PBO: osu! Catch The Beat Java Based (Final Project)

Untuk final project pemrograman berbasis objek, saya terinspirasi untuk membuat sebuah game setelah bermain game bernama osu!Catch the Beat. Saya ingin membuat game seperti itu namun menggunakan bahasa pemrograman java.

Potongan gambar dari osu! Catch the Beat yang asli:

Dengan pemrograman java seadanya saya berhasil membuat remake game ini namun dengan fitur yang lebih sedikit dari yang aslinya.

Program osu!ctb yang saya buat memiliki fitur basic yaitu menangkap buah yang jatuh dan permainan akan selesai setelah semua buah ditangkap.

Potongan gambar dari osu!ctb yang saya buat:

Class Schema untuk pemrograman osu!ctb ini adalah sebagai berikut:

• frame
•  class ini berfungsi untuk menggenerate frame yang digunakan untuk menjalankan permainan.
• background
• class ini merupakan motor utama game ini. class ini memiliki banyak fungsi salah satunya memanggil buah dan membuat ryu(alat penangkap buahnya). Selain itu background juga mengecek tabrakan antara ryu dan buah.
• control
• class ini berfungsi untuk mengatur gerakan dari ryu dan juga mengatur laju dari hasil inputan keyboard.
• buah
• class ini berfungsi untuk mengatur segala hal mengenai buah seperti laju turunnya buah dan menggenerate buahnya

PBO: Membuat Ticket Machine

     Hari ini saya belajar bagaimana cara membuat Ticket Machine di java menggunakan BlueJ.
Terlebih tadi sempat membahas mengenai:

• fields,
• constructors,
• parameters,
• methods,
• assignment and conditional statement.

Penjelasannya adalah sebagai berikut;

1. Fields
      Atau biasa kita kenal dengan sebutan variable berfungsi untuk menyimpan value.
 

2. Constructors
     Constructors memiliki fungsi untuk memberi inisiasi agar object itu bisa dijalankan.

3. Parameters
     Memiliki fungsi menyimpan value yang biasanya di deklarasikan di header. Dalam case ini "amount" merupakan parmeter.

4. Methods
     Methods merupakan fungsi yang bisa diberlakukan kepada object sesuai dengan classnya. Dalam case ini getPrice, getBalance, insertMoney merupakan method yang berlaku di class TicketMachine.

5. Assignment and Conditional Statement
     Assignment merupakan pemberian value kepada fields sedangkan conditional statement merupakan pernyataan yang akan menjalankan suatu fungsi ketika kondisi-kondisinya terpenuhi.

PBO: Main-main dengan Java

     Halo kawan-kawan. Hari ini saya mencoba bahasa pemrograman yang menurut saya cukup ciamik untuk dipelajari, yaitu java. Kalau ditanya kenapa memilih java mungkin karena java ini OOP dan juga sangat relevan untuk saat ini.
