Vanilla Minecraft 1.19 Fireflies

Minecraft: *Cancels fireflies*
Me: No lol

This datapack will add the removed firefly mob in vanilla

With this datapacks, fireflies will spawn around your world in swamps, mangroves, jungles and lush caves!
The fireflies fly around and light up the area.
If you particularly like one firefly, you can catch it in a bottle and take it home! (and it'll never despawn)
Take on the challenge and catch the rare, blue firefly!
The fireflies emit a light level of 4
(They will destroy the "light_block"s with a lightlevel of 4, if this is somehow a problem, comment and I'll help you fix it)

Though I would never: Killing a firefly has a 50% of it dropping Glowstone Firefly Dust


Custom commands

/function fireflies:admin.summon
--- Summon a firefly
/function fireflies:admin.kill
--- Kill all fireflies



Technical

Spawning:
Every tick, a firefly will attempt to spawn at a random X and Z cordinate 0 to 100 away from the player at the player's eye height
If the chosen block is a vine, glow berry or dripleaf stem a firefly will spawn
A firefly which hasn't been put in a bottle and released again will despawn after 1 in-game day

Mobcap:
The fireflies have their own mobcap, every player can have 100 fireflies around them before they stop spawning

The real mob:
Fireflies are slowed down bats, being ridden by an armorstand, wearing a torch textured as the firefly
The bats are prevented from going to sleep
