BoxColliders does not support negative scale or size.

UNITY NGUI报错信息如下：

BoxColliders does not support negative scale or size.
The effective box size has been forced positive and is likely to give unexpected collision geometry.
If you absolutely need to use negative scaling you can use the convex MeshCollider. Scene hierarchy path "UI Root/PopUIRoot/charge/Offset/TabContent/Charge-TianBaoLuoPan(Clone)/offset/luopan/Offset/Buttons/TenResult03(ren)"

原因是：BoxColliders 的size是负坐标，如下图，解决办法：改成正数即可
