NoteBlock Glow DataPack

✨ 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
