Button over another in the game engine I have a little red plane above a big green plane:

I have set the red plane for one action, and the green plane for another when i click them.

But when i click one the red (in the game) that click activate both of the planes.

How to deactivate the green plane when the mouse is over the red plane?
&nbsp;&nbsp;If the Mouse Sensor is set to Left Mouse Button, it will simply register if the mouse button is pressed, regardless where you do it. 

&nbsp;&nbsp;You can combine it with a Mouse Over Sensor and use an And Controller. Then the Actuator is only triggered when the mouse is over the right object and LMB is pressed.
