Attacking items

Attacking items

if you played battle ship you could understand..
how can you make a item attack..
in battle ship you buy a item (wep) that will attack a random target when you have it in your inventory

anyone knows how he have done it???
(the game is proteckted so you can`t look )

the game is often played on bnet.. if you want to see..

I'm guessing that it's triggered.

He probably checks to see if you have the item within your inventory, and then collects every eligible target and chooses one of those randomly to be smitten by a caster unit.
