Preset Player Groups such as (All Players) do NOT leak, however (All Players) matching conditions does.
Player Group - Pick every player in ([COLOR="Red"]All players[/COLOR] matching (((Triggering unit) is A structure) Equal to True)) and do (Actions)
Those are completely different things !
The first (All players) is a preset force, which includes what is says, All players...
The second one isn't inside brackets, it looks like this:
Code:Player Group - Pick every player in ([COLOR="Red"]All players[/COLOR] matching (((Triggering unit) is A structure) Equal to True)) and do (Actions)
This will create a completely new force, and will be independant of the (All players) force
Get it ? :S
don't destroy all player variable, if so your all player will be gone forever. All player by default does not leak.
me, Hydra and Komaq explain it lol
