Open Source Chunk Loaders

Open Source Chunk Loaders is a free addon that adds chunk loaders to Minecraft Bedrock Edition. These can be used for a variety of purposes, like loading farms that don't require a player to be nearby to work, like crop farms. Unlike the existing /tickingarea command, Open Source Chunk Loaders use an entity with a minecraft:tick_world component to keep chunks loaded. Within reason, unlimited chunk loaders can be added, from a 2 chunk radius, to a 6 chunk radius. This will NOT work as a player, farms that require a player nearby like Iron Golem farms or spawner-based farms, will not work.

To get the chunk loader, you will need a Nether Star and a Lodestone. Craft the two together, it doesn't matter how you position them. In return, you will get a Chunk Loader block.

You can also obtain this by inputting /give @s cda001:chunk_loader_block. This block will cycle through many different states of chunk loading, anywhere from 2-6 chunks.

Place this block down. It is not currently loading any chunks. To do so, step on top of the block. It will become an entity.

Right now, it is still not loading chunks. To start loading chunks, interact with this block. This varies based on device, it is basically what you would do to fish. As you continue to interact, you will cycle through all the different chunk loading radii:

There you go! These chunks are now being loaded. To pick these up, sneak and then interact.


Tiny Technical Bits

The textures are designed so as to visualize the area loaded. Everything in black is not loaded. Everything inside of the green (including the green) is loaded. The blue represents the chunk in which this chunk loader is in.

There are a couple of helpful resource packs that may help with chunks, those being MaddHatter's, FoxyNoTail's, and WinEpicFin's.

As stated above, this will NOT work for farms that require an active player, like iron farms or spawner-based farms.

This pack is open source, meaning anyone may contribute and/or remix and build upon this add-on.

Warning: Do NOT add too many of these, it will lag your game.

I go into some technical detail in this video as well:


Finally, enjoy! Let me know if you have any issues as well!

Select version for changelog:

  • Updated version number to match with MCPEDL (assuming I remember file verification)
  • Fixed an issue preventing chunk loaders from being summoned when stepping on the block, in the nether/end (#82)


To Download:

1. Download the pack at the given link

2. Import it
2.5. If you are unable to import it with a tap/double click, rename the file from a .mcaddon file extension to a .zip file extension. Afterwards, unzip the folder and move the behavior pack to the behavior_packs folder and the resource pack to the resource_packs folder of the com.mojang folder

3. Apply it to your worlds

4. Enjoy!

Very helpful especially for command blocks when using in creative :) Also brings more use to nether resources as they're need to craft this. The only one of three mods with this concept on this site to work.
This man is an absolute genius
it doesnt work on 1.17 and up. updates?
Annoying to see the label "Chunk loader" through walls and floors especially if you put a few in a line

It doesnt say the chunk load distance in the chat like in your video, probably because im not using command blocks to set it, so a bit harder to figure out how far it goes but not that bad to guess from the texture of the block
If you want, you can modify the functions/cda001/chunk_loader.mcfunction file and change line 1 to remove the last part when it said "Chunk Loader". This will remove the name.

Like I put in earlier in the description of this, it would also be very helpful if you were to download a chunk borders pack, that plus the textures of the chunk loader should help you to get an idea.

Really appreciate this feedback btw, thanks!
