Sprite Animation Generator

Why sprite animation is hard to generate

An animation is a set of frames that must agree with each other: the same character, the same size, the same ground line. Generating frames one by one breaks all three, and the result flickers.

SpriteDock plans a starting pose for each move, aligns it to the character's feet, generates the frames from that pose on one sheet, and registers each frame back to the pose. A jump keeps its arc; grounded moves keep their feet down.

How it works

1. Describe the characterOne line is enough: who it is, what it wears, side view. SpriteDock paints it on the grid in your palette.
2. Pick its movesIdle, walk, run, jump and attack, as one Platformer set. Each starts from its own pose, aligned to the character's feet.
3. Export for your engineDownload frames, a sheet with atlas JSON, GIFs, an Aseprite file, or Godot, Unity and Phaser files.

What you download

• PNG framesEvery frame as its own transparent PNG, at the sprite's real resolution.
• Sprite sheet + atlas JSONOne uniform-cell sheet and a JSON map of every frame and animation.
• GIF previewsEach animation as a looping GIF, for a devlog or a store page.
• Aseprite fileAn .aseprite with your palette embedded and one tagged clip per animation.
• Godot SpriteFramesA .tres resource beside the sheet: set it on an AnimatedSprite2D.
• Unity clipsThe sheet's .meta, already sliced with point filtering, and one .anim per animation.
• Phaser 3 atlas + animationsA Phaser 3 JSON atlas of every frame and a JSON of every animation, beside the sheet.
