這個循環在哪裏出錯？

我目前正在研究基於文本的Java RPG。每次玩家走過一定數量的步時，都會發生隨機戰鬥。每次運行戰鬥系統時，程序都會進入永久循環，屏幕會凍結。這個循環在哪裏出錯？

我該如何解決這個問題？這是所有這些處理的主類的代碼。

import javax.swing.*; 
import java.awt.event.*; 
public class Runner extends JFrame{ 

    String mat[][] = {{".",".",".",".",".",".",".",".",".","."}, 
         {".",".",".",".",".",".",".",".",".","."}, 
         {".",".",".",".",".",".",".",".",".","."}, 
         {".",".",".",".",".",".",".",".",".","."}, 
         {".",".",".",".",".",".",".",".",".","."}, 
         {".",".",".",".",".",".",".",".",".","."}, 
         {".",".",".",".",".",".",".",".",".","."}, 
         {".",".",".",".",".",".",".",".",".","."}, 
         {".",".",".",".",".",".",".",".",".","."}, 
         {".",".",".",".",".",".",".",".",".","."}, 
         {".",".",".",".",".",".",".",".",".","."}};

請改善您的問題：縮小問題範圍，確切地告訴我們無盡循環發生的位置（使用調試器！）。正確格式化並縮進代碼，並按照Java命名約定（方法名稱從不以大寫字母開頭）。附加提示：不要在事件派發線程中執行長操作。 – RealSkeptic

你需要改善你的問題，讓人們能夠幫助你。問題不在於「幫助我建立一個基於回合的戰鬥系統」，而是「幫助我找到這個無限循環」;問更具體的問題，你會得到更好的答案，你會更快地得到它們。（我現在正在改變這個問題的標題。） –

我會建議把重點放在你的戰鬥功能循環上。

while(battle == true){ 
     if(Burn == false) 
     { 
      en.attack((Fighter)p); 
      Burn = true; 
     } 
     if(p.getHp() <= 0) 
     { 
      battle = false; 
     } 
    }

如果是這樣的無限循環，它看起來好像p.getHP（）的終止條件是小於或等於0永不滿足。
