Real GSC, a safe practice sandbox

Everything you type is the same Black Ops 3 GSC you'll write in zm_yourmap.gsc: variables, if/else, loops, arrays, functions, structs, threads and notifies. Your code runs in a small practice interpreter in your browser, so nothing can break and wait 10; takes no time at all.

It only knows a handful of game functions (like iPrintLn, randomInt and spawnStruct) and pretends there's one player, Dempsey. When you're ready for the real thing, the scripting tutorials pick up where this leaves off.
