5da2885d88 - Changed DArgs to use a TArray of FStrings instead of doing its own string vector management
in preparation for doing GatherFiles the "right" way.

51e158d7dc - added all known maps requiring inverted sprite sorting to compatibility.txt.
- added compatibility option to invert sprite sorting. Apparently Doom.exe
  originally sorted them differently than most source port and on some maps
  which depends on this it doesn't look right (e.g. Strain MAP13)

ddf1afb82b - Shift player sprites down half a pixel. Interestingly, this makes vertical
scaling much closer between software and hardware.

4ebfdac887 - Changed all coordinates for DrawTexture() to floating point so that the
player sprites will retain the same precision they had when they were
  rendered as part of the 3D view. (needed for propery alignment of flashes
  on top of weapon sprites) It worked just fine for D3D, but software
  rendering was another matter. I consequently did battle with imprecisions
  in the whole masked texture drawing routines that had previously been
  partially masked by only drawing on whole pixel boundaries. Particularly,
  the tops of posts are calculated by multiplying by spryscale, and the
  texture mapping coordinates are calculated by multiplying by dc_iscale
  (where dc_iscale = 1 / spryscale). Since these are both 16.16 fixed point
  values, there is a significant variance. For best results, the drawing
  routines should only use one of these values, but that would mean
  introducing division into the inner loop. If the division removed the
  necessity for the fudge code in R_DrawMaskedColumn(), would it be worth it?
  Or would the divide be slower than the fudging? Or would I be better off
  doing it like Build and using transparent pixel checks instead, not
  bothering with skipping transparent areas? For now, I chop off the
  fractional part of the top coordinate for software drawing, since it was
  the easiest thing to do (even if it wasn't the most correct thing to do).

vissprites.

d502655866 - For hardware 2D, apply fixed colormaps when copying to video memory instead
of doing it directly during the rendering, in order to improve visual
  fidelity for colormaps that aren't grayscale.

c285f38a02 - Fixed: When drawing with a special colormap the quad's flags weren't cleared
which could cause crashes.
- Added custom special colormaps to DECORATE.
- Cleaned up special colormap code and removed lots of dependencies on the
  knowledge of the tables' contents.

b8eb530a0d - Fixed: Wall drawing handled fixed light levels improperly (but did not
completely ignore them, either).
- Separated light level fixing out of player_t's fixedcolormap parameter.
  Using a fixed light level (e.g. PowerTorch) will no longer wipe out
  colored lighting.
- Moved the blending rectangle drawing into a separate discrete stage, since
  doing it while copying the 3D view window to the display now blends
  underneath the weapon instead of on top of it.
- Consolidated the special colormaps into a single 2D table.
- Tweaked the special colormaps slightly to make the true color results more
  closely match the paletted approximations.
- fb_d3d9_shaders.h was getting unwieldy, so I moved the shaders out of the
  executable and into zdoom.pk3. Shaders are still precompiled so I don't need
  to pull in a dependancy on D3DX.
- Added a few more shaders to accomodate drawing weapons with all the in-game
  lighting models. These are accessed with the new DrawTexture tags
  DTA_SpecialColormap and DTA_ColormapStyle.
- Player weapon sprites are now drawn using Direct3D and receive all the
  benefits thereof.

93202a5488 - Removed -fno-strict-aliasing from the GCC flags for ZDoom and fixed the
issues that caused its inclusion. Is an optimized GCC build any faster
  for being able to use strict aliasing rules? I dunno. It's still slower
  than a VC++ build.
  
  I did run into two cases where TAutoSegIterator caused intractable problems
  with breaking strict aliasing rules, so I removed the templating from it,
  and the caller is now responsible for casting the probe value from void *.
- Removed #include "autosegs.h" from several files that did not need it
  (in particular, dobject.h when not compiling with VC++).

information of all actors in the sector needs to be updated.

a732687548 - Changed APlayerPawn::DamageFade to a PalEntry from 3 floats.
- Removed #pragma warnings from cmdlib.h and fixed the places where they were 
  still triggered.
  These #pragmas were responsible for >90% of the GCC warnings that were not
  listed in VC++.
- Fixed one bug in the process: DSeqNode::m_Atten was never adjusted when the
  parameter handling of the sound functions for attenuation was changed.
  Changed m_Atten to a float and fixed the SNDSEQ parser to set proper values. 
  Also added the option to specify attenuation with direct values in addition 
  to the predefined names.

a908834a11 - added some default definitions for constants that may miss in some headers.

