Animating an Array of Images in an Applet
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 ``flickering.''
import java.applet.*;
import java.awt.*;
public class AnimApplet extends Applet
implements Runnable {
Image[] images = new Image[2];
int frame = 0;
volatile Thread thread;
public void init() {
images[0] = getImage(getDocumentBase(),
"http://hostname/image0.gif");
images[1] = getImage(getDocumentBase(),
"http://hostname/image1.gif");
}
public void start() {
(thread = new Thread(this)).start();
}
public void stop() {
thread = null;
}
public void paint(Graphics g) {
g.drawImage(images[frame], 0, 0, this);
}
public void run() {
int delay = 1000; // 1 second
try {
while (thread == Thread.currentThread()) {
frame = (frame+1)%images.length;
repaint();
Thread.sleep(delay);
}
} catch (Exception e) {
}
}
}
