How does Minecraft build its worlds?
When you create a new world in Minecraft, the game will make something totally unique. No one will have ever played in a world like yours. But how does the game do this? How does it decide where to put mountains, trees, and lakes?
It’s all down to something called procedural generation. It’s a little bit like making something at random, but with rules. When things are chosen at random, there can be problems, like putting cats in the sea or building a tree in a cloud. But if there are rules – trees MUST grow on the ground, cats CAN NOT swim – then the world can be made both unique but logical.
To get a better idea, watch this great episode of Game/Show, which explains how procedural generation in Minecraft works.
