Unity3d NGUI Click to penetrate problem solution

When the 3D scene and the Ngui coexist, clicking on the UI Layer button above will trigger the onmousedown event at the bottom of the 3D object, and sometimes that's what we don't want.

Solution:

If the object in the 3D scene simply needs to be clicked, the EventType property of the UI camera component of the 2d/3d lens can be set to Ui/world, respectively, to separate the click events of the three objects from the UI.

1. Add the UI camera component to the primary camera and set the EventType to world

2. Add the UIButton attribute (ngui-attach-buttonscipt) to add the clicked object to the scene
