leocholvy/rv_there_yet_steeringwheel_compatibility_mod

This project is a modification, distributed as a Windows DLL file, that adds proper steering wheel and pedal support to a driving game built on Unreal Engine, referred to in the code as RV Mod. It was tested with Logitech G920 and G29 wheels and supports H pattern gear shifters, letting players shift gears manually instead of relying on the keyboard or a generic gamepad mapping. The mod adds an in game settings window built with a graphical interface library called Dear ImGui, so players can configure everything, from wheel selection to force feedback strength, without editing text files or using a console. Force feedback, the resistance and vibration a wheel pushes back against the driver's hands, is calculated dynamically based on the vehicle's actual speed, includes resistance even while parked, and reduces automatically during jumps or when the vehicle loses grip. A calibration tool detects each wheel and pedal's minimum, center, and maximum values automatically, and gear binding is done simply by shifting into each gear while the tool watches. The mod reads wheel and pedal input directly through a library called SDL2 rather than emulating a different input device, which the author says removes the need for separate emulation software some other setups require. It was built using an Unreal Engine software development kit that the author generated with a tool called Dumper 7, which extracts the game's internal class structure so the mod can interact with it directly. To use the mod, players need the compiled DLL file and a way to load it into the running game process, such as a common DLL injector program, since the game itself has no built in support for loading it. The project is written in C++ using CMake and Microsoft's compiler, and the author describes it as a passion project, inviting bug reports and suggestions through GitHub issues.
