Walrus Camp

Based on game build 714014 | Last updated: 2026-03-07

Overview​

The walrus_camp prefab represents the walrus camp structure (an igloo-like building) that serves as a spawner and command center for walrus-based NPCs during winter. It manages the spawning and regeneration of walruses, little walruses, and icehounds using timers from the worldsettingstimer component. It tracks membership via homeseeker and follower components and reacts to world state changes (e.g., iswinter, startday) and events like megaflare_detonated to summon reinforcements. The camp is occupied only during winter and becomes empty when winter ends and all spawned members are gone.

Usage example​

-- The walrus_camp is typically spawned automatically via worldgen.
-- For modding, you can spawn it manually:
local camp = SpawnPrefab("walrus_camp")
camp.Transform:SetPosition(x, y, z)
-- Camp automatically starts tracking winter state and regenerating members.

Main functions​

SpawnHuntingParty(target, houndsonly)​

  • Description: Spawns a hunting party (walrus, little walrus, and up to two icehounds) if regeneration timers allow and the camp is occupied during winter. Sets up leader/follower relationships and assigns the combat target if provided.
  • Parameters:
    • target (entity or nil) — the combat target to assign to the walruses; if nil, no target is assigned.
    • houndsonly (boolean) — if true, only icehounds are spawned; if false, walruses and little walruses may also be spawned.
  • Returns: Nothing.
  • Error states: No explicit error handling; silent no-op if timers are active or world conditions not met.

CanSpawn(prefab)​

  • Description: Checks whether a member of the specified prefab type can be spawned — i.e., regeneration is enabled globally and no active timer exists for that prefab.
  • Parameters:
    • prefab (string) — the prefab name ("walrus", "little_walrus", or "icehound").
  • Returns: boolean — true if the member can spawn, false otherwise.

TrackMember(member)​

  • Description: Registers event callbacks and sets up homeseeker on a spawned member to bind it to the camp as its home. Ensures consistent tracking across spawns and despawn events.
  • Parameters:
    • member (entity) — the spawned walrus or icehound entity.
  • Returns: Nothing.

RemoveMember(member)​

  • Description: Stops tracking a member (removes event listeners and leader/follower bindings) and updates camp occupancy if necessary.
  • Parameters:
    • member (entity) — the member to stop tracking.
  • Returns: Nothing.

UpdateCampOccupied(inst)​

  • Description: Updates the camp’s occupancy state based on world season and presence of living children. If winter ends and no children remain, the camp becomes unoccupied.
  • Parameters: None.
  • Returns: Nothing.

SetOccupied(occupied)​

  • Description: Switches the camp’s visual and physical state. Occupied state uses the walrus_house build (collision active, foreground layer); unoccupied uses igloo_track (no collision, background layer). Also manages light state.
  • Parameters:
    • occupied (boolean) — true for occupied (winter), false for unoccupied.
  • Returns: Nothing.

Events & listeners​

  • Listens to:
    • death, onremove, newcombattarget, despawnedfromhaunt, detachchild (on members only)
    • onwenthome (on self) — removes the member who went home
    • megaflare_detonated (on TheWorld) — triggers delayed spawning near flare
  • Pushes: None.
  • World states watched: startday, iswinter — both trigger OnStartDay or OnIsWinter callbacks respectively.
