SDL2: Xbox controller with wrong mappings?! about sdl HOT 4 CLOSED

Hi @lassade ,

That mapping looks right. The mapping string you generated with the Gamepad Tool looks the same as the default one, which is why it didn't change anything.

When you pressed the left shoulder in the Gamepad Tool, it produced the correct scancode and mapped it as expected. Something seems to be changing the behaviour of your app? I suspect that if you used your controller someone else's SDL app/game, it would be mapped ok? Try my Game Controller Tester app on itch.io to give you some more insights.

It work as expected, I also played Hades from Supergiant Games without any problems with it.

I have a very cursed workaround that uses SDL_GameControllerGetBindForButton that I use undo (or do) the binding like so:

// I think this is a valid c code, I'm acctually using zig :P
// reset binds
for(int i = 0; i < SDL_CONTROLLER_BUTTON_MAX) {
    binds[i] = i;
}
// de-map binds
for(int i = 0; i < SDL_CONTROLLER_BUTTON_MAX) {
    bind = SDL_GameControllerGetBindForButton(i);
    if (bind.bindType) binds[bind.value.button] = i;
}

Oh, yeah, SDL_GameControllerGetBindForButton(gamepad, SDL_CONTROLLER_BUTTON_LEFTSHOULDER) will give you a button index, not another gamepad button. You generally shouldn't be using the functions to look up bindings, they won't provide you with anything useful unless you're building a gamepad binding application.

Take a look at https://github.com/libsdl-org/SDL/blob/main/test/testcontroller.c for a complete example of using the SDL gamepad API.
