sdlGameControllerGetAxis function

int sdlGameControllerGetAxis(Pointer<SdlGameController> gamecontroller, int axis)

Get the current state of an axis control on a game controller.

The axis indices start at index 0.

For thumbsticks, the state is a value ranging from -32768 (up/left) to 32767 (down/right).

Triggers range from 0 when released to 32767 when fully pressed, and never return a negative value. Note that this differs from the value reported by the lower-level SDL_GetJoystickAxis(), which normally uses the full range.

\param gamecontroller a game controller \param axis an axis index (one of the SDL_GameControllerAxis values) \returns axis state (including 0) on success or 0 (also) on failure; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.0.
