19b1c10ba8 - scriptified a large part of the weapon code. 2017-01-19 17:40:34 +01:00
Christoph Oelckers
f9441cd9d9 - added null pointer validation to any relevant exported function. In most cases null pointers were already being treated as 'do nothing', but there's several places where this can make the code silently fail so in these cases a VM exception will be raised, once the VM's exception handling has been repaired to provide useful diagnostics. (Right now all it does is catch the exception, print a useless message and return to the caller as if nothing has happened.) 2016-12-02 12:06:49 +01:00

7325e3f0f8 - exported all member fields that make sense. Entirely private ones or classes that are not supposed to be extended were left out. 2016-11-23 17:34:36 +01:00

135cfcf016 - implemented State as an actual native struct, so that its fields can be accessed from scripts.
- refactored state bitfield members into a flag word because the address of a bitfield cannot be taken, making such variables inaccessible to scripts.
- actually use PNativeStruct for representing native structs defined in a script.

360436c201 - scriptified the scripted marines.
- fixed symbol name generation for native functions.
- moved PrintableName to VMFunction so that native functions also have this information.

d86f03e2e0 - reverted most of the last commit after realizing that trying to manage constructing/destructing per variable is not going to work because it'd require some extensive exception management in the compiled VM code.
- 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.

633da6e5d8 - scriptified two of the Acolyte's functions.
- added a DActorIterator class.
- fixed: It was not possible to have functions of the same name in two different classes because the name they were searched for was not qualified by the class. Changed so that the class name is included now, but to avoid renaming several hundreds of functions all at once, if the search fails, it will repeat with 'Actor' as class name.

This commit contains preparations for scriptifying Hexen's Dragon, but that doesn't work yet so it's not included.

96d093d01f - added compile time checks for bad state links and state label references.
- preserve a state's source line information for the postprocessing phase so that the checker can output more useful information.
- added missing check for weapon psprites to DPSprite::SetState.

ac86a535e7 - fixed: State labels were resolved in the calling function's context instead of the called function one's.
This could cause problems with functions that take states as parameters but use them to set them internally instead of passing them through the A_Jump interface back to the caller, like A_Chase or A_LookEx.
This required some quite significant refactoring because the entire state resolution logic had been baked into the compiler which turned out to be a major maintenance problem.
Fixed this by adding a new builtin type 'statelabel'. This is an opaque identifier representing a state, with the actual data either directly encoded into the number for single label state or an index into a state information table.
The state resolution is now the task of the called function as it should always have remained. Note, that this required giving back the 'action' qualifier to most state jumping functions.

- refactored most A_Jump checkers to a two stage setup with a pure checker that returns a boolean and a scripted A_Jump wrapper, for some simpler checks the checker function was entirely omitted and calculated inline in the A_Jump function. It is strongly recommended to use the boolean checkers unless using an inline function invocation in a state as they lead to vastly clearer code and offer more flexibility.

- let Min() and Max() use the OP_MIN and OP_MAX opcodes. Although these were present, these function were implemented using some grossly inefficient branching tests.
- the DECORATE 'state' cast kludge will now actually call ResolveState because a state label is not a state and needs conversion.

9e2830a3db - converted the rest of actors/shared.
- moved damagetype definitions to MAPINFO. These were in DECORATE which is not correct. The old code is left for compatibility.

b1a83bfd26 - started with cleanup and separation of DECORATE code.
* 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.

c665cc53f9 - moved new code to its proper location and started moving the replaced old archive code to a placeholder file for easy removal later. 2016-09-19 10:34:54 +02:00

db86385cf6 - removed STACK_ARGS.
The only reason this even existed was that ZDoom's original VC projects used __fastcall. The CMake generated project do not, they stick to __cdecl.
Since no performance gain can be seen by using __fastcall the best course of action is to just remove all traces of it from the source and forget that it ever existed.

- 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.

dcc318fdee - print a warning when a state label can't be found. Preferably this would be an error but the oversight had been in the engine for too long so nobody knows 2014-10-25 12:33:08 +02:00

0e19a0e330 - Added a NODELAY state flag. This is only valid for a state immediately following a Spawn label.
When set, the actor will run this state during its first tick. This means Spawn
  states may now run an action function if you set this flag. Note that this action function
  is executed during the actor's first tick, which is not the same as when it is spawned.

22cc0544af - Fixed: FStateDefinitions::FinishStates() must ResolveGotoLabels before resolving labelled gotos. Otherwise, something like this fails:
Goto State1
    State1:
      Goto State2
    State2:
  because when "Goto State1" is processed, State1 is still pointing at the string "State2" rather than State2's state, so the goto will end up pointing at a string (which will soon be
  freed from memory) instead of at an actual state.

f0f17e531c - move static AM color initialization into the AM_StaticInit function.
- 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.)

178587fff2 - Merged SetState and SetStateNF into a single function.
- Added new sprite #### and frame character # to specify the behavior of sprite ---- on a
  per-sprite and per-frame basis respectively.

ee55e0319f - Standardized use of PClassActor::AllActorClasses for iterating over all classes of actors
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).

f88f601230 - Removed the third parameter from dumpclasses when it was restricted it to Actors, because
I have no idea what that was all about.

85cc335725 - Added dummy code generation for states that pass parameters to action functions.
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.

a3b11af15a - More GCC warning removal, the most egregious of which was the potential
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.

f8c38e5f54 - Made several DECORATE errors which do not involve parsing non-fatal.
- 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.

081658d3d5 - Fixed: The save percentage for Doom's green armor was slightly too low
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.

d753d41752 - Added NULL checks to all places where class names are passed as DECORATE
parameters.
- All DECORATE parameters are passed as expressions now. This change allows
  for compile time checks of all class names being used in DECORATE so many
  incorrect definitions may output warnings now.
- Changed DECORATE sound and color parameters to use expressions.
- Changed: S_StopChannel now resets the actor's sound flags. The previous bug
  made me think that delaying this until FMod calls the end of sound callback 
  may simply be too late.

handling of actor variables in expressions with it.
- Added support for floating point constants to DECORATE expression evaluator.

738e8ca7ad - GCC warning removal.
* This may or may not be a problem, but GCC warned that FStateDefinitions::
    AddStateDefines() does not initialize def.FStateDefine::DefineFlags, so
    I fixed that.

8d4912f4af - Fixed: The three-argument version of AActor::FindState() initialized a
two-entry array for passing to the main FindState() routine, but did
  not actually pass it, passing the original primary label instead.

Christoph Oelckers
954955c5a5 - Used the one unused byte in the state structure as a flag to tell what type
the NextState parameter is. The code did some rather unsafe checks with it
  to determine its type.
- moved all state related code into a new file: p_states.cpp.
- merged all FindState functions. All the different variations are now inlined
  and call the same function to do the real work.
