Mazing.cmd - A Visual Maze Generator for WinNT

#1 Post by CirothUngol » 27 Sep 2018 22:46

A while back I wrote a small script to replace the command line executable used by a fun little maze game posted here at DosTips. I continued toying with several of the maze generating and solving algorithms found at Think Labyrinth sticking with those that create perfect mazes, which elegantly have only one solution for any two chosen points on it's path, and any two points are always connected. I also designed the algorithms around the principle of visibility, so all of them operate on a single string variable containing the entire maze, making output/display/animation rather simple. I actually completed the algorithms about a year ago, but all of their many various options were completely random (hard-wired on purpose) and I wanted to implement some form of control structure before posting it. Over the past year I've tinkered with it a bit (adding more randomness and purely visual elements) and have usually had it running in the background just to catch any odd-case errors and iron-out any issues... besides, it's fun and interesting to watch if you dig mazes. ^_^

A few weeks ago I finally got around to implementing a menu and corralling most of the chaos into nice selectable options. It uses code page 437 and contains some unprintable characters, so careful which text editor you choose to manipulate it with (I use Notepad++). It will generate a log file in %~dp0, a couple of tiny files in %TEMP%, and will generate BG.EXE in %TEMP% if 'BG Color' is selected in the menu and it's not found in the system path (BG.EXE v3.9se is required for this option). Hopefully it runs as trouble free for others as it seems to on my Win7 x64 system. Special thanks to dBenham and his inimitable SNAKE.BAT for the batch example of a control element for interrupting the script, allowing the menu to be called at any time while running.

It's completely useless and an utter waste of time, so please download and give it a try!
As always, please post any errors or issues you may have.

Code: Select all

:: __________________________________________________________
:: A maze program written in native WinNT batch script that
:: includes several maze generation and solving algorithms as
:: well as a small plethora of options for console display,
:: stack size, stack orientation, node selection/direction
:: bias, entrance/exit points, color selection, and wall/box
:: characters, each with an automatic randomizer, and all of

:: Mazes are limited to a maximum practical string length of
:: 8186 characters. The maze dimensions will be automatically
:: increased/decreased if minimum/maximum size is exceeded.
:: Mazing operates using 100% WinNT batch script, but it will

::               Command Line / Mazing.ini File
:: __________________________________________________________
:: In addition to the menu, other User Variables are passed
:: by using either the Mazing.ini file or on the command line
:: by using the following syntax:
:: Mazing.cmd ["variable=value"] [variable:value] [...]
:: Several options for minimum/maximum columns/rows, lists
:: of characters for random walls/crumbs/colors, keys used by

:: A list of available user variables may be found under the

:: Maze Generators: perfect mazes, one path to any two points

::   Eller's Algorithm  - simplest and fastest of them all
:: Maze solvers: always find the 1 solution to perfect mazes
::   Don't Solve - only generate and convert mazes
::   Wall Follow - left or right hand on wall, depth-first
::   Dead Filler - remove dead-ends until path is revealed
::   Path Finder - flood maze until exit found, retrace path
:: Entrance/Exit: where to place the maze entrance and exit

Is very interesting.
I need choose manually Terminal font for a good display of the characters.
