Hi,
At first I was using InputEventMouseButton and is_pressed / not is_pressed to detect mouse down and mouse up events, but since I want my game to work on touch screens, I started using InputEventScreenTouch, but then I can detect is_pressed to know if the user is touching the screen, equivalent to mouse down, what do I do in order to detect a "mouse up"? or in other words, is there a way (better to check it constantly on a frame enter event) to know when the user had stopped touching the screen?
