So it IS in BL but it requires a mod. Great.
Realistically, though, it's not really something that would work well in BL.Maybe for building somewhat, but that's it.
I wanted to use the keyboard for building. The controller would be for games that dont involve building like TDMs or Speedkarts.
Somebody link him to that Coding Help topic. I'm not sure where it went.
