Guides

Start from what you are here to do.

Play

• Joining a server: add a server in Minecraft, which versions connect, and what to try when you cannot.
• Commands and functions: how commands work, and running .mcfunction files from a datapack.

Host a server

• Running JSPrismarine: download the prebuilt server, start it, and update it.
• Every setting: what each key in config.json does.
• Worlds and world seeds: presets, dimensions and seeds.
• Log levels: what each level prints and how to choose one.

Build add-ons and plugins

• Extending JSPrismarine: packs for content, and embedding the server for code.
• Using packs: which pack formats load and how a stack composes.
• Run from source: pnpm run dev, which restarts the server when your pack or code changes.

Work on JSPrismarine

• Contributing: how to set up, test and send a change.
• Package versioning: which Changeset level a change needs.
• The data-driven engine: how vanilla behavior comes from data.
