Java ImageIcon动画闪烁

问题描述：

当它切换图标的图像闪烁时形成某种原因。当我尝试创建对象时，我还遇到了这个问题，然后尝试通过将x和y作为参数传递给对象来移动它们。任何帮助都会很棒。Java ImageIcon动画闪烁

public class Main extends JFrame implements ActionListener, KeyListener{ 

static Main main; 
Render render; 
Timer timer; 

static int x,y,count; 

ImageIcon player1 = new ImageIcon("C:\\Users\\Kyle\\Documents\\NetBeansProjects\\Testing52\\src\\testing52\\Player1.png"); 
ImageIcon player2 = new ImageIcon("C:\\Users\\Kyle\\Documents\\NetBeansProjects\\Testing52\\src\\testing52\\Player2.png"); 

Main(){ 

    render = new Render(); 
    timer = new Timer(100,this); 

    setVisible(true); 
    setSize(500,500); 
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
    setResizable(false); 
    addKeyListener(this); 
    add(render); 

    timer.start(); 

} 

public void render(Graphics g){ 

    count += 1; 

    if(count < 20){ 
     player1.paintIcon(this, g, x, y); 
    } 

    if(count > 20){ 
     player2.paintIcon(this, g, x, y); 
    } 
    if(count > 40){ 
     count = 0; 
    } 

} 


public static void main(String [] args){ 

    main = new Main(); 
} 

@Override 
public void actionPerformed(ActionEvent e) { 

    System.out.println(count); 
    render.repaint(); 
} 

@Override 
public void keyTyped(KeyEvent e) { 
} 

@Override 
public void keyPressed(KeyEvent e) { 
    int id = e.getKeyCode(); 

    int speed = 4; 

    if(id == KeyEvent.VK_UP){ 

     y -= speed;  
    } 

    if(id == KeyEvent.VK_DOWN){ 

     y += speed; 
    } 

    if(id == KeyEvent.VK_LEFT){ 

     x -= speed; 
    } 

    if(id == KeyEvent.VK_RIGHT){ 

     x += speed; 
    } 
} 

@Override 
public void keyReleased(KeyEvent e) { 
} 

}

渲染类。

public class Render extends JPanel { 

public void paintComponent(Graphics g){ 
    super.paintComponent(g); 

    Main.main.render((Graphics)g); 
}

}

想通了。我不得不将“if（count> 20）”更改为“if（count> = 20）”。以及将“count + = 1”移动到ActionListener –

另一件事，可以使你的动画更流畅是，如果你在你的动作事件repaint()后调用revalidate()。
