Help Request. Stopping an emitter emitting but...
on Apr 4, 2006 at 2:56:20 pm

Hi all, possibly a dumb question but I have not been able to work this out.

In an animation I am working on I am using a sparkly type emmitter. What I would like to happen at frame 50 is for the emitter ro stop emitting new particles but the particles that have already been emitted aloowed to finish of their activity.

I have only achieved the removal of the entire emiiter at a certain fram so far and so is no use. Might be nissing the obvious but I'd be grateful for some help.

Thanks
Steve

You can animate the Number graph to do this. Set a keyframe at frame 50 with the value of 100 (or whatever it started out at), and then add another keyframe at frame 51 with a value of 0. The particles on screen should continue to go about their business, but nothing new will be born.

Ahh! Yes, that makes sense. I was messing with some of the other functions in a similar vein. But the number would probably be the obvious one I guess.

Thanks Elvis, I will give that a go but I am sure it will work.

What I do when I want the emitter to stop but let the particles that have already been emitted continue is take the Life of the emitter down to zero... works for me.

Interesting approach. Probably ineffiecient though, as particleIllusion will still be creating particles, then killing them right away -- I think. The cleaner solution is to step the 'number' property down to 0 so no more particles are created.

Other methods that appear to work but again are not the best solutions: decrease 'visibility' to 0 (still calculating all of the particles, and drawing them invisible); decrease 'size' to 0 (still calculating and drawing); decrease 'zoom' to 0.

Thanks, Alan... tried what you said and it DOES work better than the way I've done it.
