- The global symbol table was never marked by the GC, so anything pointed
only by it was fair game to disappear.
- Don't clear the global symbol table during DECORATE parsing. Junk in
there should be considered constant after initialization.
- Added CF_INTERPVIEW flag for players. A_SetPitch/A_SetAngle and the
similar ACS APROPs set this when changing an angle. This forces the
renderer to interpolate the view angles instead of updating with the
latest mouse positions. The effect lasts one tick.
- Constants can be strings, but the existing PSymbolConst couldn't handle
them. The old PSymbolConst is now PSymbolConstNumeric, and the new
PSymbolConst is a now a baseclass for it and PSymbolConstString.
- If a player is spying through another player, CheckPlayerCamera will
return the TID of the player you are "spying", but as coopspy isn't a
net command, this wont be reflected by all nodes. So to fix this,
CheckPlayerCamera now returns -1 if a player's camera is that of any
player at all. (thanks edward850)
- The type systems used by PField and FxExpression are completely
incompatible, but I think I got the differences taken care of as far
as ParseNativeVariable(), ParseUserVariable(), and FxClassMember are
concerned.
- Support for declaring native bool variables has been removed for the time
being. It wasn't used anyway.
- Removed PSymbolVariable.
- Instead of changing three places to turn disassembly dumps on and off,
do it with just one place. As a side effect, this now handles the case
where the dump file can't be opened.
Since I remember that 'memset/memcpy' is safe in this code, it should be okay to cast to the generic pointer all the 'virtual class' arguments before calling the above functions. Shuts up Clang warnings.
- For the purposes of getting constant values from expressions, the only
class where Resolve doesn't duplicate the functionality of
EvalExpression was FxConstant. So, every other class has had its
EvalExpression taken away, and FxConstant has had it renamed to GetValue.
- Now that the VM supports degrees, use those instructions when emitting
code for cos and sin DECORATE expressions. (This looks like it also
fixed a bug where sqrt also did the degree to radian conversion.)
- After StateParams was removed in commit 4a1fbdb, the expressions for
default paramaters that ParseActionDef() created went nowhere and were
lost. Properly throw them away by deleting them as soon as they've been
parsed.
- Removed EvalExpression() implementations from some subclasses of
FxExpression that don't make any sense in the context of evaluating a
constant value.
- This all became vestigial code after the relevant information was all
moved into FStateTempCall. Now that the MBF code pointer code has been
converted, I can be sure it wasn't still used anywhere.
DECORATE). Then you can use:
* Bounce
* Bounce.Floor
* Bounce.Ceiling
* Bounce.Wall
* Bounce.Actor
* Bounce.Actor.Creature
Partial matches work just like Pain states, so if an actor bounces off a floor and you don't
have a Bounce.Floor state, but you do have a Bounce state, it will use the Bounce state.
Conversely, if you only have a Bounce.Floor state but no Bounce state, then the actor will
only enter the Bounce.Floor state when it bounces on a floor; bouncing off anything else will
not cause it to change state.
SVN r4250 (trunk)
When set, the actor will run this state during its first tick. This means Spawn
states may now run an action function if you set this flag. Note that this action function
is executed during the actor's first tick, which is not the same as when it is spawned.
SVN r4240 (trunk)
whatever spawned the random spawner already took care of this.
- Added a maxdist parameter to P_CheckMissileSpawn() to help ensure that it doesn't completely
move the spawned missile outside of its shooter (and potentially beyond a wall the shooter
might happen to be standing next to).
SVN r4194 (trunk)
can perform based on the amount of damage actually taken after all modifications are done to
it. However, if the damage is canceled away, blood will still spawn for the original damage
amount rather than the modified amount.
SVN r4012 (trunk)
something that never autoaims, such as a railgun.
- Fixed: A_JumpIfTargetInLOS should use P_AimLineAttack() instead of P_BulletSlope(), because the
latter intentionally checks to the sides of the aimed line.
