Since this is a non-standard function it's better kept to as few places as possible, so now DirEntryExists returns an additional flag to say what type an entry is and is being used nearly everywhere where stat was used, excluding a few low level parts in the POSIX code.
- now that the frame buffer stores its render time, the 'ms' return from I_GetTimeFrac is not needed anymore, we may just as well use the globally stored value instead.
The only feature this value was ever used for was texture warping.
Since this calls I_WaitVBL, which resets the frame time, it was essentially just like calling a real-time timer anyway and nothing in it required a specific 0-timepoint.
The same applies to the ZScript interface. All it needs is a millisecond-precise timer with no semantics attached.
* store the frame time in the current screen buffer from where all render code can access it.
* replace some uses of I_MSTime with I_FPSTime, because they should not use a per-frame timer. The only one left is the wipe code but even this doesn't look like it needs either a per-frame timer or a timer counting from the start of the playsim.
- moved timer definitions into their own header/source files. d_main is not the right place for this.
- removed some leftover cruft from the old timer code.
- Added: d_main.cpp now searches for "gzdoom_optional_assets.pk3" - this can be changed in version.h for fork authors.
- Updated forum links to point to ZDoom.org.
The old code went through a list of predefined file names and looked each of them up in a list of predefined directories until it found a match. This made it nearly impossible to add custom IWAD support because the list of valid file names could not be extended.
This has now been switched around to run a scan for matching files on each given directory. With this approach it can look for *.iwad and *.ipk3 as IWAD extensions as well and read an IWADINFO out of these files that can be added to the internal list of IWADs, making it finally possible to define custom IWADs without having to add them to the internal list.
(This isn't fully tested yet so some errors may still occur.)
This fixes two issues:
* timer related texture animations are not being recreated multiple times if a scene renders multiple viewpoints (e.g. camera textures or portals.)
* interpolation is smoother when maps have a high think time of multiple milliseconds. A good map to see the difference would be ZDCMP2 which has a think time of 4-5 milliseconds. With the timer taken in real time after the thinkers have run and VSync on this resulted in alternating time slices of 11 and 21 ms between frame interpolations instead of an even 16 as should be done for smooth 60 fps because roughly every second frame was offset by those 5 ms.
It now works the following way:
(0) - Force off (ZDoom defaults)
(1) - Force on (Doom defaults)
(2) - Auto off (Prefer ZDoom defaults - if DEHACKED is detected with no ZSCRIPT it will turn on) (default)
(3) - Auto on (Prefer Doom defaults - if DECORATE is detected with no ZSCRIPT it will turn off)
For some files that had the Doom Source license attached but saw heavy external contributions over the years I added a special note to license all original ZDoom code under BSD.
This is to ensure that the Class pointer can be set right on creation. ZDoom had always depended on handling this lazily which poses some problems for the VM.
So now there is a variadic Create<classtype> function taking care of that, but to ensure that it gets used, direct access to the new operator has been blocked.
This also neccessitated making DArgs a regular object because they get created before the type system is up. Since the few uses of DArgs are easily controllable this wasn't a big issue.
- did a bit of optimization on the bots' decision making whether to pick up a health item or not.
See https://forum.drdteam.org/viewtopic.php?t=7588
Processing order is now the same as in Chocolate Doom
prBoom+ loads separate files after all WAD lumps though
This makes sense but would change loading sequence existed in ZDoom for years
- activated the RenderOverlay event, now that it can be called from the correct spot, i.e. right after the top level HUD messages are drawn. The system's status output will still be drawn on top of them.
This allows using the UI scale or its own value, like all other scaling values.
In addition there is a choice between preserving equal pixel size or aspect ratio because the squashed non-corrected versions tend to look odd, but since proper scaling requires ununiform pixel sizes it is an option.
- changed how status bar sizes are being handled.
This has to recalculate all scaling and positioning factors, which can cause problems if the drawer leaves with some temporary values that do not reflect the status bar as a whole.
Changed it so that the status bar stores the base values and restores them after drawing is complete.
- better handling of ForceScale for the fullscreen HUD that doesn't mess around with CVARs.
- moved the mug shot into the status bar, because this is global state that needs to be shared between different pieces of code which want to display a mug shot.
- SBARINFO should work off the current status bar settings instead of the ones stored in its script object
- decided to ditch the widget system I had started to lay out. As it turns out that would make things far more complicated and slower than they need to be.
Note that the Strife status bar does not draw the health bars yet. I tried to replace the hacky custom texture with a single fill operation but had to find out that all the coordinate mangling for the status bar is being done deep in the video code. This needs to be fixed before this can be made to work.
Currently this is not usable in mods because they cannot initialize custom status bars yet.
Since the true color software renderer also handles them there is no point keeping them on the GL side.
This also optimized how they are stored, because we no longer need to be aware of a base engine which doesn't have them.
There's simply never enough of them and they are used far too infrequently to justify the hassle of tagging along two TMaps per class.
For what they provide, single global lists that handle all player classes at once are fully sufficient.
The math in DCanvas::FillBorder does not always work out so better clean the entire screen before drawing a fullscreen image to ensure that the menu blend is always drawn over something valid.
CVAR with this flag can be set in console or from command line when sv_cheats is enabled
There is no such restriction for changing its value from ACS, via SetCVar() and related functions
'cheat' modifier can be used in CVARINFO lump to create variable of this kind
The idea is, when status bars are moved to ZScript that only this small wrapper class needs to be dealt with and the implementation can be left alone. SBARINFO is far too complex to be scriptified, but having it inherit directly from DBaseStatusBar and access its member variables severely limits the options of dealing with the status bar code. This way, it only accesses some globally visible functions in DBaseStatusBar and no variables.
- renamed the global ST_X and ST_Y variables because it is far too confusing and error-prone to have the same names inside and outside DBaseStatusBar.
This was done to ensure it can be properly overridden in scripts without causing problems when called during engine shutdown for the type and symbol objects the VM needs to work and to have the scripted version always run first.
Since the scripted OnDestroy method never calls the native version - the native one is run after the scripted one - this can be simply skipped over during shutdown.
The original implementation just printed a mostly information-free message and then went on as if nothing has happened, making it ridiculously easy to write broken code and release it. Changed it to:
* Any VMAbortException will now terminate the game session and go back to the console.
* It will also print a VM stack trace with all open functions, including source file and line numbers pointing to the problem spots. For this the relevant information had to be added to the VMScriptFunction class.
An interesting effect here was that just throwing the exception object increased the VM's Exec function's stack size from 900 bytes to 70kb, because the compiler allocates a separate local buffer for every single instance of the exception object.
The obvious solution was to put this part into a subfunction so that it won't pollute the Exec function's own stack frame. Interesting side effect of this: Exec's stack requirement went down from 900 bytes to 600 bytes. This is still on the high side but already a lot better.
- 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.
- _FPU_GETCW is defined for more than just x87. Don't use it if the
control word for the target architecture doesn't support _FPU_EXTENDED
or _FPU_DOUBLE defined, e.g. pretty much anything but x87. If I had been
using glibc on PowerPC instead of Apple's libc, I probably would have
noticed this sooner, since _FPU_GETCW is part of glibc.
- handle a 'restart' CCMD a bit more controlled. Instead of throwing an exception in the CCMD handler it now just flags D_DoomLoop to return.
If the exception is thrown within the CCMD this can easily happen deep inside the renderer when it calls NetUpdate. But since the software renderer with its use of global variables is not equipped to be yanked out of lile this it could leave broken data behind that caused glitches or even crashes on subsequently played maps.
This cuts down on as much message noise as possible, outputs everything to a file specified as a parameter and then quits immediately, allowing this to run from a batch that's supposed to check a larger list of files for errors.
Multiple outputs get appended if the file already exists.
- This isn't a real file or even a name, but the game would try and load
it, including running through various permutations, potentially resulting
in loading the current directory as an archive.
This requires quite a bit more thorough cleanup. I got it to the point where the titlepic appears after restarting, but it still crashes when starting the game so there's more data that needs to be cleaned up...

