动画小程序实现的基本步骤

若何在网页中实现动画?

Animating an Array of Images in an Applet This is the simplest applet to animate an array of images.

import java.applet.*;

import java.awt.*;

public class AnimApplet extends

Applet implements Runnable {

Image[] images = new Image[2];

int frame = 0;

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) {

}

}

}

停止!
