I agree, though you missed my point. I am telling you that without hack-arounds, you can get results similar to the kinematic bodies. You have to create some extra events (not in the tenths of thousands) and the precision is a bit off, but it can be done. Sure, utilizing everything box2d can offer (I think it can do springs, particles, liquids...) will be super, in the meantime we have to be more creative
Here, my example with the pin code disabled. It kinda works. It's a start and it uses just 4 events for the platform movement. Other, more advanced users than my self, surely can make it move even with easing in/out, like the Sine behavior does.
