@TheSceriffo So since you most likely don’t have gloves that can track your hand signs for a fireball jutsu, you’re probably going to need to create animation blueprints for the hands. Then, on whichever your desired input is, (motion tracking or buttons) then have it navigate through the input structure. I’d probably recommend keeping the hands together, but apart would allow much more room for diverse actions but would be drastically harder to code. But then, if you wanted a Rasengan at some point, all it would take would be lowering your hand for a period of time.
It’s a really cool idea though, I’d love to see updates.
I hope this can help!
