我在 Java 中使用环境 Robocode，并试图创建一个机器人来对抗示例机器人 spinbot。我正在计算旋转机器人环绕的圆心，并使用它来瞄准以获得击中旋转机器人的最佳机会。我的代码编译得很好，但是当我运行它时，它永远不会进入 onScannedRobot(ScannedRobot e) 方法。我通过在不同点改变机器人的颜色来测试它，我可以说它从未进入过。

如果有人能告诉我做错了什么/如何修复它，以便代码进入这个方法，那就太好了，谢谢。

我不确定这是否已经得到解答或解决（我当然希望在 10 个月后如此），但供将来参考。只有在执行该方法或雷达波束移动ScannedRobotEvent时才会触发。Scan()
