Konstrukt Marines Help

Konstrukt Marines Help

Alright got a question. I'm not sure if Talon gets on anymore, so I'll ask you guys.

Well I'm using Talon's Konstrukt Marine models and weapons, and I've got them all attached and what not, but now I got a slight problem. I know how to attach the muzzle flash to the guns, but I'm having a problem figuring out how to make it only appear when the unit attacks. So pretty much the marines are running around with the end of their guns flashing to high heaven when they arent even attacking. I used the Orb of Slow ability as a dummy spell, like he said to do, but it still aint working. Any ideas??

Make a trigger:
Event: unit attacks
Condition: Attacking unit = to [your unit]
Action: Special Effect: Create Special effect attached to the weapon of attacking unit using effect [konstruct weapon flash]

like that
