This reverts commit 81449728d7.
Reverted because it compromises the IWAD file lookup and fixing it properly is not so trivial.
The skipping of adding the file name extension was not only broken, but even after fixing the code does not work if the IWADs are located outside the working directory.
This fixes an issue with DUMP 2 which looked for patches of the same name as the texture currently being defined and where the patches had the same use type as the composite texture. The function as implemented would only find the newly added composite and print an error.
- fixed: Script functions did not receive the function name when being created.
- relaxed the asserts for PARAM_STATE, because the VM knows nothing about ATAG_STATE. Any state variable's content (e.g. Actor.SeeState) will receive ATAG_GENERIC, rather than ATAG_STATE.
- added a 'NeedResult' flag so that certain operations can create shorter code if the result of the expression is not needed. So far only used for postdecrement/increment statements on local variables (which is the most frequent case where this matters.)
- fixed postincrement and decrement for local variables. Due to the result preservation semantics it created faulty code.
If done earlier they will not be able to detect overrides of sprites and graphics which are not part of the PATCHES lump. There was some fudging code to work around this problem but it was only partially working.
Now these textures only collect the texture name and use type during setup and resolve them after all textures have been created.
This was probably responsible for some weird behavior recently, but with the addition of the OF_Transient flag this outright crashed because it left NULL pointers on reload in places where they weren't checked for.
- synthesize PField entries from the flag list for AActor. This intentionally excludes the bounce flags for now.
- allow deprecated flags that do not call the deprecated flag handler.
- disallow constructs like (a = b) = c by not allowing an address request on an assignment operation.
- restrict modify/assign on boolean variables to the bit operators. Everything else needs to promote the result to an integer to make sense so it should be disallowed.
- removed 'self' as a dedicated token. Internally this gets handled as a normal but implicitly named variable so the token just gets in the way of proper processing.
- removed P_ prefix from SpawnMissile export.
- fixed a crash with misnamed function exports.
- added the above for the 'if' condition. It works for integers, floats and pointers and will save 3 instructions if the condition is a non-boolean that can be implicitly casted to bool.
- allow class extensions.
These are separate blocks in different files that get concatenated to one class body for processing. The reason is to allow spreading the many functions in Actor over multiple files, so that they remain manageable. For example, all the Doom action functions should be in their respective files, but their symbols need to be in Actor. To extend a class, both files need to be in the same translation unit, so it won't allow user-side extension of internal classes.
- added a TESTN instruction. This is like TEST but negates the operand. This was added to avoid flooding the constant table with too many case labels. With TEST and TESTN combined, all numbers between -65535 and 65535 can be kept entirely inside the instruction. Numbers outside this range still use a BEQ instruction.
- This was only visible when using a screen wipe because the initial frame wiped
to would clamp the pitch to whatever undefined pitch range the player
had before the proper range was received.
- Instead of calculating lighting based from the left edge of the wall
segment the decal was on, it was calculated from the left edge of the
wall instead.
- 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.
- fixed emission of the self pointer in FxVMFunctionCall. I did not realize that the self expression only sets up a register for the value, not pushing it onto the stack.
This will restrict them to the only classes that may use them: Weapon and CustomInventory.
Note: Should a mod surface which uses them improperly the better solution would be a warning message and NULLing the bogus code pointer instead of leaving them in Inventory.
Ironically this only requires a very minor change in the calling code and an added member for the VMFunction to tell that code how many parameters to pass.
This change will allow to turn the vast majority of action functions into regular members, the only ones that still need to be an action function are the few that actually use the pointers.
This is not testable right now because finally the action function mess has come full circle. The current setup makes it impossible to call action functions from non-action functions because the needed info is local to the functions.
Long avoided, this needs to be refactored now so that the different semantics for action functions are no longer needed.
- VC++ generated horribly stupid code for x64 when incrementing pc at the
beginning of each instruction by storing hundreds of copies of it for
every opcode executed. Incrementing pc at the end avoids this madness.
- It is possible I messed something up with this change. Hopefully not.
- fixed: FxMemberIdentifier checked for ClassPointers instead of object pointers to resolve the left hand side of the expression.
- allow comparison of pointers.
This also means that for now Lua-style multi-assignments are disabled, those should be easy to enable by making some changes to the assignment_statement grammar so that it doesn't recognize single assignments, but for now this is low priority because it adds a significant amount of complexity to do this right with functions that have multiple return values.
