An API function to detect relative motion on landing #1150
Description
A way to detect if an object has landed and is stationary with respect to the thing it has landed on.
I.e. right now my scripts are reliant on the objects speed be less than a certain value, on a moving ship this can't trigger. A way to detect it's landed on a ship, and that all the velocity vectors match the ships e.g. stationary with respect to ship, or train (or below a certain value) would be really useful
