Tic Tac Toe di C#

[[[ SALAM ]]]

Salam hangat para blogger sekalian ! :)

Pada kesempatan kali ini saya aan menunjukkan sebuah program yang tidak biasa seperti sebelum nya,kali ini saya akan menunjukkan sebuah program Game sederhana yang bernama Tic Tac Toe,sebelum kita ke progam nya saya akan menjelaskan apa itu Tic Tac Toe...

1. Tentang Tic Tac Toe dan Sejarah nya

APA SIH TIC TAC TOE.?

     Sebelumnya saya ingin menjelaskan awal mula permainan Tic Tac Toe. Game Tic Tac Toe lebih dikenal sebagai permainan catur jawa jika di Indonesia. Bahkan dalam pengembangan permainan ini, Tic Tac Toe ada yang dalam bentuk tiga dimensi. Sebagian dari kita pasti mengenal permainan Tic Tac Toe. Permainan ini sangat unik karena menggunakan papan dengan grid 3×3 atau lebih yang dimainkan oleh dua orang pemain dan para pemain bermain dengan menggunakan bidak berbentuk “X” atau “O” membentuk satu barisan untuk memenangkan permainan. Permainan ini sangat diminati banyak orang di seluruh penjuruh dunia, bahkan dengan kepopulerannya di banyak negara memberikan nama unik seperti nama tit-tat-toe,Naughts and crosses,Exy-Ozys,Xsie-Osies,serta X’s and O’s.

SEJARAH

Menurut sejarah Tic Tac Toe berasal dari Kekaisaran Romawi sekitar abad pertama sebelum masehi. Masyarakat setempat menyebutnya Terni Lapili. Permainan ini sama seperti yang kita temukan di zaman sekarang yang dimainkan oleh dua orang  pemain dengan menggunakan tiga bidak, pemain harus membentuk satu barisan dengan bidak-bidak yang dimiiki di lembar kertas papirus. Namun ada informasi lain, menurut Claudia Zaslavsky dalam buku Tic Tac Toe: And Other Three-In-A Row Games from Ancient Egypt to the Modern Computer,  Tic-Tac-Toe berasal dari Mesir kuno. Namun bagaimana permainan ini mulai disebut dengan nama Tic Tac Toe? Pada tahun 1884, anak-anak bermain di sebuah batu tulis  dimana mereka menutup mata sambil mencoretkan batu dengan dua simbol "X" dan "O" membentuk satu barisan namun disertai suara tic dan tac dari anak-anak. Pada tahun 1952, Tic Tac Toe mulai marak diminati karena untuk pertama masuk ke dunia video game OXO (or Noughts and Crosses) untuk komputer EDSAC.  Pemain bisa memainkan Tic-Tac-Toe dengan melawan komputer bahkan dapat multyplay melawan manusia. Pada tahun 1975, Tic Tac Toe juga digunakan oleh siswa MIT  untuk menunjukkan kekuatan komputasi dari elemen Tinkertoy yang saat ini dipamerkan di Museum of Science, Boston .

Program Tic Tac Toe dengan C#

Oke,mungkin itu saja sekilas mengenai Tic Tac Toe,sekarang kita akan beralih ke program,tapi kita lihat dulu teori dasar nya...

 Teori Dasar

Control PictureBox digunakan untuk menampilkan gambar dan memanipulasinya. PictureBox dapat menangani berbagai macam format file gambar. Dalam praktikum ini kita menggunakan PNG. Untuk mengisi PictureBox dengan gambar, kita tinggal load gambarnya dengan menge-klik Properties Image-nya. Kemudian sesuaikan ukuran Width dan Height nya sehingga gambar tidak terpotong.

Jadi,untuk membuat program Tic Tac Toe kita akan lebih dominan menggunakan pictureBox.

Baiklah ,sekarang saya akan menunjukkan bagaimana program yang saya buat

 Dapat dilihat jika form program saya terdiri dari

1. 5 buah label
2. 2 buah groupbox
3. 2 buah button
4. 9 buah pircture box
5. 1 buah menu toolstrip(diatas form program)

dan saya akan menunjukkan sedikit pembuatan program nya..

Dan yang dibutuhkan adalah:

1. Komputer/Laptop
2. Kemauan
3. Visual Studio / C Sharp Develop

langkah langkah

 

1.Buka Visual Studio / C Sharp Develop

 

2.Seperti biasa,pilih WindowsFormApplication

 

3. ketika WindowsFormApllication yang akan kita edit sudah muncul,maka isilah form yang kosong dengan benda benda dari toolbox,semau anda yang penting disitu tersedia 9 picture box sebagai wadah menaruh gambar

seperti ini kira kira kita harus membuatnya

4.Kita harus memberi event klik pada tiap picture box,pada menu event pilih Click

5.Baiklah,dan mari kira lihat seluruh kodingan nya
