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.

pieces.
- Added DECORATE conversions for Hexen's Fighter weapons by Karate Chris.
- Added aWeaponGiver class to generalize the standing AssaultGun.
- converted a_Strifeweapons.cpp to DECORATE, except for the Sigil.
SVN r1129 (trunk)
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.
SVN r1082 (trunk)
- added an abstract base class for special map spots that are maintained in
lists and rewrote the boss brain, the mace and DSparil to use it.
- fixed: RandomSpawners didn't destroy themselves after finishing their work.
SVN r1076 (trunk)
- Added a generalized version of Skulltag's A_CheckRailReload function.
- Fixed: DrawImage didn't take 0 as a valid image index.
- Added Gez's RandomSpawner submission with significant changes.
- Added optional blocks for MAPINFO map definitions. ZDoom doesn't use
this feature itself but it allows other ports based on ZDoom
to implement their own sets of options without making such a MAPINFO
unreadable by ZDoom.
SVN r1044 (trunk)
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)
any zone you want.
- Using a too-recent version of FMOD now gives an error, since there may be
breaking changes to the API from one version to the next (excluding
revisions in stable branches, which only represent bug fixes).
- Updated fmod_wrap.h for FMOD 4.16 and corrected a bug that had gone
unnoticed before: The delayhi and delaylo parameters for Channel::setDelay()
and getDelay() were swapped.
SVN r1032 (trunk)
They are not needed anywhere else.
- Changed the HackHack hack for corrupt 256 pixel high textures that
FMultiPatchTexture only calls a virtual function instead of doing any
type checks of the patch itself.
- Cleaned up the constant definitions in doomdata.h.
- Moved the TEXTUREx structures from doomdata.h to multipatchtexture.cpp
because they are used only in this one file.
- Removed some more typedefs from r_defs.h and doomdata.h
- Moved local polyobject data definitions from p_local.h to po_man.cpp.
SVN r1012 (trunk)
into a single place.
- Fixed: Setting an invalid mug shot state crashed the game.
- Fixed my attempts to be clever with strings yesterday.
SVN r1009 (trunk)
texture definitions. HIRESTEX is still supported but deprecated.
- Removed all 16 bit values from texture manager.
- Changed: The texture manager now sorts all textures for a WAD by type
to avoid priority issues with HIRESTEX defined textures.
- Changed sidedef flag WALLF_ADDTRANS into a linedef flag because it is
always the same for both sides of a linedef. This also makes handling
this in the UDMF parser easier because the linedef parsing function does
not need to access the sidedef data.
- Added new ZDoom specific UDMF linedef and sidedef properties to map parser.
- Added new ZDoom specific UDMF sector properties to map parser.
- Added class definitions for new interpolators that are better
equipped to interact with the interpolated objects.
- Separated interpolation code into its own file r_interpolate.cpp.
- Added some simple customization options to the end game screens.
- Fixed: Polyobject detection in the internal node builder did not work
anymore due to some code rearrangement for UDMF map loading. To keep
it compatible between all map formats the THINGS lump of binary format
maps must be loaded before building the nodes. This also means that
the spawning itself can be done in the same function for all map types
(except Build) now.
- Changed 'Smooth mouse movement' menu option from m_filter to smooth_mouse
which is more what would be expected from this option.
- Fixed: Weapons and ammo items that were modified by Dehacked gave full
ammo when being dropped by monsters. To properly handle this the
handling of spawning Dehacked modified pickups was changed to use
the DECORATE replacement feature instead of hacking the spawn state
of the original item and calling a spawn function from there.
SVN r1001 (trunk)
heavily customized version of DUMB (Dynamic Universal Music Bibliotheque).
It has been slightly modified by me:
* Added support for Ogg Vorbis-compressed samples in XM files ala FMOD.
* Removed excessive mallocs from the replay core.
* Rerolled the loops in resample.c. Unrolling them made the object file
~250k large while providing little benefit. Even at ~100k, I think it's
still larger than it ought to be, but I'll live with it for now.
Other than that, it's essentially the same thing you'd hear in foobar2000,
minus some subsong detection features. Release builds of the library look
like they might even be slightly faster than FMOD, which is a plus.
- Fixed: Timidity::font_add() did not release the file reader it created.
- Fixed: The SF2 loader did not free the sample headers in its destructor.
SVN r995 (trunk)
of type MiscPatch with the same name.
- Added UDMF line trigger types MonsterUse and MonsterPush.
- Separated skill and class filter bits from FMapThing::flags so that
UDMF can define up to 16 of each. Also separated easy/baby and
hard/nightmare and changed default MAPINFO definitions.
- Changed: Crosshair drawing uses the current player class's default health instead
of 100 to calculate the color for the crosshair.
- Added SECF_NOFALLINGDAMAGE flag plus Sector_ChangeFlags to set it. Also separated
all user settable flags from MoreFlags into their own Flags variable.
SVN r964 (trunk)
- Added very basic Soundfont support to the internal TiMidity. Things missing:
filter, LFOs, modulation envelope, chorus, reverb, and modulators. May or
may not be compatible with TiMidity++'s soundfont extensions.
