Don't register Mouse Clicks through GUI.
Hello, I have this code. The code is creating a window and pausing the game, the window contains the skills I want to increment. The menu is working great, I only have a problem with it.
When I want to increment the skills the mouse clicks registers through the GUI into the world and I want to prevent that, I only want the clicks to register in the GUI when the GUI is displayed.
Can someone help ? :)

A hack solution is to put a box collider behind your window at the near clip plane of the camera and childed to the camera. The collider is enabled any time your window is enabled.
This question has come up a number of times in the last year, but I don't remember the other solutions.
Thank you for the answer, I'll keep in $$anonymous$$d the hack, but maybe a solution with the GUI will present itself :).
Thanks anyway. :)

Use (Rect).Contains(Event.current.mousePosition) to check if your mouse cursor is inside a GUI box, and set a boolean variable like "mouseOverWindow" to true if it is. Then you check all mouse clicky in your main, non-GUI view against this variable.
Alternatively, if it's just about clicking buttons, you can also use GUIUtility.hotControl.