SVN r4007 (trunk)
- Changed Actor's Damage property into an actual function. All access to the damage property
must now be done through GetMissileDamage. actor->GetMissileDamage(0, 1) is equivalent
to the former actor->Damage, for the case where actor->Damage was not an expression. (I
suppose I will probably need to make a thunk for DECORATE expressions that want to read it.)
- Cleaned up some decorate expression evaluation functions that are no longer used.
SVN r3919 (scripting)
actors with names that conflicted with preceding actors from being freed, even though they
can still be accessed via PClassActor::AllActorClasses, which gets iterated over in a number
of places. (e.g. Zen Dynamics defines a Grenade actor, although there is one in zdoom.pk3 now.
The Zen Dynamics' version would not go in the TypeTable, so it would be collected on map load,
leading to a crash when attempts to access it through AllActorClasses are made.)
SVN r3908 (scripting)
one name in its label. This avoids the alloca and security cookie calls.
- Consolidated lots of copy-pasted code in thingdef_expression.cpp to install helper functions
into FindDecorateBuiltinFunction().
SVN r3907 (scripting)
become ungodly slow when using mods with complex DECORATE. The GCC debug builds run just
fine, however. Hopefully this is something that can be fixed later with an assembly-optimized
version of the main VM loop, because I don't relish the thought of being stuck with GDB
for debugging.)
- Fixed: The ACS_Named* action specials were erroneously defined as taking strings instead of
names.
- Fixed: Copy-paste error caused FxMultiNameState::Emit to generate code that called
DecoNameToClass instead of DecoFindMultiNameState.
- Updated FxActionSpecialCall::Emit for named script specials.
- Fixed inverted asserts for FxMinusSign::Emit and FxUnaryNotBitwise::Emit.
SVN r3893 (scripting)
I could be clever and have the beggar chase after you some after you attack him, with a
random chance to cease pursuit. However, that didn't look much different from his normal
wandering animation, and he usually gave up before getting anywhere near you, so it was
kind of pointless. I kept the action functions around anyway, since they're simple things that
somebody else might find useful.
- Added a melee range check to A_SentinelRefire for actors without missile states. This fixes
Strife's Beggar trying to attack you when you're nowhere near him.
SVN r3863 (trunk)
and RTF_NOTMISSILE so that you can use A_Explode and A_RadiusThrust with non-missiles without
them telling P_RadiusAttack() that the target is the source.
SVN r3860 (trunk)
POSS A 10 A_Look
You can define it as:
POSS A random(10,20) A_Look
and the state will last a random duration between 10 and 20 tics, inclusive.
SVN r3847 (trunk)
* GruntSpeed: The minimum speed a player must be falling at the time of landing to play *grunt.
* FallingScreamSpeed: When a player is falling within this range of speeds, they will play *falling.
SVN r3829 (trunk)
function will pass its results directly to this function's caller. Eventually, this should
be changed to do a proper tail call for scripted functions.
SVN r3769 (scripting)
pickup an item at all. (For instance, normally players in Hexen can still pick up other players'
weapons for ammo. With this flag set, they cannot do that either.)
SVN r3751 (trunk)
using it in in any expression would automatically downcast it to an int unless â‘ its sibling in the expression tree was a float, or â‘¡ it was the only thing in the expression.
SVN r3721 (trunk)
overridden in custom player classes by changing their Obituary property to something else.
- ClientObituary() now only looks up the obituary message from the killing player's weapon if the
damage type was 'Melee' or 'Hitscan'.
- Gave P_GunShot() and A_FireBullets the new damage type 'Hitscan'.
- Switched A_Saw and A_CustomPunch to the 'Melee' damage type.
SVN r3646 (trunk)
- Removed A_KSpiritWeave since it was basically identical to the function CHolyWeave (besides the random number generator object) and was never exported as a native action anywhere.
SVN r3631 (trunk)
its tracer so that it will look for a new target the next time it is called.
- Extended P_RoughMonsterSearch() with a flag to indicate that it should only search for seekable
targets.
