Oh, one other trick is to set body.inertia
to Infinity
so it can't rotate which is good for platforms.

There's actually a new demo I pushed the other day that may help you a bit with this, it's called "Body Manipulation". You can try it out if you clone the matter-js repo and follow the instructions here to build and run the demo.
It's using some new functions currently only available in the edge build. See the code for the Body Manipulation demo.
My initial version used static bodies and translated them every frame, but then they don't have any velocity - so when they strike a player, the player just slides down the edge instead of pinging off it.
I can see what you mean and I think the above demo may also suffer similar issues even though they're not statics. I think ideally you should be using forces here rather than translation (e.g. Body.applyForce
or body.force.x
etc) but I imagine that may be difficult to control.
A better way may be able to fiddle around with Matter.constraints
to do this - e.g. have them pulling in opposite directions on a body, then dynamically change the constraint points.
Thinking about it more, I imagine motors constraints etc. may need to be implemented to do this properly. So I'll put those on the list of things to look at, but I think the constraints approach is probably your best bet as it is now.

The Body Manipulation demo is really helpful. I think I can do a bit of hacking (forcing a Y position after every update) combined with the body.inertia = Infinity trick to get what I'm after!
