Bluemush

Based on game build 714014 | Last updated: 2026-02-27

Overview

This script defines room templates for the blue mushroom cave biome in Don't Starve Together's world generation system. It specifies multiple room variants (e.g., "BlueMushForest", "BlueSpiderForest", "MoonMushForest") that contain distinct distributions of prefabs such as mushtree_tall, blue_mushroom, dropperweb, and batcave. Each room is registered via AddRoom() with associated visual and functional properties including tile type, colour tint, tags, and probabilistic content generation rules. This file contributes to the procedural mapping of cave levels, particularly the blue fungal caverns.

Usage example

This file does not define a component usable by modders at runtime. It is used internally during world generation to populate cave levels with themed rooms. Modders should register custom room definitions using AddRoom() and Roomify() from map/room_functions.

-- Example custom room registration (not part of this file)
require "map/room_functions"

AddRoom("MyCustomBlueMush", {
    colour = {r=0.1, g=0.1, b=0.8, a=0.9},
    value = WORLD_TILES.FUNGUS,
    tags = {"Hutch_Fishbowl"},
    contents = {
        distributepercent = 0.5,
        distributeprefabs = {
            mushtree_tall = 4.0,
            blue_mushroom = 1.0,
        },
    },
})

Dependencies & tags

Components used: None — this script operates at the world generation layer and does not interact with in-game entity components.

Tags: All blue mushroom rooms are tagged with "Hutch_Fishbowl" (except "MoonMushForest" and "MoonMushForest_entrance", which have no tags or "GrottoWarEntrance" respectively). Tags influence room selection and placement logic.

Properties

This script does not define an ECS component or data structure with persistent instance properties. Instead, it registers static room definitions via AddRoom().

None applicable.

Main functions

This script does not define a component with public methods. It contains only top-level function calls: AddRoom() and Roomify().

• AddRoom(name, roomdef) — Registers a named room definition for world generation. The roomdef table includes colour, value, tags, and contents.
• Roomify(roomdef) — Wraps a room definition (like bgbluemush) into a format suitable for direct room placement in static layouts.

Events & listeners

None — this script does not use events or listeners, as it executes during map generation before gameplay begins.
