Here is some very old code, but it has all the basics. Just a warning it is not commented.
My current code is nothing like this, but you gotta start somewhere
forgot you need image for a texture. tiles 66x66 and 660W and 660H
edit I removed all the redundant loops for updating the block one at a time…Sometimes you can’t see the forrest because of the trees. Now I need to look into translate and related functions
I was killing the gpu for no reson thanks Ignatz
