Thread: Trying to fix repaint method

So I'm trying to move a rectangle... but it leaves footprints...repaint(); doesn't seem to work in actionPerformed

Thanks!

	private static final long serialVersionUID = 1L;
 
	Timer t = new Timer(5, this);

	int rectWidth = 80;

	int ballWH = 20;
 
	public myFrame() {
		t.start();
		addKeyListener(this);
		setFocusable(true);
		setFocusTraversalKeysEnabled(false);		
	}
 
	public void paintComponent (Graphics draw2D){		
 
		 //PAD		
		super.paintComponents(draw2D);
		Graphics2D draw = (Graphics2D) draw2D;
		draw.setColor(Color.red);
		draw.fill(new Rectangle2D.Double(rectX,rectY, rectWidth, rectHeight));
		draw.getClipBounds();  
		//BALL		
 
		/*draw.setColor(Color.blue);
		draw.fill(new Ellipse2D.Double(ballX,ballY,ballWH,ballWH));*/
 
	}
 
	public void actionPerformed (ActionEvent e) {
	        repaint();
		rectX += rectVeloX;
		rectY += rectVeloY;		
	}
 
 
 
 
	public void keyPressed(KeyEvent e) {
		int key = e.getKeyCode();
 
		   if (key == KeyEvent.VK_RIGHT ) {
 
			   rectVeloX = 1.5;
			   rectVeloY = 0;
 
 
	    }  if (key == KeyEvent.VK_LEFT ) {
 
			   rectVeloX = -1.5;
			   rectVeloY = 0;
 
 
	            //Left arrow key code
	    }
 
	}
 
	public void keyReleased(KeyEvent e) {
		int key = e.getKeyCode();
 
			if (key == KeyEvent.VK_RIGHT) {
				rectVeloX = 0;
				rectVeloY = 0;
 
			}
 
			if (key == KeyEvent.VK_LEFT) {
				rectVeloX = 0;
				rectVeloY = 0;
			}
	}
 
	public void keyTyped(KeyEvent e) {}		
}
 
 
import javax.swing.JFrame;
 
public class arkanoidGame {
 
	public static void main(String[] args) {
		JFrame frame = new JFrame();
		myFrame s = new myFrame();
		frame.add(s);
		frame.setVisible(true);
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setSize(800,600);
 
	}	
}

I fixed it by changing
public void paint(Graphics draw2D){
super.paint(draw2D);

You need to add if( key == KeyEvent.VK_DOWN) in keyReleased or else it won't stop

public void keyReleased(KeyEvent e) {
		int key = e.getKeyCode();
 
			if (key == KeyEvent.VK_RIGHT) {
				rectVeloX = 0;
				rectVeloY = 0;
 
			}
 
			if (key == KeyEvent.VK_LEFT) {
				rectVeloX = 0;
				rectVeloY = 0;
			}    
                        if( key == KeyEvent.VK_DOWN) {
                                rectVeloX = 0;
                                rectVeloY = 0;
	}

Should have realized that. (Probably would have if I wasn't sleep deprived.)
