    About

    Moog's Structure Lib is a library for mod and datapack creators who want to build custom structures and control how they generate in Minecraft worlds. It extends vanilla jigsaw generation with separate structure types for the Overworld and Nether, and adds placement controls such as exclusion zones, minimum distance from spawn, and frequency reduction. Structures can be single pieces or expand through connected template pools into larger layouts, with terrain-aware placement options to seat builds on uneven ground or search Nether terrain for a suitable location. Its structure processors add behavior that vanilla generation does not provide, including randomizing spawner mobs, setting vault loot, flooding builds, sealing them against nearby lava or water, and extending pillars to meet terrain. Other processors can remove unsupported floating blocks, settle pieces onto terrain, weather blocks while preserving their properties, and equip armor stands with randomly selected armor. The library includes a barn example and documentation that walks creators through simple structures as well as complex jigsaw builds such as a cathedral. It can be installed server-side only and supports Forge, Fabric, and NeoForge.

    Written from Modrinth . How we write it

    In-game changes

    Changes the game's code in 5 areas, as a library other mods build on: World generationChanges 7 game code files in this area: terrain, biomes and structures made when new land is created., Game data and resourcesChanges 1 game code file in this area: recipes, tags, advancements, language files and other game data., Game coreChanges 1 game code file in this area: the main loop, lighting and other code the whole game uses., Server and world logicChanges 1 game code file in this area: the world, commands, scoreboards, saved data and game rules. and Chunk loading and storageChanges 1 game code file in this area: how the game loads, tracks, saves and unloads chunks..

    Adds no new blocks, items or other content.

    Keeps all of vanilla Minecraft's textures, models and sounds.

    Security

    No harmful code found

    We checked its files and read their code, without running it.

    What it can do on your computer

    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. Only in its files for Fabric 1.20 to 1.21.8, 1.21.10 to 26.3; NeoForge 1.21 to 1.21.8, 1.21.10 to 26.3; Forge 1.20 to 1.21.8, 1.21.10 to 26.3. See Privacy
    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them. Only in its files for Fabric 1.20 to 1.21.8, 1.21.10 to 26.3; NeoForge 1.21 to 1.21.8, 1.21.10 to 26.3; Forge 1.20 to 1.21.8, 1.21.10 to 26.3.

    Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.

    How we checked · All 36 latest files checked, last on 16 Oct 2026
    • FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.
      36 latest files: the newest file for each Minecraft version and loader. The answer above is about the 30 for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
    • Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.
      Read without running it
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.
      Nothing declared about your system outside the game.
    • Looked for, not foundWe looked for these in the file and did not find them.
      Folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.

    Privacy

    We found nothing it sends

    We read its code without running it: it contacts no web address while you play.

    Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.

    How we checked · All 30 files read
    • Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.
      The code of all 30 files, for recent Minecraft versions. See each file in Releases
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.
      Nothing declared about crash reports, usage data or advertisements.

    AI

    AI was used to make it

    The author writes that AI was used.

    We looked for AI tools in its texts, files, images and code history and found none.

    No sign of AI in the game

    We found no AI service, AI library or AI model file in its code.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
