Preventing Friendly Fire

[Shade]

Heya people, making a map in which I have triggers that are activated when units are killed. I need to make it so that allies can't kill eachother's units and exploit the triggers I've made.

I've seen it on a few maps where when you manually press 'a' and click on an ally's unit it won't allow you to attack it. Anyone know how it's done?

There are 2 ways...

1. Go through all effects and weapons that deal damage and make them exclude friendly units as a valid target.
2. Use a trigger that detects when a unit tries to attack a friendly unit and then orders the units to stop the attack order. You would still need to do 1 for all the effects.

Actually, if I'm not mistaken you can go to the attack ability and edit it not to taarget allies. But won't let players target allies, but splash damage if it damages allies will still damage them, but most of splash damage SC2 units don't damage your allies.

A unit is attacked by an unit
condition: player(owner of attacking unit) equal to player(owner of attacked unit)
action
unit issue order - order attacking unit to stop.

Sorry for the bad layout, but you get the idea.
