9.1 Random Maze

9.1.1 Konsep

Random Maze merupakan permainan yang mengedepankan strategi untuk mencari jalan keluar dengan cepat, tanpa tersesat pada jalan yang buntu. Pertama ketika aplikasi dijalankan, maka map dari daerah pencarian akan dirandom dengan ukuran tertentu. Pada kondisi awal, letak dari agen berada di posisi start, dan tujuan akhirnya adalah posisi goal. Untuk menggerakkan agen (yang berbentuk segitiga), tombol control dibagian kanan bawah dapat digunakan untuk melakukan hal tersebut.

9.1.2 Tampilan Implementasi

Aplikasi ini mengimplementasikan primitive object, texture map-ping, pencahayaan dengan tampilan objek garis, segitiga, segiempat, bola, counter pantulan bola, serta dengan tombol control yang diberikan texture tertentu untuk memindahkan objek (agen) dalam mencari solusi pencarian jalan keluar. Berikut ini beberapa visualisasi dari permainan Random Maze, mulai dari adanya background (gambar, fractal), tombol control, animasi objek bergerak, efek pencahayaan, sampai pada log posisi track sentuhan tangan pada layar.
