Assets folder can be accessed via the Resources.Load functions. Multiple "Resources" folders may exist and when loading objects each will be examined.
所有的assets只要在一个在Assets目录或子/子子/...目录下且名字为"Resouces"的目录中，就可以通过Resouces.Load来访问。也就是多个Resouces目录可以并存，当加载对象时每一个Resouces目录都会被检查。
