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 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);
y_move=SDL_JoystickGetAxis(joy1, 1);