SVN r3572 (trunk)
without resetting the actor's sector. The 3D floor checks in P_NightmareRespawn() and
A_RestoreSpecialPosition now use this.
- Fixed: P_NightmareRespawn() did its Z clamping before checking for 3D floors.
- Fixed: Respawning actors were not clamped to the ceiling.
SVN r3542 (trunk)
The initial spawn did not, so this can prevent respawns of things that were initially
spawned if they happen to intersect a wall.
- Fixed: Don't respawn actors inside the floor.
- Fixed: The final calls to P_FindFloorCeiling() in P_NightmareRespawn() and A_RestoreSpecialPosition
also need to pass true as the second parameter. (Because this parameter is onlyspawnpos, not
onlymidtex.)
SVN r3518 (trunk)
same situation A_RestoreSpecialPosition, it now just calls that to do the moving. This also
means it is no longer limited to respawning things on the floor.
SVN r3514 (trunk)
for multiplayer: They now always check through the eyes of every player. For players whose
cameras are not players, they also check through the eyes of those cameras.
- Using spynext/spyprev to switch from a non-player to a player now writes a command to the
network stream and lets Net_DoCommand() take care of it later. The logic here is that if
a player is viewing from something that isn't another player, then every player needs to know
about it for sync purposes. Consequently, when they stop viewing from a non-player and switch
to a player, everybody needs to know about that too. But if they are viewing from a
player, it doesn't matter which player it is, so they can spynext/spyprev all they want
without letting the other players know about it (and without potentially breaking demos--due
to the above-mentioned two codepointers--while doing it during demo playback).
- Replaced the instances of checking players[consoleplayer].camera for a valid pointer to
ones that do it for every player.
- Fixed: Upon changing levels, all players but the consoleplayer would have their cameras NULLed.
- Fixed: player_t::FixPointers() needs to bypass the read barriers, or it won't be able to
do substitutions of old objects that are pending deletion.
SVN r3448 (trunk)
- added DECORATE properties for accuracy and stamina.
- Since these changes move properties from player_t to AActor all savegame compatibility code was removed and the min. savegame version bumped.
SVN r3427 (trunk)
named the same as their ACS function equivalents. e.g. From DECORATE, you can now use
ACS_NamedExecuteAlways to run a script with a name.
SVN r3364 (trunk)
be made to clamp other actors' pitches to within the range (-90,+90)
degrees with the SPF_FORCECLAMP flag.
- Transmit the local viewpitch limits to the other players.
SVN r3323 (trunk)
- allow setting 'Shadow' as default fuzz effect
- changed CVAR conversion that strings 'false' and 'true' get evaluated as integers 0 and 1 respectively so that changing boolean CVARs to int does not destroy their values.
SVN r3076 (trunk)
- Initialize the alt HUD explicitly in D_DoomMain.
- don't let S_UnloadReverbDef leave a broken list of sound environments behind.
- Added more code to explicitly delete data before initializing it.
SVN r3039 (trunk)
- move D_LoadWadSettings to keysections.cpp.
- made some more data reloadable.
- data structures filled by P_SetupLevel should be cleared before loading the level. They can remain non-empty in case of an error. There's probably more to fix here...
- fixed: MidiDevices and MusicAliases were not cleared before reloading local SNDINFOs.
- fixed signed/unsigned warnings in AddSwitchPair for real (GCC really allows -1u? MSVC prints a warning for that.)
SVN r3036 (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)
A_FadeTo(float target, float amount = 0.10, bool remove = false)
Alters transparency towards target by amount. If remove is true, the actor is destroyed if it reaches target.
SVN r2305 (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)
instead of PClass::m_Types (now PClass::AllClasses).
- Removed ClassIndex from PClass. It was only needed by FArchive, and maps take care of the
problem just as well.
- Moved PClass into a larger type system (which is likely to change some/lots once I try and actually use it and have a better feel for what I need from it).
