For example, the solidmask removal is done in
UpdateFace, and might have been needed in Clonk 4 or Clonk Planet, but the
current solidmask code is fine with the call from there.
The precise rule is that only CNAT_Bottom vertices connect to the
landscape and connect at the bottom, too. It doesn't quite fit with
the other procedure-transitions because the movement code doesn't
consider the bottom vertex to touch the landscape in that situation,
but this is probably less weird than the old cornerscale teleportation.
Also don't transition from FLIGHT to Scale when the ComDir points
away from the wall. That tended to stop the Clonk in its tracks on
uneven ground.
Instead of teleporting from sticking with the left/rightmost vertex to the
want to standing on the lowest one at the same position, the Clonk can now
climb using the lowest vertex alone. That means the teleport only needs to
cover only one pixel each in x and y direction to go from sticking to the
side of the landscape pixel to sticking on top of the same pixel.
Also remove some unnecessary x/ydir resets and make comdir in the direction
of the wall the Clonk is scaling keep the up/down direction instead of only
going up.
Scenarios that want to override the default behaviour of BlastObject should
overload the BlastObject function itself. Objects can simply use the Damage
callback and/or set BlastIncinerate to nil.
