Particle and Movie Start



Ok, I'm fairly new to this, and I very well might be missing something, so please bare with me.

One of the things that I would like to do is have a particle system generating particles on a keyboard input. (i.e. I press the "s" key and the particles start being generated.) I can only seem to turn render layer of the particles on or off, but they continue to be generated when not being rendered. Is there anything I can do?

Similarly, I want to have a non-looping movie start playing on a sprite on a keyboard input. Again, I can only seem to turn the rendering on or off, but the movie keeps playing. I've tried to use an interpolation patch and external time control, but the composition continued to become increasingly complex and I never really got anywhere.

I'm ultimately wanting to create a purely quartz composer composition for a presentation for a fundraiser for my high school, so I'm not integrating this into an application.

Thanks for any suggestions you have.

-Scott
