Spritesheets

The default layout

The builder's defaults expect a sheet 8 columns wide with cells of 192 × 208 pixels, one move per row:

row 0  idle          6 frames
row 1  run right     8 frames
row 2  run left      8 frames
row 3  wave          4 frames
row 4  jump          5 frames
row 5  failed        8 frames
row 6  hover         6 frames
row 7  running       6 frames
row 8  review        6 frames
row 9+ optional extra rows

The handmade pets in the gallery use an 8 × 11 sheet (1536 × 2288 pixels). Remix one to see a working example.

Codex pet sheets

Codex pet spritesheets use the same 192 × 208 cells in an 8 × 9 grid, with the same row order, so they work with the default mapping. Upload the spritesheet.webp from a Codex pet and press Auto-detect.

Tips

• Keep the character's feet on the same baseline in every frame so it does not bob.
• Use a transparent background.
• Empty cells at the end of a row are fine: set that move's frame count to the cells you used.
