JASS Information. Should I be using it?

I find quite a lot of people use JASS. I'm kinda noob at mapping in a way that i'm workinf on my first project. I can manage some pretty advanced stuff but should I learn JASS? Is it hard to learn? What kind of things can I do with JASS that I wouldn't be able to do with triggers? As far as I can tell, its a type form of triggering where you just type in the commands.

Yes.

Oh yeah. You can make (more*∞) dynamic triggers. "The Tutorial": http://wc3campaigns.net/showthread.php?t=74894

It is not hard to learn at all, at least it was not hard for me. If you have been able to learn how to use the GUI, then you should be able to learn how to use JASS too.

First of all, you can make your code multi instanceable, leak free and a lot more efficient with JASS. Second, there are several functions that you don't have access to in the GUI that you have in JASS, for example trackables, lightning effects with z heights, gamecache + return bug based systems and a lot more.

So yes, you should be using it.

You can use JASS exactly the same way you use GUI. That's the way I learned how to use it, I started converting all the triggers in my map from GUI to JASS.

I've said this before, but you can kind of think of JASS as a life skill(I don't know JASS myself, but I don't fully understand GUI).
