Spec score 7.0 #17 of 22 in Minecraft Datapack Generators

What it is

RedScript is a programming language and toolchain for creating vanilla Minecraft datapacks, compiling code into .mcfunction files. Its datapacks run without mods, and a browser-based playground lets users write code and download a datapack. The language includes variables, functions, control flow, structs, enums, Option and Result types, f-strings, and modules. Minecraft-specific features include load and tick handlers, selectors, and command helpers. Its toolchain covers compilation, type checking, optimization, formatting, linting, testing, and watch mode. An LSP and VS Code extension provide diagnostics, completion, hover details, navigation, snippets, and syntax highlighting. RedScript also supports typed resource declarations and JSON or NBT contributions from files, with collision checks and directory or ZIP output. Static command checks can identify issues, but do not establish behavior on a live Paper server. Dimension and dimension_type resources require reopening the world. RedScript is free, open source, and released under the MIT License.

Strong points and limits

Strong points

  • Compiles typed code into .mcfunction files.
  • Browser playground can download datapacks.
  • VS Code extension includes diagnostics and completion.
  • Supports resource contributions from JSON and NBT files.

Limits

  • Static diagnostics do not prove live Paper behavior.
  • Dimension resources require reopening the world.

Who it suits

RedScript suits people building Minecraft datapacks, particularly larger projects that benefit from typed code and editor tooling. Its datapacks are designed to run without mods.

Verdict

RedScript combines a typed language with a broad toolchain for datapack development. Its static checks have a stated limit, and some resource changes require reopening the world.
