Akhirnya setelah sekian lama tidak “ngoprek” blog,saya luncurkan posting terbaru saya…(Lebai mode on)
Di bawah ini merupakan script java untuk membuat game mobile “kacangan”..
Tapi silahkan dicoba..
^^
//Simpan source code dibawah ini sesuai dengan nama classnya(CanvasPong.java)

O ya hampir lupa..
Ini adalah gambar dari bola dan padnya..
bola
Lalu ini padnya..
pad
Nah ni buat midletnya..
(Simpan dengan nama Pong.java)
import javax.microedition.lcdui.Display;
import javax.microedition.midlet.MIDlet;
public class Pong extends MIDlet {
private static CanvasPong canvas;
public Pong() {
canvas = new CanvasPong();
}
public void startApp() {
Display display = Display.getDisplay(this);
canvas.start();
display.setCurrent(canvas);
}
public void pauseApp() {
}
public void destroyApp(boolean unconditional) {
}
}
Maaf klu tampilan blognya masih acak”an…
