Alright I'm using xe to move a missile towards a location. It's got the whole grenade effect, as the spell is called molotov and simulates a molotov cocktail bomb when thrown. However I'm having troubles. Mainly with transfering the fx I created in one trigger and moving it into the timer properly.
Since fx runs on a system, I wasn't sure how to do it properly. Any help on getting the fx's information from the trigger it's created in into the timer?
Mind you these are not my equations. I can't do this level of math. :\ Also I still have a lot of the basic non-missile effect set up, which I'll likely change when I have figured this out. Still optomization suggestions are always +repable
