Langkah-Langkah Cara Membuat Game pingpong di Java
*Saya membuat tutorial ini berdasarkan sistem operasi Macintosh yang saya gunakan.
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 Pimpong, setelah itu mengklik tombol finish.
5. Setelah itu pada project Pimpong yang ada di sidebar netbeans, klik Pimpong > sources Package > pimpong > Pimpong.java.
6. Kemudian mengetikkan Source program di dalam editor netbeans, Source programnya adalah :
package pingpong;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.Rectangle;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

this.Ulang();
}
}
public void Ulang() {
requestFocus(true);

for (int i = 0; i < Brick.length; i++) {
Brick[i] = new Rectangle(brickx, bricky, 31, 11);
if (i == 5) {
brickx = 70;
bricky = 62;
}
if (i == 9) {
brickx = 100;
bricky = 74;
}
brickx += 31;
}
repaint();
}
}
7. Setelah mengetik dan memeriksa hingga tidak terjadinya error, maka jalankan program dengan cara klik kanan pada pimpong.java lalu klik Run file, atau bisa dengan menekan shift + F6 pada keyboard.
8. lalu, setelah program berhasil di compile dan di run, maka akan muncul jendela game seperti pada gambar di bawah ini jika anda kalah maka akan muncul pesan seperti di gambar.