The generated object code can definitely use an optimization pass but that's something left for later when more things are working. Right now it creates one opcode more than necessary for all member accesses (instead of using the offset in the store command it calculates an actual address of the variable in another address register) and can create one too many for non-constant expressions being assigned to local variables (a move between two registers because the emitted expression on the right hand side does not know that it can emit to the actual variable's register.)
- create proper variable data from the function prototype instead of assuming that there's just 3 pointers.
- added a printable name to VMScriptFunction for error output during gameplay in case something goes wrong.
All break and continue statements were collected in one list, and each loop statement taking hold of that entire list, including the breaks and continues from previous outer loops.
Changed it so that loop statements contain the jump addresses themselves and set a pointer in FCompileContext, so that the jump point can be set directly in the loop statement - and an error printed if there is none in the resolving stage, not the emitting one.
Consolidated the identical backpatching code of the three loop statement nodes into a subfunction.
- disable generation of the parser's trace file in debug builds.
This increases parsing time by a factor of 15 and is only needed when debugging a problem in the grammar.
- handle all binary operators which are already implemented in the code generator.
- implemented sizeof/alignof operators in code generator.
- rewrote RequestAddress so that its return value is not the writability of an address but the mere existence. Also changed it to not output errors itself because those cannot be dealt with by the calling function.
- added the '>>>' (unsigned shift) operator. Although, with unsigned numbers available, this is technically not really needed, DECORATE supports this so ZScript should, too, if only for the benefit of making conversion tools easier to handle.
- fixed: FxBinary::ResolveLR' check for numeric operations was incomplete. Like far too many other places it just assumed that everything with ValueType->GetRegType() == REGT_INT is a numeric type, but for names this is not the case.
These were previously faked with the inverse plus a boolean not. Although this works, it either leads to sub-optimal code generation or some fudging to avoid the inefficient handling.
Just adding proper handling to the parser seems the easiest and most straightforward way to get around this. The code generator already can deal with these operations properly so there's no good reason to do it differently.
- added a descriptive name to all types for error messages.
- added a generic type cast node to the code generator.
- added a few more cast operations to the 'cast' VM instruction.
- extended FxClassTypeCast to handle all possible input that can be cast to a class pointer, not just names.
ZDoom only uses these types in a very few isolated places, and even those can be removed without problems, so it's very doubtful that having support for these types is of any benefit - on the other hand, having them will most likely introduce more code than is saved in the data by using them...
- implemented handling of the basic math operators so that heretic/beast.txt can be processed.
This is working, aside from still needing the type casts to properly transform the strings to class pointers.
- ANIMATED contained definitions for Doom, Heretic, and Strife, all
crammed into a single file. This meant that animations from one game
could erroneously make their way into maps for another game that
provided custom textures with names that matched textures that animated
in the other game. There are now three separate ANIMATED lumps with only
the animations defined for the original game and no others. The one
that gets loaded depends on the game being played.
- Added documentation for the ANIMATED file format to the comment for
FTextureManager::InitAnimated(), since I had to figure it out from the
code.
- Setting an actor's Crash state has the potential to destroy the actor if
the Crash state has one or more 0-tic states that end with Stop. This
was not taken into account when the object's Z velocity was 0, but it
was under the floor anyway.
For the random functions this class only handles the default-RNG version. The one with an explicit RNG needs to be done separately because the parser produces different output for them.
- added a truncation warning to FxIntCast, which only occurs with ZScript, not with DECORATE. FxBoolCast is intentionally left out because it would defeat the reason for this cast type.
- removed Self parameter from FxFunctionCall. Actual member function calls through an object require quite different handling so lumping these two together makes no sense.
- added a workaround to deal with ACS_NamedExecuteWithResult to both the compiler and FindClassMemberFunction. The way the ZScript compiler sets this up means that it will call the builtin, not the actual action function, so the parser needs to do some explicit check to get past the same-named action function.
- pass a proper self pointer to FxActionSpecial. Although it's still not being used, propagating design shortcuts through several function levels is a very, very bad idea.
* explicitly require passing the owning class when creating it.
* extract self pointer class when adding a variant.
* put the flags on the single variants, we can not fully rule out that they will be 100% identical, if variants ever get allowed.
* 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.
- 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.
It looks like the setup of the action function and the adding of the states got inverted by something I tried, leaving the ActionFunc member empty on the real states.
- fixed a few problems that were encountered during conversion:
* action specials as action functions were not recognized by the parser.
