Chunk Tracker
by Floonk
Chunk Tracker lists the loaded chunks around a player and lets them watch specific blocks, inspect block data and keep a block alert watchlist.
What it does
The mod shows which chunks are currently loaded and lets a player list the blocks in the chunk they stand in. Results can be ordered from the nearest entry to the farthest, or the reverse, in a screen that lists items held in containers, mobs set up in spawners, and other block entity information when the game makes it available. Chunk logs are saved in the Minecraft instance folder, so earlier scans remain available after the game closes.
A player can add or remove blocks from a watchlist and receive alerts when one of them is found. Renaming the current chunk or its biome is possible, and renamed chunks and biomes can be managed from a separate list. The author notes that a server-side installation is needed for the block data shown in the screens, similar to what Jade displays, and the mod is listed as Fabric only.
Chunk Tracker is published for Fabric across 11 release versions, 1.21.1 – 1.21.11, with 1.55 for 1.21.11 as the latest file. Only the player's game needs it, and servers run without it. The code is not open source, and the mod is released under All rights reserved.
