DistributedMobSpawns

This plugin will no longer be updated due to https://github.com/PaperMC/Paper/pull/2171 being merged. However the plugin is still useful for older server versions without the patch.

To use Paper's new mob spawn distribution, use the latest 1.14.4 or higher build and set per-player-mob-spawns to true.


Background information

Multiplayer natural mob spawning has a fatal flaw. It uses a global cap that is essentially only dependent on the number of chunks loaded. This means areas with lots of dark areas will get more mob spawns over other areas. This can lead to the situation where some players have many more mobs around them over other players.




Features

DistributedMobSpawns aims to solve this issue by preventing mob spawns around players who have exceeded the spawn limit around their mob-spawn-radius area.

• Avoid situations where too many monsters spawn in player made dark room monster farms.
• Also avoid situations where no monsters spawn in monster grinder when more than 1 player is online.
• Avoid lag by preventing too many fish spawns.

Note: Since most animals are spawned using chunk generation and not through natural spawning, the animal limit has some issues.

Install
A Paper server is recommended so that only naturally-spawned mobs count towards the limit.
Just drop into plugins folder and restart.
config.yml available to tweak responsiveness/lag settings.
It is recommended that the mob-spawn-range is 8 in spigot.yml and view-distance is 10.