* Player.StartItem could not be parsed.
* disabled the naming hack for PowerupType. ZScript, unlike DECORATE will never prepend 'Power' to the power's name, it always needs to specified by its full name.
* states and defaults were not checked for empty bodies.
* the scope qualifier for goto labels was not properly converted to a string, because it is an ENamedName, not an FName.
- Every update rolled into one, because I'm pretty sure I missed some while
updating lemon.c (not counting today's commits), since it wasn't always
updated at the same time as lemon.c.
- In particular, I think this check-in from 2016-06-06 was very important to
us after commit 3d5867d29e (For the
Lemon-generated parser, add a new action type SHIFTREDUCE and use it to
further compress the parser tables and improve parser performance.):
* Fix lempar.c so that the shift-reduce optimization works for error
processing.
- started with the AST converter. So far it only deals with direct function calls with simple constants as parameters.
- added an error condition for the defaults block to get rid of some asserts.
- fixed uninitialized counter variable in DECORATE parser.
- allow dottable_id of xxx.color so that the property parser can parse 'powerup.color'.
- fixed crash with actor replacement in script compiler.
- add the lump number to tree nodes because parts of the property parser need that to make decisions.
- removed test stuff.
- converted inventory.txt, player.txt and specialspot.txt to ZSCRIPT. These were the minimal files required to allow actor.txt to parse successfully.
- removed the converted files from the DECORATE include list so that these are entirely handled by ZSCRIPT now.
- split FinishActor into several functions. While DECORATE can, ZSCRIPT cannot do all this in one go.
- split the state finalization into several class-specific virtual functions.
* 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.
To do the rest, some cleanup is needed first, to untangle the DECORATE parser from the actual code generation so that the low end stuff can actually be reused here instead of having to be redone.
Ultimately, thingdef should only contain code that is directly related to the DECORATE parser, but that's not the case with this file. It's only function definitions which get used during gameplay and will also be accessed by ZScript.
The change is intentionally on master so that pull requests can adjust to it now instead of creating conflicts later.
* Goto did not support the class scope operator '::'. Like in DECORATE, this cannot be done with a simple '.' because it creates semantic problems with first part of a state label. This requires different syntax so that it can unambiguously distinguish between a scope identifier and the actual label
* Goto used the incorrect token PLUS for '+' instead of ADD.
* The state's duration was not stored in the AST.
* Truncating the sprite name inside the parser is probably not the best idea because it used a simple Printf to report this. Let's do this during processing of the AST where this can be properly handled as an error.
- Sets the absolute amount of an inventory actor.
- Limits itself to the range [0, MaxAmount]. Setting beyondMax to true disregards the MaxAmount. Default is false.
- 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.
This adds:
* builtin types color, state and sound.
* ending a parameter list with an ellipsis to declare a varargs list. (A_Jump uses this.)
* allowing to declare optional arguments by giving them a default value.
* adding an 'action' qualifier for function declarations.
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.
This had been defined as a regular compound statement but in the context this will be used in, that makes very little sense, because all it can do is set some constant values.
The most important thing here is that it doesn't provide an unnecessary learning curve to its users and doing it this way will not only ensure that but also avoid redundant documentation.
To allow initialization of other user-defined properties it will require some extensions but that's a job for later and can just as easily be done in the current framework, rather than throwing everything out and start from zero.
- added checks for duplicate field names.
- moved the tree node symbol tables out of PSymbolTreeNode to the worker data. That symbol is a bad location because it restricts the usefulness of the symbol class which is also needed for variables which use different AST structs.
- fixed some memory management issues with the work classes for the compiler that became apparent after moving the symbol tables in there. In several places these were copied around, possibly losing data.
- fixed: The tree nodes for classes and struct members were stored in the global tree nodes table.
- sort variable declarations into their own list for processing.
This uses a different algorithm as the old implementation - instead of recursively resolving unknown symbols it will first collect all constants from all scopes and then process them in one operation, doing multiple passes over the list until no more constants can be resolved anymore.
- fixed class creation. There was an infinite loop and some missing checks for native classes.
- do not write the compiler's symbols to the same symbol table as the output. The output must go to GlobalSymbols but the internal symbols must go to a namespace specific table that can be discarded after compilation.
This is the first thing the compiler has to do to get access to the class's symbol table. Of course at this point the final size of a class is not known yet so these are currently all treated as tentative.
- place generated symbols into GlobalSymbols instead of a scratch table that will be discarded right away.
