I use ngui to create some Ui button, so I want when i move the positon to an object, the object will show the button,
but ngui is put its object in its own ui camera, so I could not just set the button's screen positon,
I have to know the windows height and width, and use the (0,1)screen space to multipy,
so the final question how I can get the windows height and width? I can get sceen , but how to get the windows???
