- reskate.animation.game_clips lists the game's animations and "game:<name>" plays one: the skater's Eclipse clips decoded from its data (Extension/AnimationStudio/game_clips, ported from ReSkate Studio's animation export), matching make_trick_library.py's clips. - reskate.animation.play's floor stands a clip on the floor where the skater is, its board's lowest point on it, as the pull request's studio did; the game's trick clips no longer sink. - Animator Studio lists the game's tricks from its data; the Python tools are gone.
