Does it work with the Gamesir gamepads for mobile devices? What about 8 directional movement, does it recognize the up+left type commands? If so, we have a winner!
Viewing post in RPG Maker MZ Plugin: Controls Binder comments
This plugin only rebind controls, it doesn't add extra controller support and it doesn't change RPG Maker behaviour
For 8 directional control you need a 8 directional plugin active, if it's active then there is no problem using a controller (an 8 direction plugin should be available in the free dlc section of vanilla RPG Maker MZ)
As for Games or gamepads, I don't know if RPG Maker supports them natively, I'm sorry
