This is a 1s1s window box for an OS (Operating System) that anyone can use. All of the buttons work, yet don't require extra sprites, scripts, or even any extra costumes. The nightmare in making this was that I had designed it for use as one window, then decided I could use the engine to make it have two windows at once, or more. To make it able to do this I had to change all of my variables into lists then replace in every spot that had a variable with a list. Let's just say there are a lot of variables. Technically, this script can now handle infinite windows, but the problem is you need to duplicate part of the script for a new window, so I stopped after two. If you don't think this can make two windows or just want to check, download the project, go to the variable WindowNumber near the top of the script and change the 1 to a 2. It won't go any higher than 2. Remember, anyone can use this, or any other engine I've put on this account!
