Lavae Tooth

Based on game build 714014 | Last updated: 2026-03-05

Overview​

lavae_tooth is a prefab that functions as a visual and logical placeholder for the Lavae boss's pet-spawning mechanism. It exists as a small, floating inventory item (an "egg tooth") and enables controlled spawning of the lavae_pet via the petleash component. When removed (e.g., via despawn or ownership loss), it triggers a cleanup sequence that spawns small_puff FX, converts itself to ash, and attempts to return the ash to its original inventory/container slot if available. This prefab is integral to the Lavae boss fight progression.

Usage example​

-- Typically created internally via the prefab system
local tooth = SpawnPrefab("lavae_tooth")

-- When attached to a Lavae entity (e.g., as a boss token), the petleash component manages pet lifecycle
if tooth.components.petleash then
    tooth.components.petleash:SpawnPet()  -- triggers OnSpawnFn (see below)
end

Main functions​

OnSpawn(inst, pet)​

  • Description: Executed when the lavae_pet is spawned. Plays a spawn FX (small_puff) unless nospawnfx is set, and registers a listener for the pet's onremove event to trigger cleanup.
  • Parameters:
    inst (Entity) — the lavae_tooth instance.
    pet (Entity) — the spawned lavae_pet.
  • Returns: Nothing.

OnDespawn(inst, pet)​

  • Description: Executed when the lavae_pet is removed manually or via despawn. Spawns small_puff FX, clears the onremove listener, and destroys the pet entity.
  • Parameters:
    inst (Entity) — the lavae_tooth instance.
    pet (Entity) — the despawned lavae_pet.
  • Returns: Nothing.

OnPetLost(inst, pet)​

  • Description: Called when the lavae_pet is removed. Spawns ash, attempts to retain inventory slot position if the original owner had an inventory or container, and emits a sound. This ensures ash remains contextually placed (e.g., in player inventory).
  • Parameters:
    inst (Entity) — the lavae_tooth instance.
    pet (Entity) — the lost lavae_pet.
  • Returns: Nothing.

Events & listeners​

  • Listens to: onremove (on the lavae_pet instance) — triggers OnPetLost when the pet is removed.
  • Pushes: None identified.
