Hi Magnus,
In v1.2, whenever there is no behaviors/scene graph change
(and no interpolators use), WakeupOnElapsedFrames will
not schedule to trigger since there is no need to render.
In your code, when the object collide, the behavior in
processStimulus() did not change the scene graph,
so Java3D renderer did notrender the scene graph for the
next frame and WakeupOnElapsedFrames will not trigger
again. Therefore, the object appear to stop moving. This
is an expect behavior in v1.2. WakeupOnElapsedTime will
works in your case as it gaurantees processStimulus()
triggered every certain time to change the scene graph.
Thanks.
