--- pinned/animate_sprite

  {
    "description": "Animate an existing image into a sprite sheet: a walk cycle, an attack, a spinning coin. First create the source image (a facing still from create_character, or a transparent cutout), then pass it as referenceImage; the animation opens on that exact image so identity and facing stay locked. One call is one motion; for a directional character, animate once per facing and motion. An animation is one packed sheet.png plus a frames.json beside it giving the frame grid (frameWidth, frameHeight, cols, rows, count, padding), timing, and a 'rest' box: the subject's visible bounds in its resting pose. Slice frames from the grid, and size and ground the sprite by the rest box rather than the frame rectangle. A still has a one-frame .json beside it carrying its rest box. Takes a few minutes. Costs 5 units.",

'front' (straight-on, facing the viewer) is for interface art the game camera doesn't see — portraits, cards, splash art, item icons — and for games with no world camera (visual novel, card, quiz).",

It does not animate: pass a facing still to animate_sprite for each motion. Set directional:false for a sprite the game rotates in code (a car, an ant, a projectile). Costs 2 units.",

A transparent cutout gets a .json beside it carrying its rest box; size it by that box, since the visible art is smaller than the image. Tile textures in code rather than stretching one copy. For several items that share a frame use create_image_set; for anything that animates or needs facings use create_character. Costs 1 unit.",

One anchor image is drawn from sharedDescription and every item is matched to it, so the set shares one border, scale, and palette. Each item is written to <dir>/<name>.png. Not for unrelated subjects that merely share an art style (pass one styleReference to separate create_image calls for that). A new set needs at least two items; to add to an existing set, call again with the same dir and one or more items. Costs 1 unit per item plus 1 for a new set's anchor.",
