Source Code Program Java Animasi Frame Bitmap

Hello teman kali saya akan membagikan source code java untuk membuat animasi frame bitmap,

saat kita kecil mungkin pernah ada yg pernah main game pacman yg suka makan, yuk langsung aja 

kita mulai membuat code2nya sebagai berikut:

import java.awt.geom.AffineTransform;
import javax.imageio.ImageIO;
import java.net.URL;
import java.awt.*;
import javax.swing.*;
import java.io.*;

public class AnimatedFramesDemo extends JPanel {
   static final int CANVAS_WIDTH = 640;
   static final int CANVAS_HEIGHT = 480;
   public static final String TITLE = "Animated Frame Demo";
 
   private String[] imgFilenames = {
         "images/pacman_1.png", "images/pacman_2.png", "images/pacman_3.png"};
   private Image[] imgFrames;
   private int currentFrame = 0;
   private int frameRate = 5;
   private int imgWidth, imgHeight;
   private double x = 100.0, y = 80.0;
   private double speed = 8;          
   private double direction = 0;      
   private double rotationSpeed = 1;  
   private AffineTransform transform = new AffineTransform();
 
   public AnimatedFramesDemo() {
      loadImages(imgFilenames);
      Thread animationThread = new Thread () {
         public void run() {
            while (true) {
               update();
               repaint();
               try {
                  Thread.sleep(1000 / frameRate);
               } catch (InterruptedException ex) { }
            }
         }
      };
      animationThread.start();
      setPreferredSize(new Dimension(CANVAS_WIDTH, CANVAS_HEIGHT));
   }
 
   private void loadImages(String[] imgFileNames) {
      int numFrames = imgFileNames.length;
      imgFrames = new Image[numFrames];  
      URL imgUrl = null;
      for (int i = 0; i < numFrames; ++i) {
         imgUrl = getClass().getClassLoader().getResource(imgFileNames[i]);
         if (imgUrl == null) {
            System.err.println("Couldn't find file: " + imgFileNames[i]);
         } else {
            try {
               imgFrames[i] = ImageIO.read(imgUrl); 
            } catch (IOException ex) {
               ex.printStackTrace();
            }
         }
      }
      imgWidth = imgFrames[0].getWidth(null);
      imgHeight = imgFrames[0].getHeight(null);
   }
 
   public void update() {
      x += speed * Math.cos(Math.toRadians(direction));
      if (x >= CANVAS_WIDTH) {
         x -= CANVAS_WIDTH;
      } else if (x < 0) {
         x += CANVAS_WIDTH;
      }
      y += speed * Math.sin(Math.toRadians(direction));
      if (y >= CANVAS_HEIGHT) {
         y -= CANVAS_HEIGHT;
      } else if (y < 0) {
         y += CANVAS_HEIGHT;
      }
      direction += rotationSpeed;  
      if (direction >= 360) {
         direction -= 360;
      } else if (direction < 0) {
         direction += 360;
      }
      ++currentFrame; 
      if (currentFrame >= imgFrames.length) {
         currentFrame = 0;
      }
   }
 
   public void paintComponent(Graphics g) {
      super.paintComponent(g);
      setBackground(Color.WHITE);
      Graphics2D g2d = (Graphics2D) g;
      transform.setToIdentity();
      transform.translate(x - imgWidth / 2, y - imgHeight / 2);
      transform.rotate(Math.toRadians(direction),
            imgWidth / 2, imgHeight / 2);
      g2d.drawImage(imgFrames[currentFrame], transform, null);
   }
 
   public static void main(String[] args) {
      SwingUtilities.invokeLater(new Runnable() {
         public void run() {
            JFrame frame = new JFrame(TITLE);
            frame.setContentPane(new AnimatedFramesDemo());
            frame.pack();
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.setLocationRelativeTo(null);
            frame.setVisible(true);
         }
      });
   }
}

Berikut ini file-file bitmap yang digunakan progam tersebut :

 Keterangan koding yg berwarna merah adalah nama file image pacman gunakan 3 buah file image
silakan mencoba
