NAME
SDL_GetGamepadAxis - Get the current state of an axis control on a gamepad.
HEADER FILE
Defined in SDL3/SDL_gamepad.h
SYNOPSIS
#include "SDL3/SDL.h" Sint16 SDL_GetGamepadAxis(SDL_Gamepad *gamepad, SDL_GamepadAxis axis);
DESCRIPTION
The axis indices start at index 0. For thumbsticks, the state is a value ranging from -32768 (up/left) to 32767 (down/right). Triggers range from 0 when released to 32767 when fully pressed, and never return a negative value. Note that this differs from the value reported by the lower-level SDL_GetJoystickAxis (), which normally uses the full range.
FUNCTION PARAMETERS
gamepad a gamepad. axis an axis index (one of the SDL_GamepadAxis values).
RETURN VALUE
( Sint16 ) Returns axis state (including 0) on success or 0 (also) on failure; call SDL_GetError () for more information.
AVAILABILITY
This function is available since SDL 3.2.0.
