Thanks jcl, I understand fully now.

This -is actual part of my lack of understanding. I had submitted a "blame the manual" post about not only correcting the chart but possibly about a rewrite of this section. It is one that has caused me the most trouble, from confusion.

Thank you for your time

It does in fact do just that. If the collision hull is a shape around the player, the bounding box sets how far into that shape a penetration can happen. We c_updatehull is called, it creates the hull at largest needed size (at a frame), and set the bounding box at that size as well. So it's updating the bounding box to the max limits of the hull. Then using vec_for_min/max you can shrink the bounding box, allowing more penetration into the hull shape before a collision stop is triggered. Hull's would be something we do not see or really deal with at all. They are engine level items. The need for c_updatehull as a command, it would seem, exist only for the reason stated in the manual - So we can force a recalculation after make a deformation or other shape change to the model.

I hope I am both right and you understand now. c_updatehull sets the box to the max size of the hull every time. Not the real size of the player.
