Hey guys, I got behind on my email, so sorry for not attending to this
sooner. I messed with this code a lot in the past, so I knew where to
go with this one. So emissionRate and EmissionRateFade are both floats
now. I added a simple float emissionRateRemainder data member to
ParticleSystem (hmm, I probably should have marked it mutable) and this
just keeps track of the floating portion that isn't used at each frame.
