Use this function to find the current state of, enable, or disable events dealing with Game Controllers. This will not disable Joystick events, which can also be fired by a controller (see SDL_JoystickEventState()).
int SDL_GameControllerEventState(int state)
can be one of SDL_QUERY, SDL_IGNORE, or SDL_ENABLE
Note: You may use -1, 0, or 1 in place of SDL_QUERY, SDL_IGNORE, or SDL_ENABLE respectively.
Returns the same value passed to the function, with exception to -1 (SDL_QUERY), which will return the current state.
printf("%i\n", SDL_GameControllerEventState(SDL_QUERY)); /* prints 1 */ printf("%i\n", SDL_GameControllerEventState(SDL_IGNORE)); /* prints 0 */ printf("%i\n", SDL_GameControllerEventState(SDL_QUERY)); /* prints 0 */
If controller events are disabled, you must call SDL_GameControllerUpdate() yourself and check the state of the controller when you want controller information.
Any number can be passed to SDL_GameControllerEventState(), but only -1, 0, and 1 will have any effect. Other numbers will just be returned.
This function is available since SDL 2.0.0.