- allow the state object to change source file scanners (I hope this works, but the old implementation was unable to do more than one with with a parse state so I had to change it.)
- It can now parse constants.txt and insert everything in it into the global symbol table and make subsequent DECORATE compile properly.
Instead of replacing the original, the second class will get renamed now, using the originating file as an identifier. In the vast majority of cases this should do exactly what is needed: Create an unconflicting second class that can coexist with the original. Unless the class is used by name this should eliminate all problems with this, but so far I haven't seen anything that used them by name.
This is choosing the lesser of two evils. While some mod out there may get broken, the old setup meant that the first class of a given name could not be written out to a savegame because it was not retrievable when loading it back.
Ultimately we may have to get a fully qualified name out of this, so Outer should be a type that can handle this feature. The new class for this is currently used as base for PType and PSymbol so that PNamedType inherits from it and maybe later a namespace symbol can, too.
There have been reports about crashes in here with Linux that point to some of the code that gets called here doing unwanted things on the owner, so with these links cleared that should no longer be possible.
- This was fine with fixed point numbers, since they could never be
outside of short range when converted to regular ints. With floating
point numbers now, that condition no longer holds.
As was pointed out: "That said, there is one minor problem - different game artstyles can constitute whether Bloom is turned on, which tonemap is used, etc. For example, when playing Doom, I like having my bloom on, but if I am going to start playing the Adventures of Square, the art style and bloom don't mix, in my opinion. For this, I have to remember to switch my bloom settings every time I switch IWad"
- allow recursive linking of $random definitions (as long as they do not link back, see above.)
- fixed the sound precaching which did not handle $alias inside $random. Normally this went undetected but in cases where the random sound index was the same as a sound index in the current link chain this could hang the function.
- check and use WGL_EXT_swap_control_tear extension. The above change makes the system always wait for a full vsync with a wglSwapInterval of 1, so it now uses the official extension that enables adaptive vsync. Hopefully this also works on the cards where the old setup did not.
The slot had been there forever to address this same problem but only one of the two constructors actually set it, too bad that it was the wrong one...
This is something that normally won't be noticed. But if some actor is spawned on a moving platform, with both thinkers on the same statnum it means that the order of execution is not correct with the platform being done first, resulting in the actor to 'jump' while the platform is moving. To prevent this it is necessary that all sector movers only tick after all actors have completed their thinking turn.
We have to be extremely careful with the player data, because there's just too much code littered around that has certain expectations about what needs to be present and what not.
Obviously, when travelling in a hub, the player_t should be retained from the previous level. But we still have to set player_t::mo to the PlayerPawn from the savegame so that G_UnsnapshotLevel doesn't prematurely delete it and all associated voodoo dolls, because it checks player_t::mo to decide whether a player is valid or not.
The actual deletion of this redundant PlayerPawn should only be done in G_FinishTravel, after the actual player has been fully set up
* do not skip the player_t init when travelling in a hub. The old player may still be needed in some edge cases. This applies only to singleplayer for now. The multiplayer version still needs reviewing. I left it alone because it may shuffle players around which is not wanted when doing hub travelling.
* do not spawn two temp players in G_FinishTravel. Instead handle the case where no player_t::mo can be found gracefully by adding a few nullptr checks. This temp player served no real purpose except for having a valid pointer. The actual start position was retrieved from somewhere else.
- Fixed properties not having the proper indices.
- Use ViewPos-to-actor instead of measuring actor-to-actor.
- Use the actual camera instead of the actor so camera textures can work.
I wish I had realized this the last time it came up - it would have saved me a lot of trouble.
But as it turns out, the more recent travelling code makes all of this completely unnecessary, working perfectly fine with deleting the player pawns along with the rest of the thinkers before loading the stored ones from the savegame (and getting rid of those in G_FinishTravel.)
And with a sane savegame format that does not depend on side effects from how the thinker serializing handled linking into the lists the old code was even harmful, leaving voodoo dolls behind.
I had the exact same effect when I tried to reshuffle some things for reliably restoring portals, but did not make the connection to interference between two mutually incompatible player travelling mechanisms that just worked by sheer happenstance with the original order of things.
- changed S_GetMusic to return a const pointer to the actual music name instead of a copy. The only thing this is used for is the savegame code and it has no use for a copy, it can work far more efficiently with a const pointer.
