[Bullet] Drag force (skid coef)

Started by
0 comments, last by Norman Barrows 8 years, 1 month ago

Hi, all.

There is an object which is controlled with applyCentralForce.
All parameters like setFriction, setRollingFriction, setRestitution, setDamping are defined by default (thus, I changed nothing).
Except for setAngularFactor, I setted up it like vec(0, 0, 0);

My problem is when I want to turn the moving object, I'm facing with skid. It looks like a car skid.
Is it possible to add drag force or minimize skid?
Or is there another way to compensate for centrifugal force?

Please, guys, advice me how I can avoid this trouble. Thanks.
