生命遊戲的問題

Question

我不知道我是否以正確的方式開展工作，我已經創建了適用於所有「靜物」單元安排的代碼，即。蜂巢，塊，船和麪包。然而，對於那些被認爲是被操縱並涉及細胞死亡和分娩的安排，我有問題。

現在，我先創建單元格，然後殺掉任何屬於規則的人（如果周圍的鄰居總數小於或等於1，等於或大於4）。

我現在走的是什麼，不應該如何應對。我包括我的代碼下面一些圖片：

public class Untitled { 
    public static void main(String[] params){ 
     Life life = new Life(); 
     String[][] list = life.readGame(); 

     life.print(list); 
     System.out.println(); 

     for(int i = 1; i <= 5; i++){ 
      list = life.run(list); 
      life.print(list); 
      System.out.println(); 
     } 
    } 
} 

class Life { 
    public String[][] readGame(){ 
     String[][] array = { 
       { "-","-", "-", "-", "-", "-","-"}, 
       { "-","-", "-", "-", "-", "-","-"}, 
       { "-","-", "-", "x", "-", "-","-"}, 
       { "-","-", "-", "x", "-", "-","-"}, 
       { "-","-", "-", "x", "-", "-","-"}, 
       { "-","-", "-", "-", "-", "-","-"}, 
       { "-","-", "-", "-", "-", "-","-"} 
     }; 
     return array; 
    } 

    public void print(String[][] array){ 
     for(int x = 0; x < array.length; x++){ 
      for(int y = 0; y < array[x].length; y++){ 
       System.out.print(array[x][y]); 
      } 
      System.out.println(); 
     } 
    } 

    public String[][] run(String[][] array){ 
     populateCells(array); 
     System.out.println("Populated:\n"); 
     print(array); 
     killCells(array); 
     System.out.println("Killed:\n"); 
     print(array); 
     return array; 
    } 

    public int amountOfNeighbors(String[][] array, int x, int y){ 
     int amount = 0; 

     for(int x1 = -1; x1 <= 1; x1++){ 
      if(x + x1 >= 0 && x + x1 < array.length){ 
       for(int y1 = -1; y1 <= 1; y1++){ 
        if(y + y1 >= 0 && y + y1 < array[x1 + x].length){ 
         if(!(x1 == 0 && y1 == 0) && !array[x1 + x][y1 + y].equals("-")){ 
          amount++; 
         } 
        } 
       } 
      } 
     } 
     return amount; 
    } 

    public void populateCells(String[][] array){ 
     int neighbours; 

     for(int x = 0; x < array.length; x++){ 
      for(int y = 0; y < array[x].length; y++){ 
       neighbours = amountOfNeighbors(array,x,y); 

       if(neighbours == 3){ 
        array[x][y] = "x"; 
       } 
      } 
     } 
    } 

    public void killCells(String[][] array){ 
     int neighbours; 

     for(int x = 0; x < array.length; x++){ 
      for(int y = 0; y < array[x].length; y++){ 
       neighbours = amountOfNeighbors(array,x,y); 

       if(neighbours <= 1 || neighbours >= 4){ 
        array[x][y] = "-"; 
       } 
      } 
     } 
    } 
} 

至於圖像，這裏有一個簡單的信號燈細胞的結構和人口和刪除後會發生什麼：

Answer 1

每次撥打電話run()您需要cr請先複製原始電路板的副本，並在修改原始電路板中的單元格時使用該副本檢查每個單元格的狀態。

否則，每次更新單元格時，都會無意中更改其單元格的狀態。

這是在涉及遊戲板像生命遊戲模擬一個相當普遍的錯誤 - 現在你知道要提防它:)
