Summary

Currently, there seems to be no good way to check the mouse is outside the game window.

For example, if the mouse moves out of the game window, I hope to cancel some game UI to improve the user experience.

Possible workarounds or alternatives

I tried using this, but it doesn't seem to be a true trigger and will just keep listening for the event. It will trigger this event repeatedly.

window.addEventListener('mouseout', function(){
  runtime.callFunction("MouseOut")
})

window.addEventListener('mouseover', function(){
  runtime.callFunction("MouseEnter")
})

Proposed solution

"On Mouse Enter Screen" "On Mouse Out Screen"

Why is this idea important?

This may be helpful in many situations.

Another solution is to return -1 to the MouseX/Y expression when the mouse is not in the game screen.
