BtRigidBody and applyForce

[ryp]

Hello guys,

I'm porting the physics of an existing vehicle to bullet. My problem is the way I'm supposed to feed these forces to benefit from bullet's integrator.

What I have now is a callback that i registered with bullet to be called before each internal tick.
At this point I set all the forces with applyForce for my vehicle, and let bullet compute. This WORKS.

Is this the way I'm supposed to feed forces ?
The thing is, I don't know if bullet is using an interpolation on the forces I feed, or if it just accept these forces as constant over the tick interval.

From what I know it takes them as constant over the timestep and applies them. If you get accurate results, you can still check the force feedback to see if your values come out again.
