Does It Tick?
by Txni
Does It Tick? is a server-side optimization mod that stops entities far from players from ticking, and lets claimed chunks keep them active.
What it does
Entities in a loaded chunk normally tick every game tick even when no player is nearby. This mod turns that ticking off for entities that are not close to a player, which lowers the work a server performs. The author notes that the change rarely affects gameplay, though it does break some expected behaviour of AFK farms.
Claims made with FTB Chunks are recognised by the mod, so chunks inside a claim can keep their entities ticking while no one is nearby. A long configuration list lets server owners exclude specific entity types, and a default whitelist already covers entities such as the Ender Dragon and Ghast that need to tick for gameplay reasons. Modded entities that freeze when far away can be reported through the project's GitHub issue tracker.
Installation needs Chunk Activity Tracker, Fabric API and TxniLib on the Fabric loader, and Chunk Activity Tracker and TxniLib on Forge and NeoForge. Players can join without installing it, since the mod runs on the server alone. Files target 1.20 – 1.21.1 for Fabric, Forge and NeoForge, and the code is released under the GNU Lesser General Public License v3.0 only, so it is open source.
Key features
Entity ticking control
Entities far from players stop ticking, which reduces the load a server carries in large worlds.
Claim integration
Chunks claimed through FTB Chunks keep their entities ticking while the owner is away.
Configurable whitelist
Specific entity types can be excluded from the optimization, and a default whitelist protects entities needed for gameplay.
Public source and issue tracker
The source code and an issue tracker are publicly available for reporting modded entities that freeze.
