* savegames stored an index in the switch table and performed no validation when loading a savegame.
* setting of a random switch animation duration was broken.
* separated the 2 values stored in the Time variable into 2 separate variables.
* defining a switch with one texture already belonging to another switch could leave broken definitions in the switch table.
- added function for serializing switch and door animation pointers.
- bumped min. savegame versions due to changes to DButtonThinker and removed all current savegame compatibility code.

* When you jump, it gets set to 18.
* When you land, it gets set to 7.
* As long as it is non-zero, it counts down, and you cannot jump.
Of note here, is that setting it to 18 upon jumping seems useless, since you can't jump unless
you're on the ground, and when you reach the ground, it will always be set to 7. With that in
mind, the new behavior is:
* When you jump, it gets set to -1.
* When you land, if it is less than zero or you fall far enough to squat, jumpTics will
be set to 7. Otherwise, jumpTics is left alone.
* If jumpTics is positive, it will count down each tic.
* As long as JumpTics is non-zero, you cannot jump.
SVN r2970 (trunk)
* the sprite used for 'pause'.
* the factor with which a monster's health is multiplied to decide if it's supposed to be gibbed,
* the decision to make monsters run faster in nightmare mode.
- moved the hard coded lock messages for lock types 102 and 103 into the language lump.
- fixed: Raven's fast monsters could become slower in Nightmare if they had very short walking states.
SVN r2834 (trunk)
- merged all places where secrets are credited into one common function.
- added the Doom64 COUNTSECRET actor flag.
- fixed: AInventory::CreateCopy did not clear the COUNTITEM flag.
- fixed: Dropping an item did not increase the item count but the dropped item could still have the COUNTITEM flag. Now this flag gets cleared when the item gets picked up so that dropped items don't count a second time.
SVN r2826 (trunk)
- add a GetReplacement method to PClass to clean up some really ugly code
- Who wrote the 'kill' CCMD? The way it checked if two classes were identical was horrendously overcomplicated.
SVN r2601 (trunk)
- fixed: All blood spawning functions checked the ALLOWPARTICLES flag on the class defaults before actor replacement instead of after.
SVN r2563 (trunk)
- fixed: AActor::CanSeek had the check for the visibility of the target actor's alpha reversed.
- added an Alt HUD icon for Hexen's fighter's fist.
SVN r2501 (trunk)
- Added new sprite #### and frame character # to specify the behavior of sprite ---- on a
per-sprite and per-frame basis respectively.
SVN r2291 (trunk)
- fixed memory leaks in SBARINFO and WAD loading code.
- added GetBloodColor and GetBloodType inline functions to AActor to wrap the GetMeta calls used for this.
SVN r2234 (trunk)
Reinstated Doom's original code that made projectiles with the MF_NOCLIP flag set continue to exist even
though the movement itself was never properly handled.
Fortunately the game mode check formerly associated with this can be removed because none of the other games have
any projectiles using MF_NOCLIP so at least it's no longer restricted to Doom...
SVN r2187 (trunk)
This is compatibility optioned with COMPAT_STAIRINDEX. Also added a compatibility setting for
Eternal Doom MAP25 which relies on Doom's original broken behavior.
- added a few sanity checks for duplicate actor names in DECORATE. ZDoom will now print more warnings
and all crash cases should be properly handled but since this is still an error this will not work
properly in all circumstances. For example, if you have a duplicate name all classes that inherit
from the original definition will not survive a savegame if they reference a state belonging to that
class at the point of saving.
- Print 'tried to register class more than once' in red to highlight it.
- fixed: actors may not replace themselves.
SVN r2158 (trunk)
they are both created by the first-stage Sigil. AlienSpectre3 should have also been
immune to them but was not. In addition, Macil1 was erroneously immune to V1, when he should
not be immune to any spectral damage. (Though, since he's immortal, all that really amounts to
is that he can enter his pain state.)
