From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Aikar Date: Sun, 24 Mar 2019 01:01:32 -0400 Subject: [PATCH] Only count Natural Spawned mobs towards natural spawn mob limit This resolves the super common complaint about mobs not spawning. This was ultimately a flaw in the vanilla count algorithim that allows spawners and other misc mobs to count against the mob limit, which are not bounded, and can prevent the entire world from spawning new. I believe Bukkits changes around persistence may of actually made it worse than vanilla. This should fully solve all of the issues around it so that only natural influences natural spawns. diff --git a/src/main/java/net/minecraft/world/level/NaturalSpawner.java b/src/main/java/net/minecraft/world/level/NaturalSpawner.java index 029835914c3c88811684e90b29bfed83191b3b3f..05c014c5f0805d50cfd251b043c79ce3355eef16 100644 --- a/src/main/java/net/minecraft/world/level/NaturalSpawner.java +++ b/src/main/java/net/minecraft/world/level/NaturalSpawner.java @@ -88,6 +88,13 @@ public final class NaturalSpawner { MobCategory enumcreaturetype = entity.getType().getCategory(); if (enumcreaturetype != MobCategory.MISC) { + // Paper start - Only count natural spawns + if (!entity.level.paperConfig().entities.spawning.countAllMobsForSpawning && + !(entity.spawnReason == org.bukkit.event.entity.CreatureSpawnEvent.SpawnReason.NATURAL || + entity.spawnReason == org.bukkit.event.entity.CreatureSpawnEvent.SpawnReason.CHUNK_GEN)) { + continue; + } + // Paper end BlockPos blockposition = entity.blockPosition(); chunkSource.query(ChunkPos.asLong(blockposition), (chunk) -> {
