Cara Membuat Game Menggunakan Notepad

Kebanyakan orang menganggap jika membuat game itu sangat susah, tetapi tanpa kamu sadari game bisa dibuat dengan menggunakan apa saja dan bahkan aplikasi yang kurang masuk akal, contohnya seperti pada artikel ini yaitu cara membuat game sederhana alias game Snake Xenzia hanya dengan menggunakan Notepad.

Notepad biasanya digunakan hanya untuk menyimpan catatan kecil, tetapi tanpa kamu sadari para pengembang sebuah game bisa menciptakan sebuah game sederhana hanya dengan menggunakan Notepad tersebut, buat kamu yang penasaran bagaimana cara membuat game menggunakan notepad, berikut tutorialnya.

1. Buka aplikasi notepad pada PC kamu.

2. Lalu salin kode di bawah ini atau bisa lihat di pastebin

3. Tempel pada notepad.

4. Lalu Save dengan cara klik tombol file → Save, atau dengan menekan Ctrl + S pada keyboard.

5. Lalu atur save as type menjadi All Files dan ubah namanya menjadi ular.bat, pastikan ditambah huruf .bat pada akhiran nama file, dan klik tombol save.

6. Lalu buka file ular.bat tersebut dan pilih level sesuai yang kamu inginkan dengan cara menekan nomor pada keyboard sesuai dengan pilihan level pada aplikasi ular.bat.

7. Selesai, selamat bermain. Kontrol pergerakan ular pada game ini menggunakan tombol W (Atas) A (Kiri) S (Bawah) D (Kanan).

Pada game ini terkadang suka mengalami lagging pada saat bermain, dan biasanya lagging di dapat saat baru pertama kali bermain, tapi jika terus dimainkan tidak akan ada lagging lagi.

Game ini tidak perlu menggunakan koneksi internet.
