Cool! I was playing around with my lil asteroid sim[1] and I wanted to trace the trajectories of the asteroids, so I put a particle generator in the asteroid "base class" and set it to emit sixty particles with lifetime set sixty seconds, zero momentum and velocity, and unaffected by gravity. I bet you could adapt that to make a "scent trail", eh? [1] https://git.sr.ht/~sforman/SpaceGame https://git.sr.ht/~sforman/SpaceGame but it seems I deleted the experiment. The commit that has it is https://git.sr.ht/~sforman/SpaceGame/commit/7cc3981631db22be3fa77dc479f111ff86f91a08 https://git.sr.ht/~sforman/SpaceGame/commit/7cc3981631db22be... FWIW.
