NAME
SDL_GamepadAxis - The list of axes available on a gamepad
SYNOPSIS
#include <SDL3/SDL_gamepad.h>
typedef enum SDL_GamepadAxis
{
SDL_GAMEPAD_AXIS_INVALID = -1,
SDL_GAMEPAD_AXIS_LEFTX,
SDL_GAMEPAD_AXIS_LEFTY,
SDL_GAMEPAD_AXIS_RIGHTX,
SDL_GAMEPAD_AXIS_RIGHTY,
SDL_GAMEPAD_AXIS_LEFT_TRIGGER,
SDL_GAMEPAD_AXIS_RIGHT_TRIGGER,
SDL_GAMEPAD_AXIS_COUNT
} SDL_GamepadAxis;
DESCRIPTION
Thumbstick axis values range from SDL_JOYSTICK_AXIS_MIN to SDL_JOYSTICK_AXIS_MAX, and are centered within
~8000 of zero, though advanced UI will allow users to set or autodetect the dead zone, which varies
between gamepads.
Trigger axis values range from 0 (released) to SDL_JOYSTICK_AXIS_MAX (fully pressed) when reported by
SDL_GetGamepadAxis(). Note that this is not the same range that will be reported by the lower-level
SDL_GetJoystickAxis().
AVAILABILITY
This enum is available since SDL 3.2.0.
