Praktek 6 Game Pimpong : Final

Pada praktek sebelumnya praktek 5 Game Pimpong : User Input kita sudah menghasilkan sebuah game sederhana, berikutnya kita akan mencoba membuat score dari hasil permainan. Logikanya seperti ini : Jika kita tidak bisa menangkap bola maka score untuk HP bertambah 1 begitu juga sebaliknya. Berikut hasil akhir dari penambahan score:

Berikut penambahan script dari PongCanvas.java.
