This is the revision of a game I built in Processing. As with version 1.0, this game uses a webcam to track color. In this case, the program is scanning the wall for the red dot of a laser pointed mounted on the toy gun. As opposed to version 1.0, this revision will track exactly where the gun is pointed and can thus gauge accuracy in addition to reaction speed. The toy gun is also fitted with the pressure sensor that is wired to an Arduino, which detects when the trigger has been pulled. In this version, the reaction speed is only counted if the player scores a "hit".
