Class Documentation

A physics modifier that sets the particles' rotation. Each particle keeps a rotation as Euler angles in degrees. On each step, before the integration, the client builds the particle's orientation from these angles and replaces the orientation it had. The position is not changed.

The angles come from one of two modes:

Spin (UseKeyedRotation clear): the angles start at InitialRotation and grow by InitialRotationalVelocity * KeyedRotationalVelocity * dt on every step.
Keyed (UseKeyedRotation set): the angles start at InitialRotation and are set to KeyedRotation on every step.
