我不明白為什么我在運行此代碼時永遠不會進入onScannedRobot（ScannedRobot e）方法？

Question

我正在使用Java中的環境Robocode，並試圖創建一個與示例機器人Spinbot相對應的機器人。 我正在計算旋轉機器人繞過的圓圈的中心，並以此為目標以獲得擊中旋轉機器人的最佳機會。 我的代碼可以很好地編譯，但是當我運行它時，它永遠不會進入onScannedRobot（ScannedRobot e）方法。 我通過在不同位置更改機器人的顏色進行了測試，可以說它從未進入過。

如果有人能告訴我我做錯了/如何修復它，以便代碼進入此方法，那就太好了，謝謝。

我不確定這是否已得到解決（我肯定希望在10個月后如此），但確實可供將來參考。 ScannedRobotEvent僅在執行Scan()方法或雷達波束移動時觸發。