Christoph Oelckers
5bd3d0d37d - Fixed: skins can not be sorted for binary search because the player class
code depends on the original indices.
- Fixed: P_StartConversation set the global dialog node variable for all
  players, not just the consoleplayer.
- Fixed: AWeapon::PickupForAmmo assumed that any weapon having a secondary
  ammo type also has a primary one.

0c9f735357 - Restored the old drawseg/sprite distance check from 2.0.63. The code that
replaced it did the check at the center of the area intersected by the
  sprite and the drawseg, whereas 2.0.63 only did the check at the location
  of the sprite on the map.

Christoph Oelckers
153a2a4c2c - Fixed: G_DoPlayDemo did not free the demobuffer or the CVAR backups when it
failed to start the demo.
- Added a MF5_BRIGHT flag to always render an actor fullbright.
- Fixed: Calling Door_Animated with a non-zero tag created a new thinker
  for each two-sided line of the sector.
- Added Karate Chris's submission for making 'spray' a cheat.
- Added CO2's default parameter additions for several Doom code pointers
  submission.
- Added CO2's A_RemoveMaster/A_RemoveChildren submission.
- Added Blzut3's SBARINFO replacement for the Doom statusbar.
- Fixed: SBarInfo still displayed the wrong bar for height 0
- Added A_KillSiblings and A_DamageSiblings code pointers.
- added MaxAbsorb and MaxFullAbsorb properties for Armor.

760f70d3f1 - Changed compilation for g_doom, g_heretic, g_hexen and g_strife folders
so that all files are included by a central one instead of compiling 
  each one separately. This speeds up the compilation process by 25%
  when doing a complete rebuild in Visual C.
- Cleaned up more header dependencies.

Christoph Oelckers
f4c07c45ec - Removed DECORATE's ParseClass because it was only used to add data to fully
internal actor classes which no longer exist.
- Changed the state structure so that the Tics value doesn't need to be hacked
  into misc1 with SF_BIGTIC anymore. 
- Changed sprite processing so that sprite names are converted to indices 
  during parsing so that an additional postprocessing step is no longer needed.
- Fixed: Sprite names in DECORATE were case sensitive.
- Exported AActor's defaults to DECORATE and removed all code for the 
  internal property parser which is no longer needed.

ae54e13428 IMPORTANT NOTE: I uncommented some code depending on the missing x86.cpp file to allow this to compile, These changes must be reverted as soon as this file is added (see v_palette.cpp and win32/i_system.cpp.)
- Removed AT_GAME_SET because it's no longer used anywhere.
- Converted the last remaining global classes to DECORATE.
- Fixed: Inventory.PickupFlash requires an class name as parameter not an
  integer. Some Hexen definitions got it wrong.
- Converted Hexen's Pig to DECORATE.
- Replaced the ActorInfo definitions of all internal inventory classes with 
  DECORATE definitions.
- Added option to specify a powerup's duration in second by using a negative
  number.

