This tutorial shows how to detect if the mouse is out of the project. This happens because the (x position) block and the (y position) block can only return values that are on the stage.
How to Make the Detector
Create a new sprite called "mouse out of project detector". Make a costume that is a 4x4 square. Create a new variable called "mouse out of screen" for all sprites, and put this in the code:
when gf clicked set [ghost v] effect to [100] forever go to (mouse pointer v) if <not <touching (mouse pointer v)?>> then set [mouse out of screen v] to [1] else set [mouse out of screen v] to [0] end end
Uses for the Detector
Any project that requires the mouse to be in the project such as a maze using the mouse as the player will need to know if the mouse was moved out of bounds in order to cheat. This detector is useful for any project using the mouse to do something other than clicking without other mouse tracking.
