The crash only happened when the game executable had the ASLR flag set, because only then the pointer value overflowed the int32 type due to my bad cast
The game uses 2 types, CSquirrelVM (mostly exposed to the VScript API of the engine) and HSQUIRRELVM (mostly used for internal squirrel functions like sq_pushbool etc..).
This refactor properly splits the CSquirrelVM* functions from the HSQUIRRELVM (SQVM*) ones. The functions have also been renamed accordingly and the prototypes have been adjusted to use the correct pointer type.
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.
* Return global pointer with 'KeyValuesSystem()'.
* Declare 'bCreate' as false by default for 'GetSymbolForString()' and 'GetSymbolForStringCaseSensitive()'.
* 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 proper pointer to g_pFileSystem_Stdio.
* Renamed existing one to g_pFullFileSystem (correct name).
* Obtain g_pFileSystem from the same constructor as g_pFileSystem_Stdio.
* 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.
Load ui_sdk.rpak after ui_mp.rpak.
Moved the loading of common_sdk.rpak to after common_sp.rpak/common_mp.rpak.
This should allow overriding existing assets.
* Fixed compiler error when trying to compile SDK Launcher in debug (static lib was not compiled with static link runtime).
* Documented most stuff in basepanel.cpp
* Split some logic into dedicated functions in basepanel.cpp
* Implemented VDF parser from Matthias Moeller.
* Parse playlist file and load all playlists into the combo box.
Moved logging functions to dbg.h (tier0) and export them from the dll.
Added additional functions for checking bad pointers (debug only!).
Reduced output code size.
* Finished designer code for launcher gui.
* Basic implementation of setting flags for host launch option.
* Check in 'CHostState::LoadConfig' if -launcher is below 1.. if condition is met the cfg's will be executed from 'CHostState::LoadConfig'.
* Added 'StringIsDigit' utility.
