Needless to say, this is simply too volatile and would require constant active maintenance, not to mention a huge amount of work up front to get going.
It also hid a nasty problem with the Destroy method. Due to the way the garbage collector works, Destroy cannot be exposed to scripts as-is. It may be called from scripts but it may not be overridden from scripts because the garbage collector can call this function after all data needed for calling a scripted override has already been destroyed because if that data is also being collected there is no guarantee that proper order of destruction is observed. So for now Destroy is just a normal native method to scripted classes
- instead add a list of SpecialInits to VMScriptFunction so this can be done transparently when setting up and popping the stack frame. The only drawback is that this requires permanent allocation of stack objects for the entire lifetime of a function but this is a relatively small tradeoff for significantly reduced maintenance work throughout.
- removed most #include "vm.h", because nearly all files already pull this in through dobject.h.
* everything related to scripting is now placed in a subdirectory 'scripting', which itself is separated into DECORATE, ZSCRIPT, the VM and code generation.
* a few items have been moved to different headers so that the DECORATE parser definitions can mostly be kept local. The only exception at the moment is the flags interface on which 3 source files depend.
- The A_Jump family of action functions now return the state to jump
to (NULL if no jump is to be taken) instead of jumping directly.
It is the caller's responsibility to handle the jump. This will
make it possible to use their results in if statements and
do something other than jump.
- DECORATE return statements can now return the result of a function
(but not any random expression--it must be a function call). To
make a jump happen from inside a multi-action block, you must
return the value of an A_Jump function. e.g.:
{ return A_Jump(128, "SomeState"); }
- The VMFunction class now contains its prototype instead of storing
it at a higher level in PFunction. This is so that
FState::CallAction can easily tell if a function returns a state.
- Removed the FxTailable class because with explicit return
statements, it's not useful anymore.
This was to resolve some circular dependencies with the portal code.
The most notable changees:
* FTextureID was moved from textures.h to doomtype.h because it is frequently needed in files that don't want to do anything with actual textures.
* split off the parts from p_maputl into a separate header.
* consolidated all blockmap related data into p_blockmap.h
* split off the polyobject parts into po_man.h
* FInterpolator depended on external references to prevent its content from getting GC'd.
* none of the pointers in the interpolation objects were declared to the GC.
The result of these issues was that changing anything about the life cycle of interpolation objects caused corrupted memory crashes when a level was changed.
- 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.
once in the level struct and then use that for sectors with a NULL skybox. This fixes zpack's
E2M3 so that when it removes its sector stacks, you will get the default skybox in their
place, since stacked sectors and skyboxes use the same pointers in a sector.

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)
- fixed: D_ErrorCleanup must clear 'savegamerestore'.
- fixed: Cleaning up when loading a savegame failed while restoring the thinker list did not work. There were two issues:
* removed the asserts in GC::SweepList because they get triggered by thinkers that were not fully initialized during loading.
* AActor::UnlinkFromWorld may not assume that the sector list has been initialized when this function is called.
SVN r3274 (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)
- 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)
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)
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)
thinkers tick, not just once every game tick. This more closely follows
the original Lua behavior. This change was made because, in cases of
extremely large and frequent memory allocations, the collector may not run
fast enough if it only has a chance to execute once per tick.
SVN r1197 (trunk)
- Fixed: Before a level's thinkers are loaded all previous interpolations must
be cleared.
- Fixed: deleted interpolations didn't NULL the pointer in the interpolated
object. Also added all interpolation pointers to DSectorMarker to ensure
that they are properyl processed by the garbage collector.
SVN r1028 (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)
it never freed. I'm not sure it's a good assumption that 9 characters is
always long enough, either, since you can have longer file names than that
inside a zip.
- Fixed: DSBarInfo::DrawGem() crashed if chain or gem was NULL.
SVN r929 (trunk)
that the drivers will treat a BackBufferCount of 0 as a request for
double buffering.
- Fixed: Unsetting a cvar did not remove it from the list of tab
completions.
- Added "" as a synonym for "nullimage" in SBARINFO.
- Fixed: MAKESAVESIG's stringifier in version.h did not work as expected.
It stringified the passed macro name, not the value of the macro.
- Moved DCajunMaster off the DObject hierarchy.
- Changed DCajunMaster::getspawned into a TArray of FStrings. It was
mysteriously being left pointing to uninitialized memory during the
final GC at exit and crashing.
- Fixed: The code that removed hexdd.wad from the list of IWADs when
hexen.wad was not present did not work.
SVN r861 (trunk)
- Removed movie volume from the sound menu and renamed some of the other
options to give the MIDI device name more room to display itself.
- Moved the midi device selection into the main sound menu.
- Added FMOD as MIDI device -1, to replace the MIDI mapper. This is still the
default device. By default, it uses exactly the same DLS instruments as the
Microsoft GS Wavetable Synth. If you have another set DLS level 1 patch set
you want to use, set the snd_midipatchfile cvar to specify where it should
load the instruments from.
- Changed the ProduceMIDI function to store its output into a TArray<BYTE>.
An overloaded version wraps around it to continue to supply file-writing
support for external Timidity++ usage.
- Added an FMOD credits banner to comply with their non-commercial license.
- Reimplemented the snd_buffersize cvar for the FMOD Ex sound system. Rather
than a time in ms, this is now the length in samples of the DSP buffer.
Also added the snd_buffercount cvar to offer complete control over the
call to FMOD::System::setDSPBufferSize(). Note that with any snd_samplerate
below about 44kHz, you will need to set snd_buffersize to avoid long
latencies.
- Reimplemented the snd_output cvar for the FMOD Ex sound system.
- Changed snd_samplerate default to 0. This now means to use the default
sample rate.
- Made snd_output, snd_output_format, snd_speakermode, snd_resampler, and
snd_hrtf available through the menu.
- Split the HRTF effect selection into its own cvar: snd_hrtf.
- Removed 96000 Hz option from the menu. It's still available through the
cvar, if desired.
- Fixed: If Windows sound init failed, retry with DirectSound. (Apparently,
WASAPI doesn't work with more than two speakers and PCM-Float output at the
same time.)
- Fixed: Area sounds only played from the front speakers once you got within
the 2D panning area.

list, it should just be ignored during the propagation stage.
- After sleeping on it and realizing what was really going in, I generalized
the inventory fix from the 13th: The actor is flagged by Destroy(), then it
is later inserted into the thinker list by DThinker::SerializeAll(). So
rather than unlinking the skipped player from their inventory, just make
sure any flagged thinkers aren't inserted into a list.
- Fixed: FCanvasTextureInfo::Viewpoint needed a read barrier, and the whole
list should serve as a root.
- Reimplemented SPC playback as a custom codec for FMOD.
- Removed spc_frequency, because snes_spc only supports the SPC's native
frequency of 32000 Hz.
