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.
As a side effect this will now allow using custom messages with this function as well by using the arg2 parameter as part of the message's name (arg2=0 will use TXT_COMM0, arg1 TXT_COMM1 and so on.)
Tags are now handled by a tag manager class which stores sector/tag pairs. This way multiple entries can be added per sector.
Since UDMF does not have any arrays the additional tags are stored as a space separated string as 'MoreIDs'.
This is done to encapsulate the gory details of tag search in one place so that the implementation of multiple tags per sector remains contained to a few isolated spots in the code.
This also moves the special 'tag == 0 -> activate backsector' handling into the iterator class.
If an actor is already targeting a goal, and Thing_SetGoal is used on
it, it would still be left targeting the old goal instead of the new
one. This messed up checks in A_Chase for walking towards a goal vs a
real target.
- 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)
Includes:
- Made the move tried from checking missile spawns ignore drop off height. This solves the Voodoo Gun ghostly civilian issue.
- Fixed: the NOTELEPORT flag is removed from Dehacked missiles which lose the MISSILE flag. This caused problems with certain special effects based on dehacked spawn cubes.
- Fixed: all Boom silent teleporters preserve relative height.
- support for palette independent particle colors if the renderer can handle them.
SVN r3329 (trunk)
- added Sector_SetTranslucent special so set translucency of portal planes at run time.
- added 'additive' information for portal planes. This is no-op at the moment because the flat drawers can't handle additive translucency yet though.
SVN r3149 (trunk)
- updated UDMF spec for player class and skill amount because the old menu limits no longer apply.
- fixed: FloorAndCeiling_LowerRaise needs to consider 4 args in maps to account for the Boom compatibility hack parameter.