SVN r2281 (scripting)
is not necessarily "self". The only visible change from this should be that inventory items
now set their own variables and not their owners'.
SVN r2235 (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)
running with the checked VM can be quite slow, since it has asserts everywhere. Some other
fixes were needed before the code actually worked:
- A_CallSpecial needs to have its arguments cast to ints.
- Some functions that set pnum/paramnum directly did not decrement it by 1. This also applies
to A_Jump, though it just uses the value of paramnum instead of changing it.
- Renamed pnum in the PARAM macros to paramnum, since pnum is already used in a few other
places for something different, so this makes searching for it easier.
This has not been tested especially thoroughly, but a first glance seems to indicate success.
SVN r2163 (scripting)
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)
only has 64 entries and is not precise enough. It now uses finesine instead.
- fixed: When compositing a multipatch texture any patch that is a multpatch
texture itself and contains rotations may not be composited directly into
the destination buffer. This must be done with an intermediate buffer.
- Fixed: Drawing a slider in the options menu did not scale the x-coordinate.
- Fixed: If the alt HUD had to draw negative numbers the minus sign was misplaced
due to incorrect texture coordinate calculations.
- changed option menu scaling for widescreen modes so that it doesn't scale down
so quickly.
- made some error messages in DECORATE that don't affect the parsing non-fatal
so that the parser can continue to find more problems.
SVN r2076 (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)
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)
unsigned integer that can use all 32 bits. They must therefore use
the unsigned mul instruction rather than the signed imul instruction.
- Fixed several signed/unsigned comparison and possibly uninitialized
variable warnings flagged by GCC.
SVN r1965 (trunk)
use a larger aiming range, and ignore non-targets in P_AimLineAttack().
- Added another parameter to P_AimLineAttack(): A target to be aimed at. If
this is non-NULL, then all actors between the shooter and the target will
be ignored.
SVN r1941 (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)
a different default terrain than a generic solid surface.
- added format char processing to A_Print(Bold) and all printable messages
that can be defined in DECORATE.
- Fixed: The railgun code ignored MF3_ALWAYSPUFF.
- added desaturated translations.
- added optional state parameters to A_ReFire and A_GunFlash and A_CountdownArg.
SVN r1921 (trunk)
can actually be used. In the end, all temporaries should be assigned to
unique virtual registers, and a register allocator can alias them to real
registers, but as long as we don't do any CSE, this is good enough for now.
SVN r1920 (scripting)
- 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)
Currently, they're only good for disassembly and pasting into a proper text editor
for viewing.
- Fixed some problems with the FxExpression emitters that were revealed by actually
using them on the standard actors.
SVN r1911 (scripting)
it isn't even used anywhere yet. In retrospect, I probably should have targeted an intermediate
representation and done codegen with that instead, since that would be something I can reuse.
SVN r1908 (scripting)
It must set it to 0 if the alpha is 0 to avoid problems with special
colormap detection.
- Changed SPECIALCOLORMAP_MASK again so that it does not interfere with
any valid setting. It must use a value with a 0-alpha because these
are guaranteed not to be produced by the DECORATE code elsewhere.
- Fixed precision issues with AddFixedColormap's search for identical colormaps.
- Added custom colormap support to texture composition code.
- Fixed initialization of FSpecialColormap::GrayscaleToColor. This is not
a mapping from the palette but from a [0,255] grayscale ramp and used to
apply colormaps to true color images for texture composition.
SVN r1867 (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)
- Derive PClass from dobject.cpp. This has one major ramification: Since the PClass
is not allocated until runtime, you cannot initialize any static/global data
structures with pointers to PClasses using RUNTIME_CLASS. Attempting to do so
will just initialize with a NULL pointer. Instead, you can initialize using
the address of the pointer returned by RUNTIME_CLASS and dereference that. By
the time you have an opportunity to dereference it, it will no longer be NULL.
- Sync CmakeLists.txt.
- Random fixes for problems GCC spotted.
