Hi, I apreciate all the help I get here on the board

So, here are two more questions..
1. An AI(md).ini question:
How does the AITriggerTypes work? Is this needed for the TeamTypes? Or do the AI make the TeamTypes without a Trigger? And when is priority= used, is it used when AI makes the TeamTypes without triggers?
2. DeathWeapon?
I want to make the ChaosDrone release gas upon death, is this possible? When it is destoryed I want it to fire its gas once more.. I added DeathWeapon=ChaosAttack to the Chaos Drone, but it doesn't release a gas?
thnx!
