- created script exports for all relevant functions with all integral types.
- created script side definitions for the underlying data types.
- added a void pointer type so that the prototype for the pointer array can use a generic type every pointer can be assigned to.
- for explicitly defined glows, use the one for the current animation frame, if an animated texture is active. For default glows it will still use the base texture's to avoid inconsistencies.
* It will now use #include, just like most other definition formats and can be mixed with regular definitions. However, due to how the Lemon-generated parser works this will not recursively pull in all files, but store them in a list and process them sequentially. Functionally this shouldn't make a difference, because ZScript is mostly order-independent - the only thing where order is important is native classes, but these are completely internal to zdoom.pk3 where proper order is observed.
- fixed: Assignment from a readonly to a read-allowed pointer must be an error.
- made GetDefaultByType a builtin so that it can do proper type assignment to the result, which for a function would be problematic in this case, even if automatic type deduction was implemented. Since this returns the class defaults which are not a real object, the result cannot be subjected to a type cast.
- error out if a type cast of a readonly pointer is attempted.
- fixed: FxBooleanNot could clobber a local variable because it used the source register to manipulate the result.
- fixed issues with the refactoring of the recent commits. This one starts again.
- added builtins for TextureID.
Note about builtins: Currently they are just hacked into the compiler backend. They really should be made part of the respective types to keep matters clean and allow more widespread use of builtins to create more efficient code.
- Took the opportunity and fixed the logic for the Skull Rod's rain spawner. The old code which was part of the 3D floor submission was unable to work with portals at all. The new approach no longer tries to hide the dead projectile in the ceiling, it leaves it where it is and changes a few flags, so that its z-position can be used as reference to get the actual ceiling. This works for line portals, but for sector portals still requires some changes to sector_t::NextHighestCeilingAt to work, but at least this can be made to work unlike the old code.
- added names for the player-related translations to A_SetTranslation.
- fixed: Failure to resolve a function argument was checked for, too late.
- made the parameter for A_SetTranslation a name instead of a string, because it is more efficient. We do not need full strings here.
- scriptified all Effect functions of Fastprojectile's children
- implemented access to class meta data.
- added a VM instruction to retrieve the class metadata, to eliminate the overhead of the function call that would otherwise be needed.
- made GetClass() a builtin so that it can use the new instruction
Important note about this commit: Scriptifying CFlameMissile::Effect revealed a problem with the virtual function interface: In order to work, this needs to be explicitly enabled for each single native class that may be used as a base for a scripted class. Needless to say, this will end up way too much work, as there are over 100 native classes, excluding those which will be scriptified. But in order to fix the problem this partially broken state needs to be committed first.
- fixed: FxAssignSelf did not the correct number of registers for vector operations.
- fixed a few asserts in vector2 instructions.
- turned the virtual AActor::HitFloor method into a flag MF7_SMASHABLE. The only use of this function was to kill Hexen's pottery when they hit the floor, and this looks like something that can be exposed to modders less clumsily.
- added new VARF_Transient flag so that the decision whether to serialize a field does not depend solely on its native status. It may actually make a lot of sense to use the auto-serializer for native fields, too, as this would eliminate a lot of maintenance code.
- defined (u)int8/16 as aliases to the byte and short types (Can't we not just get rid of this naming convention already...?)
- exporting the fields of Actor revealed a few name clashes between them and some global types, so Actor.Sector was renamed to CurSector and Actor.Inventory was renamed to Actor.Inv.
- changed Dehacked weapon function lookup to check the symbol table instead of directly referencing the VM functions. Once scriptified these pointers will no longer be available.
- removed all special ATAGs from the VM. While well intentioned any pointer tagged with them is basically unusable because it'd trigger asserts all over the place.
- scriptified A_Punch for testing pass-by-reference parameters and stack variables.
- added state usage specifiers to Actor and Inventory. The states in these classes must be set to full access so that any existing mod can link to them.
This appears to be the only case where an actor was set to a state owned by a completely unrelated actor which would present some problems with state owner checking in AActor::SetState, so let's better get rid of it ASAP.
I believe the only reason this wasn't changed when all actors were exported 8 years ago was that old binary DEHSUPP lump.
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.
Added two new sub-blocks for Choice blocks: Require and Exclude.
The syntax for both is the same as Cost blocks.
Require defines what item must be present in your inventory in order to show this choice/reply.
Exclude defines what item must not be present in your inventory in order to show this choice/reply.
If any Require/Exclude blocks are defined then this choice/reply will be hidden until all blocks of both types are satisfied.
- removed the bogus optional value from the first A_Jump argument. A quick test with an older ZDoom revealed that this was never working - and implementing it would make things a lot more complicated, especially error checking in the code generator.
- fixed: The check for insufficient parameters to a function call was missing.
- added initializer syntax for vectors. A vector can be set with vectorvar = (x,y,z); for a 3-dimensional vector and vectorvar = (x, y); for a 2-dimensional one.
- added master and tracer to the list of exported variables.