SVN r2106 (trunk)
because it exposed a design flaw in the thinker system:
Having every single actor default to the highest available statnum means that
nothing can be placed in a slot where it is guaranteed to be run after all actors
have ticked. But this is required for any thinker that moves an actor
(i.e. AActorMover and DSectorEffect.) With DSectorEffect it just went unnoticed
because they were added at the end of the list so almost nothing they moved was
behind them in a thinker list. However, when an actor was spawned on a moving
floor it did not move smoothly. The default statnum is now 100 so that there's
sufficient slots above where such thinkers can be placed.
SVN r2060 (trunk)
it happened outside the moved actor's Tick function. This got particularly
obvious with moving skybox viewpoints (See Daedalus's MAP21 intro for a good
example.)
SVN r2059 (trunk)
player does not immediately activate switches. oldbuttons was not usable
for this. This also required that CopyPlayer preserves this info.
- Fixed: When restarting the music there was a NULL pointer check missing
so it crashed when the game was started wi
- Fixed: If the Use key is used to respawn the player it must be cleared
so that it doesn't trigger any subsequent actions after respawning.
- Fixed: Resurrecting a monster did not restore flags5 and flags6.
- Fixed: Projectiles which killed a non-monster were unable to determine
what precisely they hit because MF_CORPSE is only valid for monsters.
A new flag, MF6_KILLED that gets set for all objects that die, was added
for this case.
- Added a generic A_Weave function that exposes all possible options of
A_BishopMissileWeave and A_CStaffMissileSlither. These 2 functions are
no longer needed from DECORATE and therefore deprecated.
SVN r2045 (trunk)
But that's insufficient because it doesn't factor in any subsequent velocity
change that happens between the damaging and the next call to A_FreezeDeathChunks.
- fixed: The TimeFreezer did not freeze other players' controls in a
multiplayer game.
- fixed: DECORATE's 'gravity' property incorrectly messed around with the
NOGRAVITY flag.
- fixed: Hitscan attacks didn't check the puff's replacement for damage types.
SVN r2026 (trunk)
The editor number for player start spot 5 is now stored in the game info
so that there's only one place where this check needs to be done.
- Fixed: WIF_NOAUTOAIM only worked for projectiles unlike Skulltag's original
implementation.
SVN r1997 (trunk)
* when a logical condition was rewritten and inverted, one of the boolean test wasn't inverted along the rest. So the "monster must not be a player" was accidentally changed into "monster must be a player", which is usually going to be false... There's another minor, but related issue.
SVN r1948 (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)
A_SetUserVar/SetUserVariable/GetUserVariable now take a variable name
instead of an array index. A_SetUserArray/SetUserArray/GetUserArray
have been added to access elements in user-defined arrays.
SVN r1933 (trunk)
but should use the camera position instead to get the correct position for
the closest point along the trail.
- Fixed: Explosions no longer caused splashes.
- Fixed: Copying translations to lower decals had the shade color check wrong.
- Fixed: Waggling floors did not move attached geometry.
- Cleaned up p_floor.cpp so that related parts of the code are grouped together.
SVN r1926 (trunk)
- fixed: When a blasted actor collided with another one this other actor's
DONTBLAST flag was not checked.
- added a global DamageFactor actor property. All damage this actor takes is multiplied
by this factor in addition to damage type specific damage factors.
SVN r1915 (trunk)
- fixed: The BossCube could be blocked by floors and ceiling resulting
in incorrect movement. I changed it so that A_BrainSpit now sets the
MF5_NOINTERACTION flag for anything it spawns that has the MF_NOCLIP
flag. For travelling cubes active collision detection makes no sense
and only causes problems. This should also make the boss brain
work in the other games which previously were excluded by a game mode
check in the movement code.
- fixed: ACS's GetUserVariable did not work for the script activator.
- fixed: Moving floors could be blocked by 2 actors without MF2_PASSMOBJ
overlapping each other (common mapping bug, check Herian 2 MAP30.)
SVN r1891 (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)
BOUNCE_MBF and BOUNCE_UseSeeSound, too, when clearing one of these flags.
