The reason for defining them is to be able to fill out the Eternity translation table for GZDoom's Extradata parser.
Most of the new specials are mere specializations of ZDoom's Generic_* functions and occupy positions above 255 to avoid filling up the last remaining free slots available for Hexen format maps.
Allowing action specials greater than 255 required a few changes:
* all access to action specials is now through a small set of access functions.
* Two new PCodes were added to ACC to handle these new specials from scripts.
* a minor change to the network protocol, so netgame and demo version numbers were bumped.
* FS_Execute is now properly defined in p_lnspec.cpp.
Two of the newly added specials - generalizations of the special 'close Door in 30 seconds' and 'raise door in 5 minutes' sector types, will also be available to Hexen format maps. The rest are limited to use in ACS, UDMF and DECORATE.
This also adds 'change' and 'crush' parameters to most Floor_* and Ceiling_* specials, again to match Eternity's feature set.
- moved sector secret information from sector_t::special and secretsector to two flag bits in sector_t::Flags.
This is to get rid of the bit masking madness in the floor/ceiling thinkers which need to preserve this bit when they change a sector's type.
(i.e. ACS_Execute, etc.), set the arg0str property to the name of the script to execute. The
standard numeric arg0 property will be ignored in this case.
SVN r3372 (trunk)
- Added ACS_Named* function variants of the ACS_* specials that take script names instead of
numbers. As these are functions and not specials, they can only be used from inside ACS.
SVN r3363 (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)
unused line argument fields, because these maps could potentially break
in the future if the argument is later assigned a meaning. (Hopefully
all the argument counts in actionspecials.h are accurate. I found a
few that were wrong.)
SVN r1817 (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)
like doors. This flag is on by default for any monster which was the
previous behavior.
- Optimized the DECORATE flag parser so it can more efficiently handle
the deprecated flags. As a side effect of this optimization the deprecated
flags became usable in A_ChangeFlag again.
- Changed LONGMELEERANGE flag into a MeleeThreshold property.
- Changed SHORTMISSILERANGE flag into a MaxTargetRange property.
- Added Thing_Stop action special.
SVN r517 (trunk)
with an FString now.
- Fixed: The music strings in the default level info were never freed and
caused memory leaks when used repeatedly.
- Fixed: The intermusic string in the level info was never freed.
- Fixed: The default fire obituary should only be printed if the damage
came from the environment. If it comes from a monster the monster specific
obituary should be used instead.
- Added custom damage types from the floating point test release.
- Changed Pain Elemental's massacre check. Now A_PainDie checks for the damage
type and doesn't spawn anything if it is NAME_Massacre. A_PainDie can also
be used by other actors so a more generalized approach is needed than hard
coding it into the Pain Elemental.
- Converted a few of Doom's monsters to DECORATE because I couldn't test the
first version of the custom state code with the corpses inheriting from them.
- Added custom states from last year's floating point test release and fixed
some bugs I found in that code. Unfortunately it wasn't all salvageable
and it was easier to recreate some parts from scratch.
SVN r368 (trunk)
bWorldPanning flag. Also added some NULL pointer checks to the
hires texture loading code.
- Added Sector_SetFloorScale2 and Sector_SetCeilingScale2 line specials.
They are mostly the same as Sector_Set*Scale but take fixed point parameters.
This makes them easier to use and more precise than the old ones which
offered very small fractional precision.
- Changed Thing_Deactivate so that passing a tid of 0 deactivates the calling
actor.
- Added MeansOfDeath parameter to DamageThing.
SVN r350 (trunk)
dialogs.
- Added Thing_Raise special that allows Arch-Vile like resurrections from scripts
or DECORATE states.
- Added a RadiusDamageFactor property for actors. This replaces the hard coded
factor of 0.25 for Hexen's players.
- Added new SpawnProjectile function to ACS. It's the same as Thing_Projectile2
but the projectile is specified by name, not spawn ID.
- Added MAPINFO option to set the compatibility flags. If this is done these
explicit settings will take precedence over the compatflags CVAR.
SVN r164 (trunk)
- Converted a_zombie.cpp and most of a_strifestuff.cpp to DECORATE.
- Converted a_strifekeys.cpp to DECORATE and moved the pickup messages to the
string table.
- Removed the WIF_HITS_GHOSTS weapon flag and replaced it with MF2_THRUGHOST.
There is no need to keep two flags around with virtually the same meaning.
- Changed the ShadowArmor to use the VISIBILITYPULSE flag to change its translucency.
It looks much better now than the cheap code pointer based blinking it used before.
- Converted most of a_strifeitems.cpp to DECORATE and moved the pickup messages
to the string table.
- Converted a_strifearmor.cpp to DECORATE and moved the pickup messages to the
string table.
- Moved the messages for killing spectres to the string table.
- Converted the quest items to DECORATE. Also changed A_GiveQuestItem to get
the messages it prints from the string table instead of the quest item's tag
string.
May 5, 2006 (Changes by Graf Zahl)
- Removed the hopelessly outdated thingdef_doc.txt file from the repository.
- Converted a_peasant.cpp and a_ratbuddy.cpp to DECORATE.
- Fixed: C_DoKey didn't treat an empty string as 'no binding' when checking for
valid double bindings.
- Converted a_merchants.cpp to DECORATE.
- Added MF5_NODAMAGE flag to generalize the behavior of Strife's merchants which
can be shot but take no damage from getting hurt.
- Converted a_beggars.cpp to DECORATE.
- Added an Inventory.GiveQuest property. This makes it possible to define all of
Strife's original items that also give a quest item in DECORATE but it is also
useful to define items like the ones in Day of the Acolyte without ugly workarounds.
- Added a Tag property and Strife teaser conversation IDs to DECORATE so now it is
possible to define many of Strife's items.
- Added a FastSpeed property to DECORATE so that projectiles can finally be
assigned a higher speed for fast mode.
- Added a ACS_LockedExecuteDoor special. It is basically the same as the existing
ACS_LockedExecute but it uses the 'door' message instead of 'remote'. This
cannot be integrated into ACS_LockedExecute because all its arguments are already
in use.
- Added a fully customizable A_CustomMeleeAttack function for DECORATE.
