Hey there. I'm working on a plugin that will create machines. However, in order to create the machine, it has to be built with the correct schematics. For example, it has to be a 3x3 cube of Obsidian, with the center being an iron block, or a 5x5 cube with surface blocks being alternates of gold blocks or diamond blocks, etc. I already have a method for iterating through all of the blocks in the area I want to check, but how can I save these 'schematics' of sorts and cross check them?
