What is it?

What it is

An open-source, no-UI 2D animation and game asset generation platform that allows users to create scenes, spritesheets, and animations through text prompts and Codex integration, enabling rapid prototyping without manual workflows.

Why it exists

To simplify game creation by automating asset generation and scene composition via Codex, reducing reliance on traditional animation tools and manual pipelines for 2D game development.

Who should use it

Developers and creators comfortable with Node.js and command-line tools who want to use AI-assisted workflows (via Codex) for generating 2D game assets, scenes, and animations without manual animation work.

Who should avoid it

Users who prefer traditional GUI-based animation tools, are unfamiliar with Node.js/npm, or seek a zero-setup, no-code experience without any technical configuration.

FAQ

How does the Codex-assisted workflow work for generating animations?

You can describe your desired animation or scene in prompts, upload reference images, and Codex will call the local agent to generate or modify spritesheets. The app then previews the animation directly in the browser for immediate feedback.

What are the best practices for creating consistent spritesheets?

Generate full spritesheets first, maintain uniform frame sizes, keep characters/props centered, preserve proportions, and ensure stable base anchors to avoid inconsistencies during playback.

How can I save and reuse scenes or assets?

Scenes and assets are saved locally in `public/generated/`. You can reuse spritesheets, backgrounds, or scenes by inserting them into new scenes via the `Spritesheets` page or `2D Canvas`.

How do I edit metadata for spritesheets?

Metadata like loop mode, trigger type, and game state can be edited directly in the `Spritesheets` page. This allows reusable assets to adapt to different scene logic or gameplay requirements.

Can this tool handle non-character animations?

Yes, it supports animating props, UI elements, and background elements. You can create separate clips for props, UI interactions, or environmental effects alongside character animations.

How can I modify the tool's framework itself?

You can use Codex to describe changes to the tool's structure, workflows, or codebase. The app is designed to evolve with user feedback, allowing direct modifications to its framework through prompts.
