鼠標點擊java

我遵循了關於在java中創建迷宮遊戲的教程。完成後，我決定添加一些東西（主菜單，更多關卡等）。我目前卡在主菜單，因爲我無法讓鼠標輸入工作。當我在開始遊戲框中點擊左鍵時，我正嘗試切換到屏幕= 1。這是我當前的課程代碼。鼠標點擊java

      System.out.println("2");

       screen=1;

    public class Al extends KeyAdapter{ 
     public void keyPressed(KeyEvent e){ 
      int keycode = e.getKeyCode(); 
      if((keycode == KeyEvent.VK_W) || (keycode == KeyEvent.VK_UP)){ 
       if(!m.getMap(p.getTileX(),p.getTileY() -1).equals("w")){ 
        p.move(0, -1); 
       } 
      } 
      if((keycode == KeyEvent.VK_A) || (keycode == KeyEvent.VK_LEFT)){ 
       if(!m.getMap(p.getTileX()-1,p.getTileY()).equals("w")){ 
       p.move(-1, 0); 
       } 
      } 
      if((keycode == KeyEvent.VK_D) || (keycode == KeyEvent.VK_RIGHT)){ 
       if(!m.getMap(p.getTileX()+1,p.getTileY()).equals("w")){ 
        p.move(1, 0); 
       } 
      } 
      if((keycode == KeyEvent.VK_S) || (keycode == KeyEvent.VK_DOWN)){ 
       if(!m.getMap(p.getTileX(),p.getTileY() +1).equals("w")){ 
        p.move(0, 1); 
       } 
      } 
     } 
     public void keyReleased(KeyEvent e){ 

     } 
     public void keyTyped(KeyEvent e){ 

     } 
    } 
}

我用「System.out.println（」1「）;」看看它是否註冊了鼠標按鍵，但它不打印。

當你把'後的System.out.println（「1」）;'之外的if語句，它仍然沒有按不打印？另外，爲什麼要打印？只是把一個斷點和調試？（即使沒有使用IDE，也可以這樣做，儘管可以幫助...） –

你的問題是什麼，我看到

您已經實現的mousePressed用大寫M

 public void MousePressed(MouseEvent e){ 
      int mx = e.getX(); 
      int my = e.getY(); 
      System.out.println("2"); 
      if((screen ==0) && start2.contains(mx,my)){ 
       screen=1; 
       System.out.println("1"); 
      } 
     }

，並用小寫字母m大寫：

public void mousePressed(MouseEvent e) { 

    }

簡單地改變大寫M以小寫m和刪除冗餘鼠標按下呼叫

例如

public class A2 extends MouseAdapter{ 
    public void mousePressed(MouseEvent e){ 
     int mx = e.getX(); 
     int my = e.getY(); 
     System.out.println("2"); 
     if((screen ==0) && start2.contains(mx,my)){ 
      screen=1; 
      System.out.println("1"); 
     } 
    } 
    public void mouseClicked(MouseEvent e) { 

    } 
    public void mouseEntered(MouseEvent e) { 

    } 
    public void mouseExited(MouseEvent e) { 

    } 
    public void mouseReleased(MouseEvent e) { 

    } 
}

謝謝，這是問題所在。我一直在爲它工作幾個小時>< – Chad

很高興幫助:)如果你想（沒有壓力），你可以標記答案爲接受 –

你遇到的主要問題是你命名你的鼠標按下方法不正確地

變化

public void MousePressed(MouseEvent e)

要

我會建議比你使用@Override註釋，如果你這樣做會導致編譯器錯誤istake

我還鼓勵使用KeyListener上的鍵綁定API和paintComponent上的paint。

您也可以找到一個電話重繪更改屏幕變量將更新屏幕

是的。 +1提到'@ Override' –