dda5ddd3c2 - Ported vlinetallasm4 to AMD64 assembly. Even with the increased number of
registers AMD64 provides, this routine still needs to be written as self-
  modifying code for maximum performance. The additional registers do allow
  for further optimization over the x86 version by allowing all four pixels
  to be in flight at the same time. The end result is that AMD64 ASM is about
  2.18 times faster than AMD64 C and about 1.06 times faster than x86 ASM.
  (For further comparison, AMD64 C and x86 C are practically the same for
  this function.) Should I port any more assembly to AMD64, mvlineasm4 is the
  most likely candidate, but it's not used enough at this point to bother.
  Also, this may or may not work with Linux at the moment, since it doesn't
  have the eh_handler metadata. Win64 is easier, since I just need to
  structure the function prologue and epilogue properly and use some
  assembler directives/macros to automatically generate the metadata. And
  that brings up another point: You need YASM to assemble the AMD64 code,
  because NASM doesn't support the Win64 metadata directives.
- Added an SSE version of DoBlending. This is strictly C intrinsics.
  VC++ still throws around unneccessary register moves. GCC seems to be
  pretty close to optimal, requiring only about 2 cycles/color. They're
  both faster than my hand-written MMX routine, so I don't need to feel
  bad about not hand-optimizing this for x64 builds.
- Removed an extra instruction from DoBlending_MMX, transposed two
  instructions, and unrolled it once, shaving off about 80 cycles from the
  time required to blend 256 palette entries. Why? Because I tried writing
  a C version of the routine using compiler intrinsics and was appalled by
  all the extra movq's VC++ added to the code. GCC was better, but still
  generated extra instructions. I only wanted a C version because I can't
  use inline assembly with VC++'s x64 compiler, and x64 assembly is a bit
  of a pain. (It's a pain because Linux and Windows have different calling
  conventions, and you need to maintain extra metadata for functions.) So,
  the assembly version stays and the C version stays out.
- Removed all the pixel doubling r_detail modes, since the one platform they
  were intended to assist (486) actually sees very little benefit from them.
- Rewrote CheckMMX in C and renamed it to CheckCPU.
- Fixed: CPUID function 0x80000005 is specified to return detailed L1 cache
  only for AMD processors, so we must not use it on other architectures, or
  we end up overwriting the L1 cache line size with 0 or some other number
  we don't actually understand.

fb50df2c63 About a week's worth of changes here. As a heads-up, I wouldn't be
surprised if this doesn't build in Linux right now. The CMakeLists.txt
were checked with MinGW and NMake, but how they fair under Linux is an
unknown to me at this time.

- Converted most sprintf (and all wsprintf) calls to either mysnprintf or
  FStrings, depending on the situation.
- Changed the strings in the wbstartstruct to be FStrings.
- Changed myvsnprintf() to output nothing if count is greater than INT_MAX.
  This is so that I can use a series of mysnprintf() calls and advance the
  pointer for each one. Once the pointer goes beyond the end of the buffer,
  the count will go negative, but since it's an unsigned type it will be
  seen as excessively huge instead. This should not be a problem, as there's
  no reason for ZDoom to be using text buffers larger than 2 GB anywhere.
- Ripped out the disabled bit from FGameConfigFile::MigrateOldConfig().
- Changed CalcMapName() to return an FString instead of a pointer to a static
  buffer.
- Changed startmap in d_main.cpp into an FString.
- Changed CheckWarpTransMap() to take an FString& as the first argument.
- Changed d_mapname in g_level.cpp into an FString.
- Changed DoSubstitution() in ct_chat.cpp to place the substitutions in an
  FString.
- Fixed: The MAPINFO parser wrote into the string buffer to construct a map
  name when given a Hexen map number. This was fine with the old scanner
  code, but only a happy coincidence prevents it from crashing with the new
  code
- Added the 'B' conversion specifier to StringFormat::VWorker() for printing
  binary numbers.
- Added CMake support for building with MinGW, MSYS, and NMake. Linux support
  is probably broken until I get around to booting into Linux again. Niceties
  provided over the existing Makefiles they're replacing:
  * All command-line builds can use the same build system, rather than having
    a separate one for MinGW and another for Linux.
  * Microsoft's NMake tool is supported as a target.
  * Progress meters.
  * Parallel makes work from a fresh checkout without needing to be primed
    first with a single-threaded make.
  * Porting to other architectures should be simplified, whenever that day
    comes.
- Replaced the makewad tool with zipdir. This handles the dependency tracking
  itself instead of generating an external makefile to do it, since I couldn't
  figure out how to generate a makefile with an external tool and include it
  with a CMake-generated makefile. Where makewad used a master list of files
  to generate the package file, zipdir just zips the entire contents of one or
  more directories.
- Added the gdtoa package from netlib's fp library so that ZDoom's printf-style
  formatting can be entirely independant of the CRT.

