h3-game-sprites
Build 2D game sprite sheets by generating motion with MiniMax H3 (Hailuo) video, then cutting the footage into validated chroma-keyed sprite frames - the Mortal Kombat method with a video model instead of filmed actors. Covers the character-still recipe, the idle-pin trick that keeps every move on-model and loopable, per-move clip briefs, frame extraction with keying and numeric QC, seamless walk-cycle detection, and the atlas/render math that keeps a character planted and correctly sized in an engine. Use this whenever the user wants game sprites, a sprite sheet, an animated 2D game character
Why this score
Popularity score: 64/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank
Security
Scanned Oct 20, 2026 at commit d1295576a3de, with Cisco's open-source skill-scanner.
What its code does:
- Reads environment variables and sends network requests with them API clients do this to send your key to the service. Check which service it talks to.scripts/gen_still.py:42
- Makes network requestsscripts/gen_still.py:37 and 1 more
Web addresses in its code:
- openrouter.aiscripts/gen_still.py:18
These are the sites named in the code, so it's where your data could go. It isn't a complete list: code can build addresses while it runs, and a few of these may be links rather than calls. Whatever you send also goes to the AI model you use.
A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
