Project Flattened Utilities

by GacBL

Project Flattened Utilities gives server owners and command users a way to place custom structures from .nbt files, through commands that can be limited to chosen players.

What it does

Project Flattened Utilities is a lightweight Forge mod by GacBL for Minecraft 1.20.1. It lets a command spawn custom structures stored as .nbt files at the location where the executing player stands. The mod was built for the Project Flattened modpack, and it can also be used alone in other Forge-based 1.20.1 packs. The whole mod runs on client and server, so the server and every player need it.

Running the spawn command requires permission level 2 or higher. A whitelist file lists the players allowed to use it by UUID, and when that list is left empty, each player may call the command once unless a reset command clears their usage. The default structure is used when no name is given, and the player name argument is optional. The mod is open source under the MIT License and publishes its source code and issue tracker.

Key features

  1. Spawn structures from .nbt files

    Custom structures stored as .nbt files are placed at the player's current position through a command.

  2. Player whitelist by UUID

    A file lists the player UUIDs allowed to use the spawn command, while others are refused.

  3. One use per player

    Without a whitelist, each player may spawn a house once, and a reset command restores their ability to use it again.

  4. Default structure

    When no structure is specified, a default base is placed, so the command works with no arguments.

Use cases

Modpack starter bases

Pack authors can give each new player a prebuilt base at spawn without manual building.

Server events

Operators can place a prepared structure for a set of listed players, using the whitelist to limit access.

Who it’s for: The mod suits modpack authors and server owners on Forge 1.20.1 who want structures placed by command, and who can grant operator permission level 2 to the players that use it.

Questions

Does Project Flattened Utilities need to be installed on the server?

Yes. A server running it needs every connecting player to have it too.

Who can run the spawn command?

Players need operator permission level 2 or higher. The whitelist file can restrict use to specific player UUIDs.

Can a player spawn a structure more than once?

Without a whitelist, each player may call the command once unless a reset command clears their usage.
