我在java中第一次創建遊戲，我目前正試圖讓我的殭屍跟蹤並跟隨玩家。下面是我的代碼。我創建了一個控制器類，並使用鏈表創建多個殭屍。然後在我的殭屍更新方法中，我使用簡單的if語句來爲殭屍追蹤玩家。問題在於殭屍會追蹤玩家的初始起始位置，而不是他移動的位置。在殭屍更新（）方法中，我使用了System.println（player.getX（））;它表明玩家的位置並沒有在殭屍課上更新，所以這就是爲什麼他們只追蹤到它的起始位置。我無法弄清楚如何解決這個問題。任何幫助，將不勝感激。java：敵方玩家跟蹤AI的Java遊戲

是因爲我創建了殭屍類中的玩家類的參考。但是我已經在我的遊戲課中完成了這項工作，我將該玩家添加到了遊戲中？ – Phill
