How do I get the mouse movement updated by the actual pixel

AI_Messiah

For some reason I can get the position, but when moving things no longer make sense. I have tried a lot of things I have looked up and nothing has worked. I just want to get where I can move an object (in 2D) with respect to the mouse in exact pixels each pass

This will give you the position on the screen.

get_viewport().get_mouse_position()
