Maze - A plugin for generating mazes created by Panda843/EschieEsh
Usage : /maze <size_x> <size_z> <walls_height> <wall block id[:block meta]>
Permission : maze.cmd | Default - OP
IMPORTANT!
<size_x> and <size_z> must both be odd numbers and must be in range of min_size_x/max_size_x and min_size_z/max_size_z, a range which you can edit in the config.yml
<wall_height> must be in range of min_walls_height/max_walls_height, a range which you can edit in the config.yml (A config.yml is created directly after enabling the plugin)
I think this goes without saying but the must be an id of a block, not item or something. Highly not recommended to choose ids of Saplings, Flowers, Water and Lava as that will not be a proper maze and it might cause heavy on your server so you have been warned. If you do not know ids of blocks and items, visit this link : http://minecraft-ids.grahamedgecombe.com/
It is highly recommended to generate the maze on a flat area or in the air but keep in mind that only the walls of the maze are generated so if you want a floor or a roof, you will have to build it yourself, hi-hi-hi. (In case the maze is gigantic, use some kind of a WorldEdit to help yourself).
Here is an example :
