Cave Fern

Based on game build 714014 | Last updated: 2026-03-04

Overview​

cave_fern is a non-player entity prefab representing decorative and harvestable foliage found in caves. It uses the pickable component to allow players to harvest it for foliage, and integrates with DST’s burn and ignite systems for environmental interactivity. As a prefabricated asset, it is defined via a factory function fn() that constructs the entity, sets up animations, components, and save/load hooks, and returns a fully configured Prefab.

Usage example​

-- Typical usage within a level generator or worldgen task
local inst = SpawnPrefab("cave_fern")
inst.Transform:SetPosition(x, y, z)
inst:AddTag("plant")

Dependencies & tags​

Components used: pickable, inspectable Tags: None explicitly added or removed. The MakeSmallBurnable, MakeSmallPropagator, and MakeHauntableIgnite helper functions modify internal behavior but do not add new tags.

Properties​

No public properties are defined in the constructor. The animname is assigned but is internal state.

Main functions​

Not applicable. This is a prefab factory, not a component. No component-level methods are defined.

Events & listeners​

  • Listens to: None directly.
  • Pushes: None directly.
  • Save/Load hooks:
    • onsave(inst, data) — serializes inst.animname into the data.anim field.
    • onload(inst, data) — restores animname and replays the animation if present in loaded data.

Note: The pickable component contributes its own events (onpick, onregen, etc.) and listeners internally, but cave_fern does not register additional event handlers beyond save/load hooks.
