TUTORIAL
PEMBUATAN GAME J2ME
A.MEmbuat
Game Dengan NetBeans
1.kIta
Harus Menyiapkan Gambar .png Terlebih Dahulu
2.Setelah disiapkan,Kita mulai
membuatnya dengan Netbean;
Step 1
masuk pada aplikasi NetBeans, selanjutnya pilih New Project akan muncul
tampilan seperti ini, lalu next.
Kita Pilih JavaME lalu Next.
Step
2 isi nama Project sesuai keinginan, contoh Muhammad_Muttaqien, lalu next.
Step
3 Kita plih MIDP-2.0 lalu finish.
Step
4 setelah finish akan tampil seperti gambar dibawah ini, klik kanan pada Soucre
Packages, pilih New lalu pilih MIDlet….
Step
5 beri nama Class, missal MIDlet, kemudian finish.
Lalu kiya isikan scrip ddlm MIDlet

/**

public
class Midlet extends MIDlet {
Game x;
MenuUtama mu;
Instruksi i;
Tentang t;
Display d = Display.getDisplay(this);
public Midlet() {
mainMenu();
}
public void startApp() {
}
public void pauseApp() {
}
public void destroyApp(boolean
unconditional) {
}
public void kosongkan() {
if(x != null){
x.stop();
x = null;
}
if(i != null){
i.stop();
i = null;
}
if(mu != null){
mu.stop();
mu = null;
}
if(t != null){
t.stop();
t = null;
}
}
public void mainMenu(){
kosongkan();
mu = new MenuUtama(this);
mu.start();
d.setCurrent(mu);
}
public void mainkan(){
kosongkan();
x = new Game(this);
x.start();
d.setCurrent(x);
}
public void instruksi(){
kosongkan();
i = new Instruksi(this);
i.start();
d.setCurrent(i);
}
public void quit() {
destroyApp(true);
notifyDestroyed();
}
void tentang() {
kosongkan();
t = new Tentang(this);
t.start();
d.setCurrent(t);
}
}
3.Kemudian kita buat java class baru,
kita ikuti langkah berikut.
Lalu ketikan koding berikut:

5.Setelah Semua
sudah Diisi script,kita buat Package Baru,lalu Copykan Gambar Yang Sudah
Disiapkan tadi di awal pembuatan:
Stelah
di copy hasilnya seperti ini:
6.Setelah itu kita juga menambahkan
suara didalam game tersebut,langkahnya sama buat package baru dengan nama
suara.
Coba di running Gamenya.Maka Hasilnya
sebagai berikut:
