Hi,
this is not so complicated.
clone the repository: GitHub - tsky1971/UEJoystickPlugin: Unofficial Joystick Plugin for the Unreal Engine
checkout branch 4.11 (if binary api not changed there are compiled dll´s)
copy the content to your project -> be sure your project has source and vs project before copy
if you want to recompile run: (E:\Unreal Projects\JoystickDemo411\Plugins\JoystickPlugin\ThirdParty\SDL2) setup and build (if your system has all dependencies (directx, winsdk etc.) it will say success at the end)
Here is a complete project.
I did not make action bindings. So no action with joystick. I use this plugin in my lab projects nearly every day… so it works.
Here is a compiled version Plugin only.
