Tugas saya kali ini adalah membuat game pong.
Pong adalah permainan video generasi pertama yang dirilis sebagai permainan arkade yang dioperasikan dengan koin yang dikembangkan oleh Atari Inc. pada tanggal 29 November 1972. Pong didasari dari permainan atau olahraga tenis meja (Ping pong), nama permainan ini berasal dari suara yang dihasilkan ketika memukul bola ping pong.Kata Pong telah didaftarkan sebagai merek dari Atari Interactive.
Pong adalah permainan video olah raga dua dimensi yang mensimulasikan sebuah permainan tenis meja. Sang pemain mengerakan sebuah bat yang bergerak naik-turun, permainan ini dapat dimainkan dengan komputer atau dua orang yang mengerakan bat
di sebelah kiri. Pemain memukul bola bolak-balik. Untuk memenangkan
permainan, sang pemain harus memukul bola tersebut sampai sang lawan
tidak bisa memukul bola tersebut.
