i searched for info about how to set up user key rebindings (via an in game options menu like all games have) and the only stuff i could find was from 2015 and contained numerous broken links.
what is the best way in the unity 2019 to edit and use key binding in a clean and consistent way.
If you can afford it, I’d highly recommend the Rewired Asset on the Unity Asset Store (currently $45 I think). I’ve no affiliation with them, but found it to be way better (and easier to use) for user input and rebindings than Unity’s own solution.
