The GMSystemOverlay, is a very light overlay menu that contains valuable information to your game. It contains information like:project name, build number, device id, FPS, mouse position, volume control, resolution, dpi, operating system, date/time, and user-defined variables. Your testers don't have access to your code or a debugger, so help them out a bit by showing system information that is valuable when figuring out device specific issues. Just tweak it a bit, and drop it into any room you want to track information on.
V1.0.1 Mar 8 2016 Changes: -Bug Fixed: Scalable windows break the toggle button position -Bug Fixed: Scalable windows make font sizes appear too small or too large. -Bug Fixed: Creating the obj_sys_overlay after the game_start event (IE: Using an object-placement-controller to create a new instance or starting a new room) throws errors.
Version 1.0.1 Plays nicely with Mobile Devices too. Where Version 1.0.0 was very touchy.
