About this Mod

Copper Chunk Loader

Chunk Loader

Chunk loader data pack that aims to be vanilla survival friendly and to find more uses for copper.
This data pack is designed to be as simple as possible, so you can just drop it in your datapacks folder and start using it right away.
No need to set up some fancy stuff.


📀 Features

Chunk Loader

Chunk Loader is a block that keep chunks around it always active even when the player leaves the area.

💡 Notice

Due to technical reasons, this chunk loader CANNOT simulate player's chunk tick. This means mob spawning mechanics WON'T WORK!

BUT you can still use this for anything that doesn't require player's chunk tick, such as Mob ticking related farm (for example Iron Golem Farm still works), Crops growing*, Cauldrons filling*, Redstone contraptions, Furnace burning, Duplication, etc.

For more information on this topic, please see Chunk tick.

* 1.21.5+ only, any version below 1.21.5 still require a player to be nearby.

Tiers



Chunk Loader comes with 5 tiers, Copper, Iron, Gold, Diamond, and Netherite.
Each tier increases the range of active chunk loading, with higher tiers covering more chunks.

Here is the list of tiers with their range:
  • Copper: 3x3 Chunks
  • Iron: 5x5 Chunks
  • Gold: 7x7 Chunks
  • Diamond: 9x9 Chunks
  • Netherite: 11x11 Chunks

How to use?

Simple! Just place it. I've seen a lot of chunk loader data packs that require you to set up some stuff for the chunk loader to be activated. And I'm here to solve this problem by making it as simple as possible.
