Thanks!

Right, I must have misread the documentation for speed. I assumed that was a 2d vector as well. Having "movement" exposed as read/write to script would indeed solve this for me

A small bump on this in case it was missed during summer

It would be useful to be able to read and modify the speed of asteroids at runtime. This could be used i.e. for making tractor beam turrets or deflector shields.

An alternative to having it be writable would be something similar to PushBackTriggerEffectItem that modifies speed instead of position ...
