內部監聽器和計時器的足球遊戲程序

-1

我想知道如何將一個Timer和我的所有監聽器應用爲內部類。我仍然對內部類感到困惑，所以有人可以解釋，我怎樣才能將它應用到我自己的程序中，這將非常感激。我剛剛學會了計時器，但我不確定在哪裏以及如何設置它。我想設定60秒。內部監聽器和計時器的足球遊戲程序

這裏是我的代碼：

package runningback; 

import java.awt.*; 
import javax.swing.*; 
import java.awt.event.*; 

public class MainPanel extends JPanel implements KeyListener 
{ 
    JLabel text = new JLabel("Touchdowns: "); 
    JLabel text2 = new JLabel("Tackles: "); 
    JLabel touchdownsLbl; 
    JLabel tacklesLbl; 
    JButton movingButton = new JButton("key code"); 
    JButton startBtn = new JButton("Start"); 
    JLabel background=new JLabel(new ImageIcon("playground.png")); 
    JLabel rb=new JLabel(new ImageIcon("rb.png")); 
    JLabel tackler=new JLabel(new ImageIcon("tackler.png")); 
    int x =0; 
    int y = 10; 
    int touchdowns; 
    int tackles; 
    Player mainPlayer; 
public MainPanel() 
{ 
     mainPlayer = new Player(); 
     touchdowns = 0; 
     tackles = 0; 
     touchdownsLbl = new JLabel(Integer.toString(touchdowns)); 
     tacklesLbl = new JLabel(Integer.toString(tackles)); 

     setLayout(null); 
     //setBackground(Color.pink); 
     add(text); 
     add(text2); 
     add(touchdownsLbl); 
     add(tacklesLbl); 
     text.setBounds(new Rectangle(350, 20, 350, 30)); 
     text2.setBounds(new Rectangle(450, 20, 350, 30)); 
     touchdownsLbl.setBounds(new Rectangle(435, 20, 350, 30)); 
     tacklesLbl.setBounds(new Rectangle(505, 20, 350, 30)); 
     setFocusable(true); 
     addKeyListener(this); 
     add(rb); 
     add(background); 
     background.setBounds(new Rectangle(0, 94, 624, 416)); 

     rb.setBounds(new Rectangle(mainPlayer.x, mainPlayer.y, 50, 44)); 
     //add(movingButton); 
     startBtn.setBounds(new Rectangle(250, 20, 80, 30)); 
     add(startBtn); 
     startBtn.addActionListener(new ActionListener(){ 
      public void actionPerformed(ActionEvent e) { 
       //System.out.println("Button Pressed"); 
       gameReset(); 
      } 
     }); 
    //---------------------TIMER------------------------------ 
     int delay = 1000; // milliseconds 
     tim = new Timer(delay,this); 

     tim.start(); // starts the timer 
     //---------------------TIMER------------------------------ 
     tim.setDelay(200); // sets a new delay 
     tim.stop(); // stops the timer // stops the timer 
    } 

     } 
public void keyPressed(KeyEvent evt) 
{ 
//System.out.println("Key pressed"); 
int kk = evt.getKeyCode(); 
if(kk == evt.VK_LEFT) {mainPlayer.x=mainPlayer.x-mainPlayer.speed;} 
if(kk == evt.VK_RIGHT) {mainPlayer.x=mainPlayer.x+mainPlayer.speed;} 
if(kk == evt.VK_UP) {mainPlayer.y=mainPlayer.y-mainPlayer.speed;} 
if(kk == evt.VK_DOWN) {mainPlayer.y=mainPlayer.y+mainPlayer.speed;} 
update(); 
//movingButton.setText(""+evt.getKeyCode()+","+evt.getKeyChar()); 
//movingButton.setBounds(new Rectangle(x,y,80,30)); 
} 

void update(){ 
rb.setBounds(new Rectangle(mainPlayer.x, mainPlayer.y, 50, 44)); 
} 

void gameReset(){ 
    mainPlayer.x = 30; 
    mainPlayer.y = 280; 
    update(); 
} 
public void keyReleased(KeyEvent evt) { } 
public void keyTyped(KeyEvent evt) { } 
public void paintComponent(Graphics g) 
{ 
    //System.out.println("Painting"); 
    super.paintComponent(g); 
    requestFocusInWindow(); 
} 

    @Override 
    public Dimension getPreferredSize() { 
     return new Dimension(624, 500); 
} 

}

您已經在使用上面一些你的ActionListeners的「內部」類 - 所以請註明儘可能它是什麼，究竟是混淆你。我們越理解這個問題，通常答案就越好。我自己，我有點困惑，爲什麼你要調用'requestFocusInWindow（）;'paintComponent方法內部。這看起來像是一件危險的事情，我不確定你什麼時候會想要這種功能。 –

另外，我沒有看到上面的任何定時器代碼，所以請澄清你的意思。你指的是一個Swing Timer（javax.swing.Timer）實例嗎？ –

我想出了我的內部類，並添加了一個計時器。 int delay = 1000; //毫秒 tim = new Timer（delay，this）; tim.start（）; //啓動計時器 tim.setDelay（200）; //設置新的延遲 tim.stop（）; //停止計時器//停止計時器 –

public class MainPanel { 
    // setting timer 
    public void startTimer(double delay){ 
     long milisecond = 1000l; 
     Timer t = new Timer((int) (delay*milisecond), new TimerListener()); 
     t.setInitialDelay((int) (delay*milisecond)); 
     t.start(); 
    } 

    // inner classes 
    public class TimerListener implements ActionListener{...} 
    public class KeyListener extends KeyAdapter{...} 
}
