'MemAllocSingleton()->Free()' does not call the object's destructor. Ideally we override the default memalloc system with that of the engine, but unlike other Valve Source games, Apex Legends is monolithic and does not export 'MemAllocSingleton()' from tier0. We could manually patch the executable to 'export' this, might need a code cave as this function got inlined practically everywhere.., but even then, this results in a circular import as we import the gamesdk from the exe, which might just work, but Windows 7 is usually a lot less tolerant in approaches like these.
We should explore this in the future.
Relies on the engine's implementation of 'KeyValues::RecursiveSaveToFile'. The IFileSystem methods have been fixed up with the CUtlBuffer class rebuild in which we could call these to write a KV memory structure as a file to the disk.
* Fix all compiler error for GameSDK on S0 and S1.
* Remove some unused patterns and globals (launch performance gains of 100ms).
* Remove most duplicate patterns.
* Relocate globals from engine to a more appropriate location.
* Renamed some unknown vars to a more appropriate name (most of these where obtained a while back, but as we reversed more parts of the engine, some of these vars become known).
* Renamed some vars to fit the naming convention used in the SDK.
* Fixed pattern debug logging using the wrong pointer, thus displaying the wrong address.
* Removed some unused signatures.
* Named 2 CBaseFileSystem methods, and applied them to 'MOD_ProcessPakQueue()'.
* Renamed 'qword_1671061C8' to 'g_pMTVFTaskItem'.
* Renamed 'g_pMapVPKCache' to 'g_szMTVFItemName'.
* Only set first byte to 0 in 'g_szMTVFItemName' (actual size is 0x100, not 0x40).
Implement VFTable's to interface with engine (for the most part mapped out, only the new VPK methods needs further reversing).
This exposes a good majority of the FileSystem implementation of the engine, to the SDK.
Class has been mostly copied from the Valve SourceSDK.
Modified to fit this particular engine.
Modifications include:
* More consistent naming.
* Using c++ style casts over c style casts.
* Using c++ datatypes for assigning default.
- nullptr and size_t for pointers and size types.
* Added vftable interface for 'IFileSystem::RemoveSearchPath'.
* Added hook for 'CBaseFileSystem::AddSearchPath'.
* Added hook for 'CBaseFileSystem::RemoveSearchPath'.
* Added method in KeyValues for loading a KV file and parsing it via the game exe (loads from cache, vpk and disk).
* Added method in KeyValues to parse GameInfo.txt when the engine loads this.
* Added new function 'GetAvailablePlaylists' to all VM's.
* Moved function 'GetAvailableMaps' from UI VM to all VM's.
* Improved logic behind 'GetAvailableMaps'.
* Server browser and SQVM now rely on 'MOD_GetAllInstalledMaps'. This new function populates the global vector 'g_vAllMaps' with all installed maps.
* Improved 'KeyValues' structure to use union for shared members.
Moved every pattern to IDetour interface. This allows for debugging patterns scans more easily, and create threads during pattern searching (Operation is now fired in APIENTRY).
Also cleaned up some unused code/extraneous comments.
Slightly increased performance by purging duplicate patterns.
Made variable search less dependent from other results (except if pattern-to-scan results is within the same header)
Migrating to this to initialize all patterns and prototypes in Systems_Init() instead.
This should make debugging missing/not found patterns easier and allow for opting out variable/constant search (some of these require other patterns to be found, thus resulting in seg faults..).
Also added check to detect if user has a eligible CPU to run this SDK.
The game requires SSE and SSE2 instruction sets. Our SDK requires this too due to the use of SSE intrinsics, so we cannot let the game handle this. We have to check it ourselves.
* Move most definitions to implementation file to avoid recompiling whole program for small changes
* Pass strings by reference for where possible.
* Split Module class to dedicated file.
* Add const qualifiers to all eligible methods for address/module class
* Some renaming
Inline every signature defined in the SDK (previously each translation unit had its own copy of the signature and function prototype). DLL init is near instant now (85% speed improvements).
* Added 2 new FileSystem pointers with new features in their classes.
* Register all factory instances created by the GameDLL in the SDK.
* Added new command 'fs_mount_vpk' to mount a specified VPK file.
* Renamed 'fs_decompress_pak' to 'fs_unpack_vpk'.
* Some renaming of Factory and VPK types.
* Some light optimizations/cleanup.
* Rebuild CModGroupApp::Main, did not include the dedicated routine with the empty class global.
* Using a template function now for virtual function calls
* Implemented most of the CEngine class and grabbing its global var now.
* Using local CEngine now in FrameUpdate
* Implemented EngineParms_t fully and grabbing its global var.
* Added macro for adding class member variables at offsets.
A lot of comments added regarding what needs to be done for this commit.
* Check other season compability, wasn't able to do that due to not having access to said binaries at the moment.
* Fix sdklauncher to use widestrings to fix the bug with other languages in path
