Product first

Start with the package people need.

Each real upload keeps the manifest and spritesheet together. A generator can come later. The first job is simpler: make it easy to upload a pet, check the animation, and share the files.

Creator resources

Use the sample files if you want to check the format before uploading your own pet.

Generator notesCodex pet generator

Creator guideHow to create a Codex pet

Create a Codex pet by preparing pet.json, exporting an 8 by 9 spritesheet.webp, previewing animation rows, and publishing the package to a shareable gallery page.

Manifest referenceCodex pet.json format

Use this pet.json reference to name a Codex pet, describe it for the gallery, and point the package to the correct spritesheet.webp file.

Upload the two package files

pet.json needs id, displayName, description, and spritesheetPath.
spritesheet.webp should use 8 columns and 9 animation rows.
Keep the spritesheet file name exactly spritesheet.webp.

{
  "id": "happy-dog",
  "displayName": "Happy Dog",
  "description": "A cheerful pixel dog.",
  "spritesheetPath": "spritesheet.webp"

Codex Pet FAQ

What is a Codex pet?

A Codex pet is a small animated character for Codex. This site keeps its preview, manifest, and spritesheet on one page.

What should I upload?

The best upload is pet.json plus spritesheet.webp. Basic GIF, PNG, WebP, and SVG uploads still work for quick previews.

Is this a Codex pet generator?

Not yet. This version is a gallery and uploader. A generator makes more sense after the site has enough real packages to learn from.
