I'm unable to create a simple maze following the instructions on the wiki and the one outdated video I could find on youtube. I didn't watch the Minecraft Alpha video linked to on the "how to build a maze" guide on the wiki since it is muted due to copyright infringement, so if there was any vital information in threre, please do tell.
The maze doesn't generate. I did all the Trial & Error I could think of and did it again after you fixed the ID bug I reported yesterday. Would you please confirm that it is possible to create working mazes in v1.2.2 or maybe even take look at my attempt at a simple hedge maze?

You're missing 3 things.

Firstly, your maze needs an entry or exit - a point from which to start the maze.

Secondly, your components all have room size 0 to 3. Every one of them, as they are base components, need to be size 1, 1, 1 (areas 0, 0, 0 to 0, 0, 0). I get why you would get this wrong, I probably need to explain this better in the tutorial.

Thirdly, all your components are lacking their exits. Otherwise the algorithm doesn't know how to connect them.

I recommend looking at the StoneMaze components if you need examples of how it works.

(I'm closing this because it's not an issue per se. If you have more questions feel free to ask.)

I got it now, thanks!
