Ok been a long night and cant seem to think of a solution even though I expect there are many, but here is what im trying to accomplish, Id like to have all sprites attracted to one location in the choreo. simplest / best solution? it escapes me...how's bout U?

Thanks, mike

Simplest -

Not sure exactly if it would work, but
Play it backwards.
generate the tga files so that all the sprites are in the center, moving outwards, then reverse the order of the frames.

I was ridiculously pleased with this effort a year ago:

That was done as Chris suggests - I used a force, and rendered out to tgas so that I could then reverse them.

I've had to do this in the past to simulate particles being sucked into a small vent opening.
Its been a while since I thought about the project, but I think I used a force wind to blow the particles
into a cone shaped object. In your case maybe do the same, but make the cone transparent.

are negative forces possible? Can a fan suck things into itself?

Yes. Forces can do a lot in A:M. Just watch this animation.

There are two forces in the animation. One of the forces is attracting sprites, and the other is repelling them (this is done by using positive and negative magnitudes). In between them is a sphere that is casting particles into the scene. It was quite a simple test. I've made many of them, but this was the first one I could find. Hope this helps.

Thanks all,

What I did from the start was build a slight angled funnel with the sprite emitter circling the funnel and let gravity take over. works good enough, Like what Mike Fitz.. its just experiments im working on. I plan on posting what ive done when it looks better....

Thanks for all the ideas, bound to use them all sometime.....
