Struct SpawnLimits 

pub struct SpawnLimits {
    pub monster: u32,
    pub creature: u32,
    pub ambient: u32,
    pub axolotls: u32,
    pub underground_water_creature: u32,
    pub water_creature: u32,
    pub water_ambient: u32,
}

How many mobs of each spawning category a level’s natural spawning allows (MobCategory.getMaxInstancesPerChunk), read and set through LevelRef::spawn_limits and set_spawn_limits. Each limit counts twice, as vanilla’s own does: the level spawns a category only while its count of that category’s mobs stays under limit * spawnable chunks / 289 (one player’s 17 by 17 chunks hold the vanilla value), and only in a chunk with a player near it who has fewer than limit of them around. A limit of 0 stops the category’s natural spawning. MobCategory::Misc never spawns naturally, so it has no limit.