- Added support for quoted strings to the TiMidity config parser.
SVN r957 (trunk)
3D panning.
- The listener's velocity is now set at 0 for the sound engine. The player
moves so fast that you can hear the doppler shift just by running around,
otherwise.
- Changed the sound code so that all sounds that start playing on a single
tic actually start playing at the exact same sample position.
SVN r927 (trunk)
rid of timidity/tables.cpp, which conflicts in name with the main Doom
tables.cpp. (And interestingly, VC++ automatically renamed the object file,
so I wasn't aware of the problem with GCC.)
SVN r902 (trunk)
channel when restarting the song, rather than emitting a single note off
event which only has a 1 in 127 chance of being for a note that's playing
on that channel. Then I decided it would probably be a good idea to reset
all the controllers as well.
- Increasing the size of the internal Timidity stream buffer from 1/14 sec
(copied from the OPL player) improved its sound dramatically, so apparently
Timidity has issues with short stream buffers. It's now at 1/2 sec in
length. However, there seems to be something weird going on with
corazonazul_ff6boss.mid near the beginning where it stops and immediately
restarts a guitar on the exact same note.
- Added a new sound debugging cvar: snd_drawoutput, which can show various
oscilloscopes and spectrums.
- Internal TiMidity now plays music.
- Changed the progdir global variable into an FString.
SVN r900 (trunk)
freed and each iterator allocated a new one as a result.
- Split the Xlat parser context class into a generic part that can be
used for other Lemon-based parsers in the future and a smaller
Xlat-specific part.
SVN r892 (trunk)
can be played as OPL can also be dumped.
- Removed the opl_enable cvar, since OPL playback is now selectable as just
another MIDI device.
- Added support for DRO playback and dual-chip RAW playback.
- Removed MUS support from OPLMUSSong, since using the OPLMIDIDevice with
MUSSong2 works just as well. There are still lots of leftover bits in
the class that should probably be removed at some point, too.
- Added dual-chip dumping support for the RAW format.
- Added DosBox Raw OPL (.DRO) dumping support. For whatever reason,
in_adlib calculates the song length for this format wrong, even though
the exact length is stored right in the header. (But in_adlib seems buggy
in general; too bad it's the only Windows version of Adplug that seems to
exist.)
- Rewrote the OPL dumper to work with MIDI as well as MUS.
SVN r872 (trunk)
advanced sound options menu. Removed opl_enable from the menu.
- Added OPL synth as MIDI device -3. Since this is based on the MUS player
code, it only supports those events and controllers supported by MUS.
Some of Duke's MIDIs sound awful, but I think that may be more because
it's using different instruments... There's a thread in the MIDI streamer
class that could be taken out for Linux, since it doesn't need to deal
with the Windows Multimedia API, but for now, this is still Windows-only.
SVN r864 (trunk)
- Added a debuganimated CCMD that can be used to output some information
if a WAD shows broken animations.
- Fixed: The handling for enum values in Xlat was incorrect. The rule with
value assignment must set the counter one higher than the current value.
- Fixed: The definition of enums in the Xlat grammar was right-recursive
which could create stack overflows in the parser. Made it left-recursive as
recommended in Lemon's docs.
SVN r850 (trunk)
xlat_parser.y because both files had the same time stamp after an update,
and Lemon only rewrites the header file if it's changed.
- Added $volume SNDINFO command. This is multiplied with the volume the sound
is played at to arrive at the final volume (before distance attenuation).
- Added the CHAN_AREA flag to disable 3D panning within the min distance of a
sound. Sector sound sequences (except doors) use this flag.
- Added the CHAN_LOOP flag to replace the S_Looped* sound functions.
- Restored the sound limiting.
SVN r849 (trunk)
- Changed savegame versioning so that the written version is never lower
than the minmum one reported as compatible.
- Added mirrored movement modes for linked sectors.
- Added Eternity-style initialization for linked sectors as a new subtype
of Static_Init.
- Added linked sectors. The control sector determines how they move but if
any one of the linked sectors is blocked, movement for all linked sectors
will be affected. This will allow lifts consisting out of more than one
sector without the risk of breaking them if only one of the sectors is
blocked.
- Fixed: A_Mushroom created an actor on the stack.
SVN r825 (trunk)
- deleted src/xlat/xlat_parser.c from the repository. Its content depend on the directory
directory structure it is generated in and it gets recreated each time the project is
compiled (why?) so it'd be changed with each SVN commit. VC++ doesn't seem to mind if
it can't be found so I think it's better this way.
SVN r822 (trunk)
- Fixed: ACS SetMugShotState needs to check the StatusBar pointer for the
proper object type.
- Move SBarInfo loading code in d_main.cpp into a static method of DSBarInfo.
- Removed dobject.err from the repository. It only contained a list of compiler
errors for some very old version of dobject.cpp.
- Fixed: A_JumpIfCloser was missing a z-check.