- fixed: 'none' as class type must map to the real null pointer so that it won't get rejected by the stricter type checks.
- added handling for member function calls to zcc_compile.cpp.
- fixed: FxMemberFunctionCall may not delete the self expression if it gets passed on to the actual function call.
* Allow PFunction to work without a VMFunction being attached.
* The Variant for a function must store the prototype itself instead of relying on the VMFunction it points to. Otherwise it would not be possible to reference a prototype during compilation of the function because it does not exist yet.
* Give the variant a list of the function's argument's names, because these are also needed to compile the function.
* create an anonymous function symbol when the function gets registered to the builder. At this point we have all the needed information to set it up correctly, but later this is no longer the case. This is the most convenient info to have here because it contains everything that's needed to compile the function in the proper context, so it has to be present when starting compilation.
* added some preparations to implement special handling for weapons and custom inventory items, which can run action functions in another actor's context. This part is not active yet but the basics are present in SetImplicitArgs.
- switched the types of the internal 'self' and 'stateowner' parameters so that they get assigned correctly. I can't tell if this will error out if fields get accessed from the caller with the wrong class, but for actual scripting to work these must be correct.
The committed 'actor.txt' can be parsed successfully, with the exception of a few subclass references that cannot be resolved yet.
The state is undefined by default to preserve the original behavior of having the weapon layer deleted which modders can now avoid by defining it properly
- DECORATE now has atan2(y,x) and VectorAngle(x,y) functions. They are
identical except for the order of their parameters. The returned angle
is in degrees (not radians).
- Split specific parsing for each intrinsic out of ParseExpression0 and
into their own functions.
- Instead of reserving keywords for intrinsics, identify them by name
within TK_Identifier's handling.
- This is an effort to emphasize that these are just type casts. Now they
look like function-style casts with no action function styling.
They do no magic joojoo at all. The only reason they exist is because
the DECORATE parser can only parse return statements that call a
function, so these satisfy that requirement. i.e. *return int(666);* is
identical to *return 666;* (if the parser could handle the latter).
'ceilingterrain' is needed because the top of 3D-floors refers to the model sector's ceiling, so in order to give a 3D floor a terrain it must be assignable to the sector's ceiling.
Note that although it is basically the same property, its actual function bears no relevance to its use in Eternity.
- major overhaul of the static sector damage system:
* consolidated special based damage, Sector_SetDamage and UDMF properties into one set of damage properties. The parallel handling that could lead to double damage infliction was removed. This also means that damage through sector specials can be retroactively changed through Sector_SetDamage.
* all special cases were turned into flags. The new system can switch between Strife's delayed damage and regular damage, and it can also set whether terrain splashes are used or not. It also has access to the special properties of the end-level type (i.e. switching off god mode and ending the level.)
* the damage related flags are accessible through Sector_ChangeFlags, not the damage functions themselves.
- Added 'threshold' and 'defthreshold' to DECORATE expression exposure.
- ChaseThreshold sets the default threshold for how long a monster must chase one target before it can switch targets. Default is 100, must not be negative.
- A_SetChaseThreshold can be used to alter the current or default threshold of an actor <pointer>.
- Changing current threshold has no effect on what the default will be once it hits 0 and something makes it infight with another.
Tags are now handled by a tag manager class which stores sector/tag pairs. This way multiple entries can be added per sector.
Since UDMF does not have any arrays the additional tags are stored as a space separated string as 'MoreIDs'.
- Member variables are now declared all in one place: InitThingdef(). They
are not partially defined in thingdef_expression.cpp and further refined
in actor.txt.
- This left ParseNativeVariable() parsing only functions, so it has been
renamed to ParseNativeFunction().
- Note that their declarations in InitThingdef() are expected to be
temporary.

- 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.
Decorate: IsPointerEqual(int aaptr_selector1, int aaptr_selector2)
ACS: IsPointerEqual(int aaptr_selector1, int aaptr_selector2, int tid1 = 0, int tid2 = 0)
Compare the pointers values returned by two pointer select operations. Returns true if they both resolve to the same value. Null values can be explicitly tested using IsPointerEqual(AAPTR_NULL, ...)
ACS: IsPointerEqual(int aaptr1, int aaptr2, int tid1 = 0, int tid2 = 0)
This function lets you compare pointers from other actors than the activator, using tids. Tid1 determines the actor used to resolve aaptr1, Tid2 does the same for aaptr2. If tid1 and tid2 are equal, the same actor will be used for resolving both pointers (that could always happen randomly; this way you know it will happen).
- Make wi_noautostartmap a userinfo cvar. This allows it to be
communicated across the network and saved in demos. If any player has it
set, then the intermission screen will not automatically advance to the
next level.
DECORATE). Then you can use:
* Bounce
* Bounce.Floor
* Bounce.Ceiling
* Bounce.Wall
* Bounce.Actor
* Bounce.Actor.Creature
Partial matches work just like Pain states, so if an actor bounces off a floor and you don't
have a Bounce.Floor state, but you do have a Bounce state, it will use the Bounce state.
