SDL_JoystickGetAxis -- Get the current state of an axis
#include "SDL.h" Sint16 SDL_JoystickGetAxis(SDL_Joystick *joystick, int axis);
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 32767) representing the current position of the axis, it may be necessary to impose certain tolerances on these values to account for jitter.
Note: Some joysticks use axes 2 and 3 for extra buttons.
Returns a 16-bit signed integer representing the current position of the axis.
