連接4 Java項目 - 確定列滿時的問題

Question

if (count % 2 == 0) { 

    int columnMove; 
    System.out.print("Player one, please enter a move or q to quit: "); 
    columnMove = scan.nextInt() - 1; 

    if (columnMove <= columns - 1 && columnMove >= 0) { 
     turns = true; 
     game.playerOnePrompt(board, columns, rows, columnMove); 
     ++count; 
     if (board[0][columnMove] != "_") { 
      System.out.println("This column is full"); 
      count = 0; 
     } 
    } else { 
     System.out.println("Invalid move"); 
     count = 0; 
    } 

} else { 

    int columnMove; 
    System.out.print("Player two, please enter a move: "); 
    columnMove = scan.nextInt() - 1; 

    if (columnMove <= columns - 1 && columnMove >= 0) { 
     turns = true; 
     game.playerTwoPrompt(board, columns, rows, columnMove); 
     count++; 
     if (board[0][columnMove] != "_") { 
      System.out.println("This column is full"); 
      count = 1; 
     } 
    } else { 
     System.out.println("Invalid move"); 
     count = 1; 
    } 
} 

您好！以上是我的代碼來確定數組（列）是否已滿，如果它已滿，用戶應該提示再次移動。

但是我有一個問題，程序發現它已滿，提示用戶，並且在用戶進行有效的移動之後，程序不會移動玩家（從玩家1-2-2-2等） ）。

有什麼建議嗎？

Answer 1

你的問題是在這裏：

if (board[0][columnMove] != "_") 
    { 
     System.out.println("This column is full"); 
     count = 0; 
    } 

你總是設置計數爲零，每當此舉是有效的。

Answer 2

maximumNumberOfMoves = boardWidth * boardHeight; 
    if (count == maximumNumberOfMoves) { 
     // end game 
    } else if (count % 2 == 0) { 
     int columnMove; 
     System.out.print("Player one, please enter a move or q to quit: "); 
     columnMove = scan.nextInt() - 1; 
     if (columnMove <= columns - 1 && columnMove >= 0) { 
      turns = true; 
      game.playerOnePrompt(board, columns, rows, columnMove); 
      ++count; 
      if (board[0][columnMove] != "_") { 
       System.out.println("This column is full"); 
       --count; // We must decrement count if we want the same 
          // player to move again 
      } 
     } else { 
      System.out.println("Invalid move"); 
      // count = 0; //Remove this, count was not modified 
     } 

    } else { 
     int columnMove; 
     System.out.print("Player two, please enter a move: "); 
     columnMove = scan.nextInt() - 1; 
     if (columnMove <= columns - 1 && columnMove >= 0) { 
      turns = true; 
      game.playerTwoPrompt(board, columns, rows, columnMove); 
      count++; 
      if (board[0][columnMove] != "_") { 
       System.out.println("This column is full"); 
       --count; // We must decrement count if we want the same 
          // player to move again 
      } 
     } else { 
      System.out.println("Invalid move"); 
      // count = 1; //Again, remove this since count is not modified 
     } 
    } 

注爲固定代碼

這個答案假定計數註釋行代表了迄今所取得移動號碼，並開始爲0
