Content Workbench — Item & Recipe Editor

Your item data, ready for the next step. Create item catalogs and crafting recipes in Unity, bring in JSON or CSV, and review changes before applying them. Content Workbench helps you catch missing references and keep shared project rules consistent.

Version 1.1 · Full C# source · Offline documentation · Playable integration example

From content to gameplay

01 · Author Items, recipes and stable IDs.

02 · Review Additions, edits and removals.

03 · Validate References and project rules.

04 · Integrate Runtime lookup and atomic crafting.

A practical starting point

The included Caravan Workshop is a small, playable outpost. Buy materials, bake bread, brew a tonic, pack supplies and deliver a field pack for coins. The item names, icons, costs and outputs all come from the same catalog.

12 items · 9 recipes · 12 included sample icons

Inspect items, filter the inventory, craft multiple batches and save or load a run. Game commands, inventory storage, UI Toolkit presentation and file persistence have separate integration boundaries, with a guide explaining how to replace each layer.

Built for a reviewed workflow

• Authoring: search, categories, stable IDs, duplication and recipe reference navigation.
• Import & review: strict JSON and three-table CSV, explicit Merge/Replace and field-level differences.
• Shared validation: workspace profiles, category/value rules and optional or required Sprite bindings.
• Recovery: local drafts, Undo/Redo and pre-apply checkpoint history.
• Runtime: indexed catalog queries, validated snapshot reloads and an atomic crafting reference adapter.
• Automation: Unity batch validation/review/apply and optional .NET CLI source.

What you receive

One ZIP with alternative UPM and .unitypackage installation formats, editable source, JSON schemas, offline setup/API guides, license and dependency notices. Includes Caravan Workshop, the minimal Runtime Crafting Demo and Starter Catalog Data. Install only one package format in a project.

Caravan Workshop includes editable UXML/USS, a configured scene, catalog, profile, workspace and selected Copper Caravan icons. No separate illustration purchase is required.

Requirements

Verified with Unity 6000.6.5f1 on Windows x64 and a Windows x64 Mono player. Requires Unity's com.unity.nuget.newtonsoft-json 3.2.2. UPM resolves it; install it first for the .unitypackage format. The optional CLI source requires .NET 8.

No activation account, AI provider or subscription is required to use the tool.

Integration scope

The sample inventory tracks quantities, capped at 99 per item type. Its grid is a presentation of item types, not a slot inventory. The project does not include equipment, multiplayer authority, quest progression, save migrations, Addressables, Sheets sync or MCP transport. Adapt the documented inventory and persistence contracts for your own game. Other engine versions, platforms, backends and render pipelines have not been verified for the new scene.
