RigidBodyController::SetSpinFrictionMultiplier

Defined in: C4Physics.h

Sets the spin friction multiplier for a rigid body.

Prototype

void SetSpinFrictionMultiplier(float spin);

Parameters

spin The new spin friction multiplier.

Description

The SetSpinFrictionMultiplier function sets the spin friction multiplier for a rigid body to the value specified by the spin parameter. This value multiplies the ordinary friction coefficient and, if nonzero, applies a frictional force to a rigid body that is generally spinning on a single contact. Since such a contact point would have very little tangential velocity, ordinary friction would do little to slow the motion, so the spin friction must be applied to oppose the angular velocity. Typical values for the spin parameter are in the range [0.0, 0.5].

The initial value of the spin friction multiplier is 0.0.
