SDL_JoystickGetAxis(3) SDL API Reference SDL_JoystickGetAxis(3)
NAME
SDL_JoystickGetAxis - Get the current state of an axis
SYNOPSIS
#include "SDL.h"
Sint16 SDL_JoystickGetAxis(SDL_Joystick *joystick, int axis);
DESCRIPTION
SDL_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;
SDL_Joystick *joy1;
.
.
x_move=SDL_JoystickGetAxis(joy1, 0);
y_move=SDL_JoystickGetAxis(joy1, 1);
