Minecraft's Creeper Was A Coding Mistake
In 2009, Notch swapped two numbers while coding a pig, and accidentally created Minecraft's creeper.
The script
Minecraft's most famous monster was never supposed to exist.
In two thousand nine, Notch was building a pig.
He had no three D software, so he typed every shape into the code.
But he swapped two numbers... the pig's length, and its height.
So instead of a long pig, he got a tall, stiff block... on four tiny feet.
It looked so creepy, he kept it.
You see, he turned it green, gave it a sad face, and one job... sneak up on players, and EXPLODE.
It became the face of the whole game.
So technically...
The facts, checked
- The model began as the pig. Notch built models in code, with no modelling program, and accidentally made it "tall instead of long… a tall thing with four little feet". He kept it as a creepy creature.
- The model appeared in a pre-alpha update on 20 August 2009. Creepers arrived as a mob on 1 September 2009.
- The creeper is green, sneaks up on players, hisses and explodes. It became Minecraft's best-known icon.
