Usage is: + +dbox [-v|-i|-p|-P] file [file2 ...] + +-v - Be verbose. Print depth of search tree as searching is done. +-i - Interactive. Show an interactive version of the map once solved. +-P\-p - Play. Allows you to play the level. + +The file is a Sokoban level defined like this: + + +Level 1 + ### + #.# + # #### +###B B.# +#. B@### +####B# + #.# + ### + +The first line is the title of the level. + +The subsequent lines must all be of the same width and define the level. The +'#' character defines a wall. The 'B' character defines a box. The '.' +character defines a target square. The 'X' character can be used to define a +box already on a target square. + +If no interactive mode is used the level will be displayed along with the +route to solve it, e.g. + +Solving Level 1 + + ### + #.# + # #### +###B B.# +#. B@### +####B# + #.# + ### + +Route = 'DULLRUUDRR' + + +INTERACTIVE MODE KEYS +--------------------- + +In interactive mode the following keys can be used. + +P - Follow the solution path if one was found. +Backspace/B - Step back one move on the solution path. +Cursor Keys - Move. Note that the move will be blocked if the state of the + map is already known or moving a block will make the level + insoluble. +Q - Quit. + +Cursors to move, P to follow path, Q to quit, Backspace/B to step back |