After testing with a savegame on ZDCMP2 which is probably the largest map in existence, timing both methods resulted in a speed difference of less than 40 ms (70 vs 110 ms for reading all sectory, linedefs, sidedefs and objects).
This compares to an overall restoration time, including reloading the level, precaching all textures and setting everything up, of approx. 1.2 s, meaning an increase of 3% of the entire reloading time.
That's simply not worth all the negative side effects that may happen with a method that highly depends on proper code construction.
On the other hand, using random access means that a savegame version change is only needed now when the semantics of a field change, but not if some get added or deleted.
- do not I_Error out in the serializer unless caused by a programming error.
It is better to let the serializer finish, collect all the errors and I_Error out when the game is known to be in a stable enough state to allow unwinding.
It turned out this may not be done automatically when opening the savegame - it has to be done later, after the pre-spawned map thinkers and all connected objects have been destroyed.
The object deserializer also has to be rather careful about dealing with parse errors, because if something goes wrong a whole batch of uninitialized or partially initialized objects will be left behind to destroy.
This means that no object class may assume that anything but the default constructor has been run on it and needs to check any variable it may reference.
- always make the top level object randomaccess when opening a JSON file for reading. Some things won't work right if this is opened for sequential access.
- Several mods were able to just take advantage of A_SetRipperLevel and the likes, essentially bypassing this gate so there really is no point in doing this anymore.
This is so that PNGs can be written to memory, not just to an external file. stdio's FILE cannot be easily redirected but a C++ class can.
The writer is very simple and primitive right now, allowing no seeking, but for the job at hand it is sufficient.
Note that large parts of savegame creation have been disabled, because they are about to be rewritten and it makes no sense to adjust them all before.
- converted sound and canvas texture serialization.
- refactored file_zip, so that it can be used to load loose zip files and extract their compressed data directly.
- added handling to FSerializer to generate and consume compressed Zip file entries.
If all goes well this will allow saving savegames as Zips when the rework is done, which will make analyzing them a lot easier.
- fixed a few errors in the ACS module serializer.
- reordered a few things to how they were in the old code.
- optimized serialization of the level.Scrolls array to happen within the sector. This is to allow skipping 0-entries which normally constitute the vast majority of them.
- added sanity checks to prevent a savegame from being loaded with an incompatible map
- refactored a few things to simplify serialization.
- started work on main level serializer function.
The way this was done was a major headache inducer, requiring reconstruction of the function each time the value was changed and in general made actor damage a major hassle.
There was a DECORATE wrapper to mimic the original behavior but this looked quite broken because it completely ignored the different semantics of both damage calculation types.
It also made it impossible to determine if damage was a function or a value.
This accessor has been reverted to what it should be, only returning the constant, which now is -1 for a damage function. I am sorry if this may break the odd mod out but a quick look over some DECORATE-heavy stuff showed that this was never combined in any of them so that accessing 'damage' in DECORATE code depended on an actual damage function.
To get proper damage, a future commit will add a DECORATE function which calls AActor::GetMissileDamage.
actorlist, actornum, monsternum, itemsnum, countitemsnum
Modified the following ccmds:
monster, items, countitems
All commands with "num" at the end simply print a count of their respective filters, all other listed commands now print a list and a count.
This was done to clean up the license and to ensure that any commercial fork of the engine has to obey the far stricter requirements concerning source distribution. The old license was compatible with GPLv2 whereas combining GPLv2 and LGPLv3 force a license upgrade to GPLv3. The license of code that originates from ZDoomGL has not been changed.
TabCommands use an FName to store the command's name so once the NameManager is destroyed its data will become invalid.
This is a problem because C_RemoveTabCommand is being called from FBaseCVar's destructor and most CVARs are global variables.
- Trails now copy pitch, and set the projectile as the target.
- Added GETOWNER flag. Using it sets the owner of the fast projectile as the target instead, if it has an owner.
int SetActorFlag(int tid, str flagname, bool value);
- Mimics DECORATE's A_ChangeFlag
- Returns number of actors affected (number of things with the flag)
- Affects activator if TID is 0
# Conflicts:
# src/p_acs.cpp
It could only work with right to left function argument processing, but with left to right it failed because the ParseExpressionA call altered sc.TokenType.
Note that with register-based arguments on 64 bit platforms this is a very critical issue!
As with the Stereo3D stuff, this cannot be done because recursive processing of portals will change it. Instead the local copy has to be used here, just like the EndDrawScene call already did.
