1 release, newest first.
SnPacketBosses gives a player a boss fight that only they can see, and makes them mine it down with EdTools instead of hitting it.
The boss is not an entity. It exists only as packets sent to its owner, so it does not count against the entity cap, does not tick, does not path, cannot be hit or looted by anyone walking past, and cannot be griefed off a claim. Two players standing next to each other can be fighting two different bosses and neither one sees the other's.
A boss is summoned from a boss egg: an ordinary item players can buy, sell, store and trade. Each egg carries its own attempt count in its item data, so an egg is worth exactly what it says it is worth, and a renamed one still works while a hand-crafted lookalike does not.
Damage comes from EdTools block breaks. Every block the owner mines takes health off the boss, so the fight is paced by their gear and their mine rather than by their reach. A boss bar tracks health and the clock, and a private hologram floats over the boss with whatever text the file defines.
Run the clock out and the egg comes back reading one attempt fewer. At zero it is gone.
Each boss can carry three, in any combination, all telegraphed before they land:
A boss either orbits its owner and follows them across worlds, or sits pinned at a fixed location. A following boss keeps up smoothly through sprint, elytra and Speed effects, and snaps cleanly rather than sliding when it falls too far behind.
Quit mid-fight and the fight pauses; it is restored when you come back, health, clock and attempts intact. Teleport, change world, die or reload the server and the boss is redrawn where it belongs. When a fight ends, it ends the same way every time, whether it was won, timed out, killed by an admin, or interrupted by a server restart.
Every boss is one file in bosses/, and the file name is the boss id, so adding a boss means
adding a file. The folder is seeded once on a fresh install and never written to again: a file
you delete stays deleted.
While a fight is running you can restrict commands, teleports and flight, with an allowlist
and a bypass permission. /packetbosses always stays available so an admin can never be
locked out of ending a stuck fight.
Commands are /packetbosses give, kill, list and view, plus the reload, help and
debug SnLib injects. view lets an admin watch someone else's fight over their shoulder;
the spectator sees everything and can change nothing.
Every player-facing string lives in the language file. There is no hardcoded text.
SnDevelopmentSnLib.jar goes in plugins/. SnPacketBosses does not run without it.plugins/ and start the server. It writes its own config.yml, its
language file and an example boss on first boot.
