CSS/JS Sprite Animation Tips: Smooth Pointer Tracking and Compression
jh3yy · x · 2026-08-11
Developer jh3yy shares practical tips for sprite animation with CSS and JS:
- Quick generation: generate a video from a character map, then use ffmpeg to split frames and create a sprite sheet (compress it, no need for a 3MB file).
- Smoothing: track pointer position and eased position; the eased position plays catch-up for smooth motion.
- Use CSS translate based on pointer position, with a blink animation included.
