Fabric Per-Player-Spawns

This mod is intended to distribute mobs evenly between all players on a fabric modloaded server. To install, download the appropriate jar from the release section and place into your (server's) mod folder. The fabric-api mod is not required.

Copied and implemented as mixin from this Paper patch. With thanks to HalfOf2 from Fabric discord for the initial mixin work.

Forked from Lambdacraft because he went afk.

I rewired the mixins to work with 1.16.5, and then just rewrote that part of the mod as I see fit.

How it works: 

• modifies spawn logic to count chunks (and mobs in them) in a (square) radius around the player and account for chunks shared between the players
• radius to account is based on (server) render distance (like mob caps in vanilla)
• in the end each player has their own mob cap which applies to chunks around that player. (the most full one is applied in case of overlap)
• hold glistering melon in creative/spectator to see debug info

[This means if two players are relatively close to each other**, they can either have 70* mobs in the area between them, or 70* mobs each if no mobs are between them. Though, usually, it will be $70^*⋅1.5^{**}=105$ mobs, as intended by vanilla.]
* default monster mobcap, can be changed
** ~1 server render distance; $\frac{\text{N chunks loaded by these playres}}{(SRD⋅2+1)^2}$

Works with Proper Mobcap Modifier (by me)
