Spawn Cap / Range Adjuster

Discord: https://discord.gg/BCHNhsDMXz

This mod allows you to adjust the maximum number of monsters allowed, as well as the maximum distance from player for a spawn to be valid.

Can be installed on server side only.

In a multi-player scenario where a lot of chunks are loaded, mobs will put a huge burden on server and it's not easy to optimize. Also, mob spawn will consume a significant portion of resources as well. This mod allows the following to be possible:

• Reduce the total number of mobs spawnable, and therefore reduce entity ticking lag of irrelevant monsters.
• Make sure mob spawn will not be run on chunks faraway from players
• Skip mob spawns in positions that are not relevant to player, making spawn calculation twice as fast

Since mob spawn is essential to a lot of technical minecraft contraptions, by default this mod does not change the vanilla spawn range. User can adjust the config to reduce spawn region and cap. The following operations are supported:

• Reduce spawn frequency. By default thid mod makes spawn check 4x less frequent.
• Limit maximum distance of mob spawn from nearest player (radius of spawn sphere)
• Limit maximum Y-diff of mob spawn from nearest player: Reduce underground spawn when player is on surface, reduce surface spawn when player is underground. This option will break most mob farms. Please inform player about it if you changed it. Mob farm designs can be changed to adapt this configuration.
• Reduce per-chunk monster cap (Vanilla cap is 70 monsters per 289 chunks. This number will increase with player count when players spread out and load a lot more chunks). By default it's limited to 30.
• Reduce total number of monster per dimension (there are no cap in vanilla). By default it's limited to 150.
• Reduce per-chunk / total number of each types of creatures, as a factor of vanilla cap per 289 chunks. By default per-chunk-cap is limited to 50% of vanilla, and max total is limited to 200% of vanilla single player creature cap.

FAQ:

• Q: Should I use this over InControl?
• A: InControl and this mod solve different issues. It's better to have both, while using this mod to reduce the maximum number of monsters spawnable, and use InControl to reduce spawn of specific monsters you find too frequent
• Q: What's the best setup, if mob farms are not of a concern:
• A: Set max spawn range to 64 blocks, max y-diff to 16 blocks, per-289-chunk cap to 30 monsters, and total cap to 150 monsters.
