Вкратце что делается. Левой кнопкой мыши добавляется Стартовая позиция. Правой кнопкой мыши добавляются блоки-препятствия. Средней кнопкой мыши добавляется Финиш и сразу запускается поиск пути.

 

Пока долго. Никто никуда не двигается по найденному пути. Но начало положено.

 

 

P.S.  Это поиск ортогональный. То есть в каждом следующем цикле проверяются 4 рядом стоящие клетки. Справа, слева, снизу, сверху.

Во вложении “png” с блоками и картой.