SVN r1852 (scripting)
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)
- added thing activation types for BUMPSPECIAL and USESPECIAL. Also added
a new ClearSpecial flag to the activation type.
- added MBF's code for dogs jumping down, controlled by the MF6_JUMPDOWN
flag.
SVN r1835 (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)
- moved default item drop style into gameinfo.
- moved default respawn time into gameinfo.
- moved default inventory max amount into gameinfo.
- turned Heretic's blocking of the sector for LS_Plat_RaiseAndStayTx0 into
a parameter instead of having the game mode decide.
SVN r1812 (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)
max health as the mug shot max health, zero uses 100 as the mug shot max
health, and positive values used directly as the mug shot max health.
SVN r1757 (trunk)
issues that caused its inclusion. Is an optimized GCC build any faster
for being able to use strict aliasing rules? I dunno. It's still slower
than a VC++ build.
I did run into two cases where TAutoSegIterator caused intractable problems
with breaking strict aliasing rules, so I removed the templating from it,
and the caller is now responsible for casting the probe value from void *.
- Removed #include "autosegs.h" from several files that did not need it
(in particular, dobject.h when not compiling with VC++).
SVN r1743 (trunk)
missiles.) Also added PPF_NOTHRUSTWHILEINVUL to prevent invulnerable players
from being thrusted while taking damage. (Non-players were already
unthrusted.)
SVN r1695 (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)
maintains its own FOV scale independent from any other weapons the player
may have.
- Fixed: When parsing DECORATE functions that were not exported, the parser
crashed after giving you the warning.
SVN r1688 (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)
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)
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: AM_NewResolution crashed when called from outside a level.
- Added support for Quake PAK files.
- Improved warning messages for WAD files with incorrect marker usage.
SVN r1556 (trunk)
- Added -noautoload option.
- Added default Raven automap colors set. Needs to be tested because I can't
compare against the DOS version myself.
- Extened A_PlaySound and A_StopSound to be able to set all parameters of the
internal sound code.
SVN r1544 (trunk)
- Fixed: player.crouchsprite had no proper means of unsetting the crouch
sprite which is needed by the ChexPlayer.
- Fixed: A_ChangeFlags must unlink the actor from the world before changing
the NOBLOCKMAP and NOSECTOR flags.
SVN r1514 (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)
- Added FakeInventory.Respawns DECORATe property
- Fixed: Unsetting the MF5_INCONVERSATION flag did not work when quitting the
conversation by pressing Escape.
SVN r1442 (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)
vulnerability "format not a string literal and no format arguments".
- Changed the CMake script to search for fmod libraries by full name instead
of assuming a symbolic link has been placed for the latest version. It can
also find a non-installed copy of FMOD if it is placed local to the ZDoom
source tree.
SVN r1373 (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)
- Added a static error counter to FScriptPosition class.
- Changed initialization of actor class type properties: fuglyname is gone as
is the postprocessing in FinishThingdef. Instead an empty placeholder class
is now created when a class is first referenced and this placeholder is later
filled in.
- Added option to replace backslash with '^' in state frame definitions because
the backslash is just causing too many problems because it's also an escape
character.
SVN r1334 (trunk)
a player class selection menu and an episode menu.
- Fixed: AddToConsole could write outside its working buffer.
- Fixed: 0 was no longer recognized as placeholder for 'no state' in A_Chase.
- Fixed: When picking up weapons the code did not check if it should switch away
from weak weapons.
SVN r1332 (trunk)
which caused roundoff errors that made it less than 1/3 effective.
- Added support for "RRGGBB" strings to V_GetColor.
- Fixed: Desaturation maps for the TEXTURES lump were calculated incorrectly.
- Changed GetSpriteIndex to cache the last used sprite name so that the code
using this function doesn't have to do it itself.
- Moved some more code for the state parser into p_states.cpp.
- Fixed: TDeletingArray should not try to delete NULL pointers.
SVN r1312 (trunk)
failed to start the demo.
