Standalone VPK tool that does everything the VPK tool implemented in the dedicated server does (pack, unpack), but independent from the game's runtime.
Standalone FileSystem implementation, allowing SDK code to be used in tools without adjusting them as the vtables remain identical. NOTE that this reimplementation is partial and only contains the reading and writing of files to/from buffers or disk as that's what we are mainly interested at. We can always implement the other methods when needed.
NOTE: the filesystem singleton accessor (CFileSystem_Stdio* FileSystem()) has been moved to an implementation file instead of being inline as this would allow existing code to link to the tools implementation instead.
The KeyValues class belongs here. Also reimplemented most loading methods for KeyValues, and adjusted the VPK building code to account for it. Pointers to the engine's implementation of KeyValues have been moved to a separate header ('keyvalues_iface.h'), as this allows external tools code to utilize the standalone KeyValues class implementation. Playlist utilities are completely separated from the KeyValues header; these have nothing to do with KeyValues other than manipulating a global KeyValues object for the playlists, and thus have been named as such and moved to rtech/playlists.
Class is slightly modified; it uses 2 CBlob pointers instead of a single CBlob member. CUtlMemoryPool::m_pHeadOfFreeList is also replaced with the new CUtlMemoryPool::m_pPrev pointer. Code has been modified to accommodate this change and aligns with the assembly code of r5.
This is a more reliable solution as pretty much all code patch in CMDLCache checks the ptr for NULL, but none of them do for 0xDEADFEEDDEADFEED (probably a debug only thing that somehow made it into this build). Patched out so the engine could deal with it properly. Anything interesting already gets logged from the SDK so we won't miss out on anything patching this out.
Add a proper class for dealing with fallback models and the warnings thereof. Also reverted the 'old_gather_props' removal, as otherwise fallback models won't draw (new gather props solution doesn't call CMDLCache::GetHardwareData()).
Rebuild 'CMDLCache::GetPhysicsGeometry()' and properly handle missing cache pointers. Also cleaned up various methods in CMDLCache and renamed 'studiophysicscache_t' to 'studiophysicsref_t'. The changes made the 'old_gather_props' convar hack redundant and has thus been removed.
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.
These are hardcoded delay values for if you want to pick and swap an item from the ground. Perhaps nice to make a cvar and an in-game UI setting for adjusting them.
Blocking it all together will cause problem when user wants to reset their controller binds. Now we limit execution to 4 per second (default) which doesn't cause problems when resetting any configuration, while also preventing cfg hacks.
