What the speed moves depends on the behavior. A Fire particle covers this many leptons along its line of fire each frame, anything from about a quarter slower to a twelfth faster, and a flame given no speed at all is flagged for death on its first logic frame before it has traveled anywhere. A Smoke particle climbs by this many leptons a frame, with a random one lepton added or taken away as it is created so a plume does not rise as a solid column. A Railgun particle steps this far along the beam each frame, after the holding system has added its own perturbation to each particle it lays down. Gas, WeakGas, Spark and Web particles hold a speed but never move by it — a spark’s motion comes from XVelocity, YVelocity and ZVelocityRange instead, and a web particle does not move at all.
A cell is 256 leptons across, so the stock flame’s 28.0 crosses a cell in nine frames while a railgun particle’s 0.4 barely creeps. Deacc takes the speed back down from here, and a successor created through NextParticle inherits the speed its predecessor had reached rather than starting again at this figure.
