Stalagmite Tall

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

Overview

stalagmite_tall.lua defines three variants (stalagmite_tall_full, stalagmite_tall_med, stalagmite_tall_low) of a tall stalagmite terrain structure. It provides mineable rock formations found in caves and the main world, releasing loot upon destruction. The prefab uses the workable component to handle mining progression and feedback, and the lootdropper component to spawn resources. It is part of DST’s world generation and environmental resource system.

Usage example

-- Typical internal usage (in prefab def)
local function fullrock()
    local inst = commonfn("full")
    inst.components.lootdropper:SetChanceLootTable('stalagmite_tall_full_rock')
    return inst
end

return Prefab("stalagmite_tall_full", fullrock, assets, prefabs)

Manual instantiation is not common; this prefab is typically spawned via worldgen or scenario logic.

Main functions

workcallback(inst, worker, workleft)

• Description: Handles mining progress. When workleft <= 0, triggers particle effect, drops loot, and removes the stalagmite. Otherwise, plays a dynamic animation based on remaining work (full, med, or low).
• Parameters:
  • inst (Entity) — the stalagmite instance.
  • worker (Entity) — the entity performing the mining (unused in this callback).
  • workleft (number) — remaining work units needed to finish mining.
• Returns: Nothing.
• Error states: None. Misuses or edge-case values are handled internally via math.random()–based animations and loot tables.

Events & listeners

• Listens to: None.
• Pushes: entity_droploot — fired when lootdropper:DropLoot completes.
