Description

This mod is no longer supported or being updated.

It was a hack to fix mob performance issues in 1.18

~~It Shall Not Tick (ISNT) is a performance enhancing mod that limits entity ticking to within a configurable range of players.~~

~~If the entity is within the configured range of a player the entity will tick as normal, however if it is out of range the entity will not tick and will also not be rendered by the client.~~

~~This improves the server performance by allowing the server to not tick entities that the player will not be interacting with.~~

~~The mod also integrates with FTB Chunks by allowing entities in claimed chunks to continue ticking as normal.~~

~~You can also add entities to ignore in the config, by default the following entities are ignored and an example for a modpack is included in the comments of the config.~~

~~minecraft:wither~~
~~minecraft:phantom~~
~~minecraft:ender_dragon~~
~~minecraft:elder_guardian (as of 1.0.10)~~

~~This is mostly a fork of https://www.curseforge.com/minecraft/mc-mods/does-it-tick~~
