Some basics: I'm using Havok Physics with an HKE file exported from Plasma.

I'm trying to move a rigid body by adjusting the linearVelocity and
angularVelocity and adding them to the current linear and angular velocities
respectively, but while my RB rotates as I want it to, it only moves itself
on relation to the world axis.

How do I make it so that when I turn my RB in another direction (say, 45
degrees clockwise), when I go to move it, it moves along that vector?
Thanks in advance.