- Added a MF5_BRIGHT flag to always render an actor fullbright.
- Fixed: Calling Door_Animated with a non-zero tag created a new thinker
for each two-sided line of the sector.
- Added Karate Chris's submission for making 'spray' a cheat.
- Added CO2's default parameter additions for several Doom code pointers
submission.
- Added CO2's A_RemoveMaster/A_RemoveChildren submission.
- Added Blzut3's SBARINFO replacement for the Doom statusbar.
- Fixed: SBarInfo still displayed the wrong bar for height 0
- Added A_KillSiblings and A_DamageSiblings code pointers.
- added MaxAbsorb and MaxFullAbsorb properties for Armor.
SVN r1304 (trunk)
- Changed WI_drawPercent() when wi_percents is false so that the total
display is optional, and it formats it like Heretic's intermission, with
a slash and a fixed-width right column.
- Font is no longer a property of the screen object. Pass the font to
DrawText and DrawChar directly instead.
- Doom's intermission characters are now collected together as a font
so they can be colorized.
SVN r1294 (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)
- Fixed: The DECORATE expression evaluator was too strict with missing jump labels.
For compatibility it only may print a warning, not an error.
SVN r1284 (trunk)
structure.
- Fixed: Items which should stay but had an IF_ALWAYSPICKUP flag were removed.
- Fixed: The pickup flash must only play when an item is picked up so the
correct place to spawn it is in AInventory::Touch, not in AInventory::GoAway.
SVN r1278 (trunk)
parameters.
- All DECORATE parameters are passed as expressions now. This change allows
for compile time checks of all class names being used in DECORATE so many
incorrect definitions may output warnings now.
- Changed DECORATE sound and color parameters to use expressions.
- Changed: S_StopChannel now resets the actor's sound flags. The previous bug
made me think that delaying this until FMod calls the end of sound callback
may simply be too late.
SVN r1276 (trunk)
symbols there instead of into AActor.
- Changed the expression evaluator's floating point precision to double.
- Started rewriting the DECORATE expression evaluator to allow more flexibility.
All the operators use the new functionality but functions, variables and
constants are yet to be redone.
While doing this rewrite I noticed that random2 was always evaluated as const.
This got fixed automatically.
SVN r1264 (trunk)
* This may or may not be a problem, but GCC warned that FStateDefinitions::
AddStateDefines() does not initialize def.FStateDefine::DefineFlags, so
I fixed that.
SVN r1262 (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.
SVN r1257 (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)
- Removed extraneous printf parameter for Texman.Init startup message.
- Added newlines to the ends of a few headers that were missing them.
- Fixed more GCC errors/warnings.
SVN r1232 (trunk)
when explicitly giving them.
- Changed 'give weapon' cheat so that in single player it only gives weapons
belonging to the current game or are placed in a weapon slot to avoid
giving the Chex Quest weapons in Doom and vice versa.
- Fixed: The texture manager must be the first thing to be initialized
because MAPINFO and DECORATE both can reference textures and letting them
create their own textures is not safe.
SVN r1230 (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)
disabled for them
- Fixed: Chex Quest doesn't have a HELP2 screen so it must not be used
in the gameinfo.
- Fixed: Default blood color is no longer red so P_DrawSplash2 must
get it from the gameinfo instead.
- Added new French language texts by DoomKn1ght_.
SVN r1186 (trunk)
- Added functions to FActorInfo that can set the damage factors and
pain chances to reduce the chance of new errors when working with
these features.
- Fixed: The handling of the deprecated FIRERESIST flag didn't work.
There were 3 problems:
* Actor defaults have no class information so HandleDeprecatedFlags
needs to be passed a pointer to the ActorInfo.
* The DamageFactors list is only created when needed so the code needs to
check if it already exists.
* damage factors are stored as fixed_t but this set a float.
- Added a traditional Strife color set for the automap.
SVN r1183 (trunk)
- Fixed: The recent changes in the DECORATE parser require the special parameter
to A_CallSpecial to be an expression, not a constant.
