Animating an Array of Images in an Applet</h3>
This is the simplest applet to animate an array of images.
In practice, you should use double-buffering (which this example does
not use) to eliminate <font color="#0066ff"><i>flickering</i></font>.
<pre>
import java.applet.*;
import java.awt.*;
public class <font color="#0066ff"><i>AnimApplet</i></font> extends Applet implements Runnable {
Image[] images = new Image[<font color="#0066ff"><i>2</i></font>];
int frame = 0;
volatile Thread thread;
public void init() {
images[0] = getImage(getDocumentBase(), <font color="#0066ff"><i>"http://hostname/image0.gif"</i></font>);
images[1] = getImage(getDocumentBase(), <font color="#0066ff"><i>"http://hostname/image1.gif"</i></font>);
}
public void start() {
(thread = new Thread(this)).start();
}
public void stop() {
thread = null;
}
public void paint(Graphics g) {
g.drawImage(images[frame], <font color="#0066ff"><i>0</i></font>, <font color="#0066ff"><i>0</i></font>, this);
}
public void run() {
int delay = <font color="#0066ff"><i>1000</i></font>; // 1 second
try {
while (thread == Thread.currentThread()) {
frame = (frame+1)%images.length;
repaint();
Thread.sleep(delay);
}
} catch (Exception e) {
}
}
}
