Expand description

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

The axis indices start at index 0.

The state is a value ranging from -32768 to 32767. Triggers, however, range from 0 to 32767 (they never return a negative value).

\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.
