game-dev

Provide a natural-language brief describing the game, and the pipeline generates a visual target image, decomposes risks, plans architecture, generates art assets, implements gameplay in Babylon.js, and verifies it with screenshots before deployment.

It uses Babylon.js for rendering, scene graph, physics, and input, hosted inside a React WebDev project. Gameplay code lives in framework-agnostic TypeScript classes under client/src/game, mounted through a full-screen GameCanvas component.

Yes. The skill replaces godogen's paid Gemini, Grok, and Tripo3D CLIs with Manus built-in image generation for reference images, textures, sprites, and backgrounds. Generated PNGs are uploaded and used directly as Babylon textures.

By default it uses procedural meshes textured with generated images, since there is no built-in image-to-3D generation. GLB models are only used if the user supplies a Tripo3D key, following godogen's asset generation path.

The game is deployed exclusively through WebDev Publish to a manus.space domain after a checkpoint is saved. Temporary expose or proxy links are explicitly forbidden as the final deliverable.

React 19 StrictMode mounts effects twice in development, which can initialize two Babylon engines on one canvas. Guard engine initialization with a ref flag and dispose the engine on unmount, as shown in the GameCanvas template.
