SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill automates the end-to-end creation of Unity UI animations from a reference video and a JSON-based animation detector, reducing manual scripting and wiring tasks for UI flows.

Core Features & Use Cases

  • Data-driven animation generation: analyze a JSON detector to extract keyframes and object categories, then generate PrimeTween-based scripts.
  • Scene wiring and validation: wire scripts to scene GameObjects via MCP tools and verify behavior in Play Mode.
  • Reusable orchestration: support sequential and parallel animation patterns with UniTask, PrimeTween, and DI patterns for scalable features.

Quick Start

Read the animation detection JSON and reference video, generate PrimeTween-based C# scripts, wire them to the scene via MCP, and validate the result in Play Mode.

FAQPage Schema
How do I automate Unity UI animation from a JSON file?▼

You can automate Unity UI animation by analyzing a JSON detection file to extract keyframes and object categories, then generating PrimeTween-based C# scripts orchestrated with UniTask to drive the animations.

What's the best way to generate PrimeTween scripts from a reference video?▼

The best way is using a data-driven approach that reads an animation detection JSON alongside the reference video, extracting keyframes to automatically generate and wire PrimeTween C# scripts to scene GameObjects.

Does this Unity animation automation tool support UniTask orchestration?▼

Yes, UniTask orchestration is fully supported, enabling you to manage sequential and parallel animation patterns alongside PrimeTween and dependency injection patterns for scalable UI flows.

Can I wire generated animation scripts to scene GameObjects via MCP tooling?▼

Yes, generated PrimeTween scripts are wired directly to scene GameObjects using MCP tooling, and the results are automatically validated by running the scene in Unity Play Mode.

When does the animation generation process proactively run?▼

The generation process proactively runs when animation data is available in the JSON detection file but the corresponding PrimeTween-based C# scripts have not yet been generated.

How do I validate Unity UI animations created from JSON detection data?▼

You validate data-driven Unity UI animations by entering Play Mode after the MCP tooling wires the generated PrimeTween scripts to the scene GameObjects, allowing you to verify the behavior.
