Update Steamworks SDK 1.53 Resolve deprecated SteamNetworkingSockets usage Add ISteamInput interface to managed and callback forwarders Controller API using Steam Input; glyph textures, multiple controller support, analog states, etc. Use C# Controller API in InputBuilder to replicate default Source behaviour with Steam Input & disable XInput devices in C++ engine Don't spam the Event.Controller events if Steam Input spams us, derive Controller hash code from handle, add missing AnalogAction glyph getter Add action manifest files and load them, add default configs for Xbox One / PS4 controllers ( I think everything else should derive from this )
