In a remarkable feat of digital endurance, a custom-built Minecraft simulation has successfully defeated the Ender Dragon, the game's final boss, without any player input. This extraordinary accomplishment, however, required nearly two billion simulated years to complete. The discovery was made by YouTuber RedLogic, who engineered a simulation to explore the possibility of a playerless victory.
To achieve this, RedLogic employed a Monte Carlo simulation method. This technique allowed for the compression of billions of in-game 'ticks' into sampled waiting times, meticulously tracking rare events and the necessary physical resources that could either advance or hinder the simulation's progress toward completing the game. The goal was to determine if Minecraft's internal mechanics could, over an extended period, replicate the actions a player would take to win.
A critical aspect of the simulation was finding an appropriate Minecraft world seed. This seed needed to possess sufficient resources and a naturally occurring Ender Portal, both essential for the game's progression to the final boss. After running a preliminary simulation to identify the perfect world, RedLogic set the main simulation in motion.
The journey to the Ender Dragon was exceptionally slow, with tens of thousands to millions of years passing between significant milestones. The simulation documented that it took approximately 35,510 years for endermen to locate and utilize the portal to reach the End dimension. Once there, the simulation had to wait for endermen to gather the means to destroy the End Crystals, which protect the dragon.
Due to the random nature of NPC behavior, this process was protracted, spanning millions of years. A pivotal moment occurred after three million simulated years when a snow golem's projectile inadvertently destroyed one of the End Crystals. This event highlighted the reliance on chance and environmental interactions within the simulation. The process of destroying the remaining nine End Crystals and then damaging the Ender Dragon to defeat it required a repetition of such fortuitous events and the introduction of creepers to inflict damage on the dragon.
Ultimately, the entire simulation concluded after 1.97 billion years. While this method is considerably slower than a human player's experience, the successful completion underscores the depth and potential of Minecraft's emergent gameplay. The enduring nature of Minecraft, now 17 years old, continues to demonstrate that remarkable possibilities can arise within its virtual world, even allowing for features like players being able to sit down in recent updates.
