So, something like this for Victory/Defeat?
Code:
Untitled Trigger 001
Events
Unit - A unit Dies
Conditions
(Owner of (Dying unit)) Equal to Player 12 (Brown)
Actions
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
(Unit-type of (Dying unit)) Equal to Paladin
Then - Actions
Player Group - Pick every player in (All allies of (Owner of (Killing unit))) and do (Game - Victory (Picked player) (Show dialogs, Show scores))
Player Group - Pick every player in (All enemies of (Owner of (Killing unit))) and do (Game - Defeat (Picked player) with the message: Defeat!)
Else - Actions
Im not sure if you have the enemy as Neutral Hostile, or owned by a player. Change the first condition to whichever it is. And change
Code:
(Unit-type of (Dying unit)) Equal to Paladin
to whatever type of unit the boss is.
Also if you want, just use the above format
Code:
(All enemies of (Owner of (Killing unit)))
And make a wait, or give them a message, or whatever you want extra.
The arena is a pretty big trigger, so it would probably be best finding a old unprotected arena and learn how to do it from that. If you PM the map to me, i could try to work on it..
