Mouse Inputs Going Through GUI

This will just print false

Keep this connection always connected. I noticed you were using the isPlacingModeOn variable, I’m guessing to check whether they can place. You could try adding to your MouseButton1Down subprogram:

isPlacingModeOn = not isPlacingModeOn
if isPlacingModeOn then
    placeObject()
end

don’t.