Christoph Oelckers
8ca7c05e9d - Changed FImageCollection to return translated texture indices so
that animated icons can be done with it.
- Changed FImageCollection to use a TArray to hold its data.
- Fixed: SetChanHeadSettings did an assignment instead of comparing
  the channel ID witg CHAN_CEILING.
- Changed sound sequence names for animated doors to FNames.
- Automatically fixed: DCeiling didn't properly serialize its texture id.
- Replaced integers as texture ID representation with a specific new type
  to track down all potentially incorrect uses and remaining WORDs used
  for texture IDs so that more than 32767 or 65535 textures can be defined.


SVN r1036 (trunk)
2008-06-15 18:36:26 +00:00
Randy Heit
9e42cdaf08 - Replaced the naive area sound implementation with one that takes into
consideration the size and shape of the sector producing the sound. See
  the lifts on Doom 2 MAP30 and compare with previous versions.
- Fixed: The stop sound for sector-based sound sequences was not played with
  the CHAN_AREA flag.
- Removed the distinction between S_Sound() and S_SoundID() functions. Use
  S_Sound() for both names and IDs from now on.


SVN r1034 (trunk)
2008-06-15 02:25:09 +00:00
Randy Heit
a0d5463b49 - Added the C99 printf size specifiers 't' (ptrdiff_t) and 'z' (size_t) to
FString::Format() so that I can fix all the problem printf strings that a
  64-bit GCC compile finds.



SVN r968 (trunk)
2008-05-14 03:39:30 +00:00
Randy Heit
1f8e471eba - Separated the skin scale values into separate X and Y values so that skins
automatically generated for different player classes can use both the
  scaling values that can be set for the actor.


SVN r947 (trunk)
2008-04-27 22:33:19 +00:00
Christoph Oelckers
e105a29e99 - Externalized all default episode definitions. Added an 'optional' keyword
to handle M4 and 5 in Doom and Heretic.
- Added P_CheckMapData functions and replaced all calls to P_OpenMapData that
  only checked for a map's presence with it.
- Added Martin Howe's player statusbar face submission.
- Added an 'adddefaultmap' option for MAPINFO. This is the same as 'defaultmap'
  but keeps all existing information in the default and just adds to it. This
  is needed because Hexen and Strife set some information in their base
  MAPINFO and using 'defaultmap' in a PWAD would override that.
- Fixed: Using MAPINFO's f1 option could cause memory leaks.
- Added option to load lumps by full name to several places:
  * Finale texts loaded from a text lump
  * Demos
  * Local SNDINFOs
  * Local SNDSEQs
  * Image names in FONTDEFS
  * intermission script names
- Changed the STCFN121 handling. The character is not an 'I' but a '|' so
  instead of discarding it it should be inserted at position 124.
- Renamed indexfont.fon to indexfont so that I could remove a special case
  from V_GetFont that was just added for this one font.
- Added a 'dumpspawnedthings' CVAR that enables a listing of all things in 
  the map and the actor type they spawned.

Randy Heit
d2c275bbb3 - Changed FScanner so that opening a lump gives the complete wad+lump name
rather than a generic one, so identifying errors among files that all have
  the same lump name no longer involves any degree of guesswork in
  determining exactly which file the error occurred in.
- Added a check to S_ParseSndSeq() for SNDSEQ lumps with unterminated final
  sequences.
- Fixed: Parts of s_sndseq.cpp that scan the Sequences array need NULL
  pointer checks, in case an improper sequence was encountered during
  parsing but not early enough to avoid creating a slot for it in the array.


