All Random And Unique Heroes (Help Needed !)

Hello again..

I made -ar mode in my game that gives random heroes to all players.To do this, i used the method below.(I am using GUI Triggers.)

I have created an unit array named RANDOM_HERO_ARRAY, and filled it with heroes in map init. event.

Example:
RANDOM_HERO_ARRAY[0]=Paladin
RANDOM_HERO_ARRAY[1]=Archmage
...


And when the host writes -ar as a chat message.


Player Group - Pick every player in (All players) and do (Actions)
Loop - Actions
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
((Picked player) slot status) Equal to Is playing
Then - Actions
Player - Set (Picked player) Current gold to 0
Unit - Create 1 RANDOM_HERO_ARRAY[(Random integer number between 0 and HERO_COUNT)] for (Picked player) at ((Picked player) start location) facing Default building facing degrees
Selection - Select (Last created unit) for (Picked player)
Camera - Pan camera for (Picked player) to ((Picked player) start location) over 0.00 seconds
Wait 1.00 seconds
Else - Actions

( HERO_COUNT is Array's Ubound, there is no problems about this.. )


And I have two problems with this script:

1) It causes terrible lag.In Dota -ar doesnt cause brutal lag like this..Even if I set wait to 3 seconds, it causes terrible lag..

2) This is the real issue..When I use this script, there is no limit of same heroes randomed.I want a hero to be selectable only one time.So all players get unique heroes.


What can I do? Need help of some experienced devs :\

try preplacing every hero in the map for neutral player, and remove those heros on map start ...

could help, dunno

didn't really understand :S

Do a trigger that runs at map init which Create and destroy each hero in your map for a neutral player. This will solve something called first time lag.

Doesn't it tell you to not use waits within pick players block?

On the note of your hero multiplicity, run a check inside of it to make sure there is not a hero of the chosen type on the map already, and if so, have it random another.
