Loaded Chunks

Loaded Chunks/Simulated Chunks

Loaded Chunks also known as simulated chunks are the chunks that anything can normally process in. These chunks only occur around a player or created with the use of /tickingarea or Add-ons. These chunks are what players will spend their time interacting with a majority of the time.

Buffer Chunks

Around every loaded chunk is a buffer of unloaded chunks this is to improve load times and general stability of the game.

Loaded Area Size

The size of the area of loaded chunks around a player is dependent on the simulation distance setting in the world settings and it comes in four different sizes 4 chunks, 6 chunks, 8 chunks, and 12 chunks. These sizes are not radii as you may be inclined to believe but instead follow taxicab geometry. 

Functions

Chunks that are loaded/simulated are able to process anything you will find in normal gameplay such as: 

  • Entity AI/Events
  • block ticking
  • random ticks

It is important to note that events can happen outside of these loaded chunks. See unloaded chunks for more information.