SVN r874 (trunk)
2008-04-03 03:19:21 +00:00
Christoph Oelckers
d5c3693fd9 - Added SnowKate709's A_DamageMaster/A_DamageChildren patch.
- Added a SFX_TRANSFERAMBUSHFLAG for A_SpawnItemEx.
- Added "Shaded" as a valid parameter for DECORATE's RenderStyle.
- Added Karate Chris's patch for a MAPINFO option making Strife conversations
  not halt the game.
- Extended the $limit fix that $alias and $random definitions can have their
  own $limit now.
- Fixed: When resolving a linked sound the limit of the current sound was
  ignored and the one of the referenced sound being used. This was particularly
  noticable when using the chaingun in a group of Zombiemen.
- Added a namespc parameter to FWadCollection::CheckNumForFullName which is
  used when a normal lump name has to be looked up and changed all
  CheckNumForFullName/CheckNumForName combinations in the source to use
  the extended version of CheckNumForFullName only to have consistent
  behavior for lump name lookup.

f2660dc336 - Merged the GC branch back into the trunk, so now it can receive more
testing from the people who download SVN trunk builds.

Randy Heit
e5572a1c4e - Updated lempar.c to v1.31.
- Added .txt files to the list of types (wad, zip, and pk3) that can be
  loaded without listing them after -file.
- Fonts that are created by the ACS setfont command to wrap a texture now
  support animated textures.
- FON2 fonts can now use their full palette for CR_UNTRANSLATED when drawn
  with the hardware 2D path instead of being restricted to the game palette.
- Fixed: Toggling vid_vsync would reset the displayed fullscreen gamma to 1
  on a Radeon 9000.
- Added back the off-by-one palette handling, but in a much more limited
  scope than before. The skipped entry is assumed to always be at 248, and
  it is assumed that all Shader Model 1.4 cards suffer from this. That's
  because all SM1.4 cards are based on variants of the ATI R200 core, and the
  RV250 in a Radeon 9000 craps up like this. I see no reason to assume that
  other flavors of the R200 are any different. (Interesting note: With the
  Radeon 9000, D3DTADDRESS_CLAMP is an invalid address mode when using the
  debug Direct3D 9 runtime, but it works perfectly fine with the retail
  Direct3D 9 runtime.) (Insight: The R200 probably uses bytes for all its
  math inside pixel shaders. That would explain perfectly why I can't use
  constants greater than 1 with PS1.4 and why it can't do an exact mapping to
  every entry in the color palette.
- Fixed: The software shaded drawer did not work for 2D, because its selected
  "color"map was replaced with the identitymap before being used.
- Fixed: I cannot use Printf to output messages before the framebuffer was
  completely setup, meaning that Shader Model 1.4 cards could not change
  resolution.
- I have decided to let remap palettes specify variable alpha values for
  their colors. D3DFB no longer forces them to 255.
- Updated re2c to version 0.12.3.
- Fixed: A_Wander used threshold as a timer, when it should have used
  reactiontime.
- Fixed: A_CustomRailgun would not fire at all for actors without a target
  when the aim parameter was disabled.
- Made the warp command work in multiplayer, again courtesy of Karate Chris.
- Fixed: Trying to spawn a bot while not in a game made for a crashing time.
  (Patch courtesy of Karate Chris.)
- Removed some floating point math from hu_scores.cpp that somebody's GCC
  gave warnings for (not mine, though).
- Fixed: The SBarInfo drawbar command crashed if the sprite image was
  unavailable.
- Fixed: FString::operator=(const char *) did not release its old buffer when
  being assigned to the null string.
- The scanner no longer has an upper limit on the length of strings it
  accepts, though short strings will be faster than long ones.
- Moved all the text scanning functions into a class. Mainly, this means that
  multiple script scanner states can be stored without being forced to do so
  recursively. I think I might be taking advantage of that in the near
  future. Possibly. Maybe.
- Removed some potential buffer overflows from the decal parser.
- Applied Blzut3's SBARINFO update #9:
  * Fixed: When using even length values in drawnumber it would cap to a 98
    value instead of a 99 as intended.
  * The SBarInfo parser can now accept negatives for coordinates. This
    doesn't allow much right now, but later I plan to add better fullscreen
    hud support in which the negatives will be more useful. This also cleans
    up the source a bit since all calls for (x, y) coordinates are with the
    function getCoordinates().
- Added support for stencilling actors.
- Added support for non-black colors specified with DTA_ColorOverlay to the
  software renderer.
- Fixed: The inverse, gold, red, and green fixed colormaps each allocated
  space for 32 different colormaps, even though each only used the first one.
- Added two new blending flags to make reverse subtract blending more useful:
  STYLEF_InvertSource and STYLEF_InvertOverlay. These invert the color that
  gets blended with the background, since that seems like a good idea for
  reverse subtraction. They also work with the other two blending operations.
- Added subtract and reverse subtract blending operations to the renderer.
  Since the ERenderStyle enumeration was getting rather unwieldy, I converted
  it into a new FRenderStyle structure that lets each parameter of the
  blending equation be set separately. This simplified the set up for the
  blend quite a bit, and it means a number of new combinations are available
  by setting the parameters properly.

