Project settings

Set the basics for your pack. The namespace is the id used in every generated file path, e.g. data/<namespace>/origins/...

Basics

Namespace (lowercase, no spaces)

Used as the mod/pack id in every file path and every generated identifier.

Pack display name

Author (optional)

Target Minecraft version

Controls the pack_format written to pack.mcmeta.

Origins

An origin is a playable identity — Human, Elytrian, Blazeborn, etc. Give it an icon, a rarity/impact, and a set of powers.

New origin

Name

Description

Icon (item id)

Impact (0 = none, 3 = major)

Order (sort position)

Unchoosable (hidden from the selection screen — e.g. reserved for commands/other mods)

Powers from this project

Extra power ids (comma separated — for powers from other datapacks, e.g. origins:speed)

Id	Name	Impact	Powers

Powers

A power is one ability — an attribute boost, an action trigger, a resource bar, and so on. Pick a preset to prefill common fields, then adjust anything you need.

New power

Quick preset

Name

Description

Power type

Icon (optional — only used by a few power types, e.g. resource bars)

Hidden (don't show in the origin's power list on the selection screen)

Extra fields (type-specific data)

Edit as raw JSON instead (advanced / any power type not covered above)

Preset fields are a starting point, not guaranteed schema — Origins power fields differ across mod versions. Check the Origins docs if something won't load in-game.

Origin layers

A layer is a choice slot on the origin screen (the default one is called origin). Without a layer including your origins, they won't be selectable in-game.

Order

Enabled Replace (overrides a layer of the same id from another pack)

Origins included (leave all unchecked to auto-include every origin)

Export

Datapack (.zip)

Works immediately — drop the zip into a world's datapacks folder (Origins mod must already be installed on that server/client). No Java, no build tools.

Fabric mod project (.zip)

This produces a buildable Gradle project, not a compiled .jar. A browser tool can't run a Java compiler, so this can't hand you a finished mod jar directly. What you get is a Fabric mod skeleton with your origins/powers/layers already placed in src/main/resources/data/..., plus a fabric.mod.json and a build.gradle template. Open it in an IDE, fill in the Fabric Loom/Yarn versions for your target Minecraft version (from the Fabric wiki), and run ./gradlew build to get the jar.

Import

Load an existing datapack .zip, a Fabric mod project .zip, or a mod .jar that bundles a datapack (jars are just zip files, so this tool reads them the same way). It scans for data/<namespace>/origins, /powers, and /origin_layers JSON and loads it into the editor.