- Added Blzut3's SBARINFO update #13:
- Split sbarinfo.cpp into two files sbarinfo_display.cpp and sbarinfo_parser.cpp
- Rewrote the mug shot system for SBarInfo to allow for scripting and custom
states for different means of death.
- SBarInfo now loads all SBarInfo lumps instead of just the last one. Clashing
status bar definitions will now be cleared before the bar is read.
- Fixed: When using transparency with bars the new drawing method (bg over fg)
didn't work. In the case that the border value is set to 0 it will revert to
the old method (fg over bg).
- Fixed: drawbar lost any high res information it was given.
- Added: ACS command SetMugShotState(str state) which sets the mug shot state
for the activating player.
- Added: keepoffsets flag to drawbar. When set the offsets in the fg image will
also be applied when displaying the bar.
SVN r812 (trunk)
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.
SVN r810 (trunk)
spc_amp from a x.4 fixed point number to a normal float.
- Switched SPC playback from the external SNESAPU.DLL to Blargg's LGPL
snes_spc library. I've compiled it with the fast DSP rather than the
highly accurate one, since I didn't notice a meaningful difference between
the two in my limited testing. In short: SPC playback is now built in to
ZDoom. You don't need to download anything extra to make it work, and it
also works on Linux as well as Windows (though building with Linux is
currently untested).
- Fixed: Stereo separation was calculated very wrongly when in 2D sound mode.
SVN r794 (trunk)
for FMOD Ex while at the same time removing support for FMOD 3. Be sure to update
your SDKs. GCC users, be sure to do a "make cleandep && make clean" before
building, or you will likely get inexplicable errors.
- Fixed: If you wanted to make cleandep with MinGW, you had to specifically
specify Makefile.mingw as the makefile to use.
- Added a normalizer to the OPL synth. It helped bring up the volume a little,
but not nearly as much as I would have liked.
- Removed MIDI Mapper references. It doesn't work with the stream API, and
it doesn't really exist on NT kernels, either.
- Reworked music volume: Except for MIDI, all music volume is controlled
through GSnd and not at the individual song level.
- Removed the mididevice global variable.
- Removed snd_midivolume. Now that all music uses a linear volume scale,
there's no need for two separate music volume controls.
- Increased snd_samplerate default up to 48000.
- Added snd_format, defaulting to "PCM-16".
- Added snd_speakermode, defaulting to "Auto".
- Replaced snd_fpu with snd_resampler, defaulting to "Linear".
- Bumped the snd_channels default up from a pitiful 12 to 32.
- Changed snd_3d default to true. The new cvar snd_hw3d determines if
hardware 3D support is used and default to false.
- Removed the libFLAC source, since FMOD Ex has native FLAC support.
- Removed the altsound code, since it was terribly gimped in comparison to
the FMOD code. It's original purpose was to have been as a springboard for
writing a non-FMOD sound system for Unix-y systems, but that never
happened.
- Finished preliminary FMOD Ex support.
SVN r789 (trunk)
it seems to have a working volume control.
- Renamed music_midi_stream.cpp to music_midi_base.cpp.
- Moved the WinMM MIDI code into a new container class.
SVN r787 (trunk)
class so they all the low-level details of MIDI streaming are kept in
one place.
- Converted the SMF MIDI playback to use the same MIDI streams as MUS
playback.
- Moved MUS playback back into its own thread so that it can continue
uninterrupted if the main thread is too busy to service it in a timely
manner.
- Fixed: The MEVT_* values are not defined shifted into their spot for a
MIDIEVENT, so I need to do it myself.
- Fixed: Pausing a MUS and the changing snd_midivolume caused the paused
notes to become audible.
SVN r784 (trunk)
- Got rid of R_InitPatches because the new texture init code needs to preload
everything to work correctly.
- Rewrote texture manager initialization to order textures primarily by WAD
rather than by type. This way later textures will always override earlier
ones. The only exception is that TEX_MiscPatch are only used as a fallback
if nothing else can be found.
- Optimized the tryany case of FTextureManager::CheckForTexture. It is not
necessary to scan the hash chain twice. The required information can be
retrieved during the first pass as easily and even offers a little more
control.
- Made FFont destructor virtual.
- Added 'Ice' translation to DECORATE.
(Caution: Not fully tested yet!)
SVN r715 (trunk)
error handling.
- Fixed: dehsupp/scanner.re defined "}" as the token RPAREN. dehsupp/parse.y
also defined action_list_def as needing a RBARCE. I'm surprised it worked
at all before. I guess Lemon really was too accepting.
- Changed the way that xlatcc handles include statements so that I don't need
to modify the logic of lempar.c. I also discovered that the grammar was
improperly defined and only accepted the first statement. It worked before
because Lemon used to accept multiple times before reaching the EOF token.
I have also verified that it is still generating the proper lumps.
- Removed some unused wadsrc files from the repository.
- Fixed my re2c upgrade.
- Updated lemon.c to v1.53.
SVN r711 (trunk)
- 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.
SVN r710 (trunk)
truncate the coordinates to integers before sending them to the hardware.