- Removed game filters from old style decorations. No WAD in existence ever
used them and removing them allows to make the parser more robust.
SVN r1170 (trunk)
to reference its arguments directly, except 'self'. This may be helpful if it
becomes necessary to restructure this code once DoomScript becomes real.
- Removed the last remaining global variable related to action functions:
pStateCall. Everything is passed properly as function arguments now.
- fixed: PlayerChunk was missing the NOSKIN flag.
SVN r1169 (trunk)
the texture manager even if it is from Raven's IWADs.
- Removed code related to internal ActorInfo definitions from dobjtype.cpp.
- removed unneeded file dehackedactions.h
SVN r1162 (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)
- Removed AT_GAME_SET because it's no longer used anywhere.
- Converted the last remaining global classes to DECORATE.
- Fixed: Inventory.PickupFlash requires an class name as parameter not an
integer. Some Hexen definitions got it wrong.
- Converted Hexen's Pig to DECORATE.
- Replaced the ActorInfo definitions of all internal inventory classes with
DECORATE definitions.
- Added option to specify a powerup's duration in second by using a negative
number.
SVN r1137 (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)
- Fixed: AStalker::CheckMeleeRange did not perform all checks of AActor::CheckMeleeRange.
I replaced this virtual override with a new flag MF5_NOVERTICALMELEERANGE so that
this feature can also be used by other actors.
- Converted Strife's Stalker to DECORATE.
- Converted ArtiTeleport to DECORATE.
SVN r1126 (trunk)
redundant ammo multiplication code from P_DropItem and ADehackedPickup::TryPickup.
- Restricted native action function definitions to zdoom.pk3.
SVN r1123 (trunk)
occurences in the code that depended on it were changed accordingly.
Invulnerability colormaps are now being set by the items exclusively.
- Changed many checks for the friendly Minotaur to a new flag MF5_SUMMONEDMONSTER
so that it can hopefully be generalized to be usable elsewhere later.
- Added Gez's submission for converting the Minotaur to DECORATE.
SVN r1120 (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)
- Converted all of Heretic's actors except the weapons to DECORATE.
- Added the option to define the ActorInfos for native classes in DECORATE.
SVN r1078 (trunk)
treated it as a mace and wrote into some undefined memory.
- Fixed: A_BishopMissileWeave didn't initialize special2 for proper movement.
- Added a speed parameter to A_SkullAttack.
- Fixed: Black as first or only blood color didn't work.
- Fixed: Sounds played in wi_stuff.cpp and f_finale.cpp need the CHAN_UI flag.
- Fixed: Spawning a player could play the *gasp sound.
- Fixed: SBARINFO's health display didn't scale to the proper maximum.
- Added Skulltag's Teleport_NoStop action special.
SVN r1074 (trunk)
and vice versa.
- Fixed: In deathmatch specral missiles spawned by players should hurt other
players.
- Fixed: SpectralLightningBigBall didn't set the proper owner for the lightning
projectiles it spawned.
- Changed the EntityBoss's attack function to call the equivalent spectre
functions instead of duplicating their code.
- Gave many of Strife's code pointers that only had a number as name more
meaningful names.
- Fixed: All spectral attacks must set 'health' first before P_CheckMissileSpawn
is called.
SVN r1071 (trunk)
- Added a check for PUFFGETSOWNER to A_BFGSpray.
- Moved the PUFFGETSOWNER check into P_SpawnPuff and removed the limitation
to players only.
- Fixed: P_SpawnMapThing still checked FMapThing::flags for the class bits
instead of FMapThing::ClassFilter.
- Fixed: A_CustomMissile must not let P_SpawnMissile call P_CheckMissileSpawn.
It must do this itself after setting the proper owner.
- Fixed: CCMD(give) increased the total item count.
- Fixed: A_Stop didn't set the player specific variables to 0.
SVN r1066 (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)
- Fixed: The internal definition of Floor_LowerToNearest had incorrect parameter
settings.
