On Minecraft, how is it possible that during a map creation, you can just scramble letters, numbers and symbols as a seed and still have a random map as a result?

Question

My real question is, how is it possible on programming context?

Like, typing “dioasdjklasdknlvioj3e40435905$%” randomly on the seed input, start the map and have a still totally randomly generated world.

And by that, i actually mean how can that be possible if Minecraft wasn’t complex to program, as far as i know.

EDIT: Forgot to add, there is also a more than a sixtillion (Or even far, far more) of character combinations (Incluiding quantity of characters). All of them, if you change a single character in any place, generates you a random map. The slightlest change, and your map is completely different.

Where i am going is… how is it possible that such a small game like Minecraft could have an infinite number of randomly generated maps if it just weights a few Gigabytes (Or even Megabytes) on your PC?

The map is randomly generated. The seed is just an input to the random number generator. That’s not complicated at all, it’s trivial. Literally one or two lines of code.

Are you imagining that it somehow processes the text and makes a special world that represents something about that text? It doesn’t do that.
