Animation Rows

The Codex app reads one fixed atlas: 8 columns, 9 rows, 192x208 pixels per cell.

Row State Used columns Durations
0 idle 0-5 280, 110, 110, 140, 140, 320 ms
1 running-right 0-7 120 ms each, final 220 ms
2 running-left 0-7 120 ms each, final 220 ms
3 waving 0-3 140 ms each, final 280 ms
4 jumping 0-4 140 ms each, final 280 ms
5 failed 0-7 140 ms each, final 240 ms
6 waiting 0-5 150 ms each, final 260 ms
7 running 0-5 120 ms each, final 220 ms
8 review 0-5 150 ms each, final 280 ms

Unused cells after each row's final used column must be fully transparent.

Row Purposes

  • idle: neutral breathing/blinking loop; use as the reduced-motion first frame.
  • running-right: locomotion to the right; 8-frame loop should read directionally.
  • running-left: mirrored or redrawn locomotion to the left; do not simply reuse right-facing frames unless the design is symmetric.
  • waving: greeting or attention gesture; clear start, raised gesture, return.
  • jumping: anticipation, lift, peak, descent, settle.
  • failed: error/sad/deflated reaction; readable but not visually noisy.
  • waiting: patient idle variant; glance, small bounce, or prop motion.
  • running: generic/front-facing or in-place run loop.
  • review: focused/inspecting/thinking loop suitable for review state.
