(e.g. invulnerability). This should only be necessary for SM1.4 cards with buggy drivers. I
doubt the problem is very widespread. The one piece of SM1.4 hardware I obtained specifically
for testing purposes has no problems using shaders for these effects.

each other compared to a straight tangent-to-angle calculation.
SVN r3189 (trunk)
- moved all code and data for Build tile management into FTextureManager.
- moved texture animation management into FTextureManager.
- changed: Animate textures only once per frame, not per view. Otherwise with animations that have sub-frame accuracy camera textures of the same area can show different animation frames if the frame changes falls between the rendering of the different views.

* 0. Do not clear. This is the standard behavior.
* 1. Clear to black.
* 2. Clear to white.
* 3. Alternate between black and white every 128 ms.
* 4. Step through the palette one color at a time every 32 ms.
* 5. Epileptic seizure inducing random colors every frame.

does not include xtoviewangle[centerx] in the mirroring so that the two columns at the center
of the screen do not map to the same angle. (BTW, this array is only used for the sky drawing.)
SVN r2487 (trunk)
- Added new sprite #### and frame character # to specify the behavior of sprite ---- on a
per-sprite and per-frame basis respectively.

former used fistp, which is not portable across platforms, so cannot be
used in the play simulation. They were only suitable for the renderer.
xs_Float.h also has a very fast float->fixed conversion, so FLOAT2FIXED
uses that now.
(And I also learned that the FPU's round to nearest is not the rounding I
learned in grade school but actually Banker's Rounding. I had no idea.)
(Also, also, the only thing that could have made quickertoint faster than
toint was that it stored a 32-bit int. I never timed them, and I doubt in
practice there was any real difference between the two.)
- Changed atan2f to atan2. Using floats is not a win, because the result is
returned as a double on the x87 stack, which the caller then needs to cast
down to a float using fst/fld.
SVN r1990 (trunk)
changing game code.
- made SpawningMapThing an argument of AActor::StaticSpawn instead of a global
variable.
- added a stub to the DECORATE parser for defining dynamic lights directly
in DECORATE. This is needed so that ZDoom remains compatible with any DECORATE
which uses this GZDoom feature in the future.
SVN r1935 (trunk)
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.
SVN r1860 (trunk)
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.
SVN r1858 (trunk)
closer to the original. The old code was shorter but a little slower. The
new code is a bit faster than the original with VC++ and about the same
with GCC. Interestingly, GCC produces code for Killough's version that
performs about the same as the original, but when compiled with VC++,
Killough's is notably worse.
SVN r1813 (trunk)
regardless of pain chance.
- Changed screenblocks CVAR to be settable per game.
- Added SpawnSpotForced and SpawnSpotFacingForced ACS functions.
- Added pushfactor actor property.
SVN r1638 (trunk)
- Fixed: S_ChannelEnded didn't check for a NULL SfxInfo.
- Fixed: R_InitTables did a typecast to angle_t instead of fixed_t.
- Fixed: PowerProtection and PowerDamage applied their defaults incorrectly.
- Fixed: The damage type property didn't properly read its factor.

- Cleaned up more header dependencies.

- Made the speed a parameter to A_RaiseMobj and A_SinkMobj and deleted
GetRaiseSpeed and GetSinkSpeed.

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.
SVN r1134 (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)
arbitrary point. It has been replaced with a variant that takes a polyobject
as a source, since that was the only use that couldn't be rewritten with the
other variants. This also fixes the bug that polyobject sounds were not
successfully saved and caused a crash when reloading the game. Note that
this is a significant change to how equality of sound sources is determined,
so some things may not behave quite the same as before. (Which would be a
bug, but hopefully everything still sounds the same.)
SVN r1059 (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)
were doing some things in their destructor that needed to be done in the
Destroy method.
- Rewrote the interpolation code. Interpolations are no longer some objects
that are separate from the rest of the engine. Instead, they are owned by
the thinkers starting them. Also, polyobjects only spawn a single interpolation
for each polyobject instead of a single one for each vertex.
Also, different types of interpolation objects are used for different types
of interpolation so that they can do some additional work if eventually needed.
SVN r1018 (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)
Since it uses fixed point parameters it can only be used in scripts though.
- Added flags parameters to all wall scroller specials that didn't use
all 5 args.
- Separated scrolling of the 3 different texture parts of a sidedef.
While doing this I did some more restructuring of the sidedef structure
and changed it so that all state changes to sidedefs that affect rendering
have to be made with access functions. This is not of much use to the
software renderer but it allows far easier caching of rendering data
for OpenGL because the only place I need to check is in the access functions.
SVN r832 (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)
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)
list, it should just be ignored during the propagation stage.
- After sleeping on it and realizing what was really going in, I generalized
the inventory fix from the 13th: The actor is flagged by Destroy(), then it
is later inserted into the thinker list by DThinker::SerializeAll(). So
rather than unlinking the skipped player from their inventory, just make
sure any flagged thinkers aren't inserted into a list.
- Fixed: FCanvasTextureInfo::Viewpoint needed a read barrier, and the whole
list should serve as a root.
- Reimplemented SPC playback as a custom codec for FMOD.
- Removed spc_frequency, because snes_spc only supports the SPC's native
frequency of 32000 Hz.
SVN r806 (trunk)
drawing function. The most improvement came from being able to turn some
constant variables into immediate values with self-modifying code, but I
also managed to reorder it to make it a little faster. It's about 9% faster
than VC++'s code and 19% faster than GCC's code. That's not a huge
improvement (for VC++), but at least it's measurable.
- Removed the solid fill "optimization" from rt_shaded4cols(), because in my
testing, it didn't help any and in fact, hurt just a little bit.
- In the name of simplification, all the rt_tlate* drawers were changed to do
the translation in one step and the drawing in another. This lets me call
the untranslated drawer to do the real drawing instead of mostly duplicating
them. Performance wise, there is practically no difference from before.
SVN r771 (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)
- 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)
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.
SVN r640 (trunk)
- Added a new color parameter to DCanvas::Clear() that specifies the
ARGB value of the color. This is used if the old color parameter,
which specifies a palette entry, is -1.
SVN r617 (trunk)
- Fixed: Resurrecting a player must restore all flags words, not just the first one.
- Fixed: APowerWeaponLevel2::EndEffect must check PendingWeapon for WP_NOCHANGE.
- added Skulltag's high jump rune as a powerup
- Added Skulltag's Drain and Regeneration runes as powerups and used specific player
sounds for their sound effects instead of using misc/i_pkup.
(If I ever decide to implement runes it will be in a way that can use the regular
powerups instead of having to define specific classes for them.)
- Added Skulltag's PowerQuadDamage and PowerQuarterDamage as more customizable
PowerDamage and PowerProtection. These new powerups allow free customization of
the damage modification per damage type by inheriting from these classes and
setting specific values. Such derived damage/protection powerups will be considered
as separate powers so that for example a QuadDamage and a DoubleDamage item can be
stacked which would result in 8x damage.
- merged player_t::cheats and player_t::Powers into one variable.
