Christoph Oelckers 1e01e6e4df - record all line numbers during function generation. This is useful for error reporting and eventually debugging.
- throw a useful exception when a VM abort occurs, the simple enum was incapable of reporting anything more than the barest minimum, which at least for array index out of bounds errors was insufficient.

The current exception mechanism is still insufficient. It really has to report a proper crash location and print a stack trace to the maximum extent possible. Instead it just prints a message and happily goes on. This is not a good solution.

Christoph Oelckers f238f0ba5c - try to preserve a bit more information about incorrect use of user variables to print more meaningful error messages. This is not complete yet and will need integration with the previous commit. 2016-11-13 12:02:41 +01:00
Christoph Oelckers 2cb5839c11 - count errors in the parser and abort afterward if there were some.
- use FScriptPosition's error counter throughout the compiler so that there is only one counter for everything, not two.

Parts of the compiler use FScriptPosition, so this is easier to handle than having a separate counter in the compiler class. It also avoids having to pass the compiler object to any function where an error may be output. The TreeNodes contain sufficient data to be converted to an FScriptPosition and using that for error message formatting.

Christoph Oelckers 3b19887637 - implemented the Defaults property initializer.
This uses the same property and flag tables as DECORATE with a few changes:

 * it sets the parse mode to strict, so that several DECORATE warnings are now errors.
 * trying to change a deprecated flag will print a warning.
 * setting of editor numbers, spawn and conversation ID id not possible. Use MAPINFO to do this.
 * all subclass flags must use the qualified name now (e.g. +ALWAYSPICKUP will print an error.)
 * the scriptable Damage property is not yet implemented. This will require a special case with a differently named property in the processing function because in the AST it is no longer possible to distinguish between a damage value and a constant damage function.

Christoph Oelckers e04055dbb2 - added multiple message levels for 'developer' CVAR so that the important stuff won't get drowned in pointless notification spam that's of no use to anyone.
- made 'developer' CVAR persist across launches and added some menu entries for it.
- added checks for 'developer' to ACS's CheckInventory function.
2016-08-28 09:55:04 +02:00
Christoph Oelckers ef86b3975a - added 'strictdecorate' CVAR. If this is set to 'true', any DECORATE error that had to be demoted to a warning for backwards compatibility will be treated as an actual error. 2016-06-08 10:56:11 +02:00
Christoph Oelckers 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.

Randy Heit 964ff46063 Add new state options to parser and actually enable them
- Added new state options that DECORATE got to the lemon parser.
- Enable token generation for state options. They were previously not
  generated, so the grammar treated them as function calls instead.

Christoph Oelckers e88901f4b7 - added the EE-Extradata parser I wrote for GZDoom so I can use the Vaporware demo map for testing portal stuff. 2016-02-05 23:51:28 +01:00

Randy Heit 33344201fa Let the scanner returned unsigned integers

Christoph Oelckers 5be9729872 - FScanner::Float is a double so there's no need to cast values to float before assigning them to this variable.

Randy Heit 99670b708c - Sync scripting branch with what was in trunk on Sunday. I believe that would be revision 2739.

Randy Heit f24c0cf292 - Merge scanner changes from the scripting branch, since I'm pretty sure the
token names were out of sync here, too.



SVN r2209 (trunk)
2010-03-14 04:03:07 +00:00
Randy Heit e489867c18 - Changed some tokens and split the token definitions into a separate file so
that their symbol names and their string names can be maintained in the same
  place.



SVN r2207 (scripting)
2010-03-13 03:28:34 +00:00
Christoph Oelckers 238d4c3fac - More things from Gez's experimental build:
* info CCMD to print extended actor information (not fully implemented yet)
  * summonmbf CCMD.
  * Beta BFG code pointer (but not the related missiles yet.)
  * PowerInvisibility enhancements.
  * ScoreItem with one significant change: Added a score variable that can be
    checked through ACS and DECORATE. The engine itself will do nothing with it.
  * Nailgun option for A_Explode.
  * A_PrintBold and A_Log.
  * A_SetSpecial.


