need some help with hero select please

In the hero select part of my map, how do i make it so after somebodys chosen a hero, that hero can't be chosen again? the simplest way if possible please.

Transfer control of that hero to the player that picked it and only allow people to chose heros owned by neutral passive

Or use booleans, set allow[x] to false when unit is picked, where x cooresponds to the unit.

u guys are makin it mroe complicated than u hafto, just disable the trigger that gives the person that hero.

for instance...

Event:
Units enters region Hero 1
Condition:
Unit type = Hero Selector
Action:
Create 1 (Hero 1) at Region 1
Trigger - Turn off this trigger

thats all u gotta do, u can add special effects, or remove the hero selected very easily also

yea u gotta disable it plus you should remove the hero so they would no he is picked

Thanks x0rcist, that made it easy and work perfect. =)

or... you could download a pre-mad hero selection system in the dl section ;)

Yeah, but how would i learn. =)
