Double Buffering [UNSOLVED]

Tue, 03 Nov 2009 18:15:32 -0700

I'm new to java and am working my way through a tutorial but I want to know how to add double buffering to the code below. The tutorial's code doesn't work, so how do you guys do it? (commented code is helpful

// DOUBLE BUFFERING

import java.applet.*;
import java.awt.*;




public class Game2p2 extends Applet implements Runnable
{
	int x_pos = 10;
	int y_pos = 100;
	int radius = 20;
	
	public void init() {}
	

	public void start(){
		//define a new thread
		Thread th = new Thread(this);
		// start this thread
		th.start();
	}
	
	
	public void stop() {}
	
	
	public void destroy(){}
	
	public void run() {
		// lower ThreadPriority
		Thread.currentThread().setPriority(Thread.MIN_PRIO
RITY);
		
		// run a long while (true) this means in our case 'allways'
		while(true){
			// repaint the applet
			x_pos++;
			repaint();
			
			try{
				// Stop thread for 20 milliseconds
				Thread.sleep(20);
			}
			catch(InterruptedException ex){
				// do nothing
			}
			
			// set ThreadPriority to maximum value
			Thread.currentThread().setPriority(Thread.MAX_PRIO
RITY);
		}
		
	}
	
	public void paint(Graphics g){
		// set color
		g.setColor(Color.red);
		
		// paint a filled colored circle
		g.fillOval(x_pos - radius, y_pos - radius, 2*radius, 2*radius);
	}
}
