Shared hostile-mob behavior. Concrete mobs delegate to _monster hooks to avoid name collisions with base-trait methods.

fn is_dark_enough_to_spawn( level: &World, pos: BlockPos, random: &mut impl Random, ) -> bool

where Self: Sized,

Checks dimension light limits using the caller’s seeded RNG.

fn check_monster_spawn_rules( entity_type: EntityTypeRef, level: &World, spawn_reason: EntitySpawnReason, pos: BlockPos, random: &mut impl Random, ) -> bool

where Self: Sized,

Checks difficulty, light, and the spawn surface.

fn check_any_light_monster_spawn_rules( entity_type: EntityTypeRef, level: &World, spawn_reason: EntitySpawnReason, pos: BlockPos, ) -> bool

where Self: Sized,

Checks difficulty and the spawn surface without a light requirement.

fn check_surface_monsters_spawn_rules( entity_type: EntityTypeRef, level: &World, spawn_reason: EntitySpawnReason, pos: BlockPos, random: &mut impl Random, ) -> bool

where Self: Sized,

Adds sky visibility to monster spawn rules, except for spawners.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
