Struct FinalizeSpawnEvent 

pub struct FinalizeSpawnEvent<'a> {
    pub dimension: &'a str,
    pub kind: &'a str,
    pub reason: SpawnReason,
    pub pos: [f64; 3],
    pub spawner: Option<SpawnSource>,

What Hooks::finalize_spawn is told. Each field is that hook’s argument of the same name, described in the hook’s doc.

Fields

dimension: &'a str

kind: &'a str

reason: SpawnReason

pos: [f64; 3]

spawner: Option<SpawnSource>

difficulty: &'a mut Difficulty

spawn_cancelled: bool

mob: UnspawnedMobRef

edits: &'a dyn UnspawnedMobEdits

group: &'a mut Option<SpawnGroup>

cancelled: bool

Whether the event is cancelled: by the game or an earlier listener, or by this one setting it. Only a listener that receives cancelled events (#[listener(receive_cancelled)]) sees true, and setting it back to false lets the game’s behaviour run.
