Originally, we store the search results in a CMemory instance which we then assign to the actual function pointer. CMemory is just a pointer class; we can assign the results directly to the actual function pointer. This commit reduces a lot of code verbosity, and also reduced roughly 2KiB worth of static pointers in the resulting executable. This commit also officially deprecates the support for any GameDLL's below S3 (Season 3), since it makes more sense to port the assets from earlier/later games back to the version this SDK supports.
Utilize the new IDetour::DetourSetup() code, IDetour::Attach and IDetour::Detach have been removed in favor of this (significantly reduces chance of user error). Since the template check happens in the idetour header, it is much more aggressive on type mismatches, such as a difference in parameter types, between the function and detour, will now raise a compile time error. As a result, some type mismatches have been fixed in this commit as well.
Find regex pattern:
inline auto ([a-zA-Z0-9_]+) = ([a-zA-Z0-9_]+)\.RCast<([a-zA-Z0-9_:<>*]+) *\(\*\)\(([^)]*)\)>\(\);
Replace regex pattern:
inline $3(*$1)($4);
This commit also removes the unnecessary initialization (which was required to type the auto variables),
and therefore removed 6kb of unnecessary dynamic initialization code.
Force inlining this was a temporary solution in the past to overcome a crash caused by stack corruption. This problem seems to be solved, and thus its no longer necessary to force inline all methods.
Mapped out all members, also fixed the initialization of members. Some fields were never getting initialized, and m_iCurrentState was initialized improperly.
This change was planned for a long time. This moves all REGISTER calls to a single translation unit, this is required as we currently added a very dirty workaround for not registering duplicates by checking if VFTable pointer was already present in the vector... Registering from single translation unit prevents duplicate instances that gets created if header is included by more cpp files.
Reworking this reduced 100kb+ of compiled code. This commit also reworked the way functions/variables/constant gets logged with their addresses; the new code formats them on the fly, and allows for resize at any time. Formatting is no longer required by programmer.
TODO: currently there are some compile errors for dedicated and client dll's. These will be resolved very soon as they need to be properly worked out still (server & client only stuff needs to be properly split). Use the 'main' (stable) branch for the time being if you need to compile these dll's.
Bool is a char on this platform, and UINT8_MAX is 0xff (255), yet we set this char to 256 causing arithmetic overflow. Looking at the assembly of the game, this really is a uint16_t, and gets set to 256 in CHostState::Init, parsed to State_NewGame as 256 before the lowbyte is being reset to 0.
SourceSDK mathlib port with light modifications.
Renamed Vector to Vector3D (to avoid confusion with std::vector (declared as vector) and Vector2D/Vector4D).
* Mostly rebuild CServer structure.
* Partially rebuild CNetworkStringTable structure.
* Partially rebuild CNetworkStringTableContainer structure.
* Removed redundant patterns which are now covered in the data structure.
This is currently the most robust way to perform this.
However it might fail still as the locks don't seem valid for the second loads (we currently load more paks from the same queue..).
We need to push the strings to the queue list and let the engine load these too so a new lock is acquired for that job.
Note: this does not work reliably still.
The only way we could make this work 100% reliable would be to fully rebuild '0x140341D40' in the SDK and load our pak files among with the pre-existing g_pakLoadApi->AsyncLoad() call in this function, as this will ensure everything will be ran synchronously.
The current approach by taking some JT fifolock wrapper will only work reliably between one level change, unsure why the second and up fail.
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)
* Dedicated SDK now supports ASLR enabled executables.
* Complete removal of CEngineClient on the dedicated server.
* Complete removal of gHLClient and g_pHLClient on the dedicated server.
* Performance improvements for the dedicated server frame loop.
* ConVar 'CVCallback_t' structure rebuild.
* Reduced overhead throughout SDK.
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).
Game will check scripts/levels/mapname.json and load all rpaks in the rpak field.
Game now also unloads pak files loaded by the SDK preventing crashes and unnecessary memory usage.
VPK's and STBSP's are planned to be added as well.
* Add CServerGameDLL interface to SDK (unfinished)
* Inline all CHostState members. Calling discrete member functions will result in a corrupt stack. It also alters with the VTable layout in the engine since we assign our SDK instance directly to it. Forcing everything to be inline (like the assembled counterpart within the executable itself) will ensure no virtual calls will get created and misalign the base VTable.
* Patch SQVM_CompileError to call SQVM_Error with the severity flag set to false (0 = do not terminate process, 1 is terminate process).
* Add Cbuf_AddText and Cbuf_Execute signatures.
* Remove additional VGui stuff from dedicated statemachine.
* Move signatures to their respective headers.
* De-inline 'CHostState::FrameUpdate()'
* Ported al new patters to GAMEDLL_S1, CEngine still recreation needs extra work
* Codebase restructured to SourceSDK codebase style and .cpp/.h assertion paths in the game executable.
* Document most functions with valve style 'Purpose' blocks.
* Rename variables to match the rest of the codebase and Valve's naming convention.
* Dedicated DLL and the SDKLauncher now share the same codebase as the DevSDK.
* Obtain globals or pointers directly instead of waiting for runtime initialized data.
* Dynamically search for all functions and globals (this doesn't count for dedicated yet!).
* Initialize most in-SDK variables.
* Move certain prints and other utilities under ConVars to reduce verbosity and increase performance.
* Print all pattern scan results through a virtual function to make it easier to add and debug new patterns in the future.
* Type global var pointers appropriately if class or type is known and implemented.
* Forward declare 'CClient' class to avoid having 2 'g_pClient' copies.
* Add IDA's pseudo definitions for easier prototyping with decompiled assembly code.
* RPAK decompress Command callback implementation.
* Load decompressed RPaks from 'paks\Win32\' overriding the ones in 'paks\Win64\' (the decompress callback will automatically fix the header and write it to 'paks\Win32\').
* VPK decompress Command callback implementation.
* Move CRC32 ands Adler32 to implementation files.
* Server will print out more details about the connecting client.
* Upgrade ImGui lib to v1.86.
* Don't compile id3dx.h for dedicated.
* Don't compile id3dx.cpp for dedicated
* Implement DevMsg print function allowing to print information to the in-game VGUI/RUI console overlay, ImGui console overlay and the external windows console
* Fixed bug where the Error function would not properly terminate the process when an error is called. This caused access violations for critical/non-recoverable errors.
* Fixed bug where the game would crash if the console or server browser was enabled while the game was still starting up.
* Several bug fixes for the dedicated server (warning: dedicated is still considered work-in-progress!).
