滑塊拼圖問題

這是我的滑塊拼圖遊戲。到目前爲止，它只能做3x3遊戲。當我嘗試傳遞板的變量l和w（長度和寬度）時，它不起作用。它只適用於當我設置變量ROWS和COLS爲決賽。當我嘗試改變它時，我收到錯誤。我不知道該怎麼做，任何幫助，將不勝感激。滑塊拼圖問題

目前用戶可以輸入目前無法做任何事情的值。遊戲開始時，會生成一個3x3的棋盤。用戶可以使用不同的加擾板重新開始遊戲，但解決棋盤上的按鈕和將板重置爲原始狀態的按鈕不起作用。

public class SlidePuzzle { 

public static void main(String[] args) 
{ 

    JFrame window = new JFrame("Slide Puzzle"); 
    window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
    String length = JOptionPane.showInputDialog("Length"); 
    String width = JOptionPane.showInputDialog("Width"); 
    int l = Integer.parseInt(length); 
    int w = Integer.parseInt(width); 
    window.setContentPane(new SlidePuzzleGUI()); 
    window.pack(); 
    window.show(); 
    window.setResizable(false); 

} 
} 

public class SlidePuzzleGUI extends JPanel 
{ 

private GraphicsPanel _puzzleGraphics; 
private SlidePuzzleModel _puzzleModel = new SlidePuzzleModel();

這個類包含了拼圖

public SlidePuzzleGUI() { 

    JButton newGameButton = new JButton("New Game"); 
    JButton resetButton = new JButton("Reset"); 
    JButton solveButton = new JButton("I GIVE UP :("); 

    resetButton.addActionListener(new ResetAction()); 
    newGameButton.addActionListener(new NewGameAction()); 


    JPanel controlPanel = new JPanel(); 
    controlPanel.setLayout(new FlowLayout()); 
    controlPanel.add(newGameButton); 
    controlPanel.add(resetButton); 
    controlPanel.add(solveButton); 


    _puzzleGraphics = new GraphicsPanel(); 

    this.setLayout(new BorderLayout()); 
    this.add(controlPanel, BorderLayout.NORTH); 
    this.add(_puzzleGraphics, BorderLayout.CENTER); 
}

你得到了什麼錯誤，在哪裏？ –

好吧，現在你輸入的是長度和寬度，但不對它們做任何事情，並且在'GraphicsPanel'中對行和列使用常量。可能將長度和寬度參數添加到'SlidePuzzleGUI'構造函數和'GraphicsPanel'構造函數中？然後，主程序在構造'SlidePuzzleGUI'時使用它們，並且在構造'GraphicsPanel'時使用'SlidePuzzleGUI' ......或者還有其他一些問題嗎？ – ajb

你重點班有沒有setter方法或構造函數的參數，使您可以通過長和寬度給他們。如果你想改變他們國家的這一方面，那麼他們必須有一個機制來做到這一點。目前你的GraphicsPanel被硬編碼以使用ROWS和COLS常量，這將很難改變。相反，將所有這些硬編碼替換爲變量，並確保它們默認爲默認構造函數中的ROWS和COLS常量，但也提供了一個非默認構造函數，允許程序員通過不同的行和列設置。

編輯
你得

使用構造函數的參數來設定類領域，使整個類可以使用這些值，而不僅僅是構造函數。
致電正確的構造函數，需要參數！

即

public MyConstructor(int x, int y) { 
    this.x = x; 
    this.y = y; 
}

我試圖把它們放在構造函數的參數中，但是這給了我錯誤，如果你給我一分鐘我可以重新鍵入我之前嘗試的內容 – user2776808

@ user2776808：將更改後的代碼添加到當前文章的底部，但保留當前代碼也到位。 –