Otherwise, there can be one pixel gaps compared to the software renderer,
because the hardware is rounding to nearest but the software renderer is
simply truncating the fractional part of the coordinate. This is the real
cause of the gap above the status bar at 1152x864 (and another gap to the
left of the status bar at 800x500).
- Fixed: When D3DFB::DrawTextureV had to clip a tile, it adjusted the
texture coordinates erroneously, still using the old calculations from
before texture packing was implemented.
SVN r695 (trunk)
will also double as the pistol's icon in the AltHUD.
- Added a generic log display that can show Strife's log messages in all games
regardless of the current game, active status bar and HUD mode.
- Added GZDoom's alt HUD.
SVN r693 (trunk)
a long-abandoned experiment to write directly to video memory instead of
to a temporary buffer in system meroy.
- Added Direct3D versions of the melt and burn screenwipes.
- Fixed the strip sizes for the melt screenwipe to match what Doom would have
produced on a 320x200 screen, rather than producing more, thinner strips
for wider screens.
SVN r659 (trunk)
- Moved the common code of ACS and DECORATE translation generation into the
FRemapTable class.
- Fixed: The DECORATE translation code was not changed for the new data structures.
- Expanded range of ACS and DECORATE translations to 65535.
- Fixed: R_CopyTranslation was not altered for the new functionality.
I removed the function and replaced the one use with a simple assignment.
SVN r644 (trunk)
They are not actually drawn with it yet, nor is it complete, but it's
something to start with.
- Split up DCanvas::DrawTexture() into more pieces to make it easier to
virtualize.
- Removed support for non-32-bit palette textures from D3DFB. What kind of
card supports pixel shaders but not 32-bit textures?
SVN r605 (trunk)
- Updated project files for nasm 2.0, which is now named nasm.exe for the
Windows version, rather than nasmw.exe. Also fixed the annoying new warnings
it generated.
SVN r593 (trunk)
or scripts. ColorSetter (#9038) sets the sector's color and FadeSetter (#9039)
sets the fog color.
- added new flags MF5_ALWAYSFAST and MF5_NEVERFAST. These flags unconditionally
enable or disable fast movement logic, regardless of skill settings.
- added an abstraction layer for skill related settings. This is a preparation
for implementing custom skill definitions but right now all it does is
returning the original values but keeping the related information all in one

no longer gets in the way of the main parser.
- Changed A_MissileAttack, A_MeleeAttack and A_ComboAttack so that they use
metadata. Now all the hack code associated with these functions can be removed.
SVN r538 (trunk)
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.
SVN r537 (trunk)
powerup.
- Changed: Weapons are no longer checked for the EXTREMEDEATH and NOEXTREMEDEATH flags.
For all damage related actions it will always be the projectile (or puff for hitscan
attacks) that is treated as the damage inflictor.
- Fixed: Hexen's fourth weapons made extreme death depend on the weapon the player
is holding, not the projectile that did the kill. The WIF_EXTREME_DEATH flag
no longer exists as a result.
- Expanded PowerSpeed so that subclasses can be derived that alter the speed factor.
- Added an MF5_USESPECIAL flag that allows using things to execute their specials.
- added MF4_FORCERADIUSDMG flag so that exploding items can be created which
are able to hurt boss monsters.
- moved ML_BLOCK_PLAYERS to the value 0x4000 to bring it in line with Skulltag's
implementation.
SVN r530 (trunk)
.rtext files in the assembly object files. Now I can avoid doing this at
runtime, which means that ZDoom is now UPX-compatible if anyone wants to
pack it.
You will need to do a rebuild or manually delete the old assembly .obj files
for the first build from this revision to succeed, since there are no
changes to the assembly files themselves, and the build process will not be
able to automatically detect that they need to be rebuilt.
SVN r473 (trunk)
when a == 0x80000000, because the result of abs will still be negative as
long as we use signed math.
- Fixed: SafeDivScale31 performed DivScale32 instead.
- Fixed: R_DrawSpanP_ASM had a short jump into a different section.
SVN r472 (trunk)
3 new code pointers without general use it was necessary to handle
GiveDefaultInventory consistently for all players without the need to
subclass this function.
- Added a Player.RunHealth property to expose the StrifePlayer's behavior of
not being able to run when its health is below 10.
- Changed APlayerPawn::GiveDefaultInventory so that it always adds a HexenArmor
and a BasicArmor item to the inventory. If these items are not the first ones
added to the inventory anything else that might absorb damage is not guaranteed
to work consistently because their function depends on the order in the inventory.
- Changed handling of APowerup's DoEffect so that it is called from the owner's
Tick function, not the item's. This is so that the order of execution is
determined by the order in the inventory. When done in the item's Tick function
order depends on the global thinker table which can cause problems with the
order in which conflicting powerups apply their effect. Now it is guaranteed
that the item that was added to the inventory first applies its effect last.
- Fixed: Added checks for Speed==0 to A_Tracer and A_Tracer2 because this could
cause a divide by zero.
- Fixed: P_MoveThing must also set the moved actor's previous position to
prevent interpolation of the move.
