790e13e5cb fixed: For sight checks the 'eye' of the seeing thing should be placed at 3/4 height, not half its height. 2016-04-07 12:14:34 +02:00
Christoph Oelckers
3923039a1b - fixed: a sight check that starts right on a linedef should ignore that linedef.
Trying to calculate a slope to the target from this linedef's opening will always result in failure because it'd involve a division by zero.

8cbdbdaf70 - fixed: The PathTraverse and sight checking code may not assume that ceiling(x) == floor(x)+1.
This will fail when a trace starts directly on a block boundary in which case x is a whole number. It should always use 'floor(x)+1' to ensure that the calculated point is at the right or upper edge of a block.

3f5e0c682e - fixed: Due to the iteration limit of 100 in the path traverse code, running a trace was effectively limited to somewhere around 12800 map units. Also added the safer exit condition checks from the sight checking code to FPathTraverse. 2016-04-03 21:41:58 +02:00
Christoph Oelckers
931774ab38 - fixed some issues with the PathTraverse and sight checking code:
* typo in calculating end position from a trace vector
 * must use floor to convert from floating point block coordinate to block index to account for running off the negative side of the blockmap. (Int cast always rounds toward zero which is wrong here.)
 * bad calculation of sight checking slopes - they has the actor's z coordinate duplicated.

- fixed scaling of automap markers.

8fd76f0c8a - floatified bmaporgx and bmaporgy, allowing to remove the gross overflow prevention hacks present in the blockmap code. 2016-03-31 09:23:14 +02:00
Christoph Oelckers
77f2530236 - floatified the sector plane movers and removed some of the ZatPoint conversion cruft. 2016-03-30 09:41:46 +02:00
Christoph Oelckers
c7ae4688a3 - replaced all direct access to vertex coordinates with wrapper functions.
So that code replacement can be done piece by piece and not all at once.

fd46909b1a - made partial floarting point aliases for EV_DoCeiling so that all the calls in p_lnspec.cpp match the master branch for merging. 2016-03-28 17:41:13 +02:00
Christoph Oelckers

8b6b5e7b1c - preparation for upcoming work: rename the fixed point versions of PosRelative. 2016-03-25 14:18:50 +01:00
Christoph Oelckers
4155e84a1c - made player_t::crouchoffset and FPlayerStart's coordinates doubles and added a float version of divline_t so that I could complete the conversion of Hexen's game code.
- consolidated the actor based damage factor code which was repeated multiple times in various damage inflicting functions.

4e60ea0252 - made AActor::alpha a floating point value
- replaced some uses of FRACUNIT with OPAQUE when it was about translucency.
- simplified some overly complicated translucency multiplications in the SBARINFO code.
2016-03-21 12:18:46 +01:00
Christoph Oelckers
cff8e51811 - converted AActor::height to double. 2016-03-20 20:55:06 +01:00
Christoph Oelckers
51b05d331d - replaced AActor::vel and player_t::Vel with a floating point version.
- Converted P_MovePlayer and all associated variables to floating point because this wasn't working well with a mixture between float and fixed.

Like the angle commit this has just been patched up to compile, the bulk of work is yet to be done.

f852ead99a - fixed: The initial check for ceiling and floor portals must be done when the trace's start position and its sector has been calculated. SightCheck::init is too early for that. 2016-03-08 10:44:03 +01:00
Christoph Oelckers
2cd74118f6 - fixed sight checking through portals.
Notes:
 * It is actually not enough to disable the early-out condition for the current block if there's a portal. It must be disabled for the entire rest of the trace because otherwise the collected lines never get processed.
 * The block bounds check cannot be done globally with portals in the game. The actual trace can easily end up outside the blockmap bounds if portal offsets are factored into the distance between the two actors.

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

13e25faea7 - p_sight.cpp, p_spec.cpp and p_switch.cpp refactored. 2016-01-20 14:20:14 +01:00

867b7767ef - ignore COMPAT_POINTONSIDE in a few places where the side effects of the old P_PointOn*Side functions are either not needed or problematic:
* the sight checking code needs to be as precise as possible and should not depend on some old semi-broken routines. (This is more a precision issue of these routines - P_PointOnDivlineSide removes the lower 8 bits of each value - than having an issue with returning the wrong side in some cases.)
 * for slope creations it is flat out wrong to use the old routines at all.
 * also ignore this in the modern (box-shaped) case of FPathTraverse::AddLineIntercepts. This functionality is new to ZDoom and therefore not subject to compatibility concerns.
 * the line-to-line teleporter. It seems the hideous fudging code was just there to work around the design issues of these functions, so let's better not ever call them here in the first place.
 * A_PainShootSkull: Its usage here does not depend on these issues.
 * P_ExplodeMissile: New code exclusive to ZDoom.
 * FPolyObj::CheckMobjBlocking

All occurences in p_map.cpp have been left alone although most of them probably won't need the compatibility option either.

