I want to create a map similar to how Mincraft and other related games do. I just haven't the faintest clue on how to do so. Can anyone point me to a decent tutorial or give me a decent run through? I program in java and use openGL. Thanks for any help.
Are you looking for something like this?
The article I mention in that answer is pretty good and talks about creating maps exactly like Minecraft. Using that article as a starter I was able to create maps like this for my game.