UpdateSounds will not be called during screen wipes and the entire setup of this function suggests that this is not advisable at all.
The OpenAL stream updates were done deep inside this function implicitly.
This caused music to stop while a wipe was in progress. So in order to allow uninterrupted music playback during screen wipes the music updates need to be handled separately from sound updates and be called both in the main loop and the wipe loop.
I think that the OpenAL music updating should be offloaded to a separate thread but at least it's working now without causing interruptions during wipes.
- Old mess:
* Execute autoexec files right away.
* Execute -exec files right away.
* Execute command line commands right away.
- If, during any of the above, an unknown command or a set of an
unknown variable is encountered, store it for later.
- Pullin commands are directly executed and add to the list of files
to load.
* Do a little setup, including parsing CVARINFOs.
* Retry saved commands in case CVARINFO added a cvar they refer to.
- New, less messy, mess:
* Parse autoexec files into an array.
* Parse -exec files.
* Parse command line commands.
- During all of the above, exec commands are also parsed into the
array immediately rather than being saved for execution later.
- Pullin commands are parsed into a different array. The pullin
command doesn't actually do anything directly anymore.
* Add all the pullin files to the list of files to load.
* Do a little setup, including parsing CVARINFOs.
* Execute every command that was parsed in the preceding steps.
This has an important implication:
Previously the config was loaded before IWADINFO so in order to allow the config to access the data this had to be switched around.
This means that zdoom.pk3 will not be looked for in the global IWAD search paths anymore, but since it shouldn't be there to begin with it should be an acceptable compromise.
As a result the old 'Group' property could be removed and all other means to get a section name were disabled.
As an example, if the code gets 'doom.doom2.commercial' it will use the following sections in this order:
global.autoload
doom.autoload
doom.doom2.autoload
doom.doom2.commercial.autoload.
- Multi-directory archives (e.g. zips) now support filtering lumps
depending on the loaded IWAD. The search rules are the same as for the
Autoload entries in the user's ini. For instance, if you are playing
Doom 2, the following filters will be applied:
* "filter/doom2/*"
* "filter/doom/*"
They will be renamed to strip out the "filter/doom2/" and "filter/doom/"
parts and will be ordered so they take precedence over any files not
inside a filter/ directory. Any files inside another filter/ directory
(e.g. "filter/hexen/*") will be ignored.
- Fixed: Using +set cvarname and +cvarname on the command line would not
work if cvarname was defined in CVARINFO. This should be the proper way to fix
it. Rather than move all command line execution after loading CVARINFO,
keep command line execution before wads are loaded. If an attempt is
made to set an unknown cvar or to run an unknown command (which could
potentially be shorthand for setting an unknown cvar), save it and try
running it again after all CVARINFOs have been handled.

