I was wondering, before I pull my hair out trying to find a non existent scripting command. Is it possible to make a particle system that works in reverse? In other words, instead of a particle emitter releasing particles into the air, how about making particles from a random point get sucked into the emitter.

Yeah, I know, then it wouldn't be called an emitter.

What ever you call it, is it possible?

I'm not great with particles but I *think* if you use explode as the shape but target the producing object as the follow target the particles will appear all around it but move towards the source not away.

its definitely possible. one easy way is to have the particles target the emitter itself, with the start radius bigger, or start point further away.

It's also sometimes preferable to have the start alpha'd and fading in so you don't see them leaving the emitter.

I used to have an emitter that was a ton of ants all converging on an anthill prim

Thanks, I'll give it a try.

Ah, I should have thought of that. Thanks. I'll have to experiment, and I'll have to get back here and post the results. Thanks for your time.

You could do that with any of the patterns, with the target being llGetKey(). Drop might not be very exciting, though.

use radius to start the particles away from the emitter. and target them at the emitter (or wherever you want them to go), and set a high speed for them to move, with a short life. that should give you the particles getting sucked in look.

You could also try making the particles start transparent, and fade to color, so you can't tell where exactly they are coming from.

If I recall correctly particles can only fade out, not in. If PSYS_PART_START_ALPHA is set lower than PSYS_PART_END_ALPHA it is clamped up to where the two are equal.

I'm starting to dream particles now.. Argh.. No one would feel like making an examlp woud they. First I need the time to do this. I'm not worried this is for a late project.

I'm thinking of makeing a Miroku the Monk Avatar. I have the poofy pants from being InuYasha. I could use the same pants different color. But I want to give him the palm windtunnel effect.

Particles would appear to suck into his palm. But I still have a large boat to finish, I happen to be working on. On my InuYasha AV, I still need to fix his hair, and make a better more improved Sword. That is going to take some experimenting with particles too.

So I have plenty of work to do. Thanks for all the help in the right direction everyone. I really need it.
