On quaternion rotation problem

[icyboxs]

Thank you for your reply.

I think this is what you’re looking for.

Quaternion rotation = spatial.getLocalRotation();
Vector3f direction = camera.getLocation().subtractLocal(spatial.getWorldTranslation());
direction.setY(0f).normalizeLocal();
Quaternion target = new Quaternion().lookAt(direction, Vector3f.UNIT_Y);
rotation.nlerp(target, .1f);
spatial.setLocalRotation(rotation);

This reply made me understand what I should do.

Quaternion to Vector3f conversion

Is there a way to convert a Quaternion to a Vector3f? I found these two methods on a couple Unity forum posts, but they aren’t working for me. // always points in the Z+ direction, no matter the rotation. Vector3f rot = spatial.getWorldRotation().mult(Vector3f.UNIT_Z); // doesn't seem to effect anything... float[] angles = new float[3]; spatial.getWorldRotation().toAngles(angles); Vector3f rot = new Vector3f(angles[0], angles[1], angles[2]).mult(Vector3f.UNIT_Z);

Can you tell me how you finally converted quaternions into vectors?
