Struct SpawnFlags 

pub struct SpawnFlags {
    pub monsters: bool,
    pub friendlies: bool,
}

Which categories a level’s natural spawning (NaturalSpawner.spawnForChunk) may spawn at all, read and set through LevelRef::spawn_flags and set_spawn_flags. A flag only takes away, for its level alone: monsters still need the spawn_monsters game rule, and nothing spawns naturally with spawn_mobs off. Spawners, patrols, sieges, phantoms, a new chunk’s creatures and other custom spawners don’t read the flags.

Fields

monsters: bool

Whether MobCategory::Monster spawns: off acts as the spawn_monsters rule off does (getFilteredSpawningCategories’ spawnEnemies).

friendlies: bool

Whether every other spawning category spawns: creatures, ambient and water mobs, axolotls. Horizon’s own; vanilla has no such switch.
