Make checkbox not visible, but still functional.

Hello!

Currently, I am trying to make a checkbox control my fullscreen/windowed mode function in my game. I am trying to get the checkbox to go underneath the sprites I am using for the artwork of the checkbox, however when I send the box to the bottom layer, it's still visible on the top layer. Basically, I want the checkbox to be not visible on screen, but still able to be used. Is there any way of doing this easily? Or at all? Massive thanks to anyone who is able to help.

Awesome, thank you! However, I'm still trying to figure out how to allow the frame to change back and forth between true and false by clicking on it, if that makes sense. Like when I click the sprite, it changes frames, but when I click again nothing happens. And then how would I apply this to making the game go to fullscreen and windowed mode? Thanks again!

Create a sprite MyCheckBox, add an instance boolean variable FullScreen. Add two frames to this sprite, set animation speed to 0.

Then do this:

Mouse on clicked MyCheckBox 
 -> MyCheckBox toggle boolean variable FullScreen
 -> MyCheckBox set animation frame to self.FullScreen

That's awesome. Thanks a bunch! I really appreciate your help!
