I want to make a level to the user can configure their axis inside the game, not in the splash screen…
¿Is there a way?
Not sure if I understand your question…are you asking if/how you can configure input axes via scripting rather than via the graphics/input dialog that (optionally) opens when you launch your application?
If so, the short answer is, you can’t. But, there are other ways you can get the effect of in-game input configuration.
