If the calling code wants to recycle this it will have to pass a container variable to AActor::UnlinkFromWorld and AActor::LinkToWorld.
This was changed because keeping such data in a global variable is dangerous for a set of functions that can be called from a script.
Note that the scripted versions do not yet support saving of the touching_sectorlist.
- Changed the glass shards so that they do not have to override FloorBounceMissile. It was the only place where this was virtually overridden and provided little usefulness.
- made 'out' variables work.
- fixed virtual call handling for HandlePickup.
- made '->' a single token. Although ZScript does not use it, the parser tends to get confused and fatally chokes on leftover arrows so this ensures more robust error handling.
Needless to say, this is simply too volatile and would require constant active maintenance, not to mention a huge amount of work up front to get going.
It also hid a nasty problem with the Destroy method. Due to the way the garbage collector works, Destroy cannot be exposed to scripts as-is. It may be called from scripts but it may not be overridden from scripts because the garbage collector can call this function after all data needed for calling a scripted override has already been destroyed because if that data is also being collected there is no guarantee that proper order of destruction is observed. So for now Destroy is just a normal native method to scripted classes
This bypasses a declaration in the script in favor of a simpler implementation. In order to work it is always necessary to have an offset table to map the variables to, but doing it fully on the native side only requires adding the type to the declaration.
- added support for global variables to the code generator - not the compiler, though. For the handful of entries this is needed for it may just as well be done manually. So far FLevelLocals level is the only one being exported.
- fixed: The VM disassembler truncated 64 bit pointers to 15 digits because the output buffer was too small.
- resolve entire FxSequences instead of aborting on the first failed entry. This allows to output all errors at once.
- Added initial state for "multiplayernext" to prevent possible initialization errors.
- Implemented "mpmap", "mpopen", and "mprecordmap". All 3 commands do exactly as their non-"mp" counterparts do, except they turn on multiplayer (botmode) emulation before doing so.
* 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.
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.
- 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.
- 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.
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 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 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.
Note that even with this change it is still not possible to unarchive any thinker pointers before the thinker list has been loaded as it would create broken lists.
Note that this required splitting P_SerializeWorld, because sector_t and FSectorPortal contain some actor pointers, for which the same rule applies: Portal linking can only be done after all sectors have been read, meaning it cannot be done along with the rest of the data in these structures.
Obviously such a change breaks savegame compatibility so the min. savegame version had to be increased again.
Two issues:
Portal linking requires all skyboxes in the sectors to be present, without them some info is not there when needed.
UpdateWaterLevel was called in AActor::Serialize, which operated on the freshly loaded level where lots of things haven't been set up yet and plane heights may be wrong.
- Converted P_MovePlayer and all associated variables to floating point because this wasn't working well with a mixture between float and fixed.
Like the angle commit this has just been patched up to compile, the bulk of work is yet to be done.
Patched up everything so that it compiles without errors again. This only addresses code related to some compile error. A large portion of the angle code still uses angle_t and converts back and forth.
- First, don't crash when travelling to a map in a hub that doesn't have
any player starts that match the position given to Teleport_NewMap (or
equivalent).
- Seconed, move the player to the location they were at when the left the
level. At least that way, they shouldn't be in random geometry or off
the map entirely.
This was to resolve some circular dependencies with the portal code.
The most notable changees:
* FTextureID was moved from textures.h to doomtype.h because it is frequently needed in files that don't want to do anything with actual textures.
* split off the parts from p_maputl into a separate header.
* consolidated all blockmap related data into p_blockmap.h
* split off the polyobject parts into po_man.h
Note about A_SkelMissile: The direct change of the missile's position was changed to use SetOrigin. If this is later supposed to be portal-aware, such direct coordinate changes are a no-go to ensure that everything is properly maintained.
'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.
- Viewheight change was delayed: Viewheight must be copied to player
structure as well as the PlayerPawn. Not sure if should actually use
deltaviewheight to spread the change out over a few tics instead of
being instant.
- Viewheight not preserved when travelling: player->viewheight must be
restored from pawn->ViewHeight, because the temporary player set it back
to the default viewheight.
- Move MUSINFO change request out of FLevelLocals and into player_t. This
allows the MusicChanger actors to change music for each player
independantly. This is similar to PrBoom+, which switches depending on
the displayplayer. The difference being, we don't actually track the
music other players are listening to. (Which might not be a bad idea to
implement at some point.)
- Moved a few fields in player_t for better packing.
