0.1.0 / published Aug 19, 2026 / repository
Load Aseprite assets into the Flock ECS engine. Parses native .aseprite/.ase files (binary: layers, cels with zlib-compressed or raw pixels, RGBA/grayscale/indexed color, linked cels, tags, slices, palette) by compositing every frame on the CPU, and the Aseprite JSON+PNG spritesheet export (frames, frameTags, slices, durations). Both feed a small animation layer: an AsepriteAnimation component + a system that plays tags (forward / reverse / ping-pong) by driving a Sprite's atlas UVs. The parser is pure Crystal and runs headless.
