I stumbled upon this guy that implements it by having an array that has float values for the block's corners (not blocks themselves), therefore the array is bigger than if it just stored the blocks themselves (link to his code here). My question is if there's a way to rewrite it so it uses the array I'm using, that contains the blocks themselves, instead of the slightly longer array he's using with the block corners. I'm quite confused on how to rewrite it as the way he checks is by checking if the current corner value in the world is above a certain threshold (or so I understand), which doesn't sound like something that supports holes for example, or caves? I am aware that it requires maybe just 1 function to be rewritten and that is the getconfiguration() function to instead check surrounding blocks right? But how would I do that? What would be the checks?