- Fixed: When adding the AVOIDMELEE code the code was accidentally changed so that
friendly monsters could no longer acquire targets by themselves.
- Renamed WIF_BOT_MELEE to WIF_MELEEWEAPON because it's no longer a bot only flag.
- Added MBF's monster_backing feature as an actor flag: AVOIDMELEE.
SVN r1848 (trunk)
* MBF's dog (definition only, no sprites yet.)
* User variables. There's an array of 10. They can be set and checked in both DECORATE and ACS.
* Made the tag name changeable but eliminated the redundancy of having both the meta property and the individual actor's one. Having one is fully sufficient. TO BE FIXED: Names are case insensitive but this should better be case sensitive. Unfortunately there's currently nothing better than FName to store a string inside an actor without severely complicating matters. Also bumped savegame version to avoid problems with this change.
SVN r1823 (trunk)
- Added more things from Gez's experimental build:
* MBF grenade and bouncing code.
* Arch Vile ghosts emulation (only for compatibility.txt.)
* Several MBF related compatibility options.
SVN r1821 (trunk)
* info CCMD to print extended actor information (not fully implemented yet)
* summonmbf CCMD.
* Beta BFG code pointer (but not the related missiles yet.)
* PowerInvisibility enhancements.
* ScoreItem with one significant change: Added a score variable that can be
checked through ACS and DECORATE. The engine itself will do nothing with it.
* Nailgun option for A_Explode.
* A_PrintBold and A_Log.
* A_SetSpecial.
SVN r1819 (trunk)
- fixed: Floor and ceiling hugger projectiles should not be spawned with ONFLOORZ or ONCEILINGZ
because that will make them ignore the actual floor height if it differs from the sector's floor.
- fixed: Floor and ceiling huggers spawned by a player did not get their vertical velocity set to 0.
- some sidenum related changes in inactive 3D floor code.
SVN r1802 (trunk)
the various bounce-related flags spread across the different Actor flags
field into a single BounceFlags field.
- Fixed: P_BounceWall() should calculate the XY velocity using a real
square root and not P_AproxDistance(), because the latter can cause
them to speed up or slow down.
SVN r1796 (trunk)
that were changed some time ago.
- fixed: The damage inflictor for a rail attack was the shooter, not the puff.
- Fixed: Floor and ceiling huggers may not change their z-velocity when seeking.
- Fixed: UDMF set the secret sector flag before parsing the sector's properties,
resulting in it always being false.
- Renamed sector's oldspecial variable to secretsector to better reflect its
only use.
- Fixed: A_BrainSpit stored as the SpawnShot's target the intended BossTarget,
not itself contrarily to other projectile spawning functions.
A_SpawnFly then used the target for CopyFriendliness, thinking it'll be the
BossEye when in fact it wasn't.
- Added Gez's submission for a DEHACKED hack introduced by Boom.
(using code pointers of the form 'Pointer 0 (x statenumber)'.
- fixed: Attaching 3DMidtex lines by sector tag did not work because lines
were marked by index in the sector's line list but needed to be marked by
line index in the global array.
- fixed: On Linux ZDoom was creating a directory called "~.zdoom" for
save files because of a missing slash.
- fixed: UDMF was unable to read floating point values in exponential format
because the C Mode scanner was missing a definition for them.
- fixed: The recent changes for removing pointer aliasing got the end sequence
info from an incorrect variable. To make this more robust the sequence index
is now stored as a hexadecimal string to avoid storing binary data in a string.
Also moved end sequence lookup from f_finale.cpp to the calling code so that
the proper end sequences can be retrieved for secret exits, too.
SVN r1777 (trunk)
- Fixed: Even though P_DamageMobj checked an attack's originator
for MF2_NODMGTHRUST the same check was missing from P_RadiusAttack.
- Fixed: A_MinotaurRoam should not assume without check that it was
called by a MinotaurFriend.
- Fixed: The Minotaur declared A_MntrFloorFire which it did not use.
