RedScript
What it is
RedScript is a typed programming language and toolchain for creating Minecraft datapacks that compile to .mcfunction files and run without mods. Builders can try it in an online playground, write code in a browser, and download a datapack. The language includes variables, functions, control flow, structs, enums, Option and Result, f-strings, and modules. Minecraft-specific tools cover load and tick handlers, selectors, and helpers for commands such as title, kill, and particle. Its toolchain includes compilation, type checking, optimization, formatting, linting, testing, and watch mode. An LSP and VS Code extension offer diagnostics, completion, hover details, navigation, snippets, and syntax highlighting. The standard library includes math, vectors, random generators, particles, inventory, scheduling, and ECS-style helpers. RedScript also supports typed resource declarations and JSON/NBT contributions from files, with collision checks and directory or ZIP output. Static command checks do not establish behavior on a live Paper server. Dimension and dimension_type resources require reopening the world; normal resources and structure NBT are described as reloadable. It is free, open source under the MIT License.
For and against
For
- Compiles typed code to vanilla datapacks without mods
- Online playground supports browser coding and downloads
- VS Code extension includes diagnostics and autocomplete
- Supports resource declarations and JSON/NBT contributions
Against
- Static diagnostics do not prove live Paper behavior
- Dimension resources require reopening the world
The verdict
RedScript combines a typed language with a broad toolchain for Minecraft datapack authoring. Its static checks and resource workflow have stated limits, so builders should account for those when validating a project.
Who it suits
RedScript suits people building Minecraft datapacks, particularly those working on larger projects. Its browser playground can help users try code without starting with a local setup.
