java - Robocode - 枪不指向与雷达相同的方向

Question

 public void onScannedRobot(ScannedRobotEvent e) {
     double angleToE = getHeading()+e.getBearing();
     double radarTurn = Utils.normalRelativeAngleDegrees(angleToE - getRadarHeading());
     setTurnRadarRight(2*radarTurn);
     setTurnGunRight(2*radarTurn);
     if(e.getDistance()<100){
         if(getEnergy()>50) fire(3);
         else fire(2);
     }
     else fire(1);
 } 

雷达工作正常，但即使我将枪旋转到与雷达相同的角度，它也只是随机射击。