SVN r1819 (trunk)
2009-09-14 19:44:14 +00:00
Christoph Oelckers a732687548 - Changed APlayerPawn::DamageFade to a PalEntry from 3 floats.
- Removed #pragma warnings from cmdlib.h and fixed the places where they were 
  still triggered.
  These #pragmas were responsible for >90% of the GCC warnings that were not
  listed in VC++.
- Fixed one bug in the process: DSeqNode::m_Atten was never adjusted when the
  parameter handling of the sound functions for attenuation was changed.
  Changed m_Atten to a float and fixed the SNDSEQ parser to set proper values. 
  Also added the option to specify attenuation with direct values in addition 
  to the predefined names.

SVN r1583 (trunk)
2009-05-15 10:39:40 +00:00
Randy Heit 75b7db858f - Added support for zip/pk3 files with LZMA and bzip2 compression to ZDoom.
- Added more output to zipdir and a -q option to turn it off.
- Added -u option to zipdir to only recompress those files in a zip that have
  changed. 
- Added -d and -f options to zipdir. -d forces deflate compression, and -f
  forces a write of the zip, even if it's newer than all the files it contains.
- Added support for bzip2 and LZMA compression to zipdir.


SVN r1468 (trunk)
2009-03-10 23:07:37 +00:00
Christoph Oelckers 666e40c8bb - Added MF5_CANTSEEK flag to prevent seeker missiles from homing in on
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)
2009-02-19 14:36:37 +00:00
Christoph Oelckers 4bcd3faef8 - moved all code related to global ACS variables to p_acs.cpp where it belongs.
- fixed: The nextmap and nextsecret CCMDs need to call G_DeferedInitNew instead of G_InitNew.
- merged MAPINFO branch back into trunk.

SVN r1393 (trunk)
2009-02-03 19:11:43 +00:00
Christoph Oelckers 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.


SVN r1334 (trunk)
2008-12-29 23:03:38 +00:00
Christoph Oelckers 11d1c41873 - Added a strbin1 function that does the same as strbin but creates a copy
instead of overwriting the original string. ACS performing this operation
  in place caused crashes with RTC-3057.
- fixed: FScriptPosition::Message did not print the message if it was not 
  a fatal error.


SVN r1313 (trunk)
2008-12-07 17:50:03 +00:00
Christoph Oelckers 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.

SVN r1312 (trunk)
2008-12-07 12:11:59 +00:00
Christoph Oelckers 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.


SVN r1276 (trunk)
2008-10-25 17:38:00 +00:00
Christoph Oelckers b9afb78523 - Added native variables to expression evaluator and replaced the previous
handling of actor variables in expressions with it.
- Added support for floating point constants to DECORATE expression evaluator.

SVN r1271 (trunk)
2008-10-19 21:43:36 +00:00
Christoph Oelckers d9ab611db2 - Fixed: Powerup.Color's handler contained an unnecessary 'else' which resulted
in opaque powerup blends.

SVN r1252 (trunk)
2008-10-05 08:50:47 +00:00
Christoph Oelckers 6227906072 - Fixed: SNDINFO must be loaded before the textures. However, this required
some changes to the MAPINFO parser which tried to access the texture manager
  to check if the level name patches exist. That check had to be moved to
  where the intermission screen is set up.
- Fixed: 'bloodcolor' ignored the first parameter value when given a list
  of integers.
  Please note that this creates an incompatibility between old and new 
  versions so if you want to create something that works with both 2.2.0
  and current versions better use the string format version for the color
  parameter!
- Rewrote the DECORATE property parser so that the parser is completely
  separated from the property handlers. This should allow reuse of all 
  the handler code for a new format if Doomscript requires one.
- Fixed: PClass::InitializeActorInfo copied too many bytes if a subclass's
  defaults were larger than the parent's.
- Moved A_ChangeFlag to thingdef_codeptr.cpp.
- Moved translation related code from thingdef_properties.cpp to r_translate.cpp
  and rewrote the translation parser to use FScanner instead of strtol.
- replaced DECORATE's 'alpha default' by 'defaultalpha' for consistency.
  Since this was never used outside zdoom.pk3 it's not critical.
- Removed support for game specific pickup messages because the only thing
  this was ever used for - Raven's invulnerability item - has already been
  split up into a Heretic and Hexen version.

