Copper Chunk Loader
by CrazyWichGG
Copper Chunk Loader adds a copper block, with four upgrade tiers, that keeps nearby chunks loaded even when no player is in the area.
What it does
Placing a Chunk Loader keeps the chunks around it active while players are away, so crops keep growing, furnaces keep burning and contraptions keep running. Mob spawning mechanics do not work inside those chunks, because the block cannot simulate the player's chunk tick. Farms such as an Iron Golem farm still work, as do cauldrons filling and redstone circuits.
The mod is a data pack, so it needs no extra mod loader to run. Files are published for Fabric, Forge, NeoForge and Quilt, as well as the data pack form. Server owners install it on the server; players need nothing, because only the server needs it. Versions from 1.21.2 onward need no player nearby, while 1.21.5 and later are the only builds where the loader works without a player in range.
The data pack is licensed under Creative Commons Attribution Non Commercial Share Alike 4.0, and it is not open source. Source code and an issue tracker are linked from the project page.
Key features
Copper chunk loader block
A copper block keeps its surrounding chunks loaded and active without any setup beyond placing it.
Five tiers
The loader comes in copper, iron, gold, diamond and netherite tiers, and each higher tier covers a larger area.
Chunk range from 3x3 to 11x11
Ranges step from 3x3 to 5x5, 7x7, 9x9 and 11x11 chunks, with the tier setting how many chunks are kept active.
Vanilla survival friendly
The data pack uses only vanilla crafting and items, so it adds no new mechanics beyond the loader itself.
Chunk preview on hold
Holding the item shows which chunks a placed Chunk Loader currently affects.