Conversely, if you only have a Bounce.Floor state but no Bounce state, then the actor will
only enter the Bounce.Floor state when it bounces on a floor; bouncing off anything else will
not cause it to change state.
SVN r4250 (trunk)
one name in its label. This avoids the alloca and security cookie calls.
- Consolidated lots of copy-pasted code in thingdef_expression.cpp to install helper functions
into FindDecorateBuiltinFunction().
SVN r3907 (scripting)
overridden in custom player classes by changing their Obituary property to something else.
- ClientObituary() now only looks up the obituary message from the killing player's weapon if the
damage type was 'Melee' or 'Hitscan'.
- Gave P_GunShot() and A_FireBullets the new damage type 'Hitscan'.
- Switched A_Saw and A_CustomPunch to the 'Melee' damage type.
SVN r3646 (trunk)
(i.e. ACS_Execute, etc.), set the arg0str property to the name of the script to execute. The
standard numeric arg0 property will be ignored in this case.
SVN r3372 (trunk)
- added Sector_SetTranslucent special so set translucency of portal planes at run time.
- added 'additive' information for portal planes. This is no-op at the moment because the flat drawers can't handle additive translucency yet though.
SVN r3149 (trunk)
- updated UDMF spec for player class and skill amount because the old menu limits no longer apply.
- fixed: FloorAndCeiling_LowerRaise needs to consider 4 args in maps to account for the Boom compatibility hack parameter.
SVN r3121 (trunk)
- merged all places where secrets are credited into one common function.
- added the Doom64 COUNTSECRET actor flag.
- fixed: AInventory::CreateCopy did not clear the COUNTITEM flag.
- fixed: Dropping an item did not increase the item count but the dropped item could still have the COUNTITEM flag. Now this flag gets cleared when the item gets picked up so that dropped items don't count a second time.
SVN r2826 (trunk)
the sector. Note that this contrasts with sound sequence things in that it takes a name and
not a number. Also, placing a sound sequence thing in a sector will override this property.
SVN r2492 (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)
they are both created by the first-stage Sigil. AlienSpectre3 should have also been
immune to them but was not. In addition, Macil1 was erroneously immune to V1, when he should
not be immune to any spectral damage. (Though, since he's immortal, all that really amounts to
is that he can enter his pain state.)
SVN r2106 (trunk)
a mild performance increase it's not what I hoped it would do...
- Moved portal initialization for the portal things to P_SpawnSpecials
instead of having the things self-initialize in PostBeginPlay. This was
done to ensure that the portals are fully set up when the game begins.
Otherwise there is no decent way to let the renderer post-process this
information during setup.
- Changed: For 800x600 the default scaling handling of the options menu
makes it become too small so for any resolution with a width between
800 and 959 it has been reverted to the regular clean scaling factor.
SVN r2055 (trunk)
into the FastProjectile base class and removed the native MageWandMissile
class, using the generic functionality instead.
- Fixed: GetReplacement and GetReplacee always checked the skill definitions,
even if they weren't supposed to be used. It was also missing a range check
for 'gameskill'.
SVN r1894 (trunk)
- Added more things from Gez's experimental build:
* MBF grenade and bouncing code.
* Arch Vile ghosts emulation (only for compatibility.txt.)
* Several MBF related compatibility options.
SVN r1821 (trunk)
* 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)
* scalex_top
* scaley_top
* scalex_mid
* scaley_mid
* scalex_bottom
* scalex_bottom
- Added sidedef versions of the linedef flags wrapmidtex and clipmidtex (via
UDMF; names are the same). If the flag is set on the line, it applies to
both sides. Otherwise, each side can control them individually.
SVN r1645 (trunk)
in such a sector. As a workaround for current map formats a new actor
(DoomEdNum 9041) was added that can set the extended sector flags without the
use of ACS and sector tags. The new flag can also be set with Sector_ChangeFlags.
- Fixed: Players ignored MF2_TELESTOMP and always telefragged what was in the way.
- Fixed: Actors with MF5_NOINTERACTION were not affected by the time freezer.
SVN r1315 (trunk)
symbols there instead of into AActor.
- Changed the expression evaluator's floating point precision to double.
- Started rewriting the DECORATE expression evaluator to allow more flexibility.
All the operators use the new functionality but functions, variables and
constants are yet to be redone.
While doing this rewrite I noticed that random2 was always evaluated as const.
This got fixed automatically.
SVN r1264 (trunk)
internal actor classes which no longer exist.
- Changed the state structure so that the Tics value doesn't need to be hacked
into misc1 with SF_BIGTIC anymore.
- Changed sprite processing so that sprite names are converted to indices
during parsing so that an additional postprocessing step is no longer needed.
- Fixed: Sprite names in DECORATE were case sensitive.
- Exported AActor's defaults to DECORATE and removed all code for the
internal property parser which is no longer needed.
SVN r1146 (trunk)
