Cara
membuat Game “Ular Terbang” menggunakan Netbeans
Untuk memenuhi tugas softskill pengantar
teknologi game.
Kami dari salah satu kelompok 3IA06

Project Ini kami ambil dan kembangkan sedikit
dari link:
terimakasih untuk author dari blog tersebut.
Sebelum masuk ke kodingan siapkan dulu
beberapa file dukungan seperti gambarnya dll. Bisa di download di link berikut
Langkah-Langkah Cara Membuat Game Ular Terbang
di Java
1. Buka Aplikasi Netbeand IDE di Launchpad
lalu klik Netbeans, atau bisa juga di finder, lalu pada folder Application >
Netbeans (ini untuk Sistem operasi Macintosh yang saya gunakan).
2. Setelah Netbeans terbuka, membuat project
baru dengan cara klik menu File > New Project atau bisa dengan tombol
Shift+Command+N pada keyboard.
3. Pada Kotak dialog choise Project Anda pilih
kategory Java dengan Tipe project Java Application. Setelah itu klik tombol
Next, seperti gambar di bawah.
4. Pada kotak dialog Name and Location,
centang pada Create main Class, dan set as main project. Lalu memberikan Nama
dengan game, setelah itu mengklik tombol finish.
5. Setelah itu pada project game yang ada di
sidebar netbeans, klik game > sources Package > game > game.java.
6. Kemudian mengetikkan Source program di
dalam editor netbeans, Source programnya adalah :
Game.java

Kemudian Selanjunyabuat class musuh.java

if (x < 0)
xArah = 1;
if (x > 630)

if (y > 470)
yArah = -1;
}
public void draw(Graphics g) {
Image musuh = new
ImageIcon(this.getClass().getResource("musuh.png")).getImage();
g.drawImage(musuh, x, y, null);
}
Rectangle getHitbox() {
return new Rectangle(x, y, 10, 10);
}
}
Untuk hasilnya akan seperti ini ketika di play