- Fixed: All Spawnspot functions did not check for a spot tid of 0 as
the script's activator.
- Fixed: Friendly monsters ignored team association of their owning
players.
SVN r1770 (trunk)
1000 as the threshold for god mode damage to use it instead. (Players with
MF2_INVULNERABLE set already used 1000000 as their threshold.)
SVN r1755 (trunk)
- Fixed: TObjPtr did not use a union to map its 2 pointers together.
- Added a compatibility mode for A_Mushroom. For DECORATE it is an additional
parameter but to force it for Dehacked mods some minor hacks using the
Misc1 variable were needed.
SVN r1746 (trunk)
velocity, and now it's known as such. The actor variables momx/momy/momz
are now known as velx/vely/velz, and the ACS functions GetActorMomX/Y/Z
are now known as GetActorVelX/Y/Z. For compatibility, momx/momy/momz will
continue to work as aliases from DECORATE. The ACS functions, however,
require you to use the new name, since they never saw an official release
yet.
SVN r1689 (trunk)
a Minotaur couldn't spawn floor flames when standing in water having its
feet clipped.
- added vid_vsync to display options.
- fixed: Animations of type 'Range' must be disabled if the textures don't
come from the same definition unit (i.e both containing file and use type
are identical.)
- changed: Item pushing is now only done once per P_XYMovement call.
- Increased the push factor of Heretic's pod to 0.5 so that its behavior
more closely matches the original which depended on several bugs in the engine.
- Removed damage thrust clamping in P_DamageMobj and changed the thrust calculation
to use floats to prevent overflows. The prevention of the overflows was the
only reason the clamping was done.
- Added Raven's dagger-like vector sprite for the player to the automap code.
SVN r1668 (trunk)
* BUMPSPECIAL flag: actors with this flag will run their special if collided on by a player
* WEAPON.NOAUTOAIM flag, though it is restricted to attacks that spawn a missile (it will not affect autoaim settings for a hitscan or railgun, and that's deliberate)
* A_FireSTGrenade codepointer, extended to be parameterizable
* The grenade (as the default actor for A_FireSTGrenade)
* Protective armors à la RedArmor: they work with a DamageFactor; for example to recreate the RedArmor from Skulltag, copy its code from skulltag.pk3 but remove the "native" keyword and add DamageFactor "Fire" 0.1 to its properties.
SVN r1661 (trunk)
- Added MF6_NOFEAR flag.
- Added A_MonsterRefire(probability, jumptarget).
- Added A_JumpIfTargetInSight(state) action function.
- Changed: Puffs set their angle to face the originator of the attack.
- Strife's burning hands originally make the level view fullbright.
changed in ZDoom to do partial brightening.
SVN r1642 (trunk)
the game has finished.
- Added NOBOSSRIP flag. Note: we are now at flags6!
- Added SetSkyScrollSpeed(int skyplane, fixed speed) ACS function.
- Added THRUACTORS flag that disables all actor<->actor collision detection.
- Added DONTSEEKINVISIBLE flag for missiles that can't home in on invisible
targets.
- Added SFX_TRANSFERPITCH flag to A_SpawnItemEx.
- Added Ultimate Freedoom IWAD detection.
- Added GetAirSupply and SetAirSupply functions to ACS.
- Fixed: The *surface sound was not played when drowning was switched off
by setting the level's air supply to 0.
SVN r1619 (trunk)
- Changed bounce flags into a property and added real bouncing sound properties.
Compatibility modes to preserve use of the SeeSound are present and the old
flags map to these.
SVN r1599 (trunk)
- 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.
SVN r1583 (trunk)
- Fixed: P_CheckSwitchRange tried to access a line's backsector without
checking if it is valid.
- Fixed: Fast projectile could not be frozen by the Time freezer.
- Added several new ACS functions: GetActorMomX/Y/Z, GetActorViewHeight,
SetActivator, SetActivatorToTarget.
