Yes, there is typically a one frame delay, specially with the use of physics.
When not using physics, the delay can be removed by forcing the matrix update from script : updateMatrix(player)

This is because the game update happens as follow :

1 : script "onSceneUpdate"
2 : behaviors update
3 : scene update
4 : physics update
5 : matrices update

If you want a perfect attach with no delay, it's better to use parenting (edit > link selection).

There is a base for a 3rd person character in both examples.

If I edit it it still stays cut.
Anyway the issue is a 1 frame delay if you set an object to follow another object with a delay of 0, even if you manually set the position every frame.
I have seen the demo but not the code, although I don't think it applies.

To know when the player can jump in my game I have a ghost box just below the player model and I do isCollisionTest(). I'd check the collision of the player but that's unreliable so I have a ghost object that clips through the ground a bit.
The problem is that I need to either use
