I know, I know, search. But I have! I've searched almost every ARMA2 site I can find. Lots of tutorials on things, but I can't pin down this exact thing:
How do I spawn things mid-game?
For instance, I've got a plane that gets shot down during a mission. When this happens, I want to place some smoke plumes. I've got the smoke plumes coded, but obviously I don't want them there until the plane goes down. What needs to go in the trigger's onAct field to spawn my object?
