Frequently asked questions

How do I add the fireflies data pack to my world?
Put the pack in your world's datapacks folder, or select it on the data pack screen when creating a new world. Then load the world, or run /reload if it is already open. Run /datapack list to confirm it appears among the enabled packs.
Which biomes do the fireflies show up in?
The pack spawns ambient firefly particles in the Swamp and Mangrove Swamp biomes. Other biomes stay as they are in vanilla.
I installed the pack but I don't see any fireflies, what am I doing wrong?
The fireflies are a nighttime effect, so wait for night or set the time to night. Make sure you are actually standing in a Swamp or Mangrove Swamp. Look around the trees and ponds, where the lights float.
Do the fireflies show up during the day?
The pack is designed for night. The tiny lights float around trees and ponds after dark, so visit swamps at night to see them.
