Introducing: DrawMenu! (some free code)

New page

== DrawMenu ==

So a while ago I got really bored and decided to control all of my debugging graphics a little better. The result? A little menu that allows you to select which graphics to show. It's not commented at all and probably a little hard to read but I thought I would at least share it with you guys in case somebody wanted something like this but didn't have the time to create it. Rewrite, reuse, abuse, I don't care, just make sure you enjoy it. :-)

Oh, but if you make any major improvements to it, be sure to let me know.
