Stop being bound by fixed resolution! This kit includes a few scripts that you can implement by themselves, as well as a demo that will start fullscreen (exc. HTML5) and will be the same resolution as your browser window (HTML5) or device/monitor screen. Make anything you like with 1:1 pixel density for clear games and great programs. Includes scripts for resetting window size and view size, as well as one for X coordinates and one for Y coordinates that take a value between 0 (left/top of screen) and 1 (right/bottom of screen).
This is a starter kit so is not fully kitted out, but it's super-easy to modify and make it do other things like making 1:1 games of any size (such as a user-defined resolution chooser). It should save you some time anyway!
