Can't control doodads in trigger

I want to turn the 'Fire Blue' doodad on and off in a trigger but can't for the life of me figure out how to do it.
Any help?

You can't reffer to doods on triggers, only destructibles, but there is a work around...On map innitialization, create a special effect on where the doodad shold be, set it into a variable, then you can destroy it with triggers(action-Special effect-create special effect on point, destroy special effect)

You could also create a new destructable using the model of the Blue Fire and do what you need to it.

I'll go with the 'create new destructible' option because I need to set the angle. Many thanks!
