Why
Using SpriteAnimator (most noticeable with large) spritesheets sometimes results in sprite shaking. Looked at why that happens (at first was thinking sprite texture filtering...etc) it seems the
framesHandframesVcalculations have small precision issues which result in visual shake in the sprite as it's playing (since it's use to calculate the texture offsets). Simply rounding them solves the visual shake .Here is a small Codesandbox reproduction of the issue (Sandbox / Demo)
And here is a quick sandbox implementing the fix (Sandbox / Demo)
What
framesHandframesVinMath.round(since they can be suffer from decimal precision instability which makes the sprite shake)Checklist