- disable framebuffers for camera textures in legacy mode entirely. This depends on a GL_DEPTH24_STENCIL8 surface which most of these old chipsets do not support, and I really see no point to invest any work here. The worst that can happen is that oversized camera textures won't be processed, which, due to general performance issues, might even be a good thing.
Both of these were inherited from ZDoomGL and in terms of light design in maps it makes absolutely no sense to have them user configurable. They should have been removed 11 years ago.
- restricted gl_lights_additive to legacy code and removed menu entry for this.
For modern hardware this setting is completely pointless, it offers no advantage and degrades visual quality. Its only reason for existence was that drawing additive lights with textures is a lot faster, and that's all it's being used for now.
The fixed point version had a mostly useless check that excluded ANGLE_MAX, this got incorrectly converted to floating point.
Note that this version will clamp the angle to 360°, not merely overflow like it did with the fixed point code
2D calls are accumulated and then executed all at once at the end of the frame, but this one needs to be interleaved with the 3D rendering. It now uses the quad drawer to fill the portal with blackness.
The reason for this is that the macOS version uses a deprecated API and in order to correct this, the file needs to be compiled as Objective-C++ which requires a different extension.
It acts as a simple wrapper around P_DamageMobj which can damage a
single actor, but can also set the actor inflicting the damage. It
returns the amount of damage actually done, or -1 if the damaging was
cancelled.
- Crashes occurred if a particular actor was a tracer to the player and the actor was not gone by the time the player unmorphs.
- Failed unmorphs occur if tracer was manipulated through means like A_RearrangePointers, etc.
- added colormap shader to postprocessing.
This replaces the in-place application of fullscreen colormaps if renderbuffers are active. This way the fully composed scene gets inverted, not each element on its own which is highly problematic for additively blended things.
After doing some profiling it was very obvious that this has better performance than client arrays. Persistent buffers are still better, though, especially for handling dynamic lights.
- Use with FMOD Studio 1.06.x. 1.07 and 1.08 compile but for some reason produce a lot of noise on vanilla Doom sounds.
- Crashes when used with fluidsynth provided by Ubuntu 16.04, but a self compiled version of the library works just fine.
- Reverbs are mostly untested, but implemented.
- Debug waveform drawing is not implemented as it requires a non-trivial amount of work.
- It will still show as FMOD Ex in the menus since I'm too lazy at the moment to make it a "separate" backend.
Since this list is excluded from regular thinker cleaning, anything that may survive through the end of G_FinishTravel will endlessly multiply and severely break the following savegames or just simply crash on broken pointers.
This is slower than doing it in the render pass so it's only active when actually needed - it's also slower than using a client array so this code only gets used when there is no choice but to work with a 3.x core profile context.
This reverts commit 5ff0abe568.
- use STAT_INVENTORY only for held items.
Seems this was causing some strange issues with hubs, but for items placed in the world it still cannot be allowed to have them in a different statnum.
This addresses a very strange crash I encounteded while travelling in a hub, and ended up with a NULL pointer after the 'Serialize' call which means that some code cleared the variable that is currently being deserialized. I was completely unable to find out what caused this because there is so much recursion going on in the deserializer. All actions on the deserialized actor are now being done with a local copy of that variable so that altering the actual one won't have any adverse effects.
bool CheckActorState(int tid, str statename, bool exact = false);
- Same parameter order as SetActorState
- Returns true if actor has the state; else returns false
This was causing issues with sprite sorting. For this to work as intended, all actors in the world that display sprites need to remain in spawn order, including inventory items.
The only thing this statnum was used for were some bot related search actions which are simply not worth breaking actual maps for some very minor performance gain.
Now Scroll_Texture_Model is working properly again. (Note: Whoever designed this function must have been on drugs - its use of the source data in Boom is completely insane.)
This fix is still incomplete, it should really discard everything outside the polyobject, not outside its bounding box, but at least it eliminates the most severe occurences of dislocated items.
That's again one less write access to the buffer. The uniform method was chosen because this way a buffer update can be completely avoided, and setting a single uniform is a lot cheaper and simpler to handle.
- only disable clip planes on Windows, but not on Linux or macOS.
- If a driver reports full OpenGL 4.5 support, assume that all features are working properly.
So something like 'return ++user_x;' is now possible
Admittedly this needed quite a bit of refactoring mainly due to the fact that return types now have to be checked after resolving the function rather than before
This eliminates most behavioral differences for FFlatVertexBuffer between both operating modes, now the only difference is where the buffer is located.
