Sourcecode Game HTML Javascript yang farazinux.com kali ini bagikan adalah source code game tetris. Sebuah game jadul alias kuno atau lawas namun tetap sangat mengasikkan untuk dimainkan dalam rangka mengusir gabut dan rasa bosan.
Game tetris adalah game lawas dan sangat populer. Cara bermainnya adalah anda akan diberikan batu bata dengan beberapa bentuk yang sangat khas. Tugas anda adalah menumpuk kotak atau batu bata tersebut dengan rapi, sehingga membentuk barisan batu bata yang tidak berlobang.
Main Game Tetris HTML Javascript
Berikut ini adalah game tetris yang dibuat dengan html dan javascript. Untuk memainkannya silahkan tekan tombol spasi pada keyboard anda. Sedangkan untuk berhenti sejenak anda dapat menekan tombol esc pada keyboard.
Beberapa tombol yang diperlukan untuk memainkan game Tetris ini adalah tombol spasi, esc dan tombol panah atas, bawah, kanan dan kiri keyboard. Adapun kegunaan masing-masing tombol tersebut adalah sebagai berikut:
- Tombol spasi untuk memulai aplikasi game tetris.
- Tombol esc untuk menjeda atau berhenti dari game tetris.
- Tombol panah ke atas untuk merotasi bentuk blok yang sedang berjalan.
- Tombol panah ke bawah untuk mempercepat blok turun ke bawah.
- Tombol panah ke kanan untuk menggeser blok yang sedang berjalan ke arah kanan.
- Tombol panah ke kiri untuk menggeser blok yang sedang berjalan ke arah kiri.
Untuk lebih jelasnya silahkan mainkan aplikasi game tetris berbasis html dan javascript di bawah ini.
