About this Mod

Project Flattened Utilities

Project Flattened Utilities is a lightweight custom mod developed for the Project Flattened modpack. It enables players to spawn custom structures from .nbt files.

✨ Features

`/spawnHouse <fileName>`

Spawns a structure at the player's current location.
<fileName> is optional; defaults to default_base if not specified.
All .nbt files should be placed in:

  /config/pf_schematics

This command can only be run once per player (unless reset with /clearHouse).

`/clearHouse [playerName]`

Resets a player’s ability to use /spawnHouse.
Requires permission level 2 or higher.
[playerName] is optional. If not provided, it applies to the executing player.

⚙️ Configuration

A config file is created at:

/config/projectflattenedutilities-common.toml

This file allows you to whitelist specific players (via their UUIDs) who are allowed to use the /spawnHouse command.

If left empty, it will allow every player to call it at least once, unless /clearHouse was used on them.

📦 Use in Other Modpacks

While built specifically for Project Flattened, this mod is standalone and can be used in any Forge-based 1.20.1 modpack.

Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Project Flattened Utilities consumes the most tick time.
