Play, Pause and Stop animation take the animation on a port instead of a fixed setting, fed by the new Animation literal or a list item tagged `$animation`. Playing an animation already running keeps its frame but counts it as started last, so turning back to a walk that never stopped shows that walk. The actor demo walks through one Play animation over `ItemAt(walk, facing)` again and stops every animation to stand. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
