      • GUN_TURN_RATE

        public static final double GUN_TURN_RATE
        The turning rate of the gun measured in degrees, which is 20 degrees/turn. Note, that if setAdjustGunForRobotTurn(true) has been called, the gun turn is independent of the robot turn. In this case the gun moves relatively to the screen. If setAdjustGunForRobotTurn(false) has been called or setAdjustGunForRobotTurn() has not been called at all (this is the default), then the gun turn is dependent on the robot turn, and in this case the gun moves relatively to the robot body.

        GUN_TURN_RATE_RADIANS, Robot.setAdjustGunForRobotTurn(boolean), Constant Field Values
      • GUN_TURN_RATE_RADIANS

        public static final double GUN_TURN_RATE_RADIANS
        The turning rate of the gun measured in radians instead of degrees.
        See Also:
        GUN_TURN_RATE
      • RADAR_TURN_RATE

        public static final double RADAR_TURN_RATE
        The turning rate of the radar measured in degrees, which is 45 degrees/turn. Note, that if setAdjustRadarForRobotTurn(true) and/or setAdjustRadarForGunTurn(true) has been called, the radar turn is independent of the robot and/or gun turn. If both methods has been set to true, the radar moves relatively to the screen. If setAdjustRadarForRobotTurn(false) and/or setAdjustRadarForGunTurn(false) has been called or not called at all (this is the default), then the radar turn is dependent on the robot and/or gun turn, and in this case the radar moves relatively to the gun and/or robot body.
