Is it possible to extend the block metadata by using tile entities? And if it is where would I be able to find out how to do it?
EDIT: Been doing some reading on tile entities and it looks like I don't want to do this because it would take more and more memory to do something like this so I am going to stick with the standard 0-15 block meta (for now)
Although I would still like to know how to do this if just in case the need to do this ever arises...
