Constructor & Destructor Documentation

GameController::GameController ( QObject *  parent = 0 )

explicit

By default, the game controller selects the "first" joystick, printing a warning if there are multiple joysticks On Linux, this is /dev/input/js0 If no joystick is found, it will print an error message, and will return zero. It is possible to change/add a joystick later with findNewController

void GameController::findNewController

Re-run the joystick finding code to select the "first" joystick. This can be used to set up the joystick if the simulator is started without a joystick plugged in
