This my Minecraft Terrain Generator. Pretty simple, and I am going to add more blocks soon. I could make this into a simple miner game with some tweaks. My first terrain generator. Blocks so far: Stone, Dirt Top, Dirt, Water, Tall grass, grass, granite, andesite, coal, diamond, emerald.
Sorry at the grass on top of the water, I'll fix that soon. Adding Trees in next update!
