Hi, everyone, I just begain to use NGUI, and I am making a sence which has two cameras, one is for the 3D object, the ohter is for the 2D GUI, and I attach a camera control script to the main camera to rotate 3D gameobject, and create a button to press to show/hide a 2d GUI panel, here is the thing I try to solve, when the 2D panel show up, I touch and swipe on the 2D GUI panel, the object can still rotate, but I don't want it to rotate when I touch or swipe the GUI stuff, how could I achieve that, thank you.