SVN r1240 (trunk)
2008-09-21 18:02:38 +00:00
Christoph Oelckers 65a19e4be7 - Changed the action function declaration parser so that optional parameters
can be given a default value. The 'optional' keyword is no longer needed
  and was removed, as well as 'evalnot'.


SVN r1164 (trunk)
2008-08-12 20:19:47 +00:00
Christoph Oelckers 0ad1bfe87e - Added Gez's dropammofactor submission with some necessary changes. Also merged
redundant ammo multiplication code from P_DropItem and ADehackedPickup::TryPickup.
- Restricted native action function definitions to zdoom.pk3.


SVN r1123 (trunk)
2008-08-07 08:18:48 +00:00
Christoph Oelckers 82dbebc3f1 - Removed some unused constant definitions from sc_man.cpp.
- Fixed: A_FireBlasterPL2 played the weapon sound with the missile as origin
  instead of the shooting player.


SVN r1053 (trunk)
2008-06-28 21:46:26 +00:00
Christoph Oelckers ab6b5e337e - Reworked a few options that previously depended on LEVEL_HEXENFORMAT
(actors being forced to the ground by instantly moving sectors, strife
  railing handling and shooting lines with a non-zero but unassigned tag.)
  With UDMF such semantics have to be handled diffently. 
- finalized UDMF 1.0 implementation.
- Added Martin Howe's latest morph update.


SVN r987 (trunk)
2008-05-22 19:35:38 +00:00
Randy Heit d2c275bbb3 - Changed FScanner so that opening a lump gives the complete wad+lump name
rather than a generic one, so identifying errors among files that all have
  the same lump name no longer involves any degree of guesswork in
  determining exactly which file the error occurred in.
- Added a check to S_ParseSndSeq() for SNDSEQ lumps with unterminated final
  sequences.
- Fixed: Parts of s_sndseq.cpp that scan the Sequences array need NULL
  pointer checks, in case an improper sequence was encountered during
  parsing but not early enough to avoid creating a slot for it in the array.


SVN r874 (trunk)
2008-04-03 03:19:21 +00:00
Christoph Oelckers d5c3693fd9 - Added SnowKate709's A_DamageMaster/A_DamageChildren patch.
- Added a SFX_TRANSFERAMBUSHFLAG for A_SpawnItemEx.
- Added "Shaded" as a valid parameter for DECORATE's RenderStyle.
- Added Karate Chris's patch for a MAPINFO option making Strife conversations
  not halt the game.
- Extended the $limit fix that $alias and $random definitions can have their
  own $limit now.
- Fixed: When resolving a linked sound the limit of the current sound was
  ignored and the one of the referenced sound being used. This was particularly
  noticable when using the chaingun in a group of Zombiemen.
- Added a namespc parameter to FWadCollection::CheckNumForFullName which is
  used when a normal lump name has to be looked up and changed all
  CheckNumForFullName/CheckNumForName combinations in the source to use
  the extended version of CheckNumForFullName only to have consistent
  behavior for lump name lookup. 

SVN r865 (trunk)
2008-03-29 22:59:41 +00:00
Randy Heit 3237c6b4e8 - Changed MIDI playback to not bother playing super short songs that don't
contain enough music to fill the initial output buffers.
- Removed the read barrier around ADehackedPickup::RealPickup. If the real
  pickup is picked up, it may very well destroy itself before the dehacked
  wrapper's stubs that use it are called.
- Reverted revision 840. For a file we don't want end users to be touching,
  making DEHSUPP plain text sends out mixed messages: "Don't mess with this.
  Oh, by the way, it's plain text now to make it easier for you to edit."
  Is there some reason other than a desire to do away with binary lumps to
  make the distributed lump text?
- Added a new speakermode for Stereo + HRTF: "Headphones". This is the only
  way to get the HRTF low pass filter effect now.
- Fixed: No more than one sector could make noise at once.
- Trying out sound without varying priorities again. 
- Fixed: Need to use setSpeakerMix to let 2D sounds (aka streamed music) use
  their full volume range.


