You can ' t place widgets on a layer different than the uipanel that manages them.

Tribute to the original http://blog.csdn.net/chenggong2dm/article/details/39341823

When running a backpack made by Ngui, the newspaper warns:

"You can ' t place widgets on a layer different than the uipanel that manages them."
"If you want to move widgets to a different layer, the parent them to a new panel instead."

Point to open the code to see the source of Ngui, this is written:

[CSharp]View Plaincopy

2. Public void Checklayer ()
4. {
6. if (panel! = null && panel.gameObject.layer! = gameobject.layer)
8. {
10. Debug.logwarning ("You can ' t place widgets on a layer different than the UIPanel that manages them.\n" +
12. "If you want to move widgets to a different layer, the parent them to a new panel instead.", the This );
14. Gameobject.layer = Panel.gameObject.layer;
16. }
18. }

Looked very simple, is to check whether the layer number is the same, if different, report a warning, and force the same layer.

Workaround :

1, if the items in the backpack are prefabricated, then ensure that the prefabricated layers (layer) are consistent with the backpack.

2, you can also use The_gameobj.layer = n in the code; (n is int) to dynamically maintain layer consistency.
