Having the same problem other people seem to be:
The controller only works when the window has focus.
Meaning I can't use it to play with multiple people (why I used it).
Really weird since I know it's worked before. Even with no other mods added, it still doesn't work. I have a feeling it has something to do with windows 10, because last time i used it was on windows 8.
Xbox One Controllers
Just tested the 1.11 version, and that one does seem to work properly, aside from assigning new keys (only works if you create a new custom key)
Just tested the latest 1.7.10 version, JoypadMod-1.7.10-10.13.4.1614-1.7.10, and that doesn't work either, so it seems to be 1.7.10 as a whole that doesn't work. Really hope you can find a patch, because a lot of mods and modpacks didn't make it out of 1.7.
I am very grateful for this mod though, it allows me friends and i to all play together on one computer!
