Operasi Aritmetika untuk Variable
Pada pembahasan sebelumnya, kita telah mengenal dasar-dasar serta fungsi dari variable dalam pembuatan game. Pada pembahasan kali ini, kita akan mempelajari mengenai bagaimana cara memanipulasi nilai-nilai dari sebuah variable dengan menggunakan operasi Aritmetika.
Cara menambah nilai variable
Seperti yang telah kita ketahui, bahwa bila kita membuat variable seperti dibawah ini :
score = 0
Maka, artinya bahwa kita telah membuat sebuah variable yang bernama score dan men-setting nilainya sama dengan (nol).

Nah, sekarang pertanyaannya bagaimana cara agar kita bisa menambah nilai dari variable score tersebut?
Untuk menambah nilai dari suatu variable kita bisa menggunakan operasi tambah ( + ).

Bentuk Umum dari Operasi pertambahan adalah :
- - - - - - - - - - -
variable +=nilai
- - - - - - - - - - -
Contoh :
score +=100
Artinya : kita menambah nilai dari variable score sebesar 100 ( Seratus).
Sehingga dengan menambahkan script ini, variable score yang asalnya mempunyai nilai sama dengan 0 (nol), menjadi bertambah sebesar 100 (seratus).

Cara mengurangi nilai variable
Caranya hampir sama seperti cara diatas, hanya saja kali ini kita menggunakan operasi pengurangan ( - )

Bentuk Umum dari Operasi pengurangan adalah :
- - - - - - - - - - -
variable -=nilai
- - - - - - - - - - -
Contoh :
score -=50
Artinya : kita mengurangi nilai dari variable score sebesar 50 ( Lima puluh).
Sehingga dengan menambahkan script ini, variable score yang asalnya mempunyai nilai sama dengan 0 (nol), menjadi berkurang sebesar 50 (Lima puluh).

Operasi Perkalian dan Pembagian untuk variable
Caranya juga sama seperti cara diatas, hanya saja untuk perkalian rumusnya adalah :

Bentuk Umum dari Operasi perkalian adalah :
- - - - - - - - - - -
variable *=nilai
- - - - - - - - - - -

Sedangkan, Bentuk Umum dari Operasi pembagian adalah :
- - - - - - - - - - -
variable /=nilai
- - - - - - - - - - -
