Light Level Simple
by nomad_dev
Light Level Simple is a client-side overlay that shows light level numbers on blocks, including where mobs can spawn.
What it does
The overlay draws block light values and, when enabled, a daylight row above them, so a player can see which spots are safe and which are unsafe for hostile spawns. Colors mark the safe and unsafe areas, and custom colors can be set for each group, with an optional separate color for the daylight value. Light values can differ by dimension, and the numbers can be scaled independently for block light and daylight.
The mod draws only on the player's own screen. Players who want to plan a base or a mob trap can change how far around the player the numbers appear through an adjustable chunk range. Required dependencies are Architectury API, Cloth Config API and Fabric API, and the mod is available for Fabric and NeoForge. Light Level Simple is client-side only, so servers do not need it, and it is released under All rights reserved, so the code is not open source.
Key features
Block light overlay
Numbers show the block light value on each block, so spawn-safe spots are visible in the world.
Daylight row
An optional row above the block values displays the daylight level for the same position.
Safe and unsafe colors
Each area is colored by whether it is safe or unsafe, and the colors can be replaced with custom values.
Dimension-specific levels
Light levels are tracked separately for each dimension, so the overlay matches the rules of the world the player is in.
Adjustable chunk range
The distance around the player where numbers appear can be changed to suit the view.
Independent scaling
Block light and daylight numbers each have their own scale, so one can be enlarged without changing the other.
