Brinepool1

Based on game build 714014 | Last updated: 2026-02-28

Overview

brinepool1.lua is a static layout definition file used by the game's world generation system. It defines a fixed 14x14 tile grid layout for a specific Brinepool environment section, including background tile layers and foreground object groups. It specifies where features like saltstack areas (ground zones where saltstacks may generate) and cookiecutter spawners (points that trigger procedural object placement) are located. This file is not a component in the ECS sense but rather a data structure returned as a Lua table describing a static world region for use in map generation tasks and room placement.

Usage example

This file is loaded by the game's worldgen system during map assembly, not directly instantiated by modders. However, a typical usage within the engine would resemble:

local layout = require("map/static_layouts/brinepool1")
-- layout contains tile data and object definitions used by task/room systems
-- Example: a room placement system reads layout.layers[2].objects to locate spawners

Dependencies & tags

Components used: None — this is a data-only layout file with no runtime component logic. Tags: None identified.

Properties

The table returned by this file contains layout metadata defined at load time. The following are its top-level and nested fields:

Property	Type	Default Value	Description
version	string	"1.1"	Tiled map format version used.
luaversion	string	"5.1"	Lua version compatibility.
orientation	string	"orthogonal"	Map orientation type.
width	number	14	Width of the map in tiles.
height	number	14	Height of the map in tiles.
tilewidth	number	64	Width of a single tile in pixels.
tileheight	number	64	Height of a single tile in pixels.
properties	table	{}	Global map properties (empty here).
tilesets	table	—	Array of tileset definitions; includes ground tileset.
layers	table	—	Array of layers: BG_TILES (tile layer), FG_OBJECTS (object group).

layers structure

Layer property	Type	Description
type	string	Layer type ("tilelayer" or "objectgroup").
name	string	Human-readable layer name (e.g., "BG_TILES").
data	table (tilelayer only)	Row-major tile ID array (length = width * height). 0 means empty.
objects	table (objectgroup only)	List of objects with type, shape, x, y, width, height.

objects fields

Field	Type	Description
name	string	Object instance name (empty here).
type	string	Semantically meaningful category ("saltstack_area" or "cookiecutter_spawner").
shape	string	Geometry type ("rectangle").
x, y	number	Top-left position in pixels (relative to map origin).
width, height	number	Dimensions in pixels.
properties	table	Optional metadata (empty here).

Main functions

No functional methods are defined — this file exports only data. No runtime logic or functions are present.

Events & listeners

None — this file is data-only and has no event interaction.

Notes

• Tile IDs (e.g., 20 in data) refer to indices in the associated tileset (ground.tsx).
• saltstack_area rectangles define spawn regions for saltstacks; spawners likely activate procedurally placed objects within those bounds.
• cookiecutter_spawner objects (with zero size) denote spawn points for procedural objects — likely used by the cookiecutter system to instantiate features (e.g., small rocks or flora).
• Layouts like this are typically composed into larger maps via map/tasksets/, map/levels/, or map/rooms/ systems.
