Here's what I've got... At compile-time, a TG [moverNode] that has no children. Associated with it is a PositionPathInterpolator(new Alpha(-1, 3000), moverNode, axisOfTranslation, knots, positions). Then during execution, I add children to moverNode and set the positions, axisOfTranslation, and bounds of the interpolator to the desired values. I'm wondering how I should go about actually making this thing animate. Is it even possible with this setup? If not, how do you suggest I fix it? I need it to move 2 objects simultaneously, but not always the same 2 objects. All of the objects have separate BG parents (so I can move them around on the SceneGraph) which in turn have a single TG for a parent. The moverNode is also a child of the top TG. I thought this arrangement would make it a bit easier to animate, but I can't add Interpolators after compile-time, so I'll have to reuse the one. I think. I'm a little fuzzy on whether or not I can reuse it. Perhaps someone could shed some light on the subject for me? Thanks in advance.
