abcc6049b9 - made the z coordinate part of the CheckResults for the MultiBlock iterators and use these for all height checks in the iterator loops. This will later make it easier to support arbitrary portals with height displacements. 2016-02-22 12:05:36 +01:00

02d7572343 - some header dependency cleanup so that it is no longer needed to include portal.h to get the inline functions. Portal.h has been reduced of most dependencies now so that including it is cheap and can be done in other headers.
- some consolidation in p_map.cpp. PIT_CheckLine and PIT_FindFloorCeiling had quite a bit of redundancy which has been merged.
- Ĩontinued work on FMultiBlockLinesIterator. It's still not completely finished.

1b88052bba - started refactoring ZatPoint calls which need to be portal aware.
To summarize, anything that just works with map geometry doesn't need to bother, as does the renderer. (i.e. nearly all r_* files, p_floor.cpp, p_ceiling.cpp et.al)
But all calls that are somehow related to actor positions need to be made aware of potential portal transitions:

 * added FloorAtPoint, CeilingAtPoint and PlaneAtPoint methods to sector_t, which can be used to calculate a plane's height with relation to a given actor, even if that actor is on the other side of a portal.
 * added HighestCeilingAt and LowestFloorAt methods which traverse all ceiling/floor portals until they find an impassable plane.

6adb069506 - rewrote p_local.h so that it doesn't pull in the entire bunch of headers.
This was to resolve some circular dependencies with the portal code.
The most notable changees:

 * FTextureID was moved from textures.h to doomtype.h because it is frequently needed in files that don't want to do anything with actual textures.
 * split off the parts from p_maputl into a separate header.
 * consolidated all blockmap related data into p_blockmap.h
 * split off the polyobject parts into po_man.h

344dda4a1a - Replaced toint/quickertoint with the portable routines from xs_Float.h. The
former used fistp, which is not portable across platforms, so cannot be
  used in the play simulation. They were only suitable for the renderer.
  xs_Float.h also has a very fast float->fixed conversion, so FLOAT2FIXED
  uses that now.
  (And I also learned that the FPU's round to nearest is not the rounding I
  learned in grade school but actually Banker's Rounding. I had no idea.)
  (Also, also, the only thing that could have made quickertoint faster than
  toint was that it stored a 32-bit int. I never timed them, and I doubt in
  practice there was any real difference between the two.)
- Changed atan2f to atan2. Using floats is not a win, because the result is
  returned as a double on the x87 stack, which the caller then needs to cast
  down to a float using fst/fld.

3f003e06db - Replaced the use of autoconf's WORDS_BIGENDIAN with __BIG_ENDIAN__, since
latter comes predefined by GCC.

00b21e4b96 - Apparently, YASM is not a suitable substitute for NASM when doing Win32 builds.
- Removed extraneous printf parameter for Texman.Init startup message.
- Added newlines to the ends of a few headers that were missing them.
- Fixed more GCC errors/warnings.