SVN r1578 (trunk)
- Fixed: Gravity application was not correct. For actors with no vertical
momentum the initial pull is supposed to be twice as strong as when
vertical movement already takes place.
- added invquery CCMD like in Strife. Also removed all underscores from the
tag strings so that they can be printed properly.
- Fixed: Skill baby was missing 'autousehealth' for all games.
- Added a new CVAR: sv_disableautohealth
- Autouse of health items is no longer hardwired to the default item classes.
There's a new property HealthPickup.Autouse. 0 means no autouse, 1 a small
Raven health item, 2 a large Raven health item and 3 a Strife item.
SVN r1452 (trunk)
- changed weapon slots to be stored per player. Information is now transmitted
across the network so that all machines know each player's current weapon
configuration so that it can be used by cheats or HUD display routines.
SVN r1430 (trunk)
have those escapes stripped before printing so that they do not merge with
subsequent text.
- Moved default weapon slot assignments into the player classes.
Weapon.SlotNumber is now used solely for mods that want to add new weapons
without completely redoing the player's arsenal. Restored some config-based
weapon slot customization, though slots are no longer automatically saved
to the config and section names have changed slightly. However, unlike
before, config slots are now the definitive word on slot assignments and
cannot be overridden by any other files loaded.
- Fixed: Several weapons were missing a game filter from their definitions.
- Removed storage of weapon slots in the config so that weapon slots can
be setup in the weapons themselves. Slots are still configurable, since
they need to be for KEYCONF to work; any changes simply won't be saved
when you quit.
- Removed limit on weapon slot sizes.
SVN r1428 (trunk)
certain actors and added an option to APowerInvisibility to set this
flag when active.
- Added map specific automap backgrounds.
- Fixed: Voodoo dolls did not play a sound when dying.
- Added colorized error messages to DECORATE and made a few more error
conditions that do not block further parsing not immediately abort.
- Made all errors in CreateNewActor not immediately fatal so that the
rest of the DECORATE lump can be parsed normally to look for more errors.
- Fixed: Defining classes with the same name as their immediate base class
was legal. It should not be allowed that a class has another one with the
same name in its ancestry.
- Fixed: Formatting of the intermission screen on Heretic, Hexen and Strife
was broken. Changed it to use WI_Drawpercent which does it properly and
also allows showing percentage in these games now.
- Fixed: The MAPINFO parser ignored missing terminating braces of the last
block in the file.
SVN r1425 (trunk)
change levels while dead by immediately respawning you before the switch
so that you get to keep all your inventory.
- Fixed: G_InitLevelLocals() did not set flags2.
SVN r1406 (trunk)
- fixed: The nextmap and nextsecret CCMDs need to call G_DeferedInitNew instead of G_InitNew.
- merged MAPINFO branch back into trunk.
SVN r1393 (trunk)
- added a new compatmode CVAR which allows setting some generic compatibility
flag combinations:
Doom: sets the options needed to make most Doom.exe compatible map play without
errors.
Doom (strict): Same as above but sets a few more options. Please note that this
does not mean full Doom.exe behavior emulation.
Boom: Sets all options that consider differences between ZDoom and Boom.
ZDoom 2.0.63: Sets only the COMPATF_SOUNDTARGET option which is needed for
many older ZDoom maps.
- added new COMPAT_CROSSDROPOFF option to block monsters from being pushed over
dropoffs by damage kickback.
- fixed: AFastProjectile::Tick must call Effect only 8 times per tic, regardless
of the amount of steps taken.
- fixed: momentum checks in AFastProjectile did not use absolute values.
SVN r1369 (trunk)
clone a texture. Used for creating warping textures.
- Fixed: P_FindFloorCeiling should not be called before setting the actor's z-
coordinate. For testing 3D Midtex lines and 3D floors the proper position
needs to be set first.
- Fixed the autoaim fix from Jan 10.
SVN r1358 (trunk)
delayed until after its z-coordinate has been set. That means that for
map spawns AActor::StaticSpawn may not call P_FindFloorCeiling for such
actors.