- Fixed: APowerInvisibility and its subclasses need to constantly update
the owner's translucency information in case of interference between different
subclasses. Also changed Hexen's Cleric's invulnerability mode to disable
the translucency effect if an invisibility powerup is active.
SVN r448 (trunk)
both named item.
- Switched ddraw.dll to be delay loaded. With D3D9 now being the default
display code, this avoids wasting time loading DDraw if it isn't needed.
- Fixed: The Win32 I_FatalError() did not set alreadyThrown, so it could get
stuck in an endless fatal error loop.
SVN r433 (trunk)
- Renamed the new armor properties to use the same names as Skulltag to avoid
confusion. They still don't need a separate base class as in Skulltag though.
- Added Skulltag-type armor bonus that increases the max amount that can be given
by other armor items.
- Separated all armor related code from a_pickups.cpp into a_armor.cpp.
SVN r427 (trunk)
warnings. At first, I was going to try and clean them all up. Then I decided
that was a worthless cause and went about just acting on the ones that
might actually be helpful:
C4189 (local variable is initialized but not referenced)
C4702 (unreachable code)
C4512 (assignment operator could not be generated)
SVN r420 (trunk)
be surprised if it doesn't work.
- Reorganized the network startup loops so now they are event driven. There is
a single function that gets called to drive it, and it uses callbacks to
perform the different stages of the synchronization. This lets me have a nice,
responsive abort button instead of the previous unannounced hit-escape-to-
abort behavior, and I think the rearranged code is slightly easier to
understand too.
- Increased the number of bytes for version info during D_ArbitrateNetStart(),
in preparation for the day when NETGAMEVERSION requires more than one byte.
- I noticed an issue with Vista RC1 and the new fatal error setup. Even after
releasing a DirectDraw or Direct3D interface, the DWM can still use the
last image drawn using them when it composites the window. It doesn't always
do it but it does often enough that it is a real problem. At this point, I
don't know if it's a problem with the release version of Vista or not.
After messing around, I discovered the problem was caused by ~Win32Video()
hiding the window and then having it immediately shown soon after. The DWM
kept an image of the window to do the transition effect with, and then when
it didn't get a chance to do the transition, it didn't properly forget about
its saved image and kept plastering it on top of everything else
underneath.
- Added a network synchronization panel to the window during netgame startup.
- Fixed: PClass::CreateDerivedClass() must initialize StateList to NULL.
Otherwise, classic DECORATE definitions generate a big, fat crash.
- Resurrected the R_Init progress bar, now as a standard Windows control.
- Removed the sound failure dialog. The FMOD setup already defaulted to no
sound if initialization failed, so this only applies when snd_output is set
to "alternate" which now also falls back to no sound. In addition, it wasn't
working right, and I didn't feel like fixing it for the probably 0% of users
it affected.
- Fixed: The edit control used for logging output added text in reverse order
on Win9x.
- Went back to the roots and made graphics initialization one of the last
things to happen during setup. Now the startup text is visible again. More
importantly, the main window is no longer created invisible, which seems
to cause trouble with it not always appearing in the taskbar. The fatal
error dialog is now also embedded in the main window instead of being a
separate modal dialog, so you can play with the log window to see any
problems that might be reported there.
Rather than completely restoring the original startup order, I tried to
keep things as close to the way they were with early graphics startup. In
particular, V_Init() now creates a dummy screen so that things that need
screen dimensions can get them. It gets replaced by the real screen later
in I_InitGraphics(). Will need to check this under Linux to make sure it
didn't cause any problems there.
- Removed the following stubs that just called functions in Video:
- I_StartModeIterator()
- I_NextMode()
- I_DisplayType()
I_FullscreenChanged() was also removed, and a new fullscreen parameter
was added to IVideo::StartModeIterator(), since that's all it controlled.
- Renamed I_InitHardware() back to I_InitGraphics(), since that's all it's
initialized post-1.22.
SVN r416 (trunk)
monsters
- Added velocity multiplicators to A_SpawnDebris.
- Changed: A_JumpIfNoAmmo should have no effect for CustomInventory items.
- Fixed: DECORATE jump commands must set the call state's result to 0
even when they have to return prematurely.
- Added obituaries for Strife's and Hexen's monsters.
- Converted Strife's Bishop to DECORATE.
- Added momx, momy and momz variables to the DECORATE expression evaluator.
SVN r404 (trunk)
- Added DECORATE support for setting an actor's args. If this is done
it will also disable the actor's special that can be set in a map. This
is for actors that want to use A_CountdownArg or similar functions
that use the args for something different than the special's parameters.
- Converted a_sharedmisc.cpp to DECORATE.
- Added a new NActorIterator that can search for classes specified by name.
- Added a new constructor to TThinkerIterator that can search
for DECORATE defined subclasses that are not represented by a real C++ class.
- Fixed: BuildInfoDefaults must set the parent symbol table so that
all actors can get to the global symbols stored in AActor.
- Fixed some minor inconsistencies in the Arch-Vile's DECORATE definition.
- Fixed: A_VileAttack moved the flame without relinking it into the sector
lists. It also forgot to set the z-position correctly. (original Doom bug.)
