Conceptually, the landscape stretches infinitely on both left and right hand
borders of the map. So far, the "closed" part of the border only blocked objects
from passing through. (Additionally, there was a bug where you could scale the
border under certain circumstances.) This patch allows objects to properly
move around on the map borders, including scaling the fake terrain.
Not resetting t_attach leads to strange behavior in liquids since detaching from
the landscape usually happens via the Jump action which generally reverts to its
InLiquidAction before t_attach gets reset. By removing the shortcut return after
entering the InLiquidAction, we make sure t_attach gets reset correctly (as well
as immediately executing the correct action instead of doing so after a delay of
one frame).
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.
This avoids some teleporting when there's some material behind the object
and in front of it. Especially useful for small bumps of material in front
of a wall with the new left/right attachment of the foot vertex of the
Clonk.
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.
For example, the proplist in Clonk.ActMap.Walk is saved as DClonk.ActMap.Walk.
Should the script defining the proplist change while the savegame is stored,
the proplist will have the new contents instead of the old ones after savegame
load.
Also, save functions as DFlint.Hit instead of fDFlint.Hit. Loading uses the same
code as static proplist loading.
Curiously, this makes g++ 4.4 use the C4RefCntPointer move constructor,
which was broken until now. Fix it to take a mutable rvalue reference.
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.
