- 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 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.
- So now you can do something like this for an action:
{
if (health > 1000)
{
A_Scream;
}
else
{
A_XScream;
}
}
Yes, the braces are required. Because I see too many instances where
somebody writes an if statement in ACS and doesn't understand why it
doesn't work right because they forgot braces.
- Fixed: Not actually putting an action between { and } would crash.
- You can now call several actions from one frame by grouping them between
curly braces. i.e. :
POSS G 3 { A_Pain; A_Log("Ow! That hurt!"); }
I will probably add an `if (something) { blah; blah; } else { wah; wah; }`
construct later, but that's the extent of the munging I plan for DECORATE. The
real work goes to the scripting language, not here. But if this branch is
getting merged to master sooner than later, here's an immediate benefit
from it right now.
- 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.
- 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.
- 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.
- 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)
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)
- 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)
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)
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)
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)
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)
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)
- 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)
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.
