Proses menciptakan labirin yang sebenarnya menggunakan algoritma pencarian kedalaman-pertama , tetapi dengan pendekatan berulang. Begini cara kerjanya.
Kita mulai dengan array int
nilai 2D , setiap elemen menjadi -1. Elemen acak dengan indeks genap dipilih, dan nilainya menjadi 0:
-1 -1 -1 -1 -1 -1 0 -1 -1
-1 -1 -1 -1 -1 -1 -1 -1 -1
-1 -1 -1 -1 -1 -1 -1 -1 -1
-1 -1 -1 -1 -1 -1 -1 -1 -1
-1 -1 -1 -1 -1 -1 -1 -1 -1
-1 -1 -1 -1 -1 -1 -1 -1 -1
-1 -1 -1 -1 -1 -1 -1 -1 -1
-1 -1 -1 -1 -1 -1 -1 -1 -1
-1 -1 -1 -1 -1 -1 -1 -1 -1
Kemudian program memasuki loop, memeriksa sel yang tersedia sampai mencapai keadaan di mana tidak ada sel yang tersedia. Ini bisa terjadi beberapa kali, dan saat itu mulai mundur. Pada saat ini semua 0s yang muncul menjadi 1s. Juga selama waktu ini adalah ketika menentukan apakah jalan keluar harus ditempatkan di lokasi itu. Jadi pada akhirnya, array bisa terlihat seperti ini:
0 0 0 0 0 0 1 1 1
0 -1 -1 -1 -1 -1 0 -1 1
0 0 0 0 0 -1 0 -1 1
-1 -1 -1 -1 -1 -1 0 -1 1
0 0 0 0 0 0 0 -1 1
0 -1 -1 -1 -1 -1 -1 -1 1
0 -1 1 1 1 1 1 -1 1
0 -1 1 -1 1 -1 -1 -1 1
0 -1 1 -1 1 1 1 1 1
Ketika ada jumlah 1s atau 0s yang telah ditentukan pada titik-titik tertentu dalam array, loop keluar. Kemudian, menggunakan array, labirin yang dihasilkan digambar:
Sangat mudah untuk melihat bahwa -1s dalam array mewakili dinding, dan 0s dan 1s adalah koridor. Barang-barang didistribusikan secara acak di seluruh labirin. Elips merah adalah "pemain" yang Anda kontrol.
Labirin dibungkus dalam panel gulir untuk kenyamanan sehingga jika ukurannya melebihi ukuran maksimum bingkai Anda dapat menggulir untuk melihat sisa labirin.
Saya akan mengatakan satu-satunya masalah dengan ini adalah bagaimana akhir permainan dilakukan. Saya memikirkan beberapa cara untuk melakukannya, tetapi saya akhirnya menggunakan hard-coding semuanya. Saya terbuka untuk saran tentang bagaimana hal itu bisa dilakukan.