a9dc8ddce3 - Fixed: Weapon positions were only adjusted in 1280x1024 if the status
bar was hidden.
- Fixed: If you died in co-op and somebody else ended the map before you
  respawned, you would start the next map with only default inventory, no
  matter what dmflags was set to.

1acc3d00c4 - Discovered that Shader Model 1.4 clamps my constants, so I can't use
palettes smaller than 256 entries with the shader I wrote for it. Is there
  a list of gotchas like this listed some where? I'd really like to see it.
  
  Well, when compiled with SM2.0, the PalTex shader seems to be every-so-
  slightly faster on my GF7950GT than the SM1.4 version, so I guess it's a
  minor win for cards that support it.
- Fixed: ST_Endoom() failed to free the bitmap it used.
- Added the DTA_ColorOverlay attribute to blend a color with the texture
  being drawn. For software, this (currently) only works with black. For
  hardware, it works with any color. The motiviation for this was so I could
  rewrite the status bar calls that passed DIM_MAP to DTA_Translation to
  draw darker icons into something that didn't require making a whole new
  remap table.
- After having an "OMG! How could I have been so stupid?" moment, I have
  removed the off-by-one check from D3DFB. I had thought the off-by-one error
  was caused by rounding errors by the shader hardware. Not so. Rather, I
  wasn't sampling what I thought I was sampling. A texture that uses palette
  index 255 passes the value 1.0 to the shader. The shader needs to adjust the
  range of its palette indexes, or it will end up trying to read color 256
  from the palette texture when it should be reading color 255. Doh!
- The TranslationToTable() function has been added to map from translation
  numbers used by actors to the tables those numbers represent. This function
  performs validation for the input and returns NULL if the input value
  is invalid.
- Major changes to the way translation tables work: No longer are they each a
  256-byte array. Instead, the FRemapTable structure is used to represent each
  one. It includes a remap array for the software renderer, a palette array
  for a hardware renderer, and a native texture pointer for D3DFB. The
  translationtables array itself is now an array of TArrays that point to the
  real tables. The DTA_Translation attribute must also be passed a pointer
  to a FRemapTable, not a byte array as previously.
- Modified DFrameBuffer::DrawRateStuff() so that it can do its thing properly
  for D3DFB's 2D mode. Before, any fullscreen graphics (like help images)
  covered it up.

faa9cc4302 - added a P_PointInSector function and replaced all calls to retrieve an
actor's sector in the game engine code with it. This way there's a clear
  distinction between renderer-specific and game-specific calls.

50f75b6e8a - Fixed: deadthings.txt contained a superfluous ';' which created parsing errors
with my changed code.
- Cleaned up DECORATE parser a little - moved the old style parsing code into its 
  own file and rearranged a few things.
- Made ProcessStates non-static so that it doesn't need to be passed as an argument
  to all functions in the DECORATE parser.
- Moved DECORATE parser files into their own subdirectory.
- Optimization: SC_GetToken no longer sets sc_name for identifiers. In most cases
  this creates needless overhead by adding a potentially unneeded name to the name
  table and looking up the name. In almost all cases where a name is needed it's as
  easy to assign sc_String to the name variable.
- Added enum definitions to DECORATE.

e08da03a3d - Increased precision of texture scaling factors to full fixed point. In the process
I got rid of the old tx and ty CVARs because they made the texture scaling
  much more complicated than it was actually needed (and besides, they were completely
  useless except for testing purposes anyway.)
