RotateVelocity based on y axis or x axis doesn't work. only work if use z axis. package { import com.greensock.TweenMax; import com.greensock.events.TweenEvent; import ...

In Flint, the particles are treated as billboards - they always face the camera. This is a simplification for performance purposes. I'm debating whether to change this in a future version. The upshot ...

e.g.
renderer.camera.position = new Point3D( 0, 200, -300 );
renderer.camera.target = new Point3D( 0, 0, 0 );

Meanwhile, if you need full 3D perspective, you should use the Away3D renderer and use full 3D objects. (N.B. If you use Away3D sprites you again won't see the rotation.)]]>
