Retrofit Fumarole

Based on game build 714014 | Last updated: 2026-03-02

Overview

This file is a static layout definition for a fumarole-themed area in the Caves. It is not an ECS component, but a standalone Lua table conforming to the Tiled JSON-exported format (v1.1), used by the world generation system to place visual and functional objects. It contains:

• A single tile layer (BG_TILES) for background floor tiles (tile ID 52 used consistently).
• An object group (FG_OBJECTS) listing prefabs to instantiate, including:
  • cave_vent_rock — decorative vent rocks.
  • tree_rock — large rock formations.
  • cave_fern_withered, flower_cave_withered, flower_cave_double_withered, flower_cave_triple_withered — withered flora.
  • cave_vent_mite_spawner, shadowthrall_centipede_spawner — entity spawners for fauna.
  • retrofit_fumaroleteleporter — a teleporter anchor.

It serves as a blueprint consumed during worldgen to populate the fumarole biomes in the Caves.

Usage example

This file is loaded by the engine during world generation and not directly instantiated by modders.

-- Internally used like this (simplified pseudocode):
local layout = require("map/static_layouts/retrofit_fumarole")
-- layout.version, layout.width, layout.height, layout.layers[]
-- The game's map builder parses 'layers' and spawns prefabs from 'FG_OBJECTS'.
