The same applies to other cases like output of thousands warnings/errors
* Arch-Vile resurrection
* Boom point pushers (due to complete lack of z-handling only for line portals.)
* A_RadiusGive
These also require a more thorough collection of portal groups than simple position checks.
It can easily happen that the lower sector has no lines below the checked area, in which case it would not set the dropoffz correctly. To prevent this, P_LineOpening must, when it checks the opening over a sector portal, actually calculate the dropoff to the lower portal itself by calling sector_t::NextLowestPointAt. It also means that FindRefPoint must calculate a proper reference point when one side of the line to be checked is part of a floor portal.
This fixes Clang complaining about unknown command option '-Wno-unused-but-set-variable' when compiling dumb.
Also I got no new warnings on Clang by excluding '-Wno-unused-result'.
This includes:
* allow one sided portal linedefs to be crossable when part of a polyobject. Due to the limitations, two-sided linedefs won't work here. For general use this is still not allowed because making them passable would require some crippling fudging.
* delay portal finalization until after polyobjects have been spawned.
* the camera interpolation also needs to handle angle differences.
The code is still not 100% complete - the most important thing that is still missing is proper handling of P_CheckPosition through arbitrary portals.
- added portal offsetting to all AproxDistance, AngleTo and Vec*To members of AActor.
- optimized displacement retrieval so that the most common case with no offset retrieves a constant null-vector which can be optimized away fully by the compiler.
- early out in P_GetOffsetPosition if there's no portal lines nearby, so that the common case can skip the traverser completely even on maps with line portals.
- made some minor changes to FPathTraverse so that the Add*Intercepts methods can be virtually overridden.
- removed the PortalTracer class because in its existing form it was too costly. Replaced with a P_GetOffsetPosition function that does the minimum required work to get to the translated destination and that's better suited for being called from the Vec*Offset methods. Other use cases will require some changes to FPathTraverse anyway, or some wrapping class like the FMultiBlock iterators.
- renamed sector_t::soundorg in centerspot, changed the type to a fixedvec2 and removed the CenterSpot #define.
Since this thing was used in lots of places that have nothing to do with sound the name made no sense. Having it as a fixed_t array also made it clumsy to use and the CenterSpot #define used a potentially dangerous type cast.
- Split specific parsing for each intrinsic out of ParseExpression0 and
into their own functions.
- Instead of reserving keywords for intrinsics, identify them by name
within TK_Identifier's handling.
* Blocking lines above or below the current sector should only block if they actually intersect with the currently checking actor.
* Sectors above a ceiling portal should not change current floor information and vice versa.
