Ok I can manage to attach a normal emitter to a standard keyframed mover that only moves by changing it's location, but I'm having major trouble with attaching an emitter to a mover that moves by changing it's rotation around it's pivot point. Here's the scenario:
I've got a LoopMover - rotating around it's pivot point (the pivot point of which I changed using the PrePivot values) with two keyframes - 1 at the start of rotation, 1 at the end of it. I've set up my emitter as normal, placed it in relation to the mover where I want it to be and used the AttachTags correctly as far as I'm aware. Depending on my test runs, here's the results I get:
1) The emitter shows up, but doesn't move with the mover at all. Just stays put.
2) The emitter moves, but not in relation to the mover itself. Ie, if I place the emitter at the corner of the mover and the mover rotates, the emitter tends to simply zigzag back and forth along one axis while slowly creeping side to side along another axis.
3) The emitter (as in the case of using an xEmitter instead of normal Emitter class) simply doesn't show up.
In none of these cases does the emitter actually stay in the spot of the mover that I placed it when the mover actually moves. So I guess my question is - am I doing this completely and utterly wrong or am I running into engine quirks at this point? In either case, how might I go about solving it?
