SDL_GamepadBinding

A mapping between one joystick input to a gamepad control.

Syntax

typedef struct SDL_GamepadBinding
{
    SDL_GamepadBindingType input_type;
    union
    {
        int button;

        struct
        {
            int axis;
            int axis_min;
            int axis_max;
        } axis;

        struct
        {
            int hat;
            int hat_mask;
        } hat;

    } input;

    SDL_GamepadBindingType output_type;
    union
    {
        SDL_GamepadButton button;

        struct
        {
            SDL_GamepadAxis axis;
            int axis_min;
            int axis_max;
        } axis;

    } output;
} SDL_GamepadBinding;

Remarks

A gamepad has a collection of several bindings, to say, for example, when joystick button number 5 is pressed, that should be treated like the gamepad's "start" button.

SDL has these bindings built-in for many popular controllers, and can add more with a simple text string. Those strings are parsed into a collection of these structs to make it easier to operate on the data.

Version

This struct is available since SDL 3.1.3.
