Area Light Up
Area Light Up places torches automatically in dark areas around a player, which keeps mobs from spawning there.
What it does
Area Light Up scans a radius around the player and places torches in dark spots that mob spawning could use. It builds a grid of positions 12 blocks apart, because a torch's light reaches 14 blocks, so the grid covers the area. After the grid is complete, a cleanup pass looks for any dark spots that were missed. Placement runs at one torch per tick, about 10 torches per second, so the work does not cause server lag. Progress is reported every 50 torches.
Before placing anything, a preview scan shows how many torches are needed and how many stacks that makes, for example 3840 torches in 60 stacks. A comparison against the survival inventory shows whether the player already has enough and lists any crafting materials still missing. Placement begins only when START is clicked, and cancelling stops the job without placing anything.
The mod is a Fabric mod for Minecraft 1.21.11 and is open source under the MIT License. Server owners install it, and players connect with no copy of their own. Its source code and issue tracker are public.
Key features
Automatic torch placement
Torches go down in dark spots within a set radius around the player, where they prevent mob spawning.
Grid-based layout
Positions are laid out 12 blocks apart, so the light of each torch overlaps the next and leaves few gaps.
Preview scan
Before any torch is placed, the scan reports the torch count, the stack count and the materials that are missing.
Survival inventory check
The preview compares the required torches with the player's survival inventory and shows any shortfall.
Cleanup pass
After the grid is finished, a second scan looks for dark spots the grid missed and places torches there.