- Fixed: The Doom 2 cast finale didn't work with the dynamic state name handling.
SVN r401 (trunk)
not even zvox.wad or the skins directory.
- Minor improvement of Hexen's Demons: They now transfer the translation
to the chunks they spawn so that they look correct if they are color
translated. See Resurrection of Chaos for an example.
- Converted Key gizmos to DECORATE.
- Converted Heretic's Beast (Weredragon) to DECORATE.
- Added a randomness parameter to A_SpawnItemEx. This allows
spawning objects with a random chance without the need to write
complicated A_Jump constructs.
- Converted Heretic's Mummy to DECORATE.
- Converted Hexen's Demons to DECORATE.
SVN r393 (trunk)
- Made the Ettin's and Centaur's howling sound an actor property.
- Added A_CustomComboAttack function to finally have something that can
replace the old A_ComboAttack function.
- Added A_SpawnItemEx function that removes the problems with A_SpawnItem
and which also should make most of the A_CustomMissile abuse unnecessary.
- Added A_QueueCorpse to the list of DECORATE code pointers.
- Made the size of Hexen's corpse queue configurable by CVAR
(sv_corpsequeuesize.) Setting this CVAR to -1 will disable corpse
queuing completely so that even in Hexen all corpses will stay forever.
SVN r392 (trunk)
- Added MissSound parameter to A_CustomMeleeAttack.
- Converted Heretic's Snake (Ophidian) to DECORATE.
- Added an option to A_CustomMissile to jump to the see state if
the caller's target is dead.
- Fixed: A_ThrowGrenade didn't play the missile's spawn sound.
- Added MF_SPAWNSOUNDSOURCE flag so that Raven's missile spawning code
pointers can be recreated with DECORATE.
- Converted a_ravenambient.cpp to DECORATE.
SVN r388 (trunk)
the build process can run uninterrupted under Vista.
- Fixed: DIRECT3DCREATE9FUNC needs WINAPI added to its prototype so that it
works properly in release build, which defaults to __fastcall.
SVN r385 (trunk)
- Made Hexenarmor factors configurable by DECORATE.
- Added support for selecting the invulnerability mode per item as well.
- Made Invulnerability and Healing radius behavior selectable by player
class instead of hard coding the special behavior to the Hexen classes.
SVN r379 (trunk)
- Added VSpeed DECORATE property so that an actor can be given an initial
vertical speed.
- Removed the barrel check in P_DamageMobj. AActor::Die is doing the same
operation unconditionally so this is redundant.
- Added A_BarrelDestroy to the list of DECORATE code pointers so that
the same effect can be recreated for other items as well.
- Renamed A_BarrelRespawn to A_Respawn, changed it so that it works for
monsters and added it to the list of DECORATE code pointers. Now Quake-style
zombies should be possible. ;)
- Changed handling of MF4_RANDOMIZE so that it applies to all actors being
spawned and not just projectiles.
- Converted Berserk and Megasphere to DECORATE.
- Fixed: HealThing should respect the stamina a player has and the Dehacked
health compatibility flag if max is 0. To do that it calls P_GiveBody now.
SVN r373 (trunk)
on the automap instead. If its first argument is zero, the map marker itself
appears on the automap, otherwise it is drawn on top of any actor with a TID
matching that argument. If the second argument is one, then the map marker
will only be appear if the player has previously seen the sector it is one.
You can use Thing_Activate and Thing_Deactivate on markers to turn them on
and off. And if you subclass MapMarker with DECORATE, you can easily make
your own custom markers.
- Fixed: Map markers could not be drawn partially off the map. They were
drawn either fully or not at all.
- Fixed: Map markers appeared in the wrong place on a rotated overlay map if
screenblocks < 10.
SVN r356 (trunk)
- If you aren't targeting x86, m_fixed.h only includes basicinlines.h now.
- Moved x64inlines.h into basicinlines.h.
- Replaced uses of __int64 with types from doomtype.h.
- The stop console command no longer ends single player games, just the demo
that was being recorded.
- In C mode, the sc_man parser no longer allows multi-line string constants
without using the \ character to preface the newline character. This makes
it much easier to diagnose errors where you forget the closing quote of a
string.
- Fixed: V_BreakLines() added the terminating '\0' to the last line of the
input string.
- Added font as a parameter to V_BreakLines and removed its keepspace
parameter, which was never passed as anything other than the default.
SVN r331 (trunk)
- The stat meters now return an FString instead of sprintfing into a fixed
output buffer.
- NOASM is now automatically defined when compiling for a non-x86 target.
- Some changes have been made to the integral types in doomtype.h:
- For consistancy with the other integral types, byte is no longer a
synonym for BYTE.
- Most uses of BOOL have been change to the standard C++ bool type. Those
that weren't were changed to INTBOOL to indicate they may contain values
other than 0 or 1 but are still used as a boolean.
- Compiler-provided types with explicit bit sizes are now used. In
particular, DWORD is no longer a long so it will work with both 64-bit
Windows and Linux.
