Created by	LX86

A Light Source Block is a block that does not have a visual appearance nor a collision hitbox, and can emit lights from 0 - 15.

When the player is holding the Light Source Block Item, all Light Blocks around the player will display a Light Icon.

This behavior is the same as the light block introduced in Minecraft 1.17, except survival player can still see the hitbox without holding the item.

Usage

• Right Click the Light Block when holding the Light Block will cycle the light level from 0 - 15
• The blocks placed with the item will always have a light level of 15

Trivia

• This block is originally just called Light Block, however during a language cleanup this is renamed to Light Source Block
• The icon displayed when holding this block is originally going to be rendered by a Block Entity Renderer rather than Minecraft's Particle System. However due to concerns over performance and failing to render the icon properly, this has been changed to a particle system. (The block entity itself however remains until v1.1.4)
