✨ NoteBlock Glow — True Light Edition

Note blocks that actually emit light when powered by redstone. Not just a texture trick — real light level 15 that illuminates surroundings and prevents mob spawning.

What's included

This download contains two components that work together:

Component Type Purpose download
NoteBlockGlow_ResourcePack Resource Pack Brighter texture when powered download
NoteBlockGlow_DataPack Data Pack Places invisible light blocks on activation

How it works

  1. Mark note blocks you want to glow: stand on them and run /function nb_glow:mark_here
  2. Power the note block with redstone
  3. Light appears — an invisible light[level=15] block spawns above the note block
  4. Power off — light block auto-removes

Installation

Resource Pack:

  1. Drop into .minecraft/resourcepacks/
  2. Enable in-game

Data Pack:

  1. Unzip to .minecraft/saves/<YourWorld>/datapacks/NoteBlockGlow_DataPack/
  2. Run /reload or rejoin the world
  3. Stand on any note block and run /function nb_glow:mark_here

Commands

Command Function
/function nb_glow:mark_here Mark the note block under your feet
/function nb_glow:uninstall Remove all lights and markers

Features

  • Real light emission — affects mob spawning, crop growth, screenshot exposure
  • Per-block control — only marked note blocks glow; unmarked ones stay normal
  • Automatic — once marked, no further commands needed; redstone handles on/off
  • Clean removal — uninstall command restores everything

Limitations

  • Manual marking required — each note block must be marked individually; cannot auto-detect existing note blocks
  • Space above needed — the block directly above the note block must be air for light to place
  • Chunk-loaded only — marked blocks outside loaded chunks won't respond until you return
  • Single-player or server-op only — data pack requires command permissions

Technical

  • Uses minecraft:marker entities to track marked positions
  • Detects powered blockstate via execute if block
  • Places/removes minecraft:light[level=15] blocks dynamically
