Trigger Help

[Mark.iv.angel]

I need Help With a trigger: So i am making an arena which has a few confusing triggers, I have everything except a failsafe too ensure that the random hero(that is picked to go into the arena) isn't picked twice. So basically this is what i got for the random pick:

• if (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • if - Conditions
    • (Owner of (Dying unit)) Equal to player 12 (Brown)
    • Randomhero Equal to 12
  • Then - Actions
    • Unit - Move (Dying unit) instantly to (Random point in Arena <gen>)
  • Else - Actions
    • Do nothing

I made it so it kills the heroes and they basically re spawn in the arena.
What would i do to make it so it wouldn't pick the same (Dying hero) twice

Are you meaning other people pick that same unit or your unit? You could also just turn off the trigger after the unit is picked.

Create a pool of heroes (group, array, go nuts as long as it holds units). Every time you pick a random hero from it you simply remove a hero from it. Thus the next time a hero is picked it can not be the same hero as picked last time due to them being remove from it. Just remember to add the heroes back to the pool when appropiate.

I advise the use of an array, as getting random elements is far more efficent than if you were to use a group.