- Since some files need to include Windows headers, uint32 is a synonym
for the non-Windows version of DWORD.
- Removed d_textur.h. The pic_t struct it defined was used nowhere, and that
was all it contained.
SVN r326 (trunk)
The lump is open anyway at that time so deferring this action until the information
is needed doesn't give any speed improvements. Now GetDimensions and all its
associated overhead is gone.
- Added support for TGA textures. It can handle all of the common variations
of this format.
- Changed: GI_PAGESARERAW is no longer checked. It wasn't really necessary before
because the chance of texture misidentification is absolutely minimal.
But raw pages are now restricted to textures of type TEX_MiscPatch only.
- Changed the automap parchment to use a regular texture. The previous
FAutomapTexture is only used as a last resort fallback now. If the code
finds a recognizable graphic it will create a proper texture for it now.
- Fixed: Flats were only auto-scaled when in Doom flat format.
- Fixed: FMultiPatchTexture::CheckForHacks blindly assumed that all patches
were FPstchTextures. Since the texture code does not have any type information
I added a new flag bIsPatch for this purpose.
- Moved all texture classes into their own source files and created a new
subdirectory 'textures' for that.
- Cleaned up the texture management code and added some stricter checks for
the validity of Doom patches. The old code liked to crash when being passed
some non-graphic data.
SVN r300 (trunk)
be a default setting.
- Moved a_artiegg.cpp to g_shared and renamed it to a_morph.cpp to better reflect
its meaning.
- Fixed: AMorphProjectile's PlayerClass and MonsterClass members must be serialized
as FNames. Serializing them as ints is not safe because name indices are not
guaranteed to be the same each time the game is started. Same for APlayerPawn's
MorphWeapon member.
- Converted EggFX, ArtiEgg, PorkFX and ArtiPork to DECORATE.
- Added a new parameter to A_FireCustomMissile. Previously it always aimed
straight ahead and altered the projectile's angle according to the resulting
direction. If the 6th parameter is 1 now it will aim at the specified angle
directly.
- Changed custom morphing to be based on a new MorphProjectile class, not
the Heretic specific EggFX. The EggFX properties are now prefixed with
'MorphProjectile.'.
SVN r297 (trunk)
down version of the library with the ZDoom source. (It actually uses less
space than zlib now.) Unix users probably ought to use the system-supplied
libjpeg instead. I modified Makefile.linux to hopefully do that. I'm sure
Jim or someone will correct me if it doesn't actually work.
SVN r293 (trunk)
probably switch to the IJG library once I pare it down. (Ken's code is 18K
of C source but does not support progressive JPEG. The IJG library is over
a megabyte of source and supports pretty much everything you would ever
need ever.)
- Fixed endianness issue in FTextureManager::CreateTexture().
- Added support for interlaced PNGs. Now ZDoom is a mostly complete PNG
reader. The only thing missing is 48-bit RGB and 16-bit grayscale support,
which are just wastes of bits here, but also less likely to appear than
an interlaced PNG. (However, if you are using interlaced PNGs for textures,
then you are needlessly wasting space, since the image won't display
progressively.)
- Fixed: Writing named screenshots didn't work.
SVN r292 (trunk)
is not available under Windows 95. Since this is (or at least should be) the
only thing preventing us from running under Windows 95, I added a stub that
replaces __imp__IsDebuggerPresent@0 with a pointer to a function that checks
for the real thing.
SVN r279 (trunk)
yanking the mouse around if they keys haven't been read yet to combat the
same situation that causes the keyboard to return DIERR_NOTACQUIRED in
KeyRead(): The window is sort of in focus and sort of not. User.dll
considers it to be focused and it's drawn as such, but another focused
window is on top of it, and DirectInput doesn't see it as focused.
- Fixed: KeyRead() should handle DIERR_NOTACQUIRED errors the same way it
handles DIERR_INPUTLOST errors. This can happen if our window had the
focus stolen away from it before we tried to acquire the keyboard in
DI_Init2(). Strangely, MouseRead_DI() already did this.
- When a stack overflow occurs, report.txt now only includes the first and
last 16KB of the stack to make it more manageable.
- Limited StreamEditBinary() to the first 64KB of the file to keep it from
taking too long on large dumps.
- And now I know why gathering crash information in the same process that
crashed can be bad: Stack overflows. You get one spare page to play with
when the stack overflows. MiniDumpWriteDump() needs more than that and
causes an access violation when it runs out of leftover stack, silently
terminating the application. Windows XP x64 offers SetThreadStackGuarantee()
to increase this, but that isn't available on anything older, including
32-bit XP. To get around this, a new thread is created to write the mini
dump when the stack overflows.
- Changed A_Burnination() to be closer to Strife's.
- Fixed: When playing back demos, DoAddBot() can be called without an
associated call to SpawnBot(). So if the bot can't spawn, botnum can
go negative, which will cause problems later in DCajunMaster::Main()
when it sees that wanted_botnum (0) is higher than botnum (-1).
- Fixed: Stopping demo recording in multiplayer games should not abruptly
drop the recorder out of the game without notifying the other players.
