I know nothing about them at all, I just follow instructions on how to make them work when you copied them into another map. But making a spell with vJass, triggers, GUI etc. I dont know how. My head hurts a lot when I try to troubleshoot them when I cant get them to work, probably cuz Im not very smart and cant understand them hahahaha. I guess their worth learning either, you can make some nice spell and systems with it.
