No, you don't have to download it. It's a buggy third party map editor that has a few extra features over the official editor, but if you ask me, it's not worth the risk. WEU has been known to cause some ugly problems with maps. -VGsatomi
advanced triggers (e.g.: some useful stuff like changing basedamage, range, armor, "sliding" units, a votemenu (crashes game with wrong syntax) and updates of already existing triggers) advanced items (no idea about that) advanced upgrades (same) advanced spells (whatever... never used) mapprotect "custom dynamic light sources" tree units hero glow models multiple choice system "all tiles buildable" unlimited doodad scaling and rotation "advanced melee ai scripts" "hero selection system" "multiboard progress bar triggers"
depending on the map one or many of those "features" can be added to a map. however i wouldnt recommend using it if you dont have to! if you get along with ur normal editor then stick with it. although weu adds certain useful possibilities (i couldnt live without advanced trigger XD) theres still a risk using it as some of those things might cause crashes, compile errors and other problems. always make a backup before editing a map the first time with weu (maybe it does that automaticly, but im not sure about this). u should also remember that you cant open a weumap with the normal editor.
I'm using only standard World Editor, no all those useless "no limits". I think you can implement needed by you advanced triggers in your WE map.
Create map in WEU using Advanced Triggers. Export map script. All those triggers are there [i think ]
The hardest work is to find out interesting you JASS functions from that script and build this what you want to have using them. For advanced JASS coders only [not me ]
