Magical Box particles along spline

[Jake]

Hello,

I've experimented a bit with the Curvy Spline, and I've set up particles to move along the length of the spline over the Curvy Spline/Position by Curvy Spline parameter. Is there a way to reverse the flow of particles in the opposite direction on a keypress? I'd want them reversing their flow along the spline, just in reverse.

Also, there seems to be a bug (maybe it isn't) with the particle emitter. If I do something like particlesystem.enabled = true, then switch it to false at some point in order to make the particles disappear, setting it to true again doesn't do anything. Particles don't start working again.

Thank you in advance for the reply.

Sorry for the delay, I'll check this tonight!
