GlowingGlint — Dynamic Lighting Add-on

Glowing Glint (a.k.a. GG)

Is a behavior-only, lightweight dynamic lighting add-on with some extra features. No resource pack. Achievements enabled.

HOW IT WORKS?

Light is simulated by placing `minecraft:light_block` at the nearest available air block around an entity.

Just hold a light source item, and the script will do the rest.

Light blocks are only updated when you move or the light level change — idle entities cost zero overhead.

NEW IN V1.3.5

Spoiler

You can now add custom items to make them emit light via /gg:custom command (per player)

Add Custom Item:

Type the item ID manually. For example: minecraft:diamond_helmet

Add From Inventory:

Pick one item from your inventory. Items are sorted alphabetically (A–Z).

Once you select an item, you can configure the light level from 1 to 15. You can also override the light level of built-in items.

Selected items will be shown in the same /gg:custom menu.

Max is 5 custom items per player.

Flashlight (toggle) is now ON by default.

MAIN FEATURES

- Player Light: Detects items in both mainhand and offhand. If you hold two light sources, the highest level wins out.

- Burning Mobs: Any mob or player currently on fire caused by lava, fire, or enchantments (Flame & Fire Aspect) will illuminate their surroundings. 

- Glow Mobs: Native emissive support for Blaze (15), Glow Squid (9), Allay (6), Warden (5), and Magma Cubes (scaling 5–15 based on size).

- Item Drops: Dropped items emit light based on their type.

- Full Dimensional Support: Works across all 3 dimensions, including underwater.

⚠️ COMPATIBILITY

DO NOT combine this with other dynamic lighting add-ons since they will fight over the same block coordinates and cause TPS loss.

While optimized, a massive amount of emissive mobs in one area may impact performance. Though, you can toggle "Glow Mobs" off in the config menu if needed.
