Took muuuuuch too long but, with the help of some friendly folks on the Godot Discord, I finally have my carrying working.

For those struggling with the same thing I did, to set the position of a RigidBody2D from code, there are 2 ways:

1. In 'normal' code:

python rb2d.set_global_position(newPos) rb2d.move_and_collide(Vector2.ZERO) # update physics

1. In _integrate_forces(state):

python state.transform.origin = newPos

The proof of the pudding is in the carrying it overhead!

HTH!

Finishing early with hopes of an early (and earlier) start tomorrow. GL all!