- Added register reuse to VMFunctionBuilder for FxPick's code emitter.
- Note to self: Need to reimplement IsPointerEqual and CheckClass, which
were added to thingdef_function.cpp over the past year, as this file no
longer exists in this branch.
Even when '+logfile' argument was omitted, the console would print 'Could not start log', because 'logfile != NULL' was used as a check for the presence of '+logfile' argument, but the internal buffer of FString is never NULL, so the right check is 'logfile.isNotEmpty()'.
While I'm at it, I fixed another bad check for 'pagename'.
- added version check for Windows 8. I also would have liked to add 8.1 but due to some incredibly stupid changes in the version API it's no longer possible to reliably retrieve the correct Windows version for later builds.
- Command-line console commands are executed before a level is entered, so
trying to use +warp to position yourself at a specific location will not
work. We now specially handle this command so that it does work.
- Fixed: You could not set any CVARINFO-defined cvars from the command line
because command line console commands were executed before wads were
even loaded. Off the top of my head, I can't think of anything that would\
break by having them get executed after wads are loaded.
The 'unix' identifier isn't defined when '-std' is passed to the compiler (tested with gcc and clang), so use '__unix__' which is well enough documented.
- Separated CVAR_MODARCHIVE into CVAR_MOD|CVAR_ARCHIVE so that mod-defined cvars can still be
identified when they aren't meant to be archived.
SVN r4281 (trunk)
of the form:
<scope> [noarchive] <type> <name> [= <defaultvalue>];
Where <scope> is one of:
* server: This cvar is shared by all players, and in network games, only select players can
change it.
* user: Each player has their own copy of this cvar, which they can change independently.
To prevent the cvar from being written to the config file, add noarchive to its definition.
<Type> is one of:
* int: An integral value. Defaults to 0.
* float: A value that can include a fraction. Defaults to 0.0.
* color: A color value. Default to black ("00 00 00").
* bool: A boolean value that can hold either true or false. Defaults to false.
* string: A string value. It's not too useful for mods but is included for completeness. Defaults to "".
<Name> is the cvar's name and must begin with a letter and may only include alphanumeric
characters and the underscore character.
If you wish a non-standard default add an = character after the cvar's name followed by the
default value you want to use. Example:
server int mymod_coolness = 10;
- Fixed: FStringCVar::SetGenericRepDefault() did not make a copy of the input string.

