Many a pardon if this happens to have been asked or answered already. I have two questions about emitters, the first having to do with them when attached to actors and a second one about them in general:

First.) Is there a way to set it up some that emitters only trigger when a direction, left/right/down are used. Such as an emitter triggering when moving horizontally that would emit high speed low mass particles, or some other combination, to reduce the weight acting on the actor, or applying another force to help movement by applying force behind the actor.

Second.) Is there a way to make sure that an emit always emits in a given direction regardless of the rotation of the object it is attached to. Such as a spinning object that always has a "booster" that fires directly download, regardless of its rotational state.

Cheers!

no and no with the exception of emitters on Craft and Jetpacks.

On jetpacks, is it possible to attach more than one to an actor then?

No. It isn't.

And to clarify on Alenth's initial answer: emitter control is only possible on craft and jetpacks. Removing rotation is not possible at all.
