GlymeraLightBlock - Craftable Light Sources

Light blocks you can craft, place and manage. The block vanishes on placement and leaves behind a permanent, invisible light source.

Most actual version only working for Hytale stable 5 ! Don't miss my other exciting projects — take a look at GlymeraCraft's Profile Discord: https://discord.gg/s5NRFWfxgy

What is GlymeraLightBlock?

GlymeraLightBlock lets players craft turquoise Light Crystals and place them anywhere in the world. When placed, the crystal block disappears and an invisible, permanent light source remains at that position. No visible objects, no clutter - just light where you need it.

Players manage their lights with simple commands. Server admins can set a per-player limit and manage lights for all players.

Pure server-side plugin - no client mod required.

How It Works

1. Craft a Light Crystal at the Workbench (1x White Crystal Block + 1x Crude Torch)
2. Place it anywhere in the world
3. The block vanishes instantly - a permanent light source stays
4. Remove lights with /glight remove or /glight clear

Behind the scenes, the visible block is replaced with an invisible light-emitting block (DrawType: Empty, Material: Empty). This block has no hitbox, no outline, and cannot be targeted or interacted with - it exists purely as a light source in the chunk data.

Features

• Craftable - No admin commands needed, players craft and place lights themselves
• Invisible light source - Block vanishes on placement, only light remains
• Permanent - Lights persist through server restarts and chunk reloads
• Per-player management - Each player manages their own lights
• Configurable limit - Admins set max lights per player (default: 100)
• OP tools - Admins can view, give and remove any player's lights
• No world clutter - No visible blocks, entities or particles at the light position
• Zero performance impact - Light blocks are just blocks, no ticking entities or AI

---

Performance

GlymeraLightBlock is extremely lightweight:

• Pure block-based - Light sources are invisible blocks in chunk data, not entities
• No tick overhead - Zero CPU cost per light (same as any other block in the world)
• Minimal memory - Ownership tracking only, lights themselves are stored as chunk data
• Lazy persistence - Ownership data is saved only when lights are added or removed
• Scales to thousands - A server can handle thousands of light blocks without any impact

---

Good to Know

• Light sources survive server restarts and chunk reloads natively (they are blocks, not entities)
• The light radius is 15 blocks (full brightness white light)
• Lights are only removable via /glight commands - they cannot be broken or interacted with
• Compatible with all other Glymera plugins including GlymeraLantern and GlymeraInspect
