Pada artikel kali ini saya akan berbagi contoh projek openGL dengan C++ menggunakan codeblock yaitu membuat trafic light jalanan 2 dimensi dengan fitur diantaranya event mouse untuk trafik dan event keyboard untuk mempercepat laju serta memberhentikan kendaraan plus translasi untuk menjalankan kendaraan tersebut. adapun hasil yang akan kita buat adalah sebagai berikut :
Adapun untuk membuat projek diatas yang perlu disiapkan antara lain :
- download openGL disini : View openGL
- setting codeblock dengan openGL caranya lihat disini: view
- buka codeblock dan buat projek baru caranya dapat dilihat disini : view
- copy semua sourcode yang tersedia di blog ini.

Features
dari projek diatas akan ada beberapa features yang akan ditampilkan diantaranya :- pilihan Lampu : dalam projek ini akan ada 3 tipe lampu yaitu lampu merah, hijau dan kuning. semua pilihan lampu akan dikendalikan oleh maouse.
- Kendaraan : didalam projek openGL ini juga akan disediakan 3 mobil yang akan dijalankan. kalau mau menambakan menjadi 5 mobil juga silahkan tapi dalam projek ini akan disedian cuma 3 mobil saja.
- opsi jalur : jalur dalam projek ini telah ditentukan oleh program. jadi sifat jalur static.
Interaksi Pengguna ke Hasil Program.
- pada saat pertama kali projek ini dijalankan maka langkah pertama yang kita lakukan adalah tekan enter untuk melihat panduannya kemudian enter kembali untuk menjalankan programnya.
- tombol H (help) digunakan untuk melihat opsi piliah panduan menjalankan animasi.
- tombol R digunakan untuk mengijinkan pergerakan lalu lintas dari kanan ke kiri.
- tombol L digunakan untuk mengijinkan pergerakan lalulintas dari kiri ke kanan.
- mouse kiri digunakan untuk menghentikan laju (Lampu merah).
- mouse kanan (klik tahan) digunakan untuk lampu kuning
- mouse kanan lepas digunakan untuk lampu hijau.
demikian sedikit sourcode yang saya bagikan berikut ini adalah gambar hasil akhir projek ini.
