The pack works on custom servers as well as in singleplayer. Because it's a data pack, it lives in the server's world and not on each player's computer.
Installing it on the server
1. Stop the server, or be ready to run a reload afterward.
2. Open the server's main world folder. It's the folder named after the world the server loads.
3. Open the datapacks folder inside it and place the pack file there.
4. Start the server. If it was already running, an operator can type /reload in chat or the console.
5. Run /datapack list to confirm the pack is enabled.
Your players should not need to install anything themselves. Data packs run on the server side, and connected players see the swamp fireflies when they visit at night.
Keeping the server healthy
- Performance: The pack uses a lightweight setup built to keep the world running smoothly, so it suits busy servers.
- Compatibility: Before adding it, check whether the server already runs packs or mods that change swamp biomes. Those are the only known conflicts.
- Player tips: Let players know the fireflies only appear in Swamp and Mangrove Swamp biomes after dark. Mention that a reduced Particles setting in Video Settings may hide them on their screen.
A shared swamp village or meeting spot makes a good showcase. The fireflies gather around trees, ponds and wooden builds at night.
