Ngui making Atlas using Altas maker

Using Ngui version: 2.7.0

(1) about the placement of UI resources:

The placement path for the UI resource is typically stored in the resources folder under the Assets folder, and if the resources folder does not exist, you can create a new one. But why do you have to store it here, for example, to load a firework effect, the custom application to the Unity's resource loading method is: Resource.load (), this needs to put its resources in the folder named Resource.

However, not all resources are placed under the resource folder, when unity generates a game installation package, for folders other than resources, only the resource files used in the scene are packaged, and for the resources folder, because of the dynamic loading of the resource into memory, So it will all be packaged so that it will cause the game's package size to become larger.

It is customary to classify resources in the resource folder, such as the UI, to create a new folder called the UI and place its corresponding resource in the UI folder. Others, the reader's own consideration.