4444d3c0c5 - removed the _3DFLOOR #define because we really do not want to comment this out anymore, right? 2015-06-07 09:41:44 +02:00
Randy Heit
b2abe9d11e - Use 64-bit coordinates for a few spots in the FPathTraverse constructor and P_SightPathTraverse().
- Allow FTraceInfo::TrlaceTraverse to pass the endpoints to FPathTraverse as deltas instead of
  as absolute coordinates.

a2acc382df - added a 'block sight' line flag.
- updated UDMF spec for player class and skill amount because the old menu limits no longer apply.
- fixed: FloorAndCeiling_LowerRaise needs to consider 4 args in maps to account for the Boom compatibility hack parameter.

bb9b5ebf92 - Added a NULL pointer check to A_Fire() and copied the target to a local
variable inside A_VileAttack() so that if P_DamageMobj() destroys the
  target, the function will still have a valid pointer to it (since reading
  it from the actor's instance data invokes the read barrier, which would
  return NULL).

ad96225213 - Changed Linux to use clock_gettime for profiling instead of rdtsc. This
avoids potential erroneous results on multicore and variable speed
  processors. Windows will need to be updated accordingly.

8a3edf9716 - Added a few 'activator == NULL' checks to some ACS functions.

9a410f864f - Separated the linedef activation types into a bit mask that allows combination
of all types on the same linedef. Also added a 'first side only' flag. This
  is not usable from Hexen or Doom format maps though but in preparation of
  the UDMF format discussed here:
  http://www.doomworld.com/vb/source-ports/43145-udmf-v0-99-specification-draft-aka-textmap/
- Changed linedef's alpha property from a byte to fixed point after seeing that
  255 wasn't handled to be fully opaque.
- fixed a GCC warning in fmodsound.cpp

776d89428d - Changed D3DFB to explicitly request double buffering instead of assuming
that the drivers will treat a BackBufferCount of 0 as a request for
  double buffering.
- Fixed: Unsetting a cvar did not remove it from the list of tab
  completions.
- Added "" as a synonym for "nullimage" in SBARINFO.
- Fixed: MAKESAVESIG's stringifier in version.h did not work as expected.
  It stringified the passed macro name, not the value of the macro.
- Moved DCajunMaster off the DObject hierarchy.
- Changed DCajunMaster::getspawned into a TArray of FStrings. It was
  mysteriously being left pointing to uninitialized memory during the
  final GC at exit and crashing.
- Fixed: The code that removed hexdd.wad from the list of IWADs when
  hexen.wad was not present did not work.

997533e0c8 - Fixed: DCajunMaster::End was missing a write barrier for getspawned. The
same problem in D_DoomMain.
- Made bglobal a pointer because it was causing problems with the garbage 
  collector.

7c87465d35 - VC++ doesn't seem to like the TArray serializer so I added a workaround
to be able to save the 3dMidtex attachment info.
- Fixed: The TArray serializer needs to be declared as a friend of TArray
  in order to be able to access its fields.
- Since there are no backwards compatibility issues due to savegame version
  bumping I closed all gaps in the level flag set.
- Bumped min. Savegame version and Netgame version for 3dMidtex related
  changes.
- Changed Jump and Crouch DMFlags into 3-way switches:
  0: map default, 1: off, 2: on. Since I needed new bits the rest of
  the DMFlag bit values had to be changed as a result.
- fixed: PTR_SlideTraverse didn't check ML_BLOCKMONSTERS for sliding
  actors without MF3_NOBLOCKMONST.
- Added MAPINFO commands 'checkswitchrange' and 'nocheckswitchrange'
  that can enable or disable switch range checking globally per map.
- Changed ML_3DMIDTEX to force ML_CHECKSWITCHRANGE.
- Added a ML_CHECKSWITCHRANGE flag which allows checking whether the 
  player can actually reach the switch he wants to use.
- Made DActiveButton::EWhere global so that I can use it outside thr
  DActiveButton class.

March 17, 2008 (Changes by Graf Zahl)
- Changed P_LineOpening to pass its result in a struct instead of global
  variables.
- Added Eternity's 3DMIDTEX feature (no Eternity code used though.)
  It should be feature complete with the exception of the ML_BLOCKMONSTERS
  flag handling. That particular part of Eternity's implementation is
  sub-optimal because it hijacks an existing flag and doesn't seem to make
  much sense to me. Maybe I'll implement it as a separate flag later.