SVN r842 (trunk)
2008-03-23 05:24:40 +00:00
Christoph Oelckers 9c1fa19dd2 - Changed DEHSUPP loader so that it reads the text file directly. As a result
the DEHSUPP compiler is gone now. Unlike XLATCC I'm using FScanner though.
  A fully featured parser seems like overkill for this simple text file.


SVN r840 (trunk)
2008-03-22 21:07:31 +00:00
Randy Heit e5572a1c4e - Updated lempar.c to v1.31.
- Added .txt files to the list of types (wad, zip, and pk3) that can be
  loaded without listing them after -file.
- Fonts that are created by the ACS setfont command to wrap a texture now
  support animated textures.
- FON2 fonts can now use their full palette for CR_UNTRANSLATED when drawn
  with the hardware 2D path instead of being restricted to the game palette.
- Fixed: Toggling vid_vsync would reset the displayed fullscreen gamma to 1
  on a Radeon 9000.
- Added back the off-by-one palette handling, but in a much more limited
  scope than before. The skipped entry is assumed to always be at 248, and
  it is assumed that all Shader Model 1.4 cards suffer from this. That's
  because all SM1.4 cards are based on variants of the ATI R200 core, and the
  RV250 in a Radeon 9000 craps up like this. I see no reason to assume that
  other flavors of the R200 are any different. (Interesting note: With the
  Radeon 9000, D3DTADDRESS_CLAMP is an invalid address mode when using the
  debug Direct3D 9 runtime, but it works perfectly fine with the retail
  Direct3D 9 runtime.) (Insight: The R200 probably uses bytes for all its
  math inside pixel shaders. That would explain perfectly why I can't use
  constants greater than 1 with PS1.4 and why it can't do an exact mapping to
  every entry in the color palette.
- Fixed: The software shaded drawer did not work for 2D, because its selected
  "color"map was replaced with the identitymap before being used.
- Fixed: I cannot use Printf to output messages before the framebuffer was
  completely setup, meaning that Shader Model 1.4 cards could not change
  resolution.
- I have decided to let remap palettes specify variable alpha values for
  their colors. D3DFB no longer forces them to 255.
- Updated re2c to version 0.12.3.
- Fixed: A_Wander used threshold as a timer, when it should have used
  reactiontime.
- Fixed: A_CustomRailgun would not fire at all for actors without a target
  when the aim parameter was disabled.
- Made the warp command work in multiplayer, again courtesy of Karate Chris.
- Fixed: Trying to spawn a bot while not in a game made for a crashing time.
  (Patch courtesy of Karate Chris.)
- Removed some floating point math from hu_scores.cpp that somebody's GCC
  gave warnings for (not mine, though).
- Fixed: The SBarInfo drawbar command crashed if the sprite image was
  unavailable.
- Fixed: FString::operator=(const char *) did not release its old buffer when
  being assigned to the null string.
- The scanner no longer has an upper limit on the length of strings it
  accepts, though short strings will be faster than long ones.
- Moved all the text scanning functions into a class. Mainly, this means that
  multiple script scanner states can be stored without being forced to do so
  recursively. I think I might be taking advantage of that in the near
  future. Possibly. Maybe.
- Removed some potential buffer overflows from the decal parser.
- Applied Blzut3's SBARINFO update #9:
  * Fixed: When using even length values in drawnumber it would cap to a 98
    value instead of a 99 as intended.
  * The SBarInfo parser can now accept negatives for coordinates. This
    doesn't allow much right now, but later I plan to add better fullscreen
    hud support in which the negatives will be more useful. This also cleans
    up the source a bit since all calls for (x, y) coordinates are with the
    function getCoordinates().
- Added support for stencilling actors.
- Added support for non-black colors specified with DTA_ColorOverlay to the
  software renderer.
- Fixed: The inverse, gold, red, and green fixed colormaps each allocated
  space for 32 different colormaps, even though each only used the first one.
- Added two new blending flags to make reverse subtract blending more useful:
  STYLEF_InvertSource and STYLEF_InvertOverlay. These invert the color that
  gets blended with the background, since that seems like a good idea for
  reverse subtraction. They also work with the other two blending operations.
- Added subtract and reverse subtract blending operations to the renderer.
  Since the ERenderStyle enumeration was getting rather unwieldy, I converted
  it into a new FRenderStyle structure that lets each parameter of the
  blending equation be set separately. This simplified the set up for the
  blend quite a bit, and it means a number of new combinations are available
  by setting the parameters properly.


