El proceso de creación del laberinto real utiliza el algoritmo de búsqueda de profundidad primero , pero con un enfoque iterativo. Así es como funciona.
Comenzamos con una matriz 2D de int
valores, cada elemento es un -1. Se elige un elemento aleatorio con índices pares, y su valor se convierte en 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
Luego, el programa entra en un bucle, buscando celdas disponibles hasta que alcanza un estado en el que no hay celdas disponibles. Esto puede suceder varias veces y es cuando comienza a retroceder. En este momento, todos los 0 que se encuentran se convierten en 1. También durante este tiempo es cuando determina si se debe colocar una salida en esa ubicación. Entonces, al final de todo, la matriz podría verse así:
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
Cuando hay un número predeterminado de 1s o 0s en ciertos puntos de la matriz, el ciclo sale. Luego, usando la matriz, se dibuja el laberinto resultante:
Es fácil ver que los -1 en la matriz representan paredes, y los 0 y 1 son corredores. Los artículos se distribuyen al azar en todo el laberinto. La elipse roja es el "jugador" que controlas.
El laberinto está envuelto en un panel de desplazamiento para mayor comodidad, de modo que si el tamaño excede el tamaño máximo del marco, puede desplazarse para ver el resto del laberinto.
Yo diría que el único problema con esto es cómo se lleva a cabo el final del juego. Pensé en varias maneras de hacerlo, pero terminé recurriendo a codificarlo todo. Estoy abierto a sugerencias sobre cómo se puede hacer.
