Need Help With Character Selection

Call me stupid, but I cannot understand the triggers to select characters. Im thinking of making a map with as little SFX as possible cus I have not much time to actually study triggering, but i need to learn hwo to make a char select thingy. Anyone can help and post a simple tutorial or even a lil step by step 4 me?

If you mean like the wisp selection, simply make it so if a player enters the region with a wisp, kill the wisp, create the unit at the starting point, and you're done. It'll look something like this:

Event:

A Unit Enters (RegionA <gen>)

Conditions:

Actions:

Kill (triggering unit)
Create unit (DemonHunter) at (RegionB <gen>) for owner of triggering unit.

Thats the simplest trigger I can think of for char selection.

Ok, but can u tell me how to make selected characters unselectable by other players so everyone has a different class?

just add Trigger - turn off (this trigger) in your action.