In fact, there's no reason why it should drop them out of multiplayer at
all.
- Fixed: Earthquakes were unreliable in multiplayer games because
P_PredictPlayer() did not preserve the player's xviewshift.
- Fixed: PlayerIsGone() needs to stop any scripts that belong to the player
who left, in addition to executing disconnect scripts.
- Fixed: APlayerPawn::AddInventory() should also check for a NULL player->mo
in case the player left but somebody still has a reference to their actor.
- Fixed: DDrawFB::PaintToWindow() should simulate proper unlocking behavior
and set Buffer to NULL.
- Improved feedback for network game initialization with the console ticker.
- Moved i_net.cpp and i_net.h out of sdl/ and win32/ and into the main source
directory. They are identical, so keeping two copies of them is bad.
- Fixed: (At least with Creative's driver's,) EAX settings are global and not
per-application. So if you play a multiplayer ZDoom game on one computer
(or even another EAX-using application), ZDoom needs to restore the
environment when it regains focus.
- Maybe fixed: (See http://forum.zdoom.org/potato.php?t=10689) Apparently,
PacketGet can receive ECONNRESET from nodes that aren't in the game. It
should be safe to just ignore these packets.
- Fixed: PlayerIsGone() should set the gone player's camera to NULL in case
the player who left was player 0. This is because if a remaining player
receives a "recoverable" error, they will become player 0. Once that happens,
they game will try to update sounds through their camera and crash in
FMODSoundRenderer::UpdateListener() because the zones array is now NULL.
G_NewInit() should also clear all the player structures.
SVN r233 (trunk)
discards the jumping bits.
- ProcessActor() now sets C mode before retrieving the actor's name.
- Fixed: The new SC_GetString() scanner accepted slashes at the end of tokens
when not in C mode, even if they were the start of a comment. Now if you
want a slash at the end, you must quote it.
SVN r211 (trunk)
while and killing centaurs with the flechette.
- Fixed: Moving to an old level in a hub caused the old player's inventory to
spawn owned by the current player (but still hanging off the old player), so
the game would hang when trying to delete it.
- Modified re2c so that it doesn't add a date to the file it generates. Thus,
if it regenerates a file during a full rebuild, SVN won't see it as a change.
Also updated it to 0.10.5.
- Fixed: SC_GetString() did not properly terminate sc_String when the last
token in the file had no white space after it. Since I could not actually
find the problem (it works fine in debug mode and I saw no logic errors),
I decided to take this opportunity to reimplement it using an re2c-generated
scanner. Now it's 1.6x faster than before and correctness is easier to
verify.
- Fixed: FMODSoundRenderer::Shutdown() also needs to reset NumChannels.
- Added back the Manifest to zdoom.rc for non-VC8 Windows compilers.
- Fixed MinGW compilation again. Now it uses the same method as Makefile.linux
to find all the source files so that it doesn't need to be manually updated
each time source files are added or removed.
- Added the SVN revision number to the version string. A new tool is used to
obtain this information from the svnversion command and write it into a
header file. If you don't have the svn command line tools installed or didn't
check it out from the repository, you can still build. I added some rules for
this to Makefile.linux, and I assume they work because they do for
Makefile.mingw.
- Fixed: MIDISong2 did not delete MusHeader in its destructor.
SVN r200 (trunk)
- Added a PickupMessage property to the internal actor parser, replaced
most of the virtual PickupMessages with it and placed the code that
reads the metadata into AInventory::PickupMessage. Now the
PickupMessage method is truly virtual and I can do:
Added a Health.LowMessage property to define double message items like
Doom's medikit in DECORATE.
- Since defining Mana3 as an ammo type and then overriding the TryPickup
method means that this item defeats all ammo checks in the game it might
as well be defined as a CustomInventory item. At least this fixes the
amount given in easy and very hard skills.
- Converted all ammo items to DECORATE.
- Changed internal property setting of ammo types and sister weapons
to use fuglyname as for DECORATE definitions. This allows to export
the ammo definitions into DECORATE definitions without doing it for
the weapons themselves.
- Replaced obituary methods with actor properties.
- Fixed: The secret map check didn't work for maps inside Zips.
SVN r196 (trunk)
or not SSE2 is available at runtime. Since most of the time is spent in
ClassifyLine, using SSE2 in just this one function helps the most.
- Nodebuilding is a little faster if we inline PointOnSide.
- Changed FEventTree into a regular binary tree, since there just aren't enough
nodes inserted into it to make a red-black tree worthwhile.
- Added more checks at the start of ClassifyLine so that it has a better chance
of avoiding the more complicated checking, and it seems to have paid off with
a reasonably modest performance boost.
- Added a "vertex map" for ZDBSP's vertex selection. (Think BLOCKMAP for
vertices instead of lines.) On large maps, this can result in a very
significant speed up. (In one particular map, ZDBSP had previously
spent 40% of its time just scanning through all the vertices in the
map. Now the time it spends finding vertices is immeasurable.) On small maps,
this won't make much of a difference, because the number of vertices to search
was so small to begin with.
