Simulation Distance

What is Simulation Distance?​

From the Minecraft Wiki​

Simulation distance defines a square region of chunks around the player where entities are ticked. Using distance of 6 for instance, entities may move normally within a 13×13 chunk column around the player chunk. One more chunk out, within a one-chunk-thick square frame surrounding this region, redstone may run, fluid may flow, and crops may grow (subject to normal chunk ticking rules). Beyond that nothing moves or changes.

So why's it important?​

  • By default, changing view distance in this plugin also changes simulation distance to be the same. You can change this with the sync-simulation-distance option in config.yml.

  • If you set this to false, simulation distance will always be whatever it is set to in your server.properties file, regardless of view distance.

  • Entities, more complex redstone circuits and fluids will not be ticked if they are not in the simulation distance around the player.