* HUDMSG_NOTWITH3DVIEW : This message does not appear when the 3D view is active.
* HUDMSG_NOTWITHFULLMAP : This message does not appear when the fullscreen automap is active.
* HUDMSG_NOTWITHOVERLAYMAP : This message does not appear when the overlay automap is active.
These flags may be combined, so for example: HUDMSG_NOTWITHFULLMAP | HUDMSG_NOTWITHOVERLAYMAP
would prevent the message from appearing if any form of automap is active.
- Added HUD message layers, which are ORed into the type field:
* HUDMSG_LAYER_OVERHUD : This is the default and standard behavior. The message appear on
top of most HUD elements. This definition is just included for completeness' sake; you
don't need to explicitly use it.
* HUDMSG_LAYER_UNDERHUD : The message appears underneath other HUD elements, such as the status bar.
* HUDMSG_LAYER_OVERMAP : The message appears on top of the fullscreen automap. At the moment,
this layer is functionally equivalent to using the flags HUDMSG_NOTWITH3DVIEW | HUDMSG_NOTWITHOVERLAYMAP.
However, if Blzut3 decides to implement support for drawing the automap permanently on a
second screen, messages on this layer will move to that screen with the automap and be permanently
visible as long as the map is visible on that other screen.
These are not flags, so for example HUDMSG_LAYER_UNDERHUD | HUDMSG_LAYER_OVERHUD is not valid.

- Fixed: If FCompressedMemFile::Reopen() fails, then it would try to double-free memory when deleted.

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)
- 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.

- 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)
- moved all code and data for Build tile management into FTextureManager.
- moved texture animation management into FTextureManager.

- Restored some original Doom behavior that received complaints from users:

* re-added the original hitscan checking code using a cross-section of the actor instead of the bounding box, compatibility optioned with COMPATF_HITSCAN.
SVN r2340 (trunk)
* Fixed: Trying to use a response file would result in infinite looping until memory was
exhausted.
* Fixed: Response files were read after coalescing file parameters, which would lead to
non-coalesced parameters if the original command line and response file both had them.
* You can now use more than one response file.
* Response files can include other response files.

instead of PClass::m_Types (now PClass::AllClasses).
- Removed ClassIndex from PClass. It was only needed by FArchive, and maps take care of the

all files loaded with '-file' are scanned for this lump. This lump is read
before any WAD initialization takes place, in particular the IWAD is not yet

everything that eventually calls D_AddFile. Also create the list of files

time as the polled timer so that the timer does not start running until the
first time it is used.

timer running prematurely, and we never call rand() anywhere. (Not to

pointless.)
SVN r1974 (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)
- 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.