SVN r1352 (trunk)
- Fixed: P_RailAttack used the shooting actor or a default puff for some splash
related actions. It should use the puff type passed to it as a parameter instead.
- Changed splash handling in P_LineAttack to use the actual hit position to
spawn the splash and not the puff's spawn position which is offset a little.
- made some precision related changes to P_HitWater. The precise hit coordinate
can now be passed as parameters.
SVN r1350 (trunk)
the time freezer and make them behave better.
- Fixed: When sounds are paused not all newly started sounds should actually
be played.
- Fixed: SBARINFO had no means to check if a weapon uses any ammo at all and
as a result the inventory icon was misplaced if a no-ammo weapon was selected.
SVN r1343 (trunk)
in such a sector. As a workaround for current map formats a new actor
(DoomEdNum 9041) was added that can set the extended sector flags without the
use of ACS and sector tags. The new flag can also be set with Sector_ChangeFlags.
- Fixed: Players ignored MF2_TELESTOMP and always telefragged what was in the way.
- Fixed: Actors with MF5_NOINTERACTION were not affected by the time freezer.
SVN r1315 (trunk)
- Added kill count awareness to A_ChangeFlag.
- P_NightmareRespawn() now clears the MTF_AMBUSH flag, so respawned monsters
aren't dormant (since there would be no way to activate them, and they
were certainly not dormant when they died).
SVN r1287 (trunk)
against decorations without breaking anything newer:
Added a new 'projectilepassheight' property that defines an alternative height
that is only used when checking a projectile's movement against this actor.
If the value is positive it is used regardless of other settings, if it is
negative, its absolute will be used if a new compatibility option is enabled
and if it is 0 the normal height will be used.
SVN r1253 (trunk)
the NextState parameter is. The code did some rather unsafe checks with it
to determine its type.
- moved all state related code into a new file: p_states.cpp.
- merged all FindState functions. All the different variations are now inlined
and call the same function to do the real work.
SVN r1243 (trunk)
some changes to the MAPINFO parser which tried to access the texture manager
to check if the level name patches exist. That check had to be moved to
where the intermission screen is set up.
- Fixed: 'bloodcolor' ignored the first parameter value when given a list
of integers.
Please note that this creates an incompatibility between old and new
versions so if you want to create something that works with both 2.2.0
and current versions better use the string format version for the color
parameter!
- Rewrote the DECORATE property parser so that the parser is completely
separated from the property handlers. This should allow reuse of all
the handler code for a new format if Doomscript requires one.
- Fixed: PClass::InitializeActorInfo copied too many bytes if a subclass's
defaults were larger than the parent's.
- Moved A_ChangeFlag to thingdef_codeptr.cpp.
- Moved translation related code from thingdef_properties.cpp to r_translate.cpp
and rewrote the translation parser to use FScanner instead of strtol.
- replaced DECORATE's 'alpha default' by 'defaultalpha' for consistency.
Since this was never used outside zdoom.pk3 it's not critical.
- Removed support for game specific pickup messages because the only thing
this was ever used for - Raven's invulnerability item - has already been
split up into a Heretic and Hexen version.
SVN r1240 (trunk)
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.
SVN r1226 (trunk)
automatically used by all inventory classes.
- The previous change made it necessary to replace all TryPickup calls with
another function that just calls TryPickup.
- Fixed: AInventory::TryPickup can change the toucher so this must be reported
to subclasses calling the super function. Changed TryPickup to pass the
toucher pointer by reference.
SVN r1221 (trunk)
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.
SVN r1146 (trunk)
- Made the speed a parameter to A_RaiseMobj and A_SinkMobj and deleted
GetRaiseSpeed and GetSinkSpeed.
- Added some remaining DECORATE conversions for Hexen by Karate Chris.
SVN r1144 (trunk)
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)
- AActor::PreExplode is gone now that the last item that was using it has been converted.
- Converted the Sigil and the remaining things in a_strifeitems.cpp to DECORATE.
SVN r1132 (trunk)