- Fixed: Heretic's ActivatedTimeBomb had the same spawn ID as the inventory item.
- fixed: Heretic's mace did not have its spawn ID set.
SVN r1052 (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)
consideration the size and shape of the sector producing the sound. See
the lifts on Doom 2 MAP30 and compare with previous versions.
- Fixed: The stop sound for sector-based sound sequences was not played with
the CHAN_AREA flag.
- Removed the distinction between S_Sound() and S_SoundID() functions. Use
S_Sound() for both names and IDs from now on.
SVN r1034 (trunk)
mid textures linked to a moving floor.
- Fixed AActor's bouncefactor definitions which I accidentally changed when
adding wallbouncefactor.
- Fixed: A_SpawnItemEx added the floorclip offset to the z coordinate instead
of subtracting it.
SVN r1031 (trunk)
- Changed: Players don't telefrag when they are spawned now but after all
actors have been spawned to avoid accidental voodoo doll telefragging.
- Fixed: ACS scripts for non-existent maps were started on the current one.
- Added a 'wallbouncefactor' property to AActor.
- Reverted forceunderwater change from r1026 and fixed the problem for real:
SECF_FORCEDUNDERWATER only has meaning when coming from the heightsec.
So the initial check of the current sector in AActor::UpdateWaterLevel
must only check for SECF_UNDERWATER, not SECF_UNDERWATERMASK.
SVN r1027 (trunk)
capturing the mouse.
- Changed: Telefragging should not thrust the victim if it isn't in precisely the
same position as the killer.
- fixed: A_SpawnItemEx must call P_TeleportMove before checking the spawned
object's position.
SVN r1014 (trunk)
(actors being forced to the ground by instantly moving sectors, strife
railing handling and shooting lines with a non-zero but unassigned tag.)
With UDMF such semantics have to be handled diffently.
- finalized UDMF 1.0 implementation.
- Added Martin Howe's latest morph update.
SVN r987 (trunk)
definitions in HIRESTEX. The feature should be complete now.
- Fixed: A_CheckTargetInLOS used BAM angles instead of degrees which is the
DECORATE convention.
- Added Snowkate709's A_CheckTargetInLOS addition.
- Added listmaps CCMD.
SVN r974 (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)
- Separated mapthing2_t into mapthinghexen_t and the internal FMapThing so
that it is easier to add new features in the UDMF map format.
- Added some initial code to read UDMF maps.
SVN r956 (trunk)
- Also changed all true color texture creation functions to use proper alpha
values instead of inverted ones.
- Changed FRemapTable so that all palette entries must contain proper alpha
values.
- Fixed: The F1 screen check in m_menu.cpp was missing a NULL pointer check.
- Changed: The boss brain's explosions play weapons/rocklx which is an
unlimited sound. This can become extremely loud. Replaced with a new
sound which is just an alias to weapons/rocklx but has a limit of 4.
SVN r932 (trunk)
- Added support for defining composite textures in HIRESTEX. It is not fully tested
and right now can't do much more than the old TEXTUREx method.
- Added a few NULL pointer checks to the texture code.
- Made duplicate class names in DECORATE non-fatal. There is really no stability
concern here and the worst that can happen is that the wrong actor is spawned.
This was a constant hassle when testing with WADs that contain duplicate resources.
SVN r905 (trunk)
to enable Timidity to read its config from Zips.
I put this on hold though after finding out that the sound quality
isn't even near that of Timidity++.
- GCC-Fixes (FString::GetChars() for Printf calls)
- Added a dummy Weapon.NOLMS flag so that Skulltag weapons using this flag
can be loaded
SVN r901 (trunk)
Chaos Device. This sound is not defined by the other games so it won't
play by default.
- Added MORPH_UNDOBYTOMEOFPOWER and MORPH_UNDOBYCHAOSDEVICE flags
for the morph style so that the special behavior of these two items
can be switched on and off.
SVN r890 (trunk)
