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.
