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);
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 values 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);
