    Why no grade

    About

    Harry’s Lib is a script library for other MTR and NTE resource packs, providing train-motion calculations such as updating and storing wheel angles based on speed and direction, tracking braking and acceleration, and detecting turns from changes in car rotation. It also loads train models in separate parts with per-model rendering settings and optional UV mirroring, and calculates car rolling and rocking from speed, turning angle, and mass. The library supplies scripts for models added by other resource packs rather than adding those models itself; for example, a bus model from another pack uses its scripts to work correctly.

    Written from Modrinth . How we write it

    Security

    No harmful code found

    We checked what is inside its files, without opening them in the game.

    Why we show this: a resource pack cannot run programs, but its file can hide one. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade.

    How we checked · Both 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.
      2 latest files: the newest file for each Minecraft version and loader. The answer above is about the one for a recent version. 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
    • 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.

    Privacy

    Sends nothing

    A resource pack has no code that can connect to the internet, so it cannot send anything about you.

    AI

    No sign that AI was used to make it

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

    Why we show this: some players and servers avoid projects made with AI. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