SVN r710 (trunk)
2008-01-25 23:57:44 +00:00
Christoph Oelckers b8827b1b86 - Fixed: There was no working means to pass 'no state' to A_Chase.
Now 0 or an empty string will do that.
- Copied the empty string fix for SC_CheckNumber to SC_CheckFloat.

SVN r591 (trunk)
2007-12-09 09:54:58 +00:00
Randy Heit 351ed8dcd1 - Changed the PowerTimeFreezer "blink" effect back to checking against
EffectTics (now + 1), because I wasn't convinced of the correctness of
  using level.time.
- Fixed: SC_CheckNumber() considered the empty string "" as the number 0.


SVN r586 (trunk)
2007-12-08 22:29:59 +00:00
Christoph Oelckers 3b477d7022 - Fixed: POwered up weapons with a different ready state than their base
weapon didn't change back when the powerup expired.
- Fixed: The powered up version of Heretic's Gauntlets missed the proper
  state assignments for Ready, Lower and Raise.
- Fixed: The Strife player was missing its pain state.
- Fixed: Revenant missiles couldn't home in on targets with a height lower than
  40.
- Fixed: The code which checked for hitscan traces hitting actors from above
  and below must test whether the calculated hit position is actually inside 
  the actor being checked. If it crosses the top/bottom plane outside the
  bounding box there can't be a hit.
- Changed: State labels in code pointer calls must now be enclosed in quotation marks.
  This was done to ensure compatibility with parsers that will parse these as
  identifier-aware script code later.


SVN r554 (trunk)
2007-10-19 08:49:02 +00:00
Christoph Oelckers 90db40c70f - Fixed: Tne Imp's raise state sequence was wrong due to a typo.
- Fixed: The shotgun had spawn ID 21 instead of 27.
- Fixed: All 3 states in the DoomUnusedStates actor need to end with a 'stop'.
- Fixed: The DECORATE TakeInventory functions didn't check the IF_KEEPDEPLETED
  flag.
- Fixed: ClearInventory should leave ammo in the inventory because it might be
  referenced by undroppable weapons.
- Fixed: Several functions in a_artifacts.cpp were missing a check for a valid
  owner.
- Fixed: sc_man counted lines wrong when ungetting strings but getting tokens
  next.



SVN r552 (trunk)
2007-10-05 08:04:38 +00:00
Christoph Oelckers 50f75b6e8a - Fixed: deadthings.txt contained a superfluous ';' which created parsing errors
with my changed code.
- Cleaned up DECORATE parser a little - moved the old style parsing code into its 
  own file and rearranged a few things.
- Made ProcessStates non-static so that it doesn't need to be passed as an argument
  to all functions in the DECORATE parser.
- Moved DECORATE parser files into their own subdirectory.
- Optimization: SC_GetToken no longer sets sc_name for identifiers. In most cases
  this creates needless overhead by adding a potentially unneeded name to the name
  table and looking up the name. In almost all cases where a name is needed it's as
  easy to assign sc_String to the name variable.
- Added enum definitions to DECORATE.
