What do you mean exactly by forcing a fixed time step?

He means, use pSpace.update(1/60f, 0);

I’m telling you… you should really try to build SiO2’s bullet form source and just pass a fixed timestep to bullet. For native bullet this will clear up 1000 weird things. Like, change this line: pSpace.update(t); to: pSpace.update(1/60f); …and see if your weird problems magically go away.

OH! did not know it can take a second argument called maxSubSteps. Searched the web for it … and … old doc says : maxSubSteps: Should generally stay at one so Bullet interpolates current values on its own. A value of zero implies a variable tick rate, meaning Bullet advances the simulation exactly timeStep seconds instead of interpolating. new doc says: It is perfectly fine to stepSimulation(1/120 , 0) to get a fixed timestep of 120 Hertz for example. It mentions you can safely use …
