SDL_JoystickGetAxis(3) SDL API Reference SDL_JoystickGetAxis(3)NAMESDL_JoystickGetAxis - Get the current state of an axis
SYNOPSIS
#include "SDL.h"
Sint16 SDL_JoystickGetAxis(SDL_Joystick *joystick, int axis);
DESCRIPTIONSDL_JoystickGetAxis returns the current state of the given axis on the
given joystick.
On most modern joysticks the X axis is usually represented by axis 0
and the Y axis by axis 1. The value returned by SDL_JoystickGetAxis is
a signed integer (-32768 to 32768) representing the current position of
the axis, it maybe necessary to impose certain tolerances on these val‐
ues to account for jitter. It is worth noting that some joysticks use
axes 2 and 3 for extra buttons.
RETURN VALUE
Returns a 16-bit signed integer representing the current position of
the axis.
EXAMPLES
Sint16 x_move, y_move;
