* _opcodes.cpp
*-----------------------------------------------------------------------------*/
Code base refactor + major performance and readability improvement. Read description for details. * 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!).

Light project restructure Moved server/client headers and implementations into dedicated subfolder. Renamed Some classes to match the game binary (e.g. CBaseClient is now CClient). Removed redundant files.

Initial port to CMake * All libraries have been isolated from each other, and build into separate artifacts. * Project has been restructured to support isolating libraries. * CCrashHandler now calls a callback on crash (setup from core/dllmain.cpp, this can be setup in any way for any project. This callback is getting called when the apllication crashes. Useful for flushing buffers before closing handles to logging files for example). * Tier0 'CoreMsgV' function now calls a callback sink, which could be set by the user (currently setup to the SDK's internal logger in core/dllmain.cpp). TODO: * Add a batch file to autogenerate all projects. * Add support for dedicated server. * Add support for client dll. Bugs: * Game crashes on the title screen after the UI script compiler has finished (root cause unknown). * Curl error messages are getting logged twice for the dedicated server due to the removal of all "DEDICATED" preprocessor directives to support isolating projects. This has to be fixed properly!

#ifndef CLIENT_DLL
CAI related stuff (see description) * Partially rebuild CGlobalVarsBase and CGlobalVars struct. * Partially implement BuildAINFile (disk builder) written by BobTheBob9. All that needs to be found are the addresses/offsets for 'pUnkStruct0Count' and 'pUnkLinkStruct1Count' (see ai_node.h). I didn't have time for it yet. * Patch call which restarts the engine once AIN file has been build (so it doesn't get cleared from memory). * Temporarily patch write operation in 'Detours_LevelInit()' which writes out of scope since the navmesh structure is misaligned somewhere still with a few bytes. NOTE: 'CAI_NetworkBuilder::BuildFile()' is for now commented out until the 2 other structs are found in the game dll. Once found then we could start fixing the struct offsets and hope it works as-is.

NavMesh hot swap system improvements * Check if server is active in command callback before attempting to hot swap. * Hook 'v_Detour_LevelInit', and log NavMeshes that failed to load. * Split free/destroy logic into separate function. * Created constants for NavMesh and AI Network paths/extensions. * Added performance profiler for hot swap logic in command callback. * Renamed "navmesh_reload" to "navmesh_hotswap". * "navmesh_hotswap" is now development only.

First work-in-progress dedicated implementation Based on MrSteyk's dedicated patch. Additional patches targets the disabling of the client.dll library and VGUI. The disabling of the client.dll library initialization caused several issues to be investigated still (currently loops fine in _Host_RunFrame()). but executing a map command currently makes it only load the mp_common VPK before getting stuck somewhere. Setting hoststate to a valid map with HS_NEW_GAME (manually) does something to the engine but does not force the server to load anything yet. Added enums and classes from r5dev project.

Code base refactor + major performance and readability improvement. Read description for details. * 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!).

Fix crash in 'CClient::ActivatePlayer' Set the persistence fields to 'ready' in 'CClient::ActivatePlayer', before executing the rest of the function. Previously, it was set in 'CVEngineServer::PersistenceAvailable', but this is too late. The function 'FairFight_Init' was actually 'CClient::ActivatePlayer', and thus it has been moved to the correct file, and the old file defining it previously has been removed.

IDetour: remove extraneous pointer assignments 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.
