What problem does it solve? Animating game object properties frame-by-frame by hand is error-prone and verbose. This Skill provides the complete Phaser 4 tween API so you can move, fade, scale, and rotate objects with declarative configuration instead of manual update loops. ## Core Features & Use Cases - Property Tweening: Animate any numeric property on Game Objects or plain objects with absolute, relative, array, or function-based values, plus per-property overrides. - Sequencing and Timing: Build tween chains, apply stagger offsets across multiple targets, and control yoyo, repeat, loop, hold, and delay behavior. - Easing and Control: Use the full easing library (Quad through Bounce, Stepped, custom functions) and manage playback with pause, seek, restart, timeScale, and killTweensOf. - Use Case: You want a coin to bob up and down forever and a score counter to tick from 0 to 100. Use a yoyo repeat tween for the coin and addCounter with onUpdate for the counter. ## Quick Start Ask the AI to add a Phaser tween that moves a sprite to x 600 over two seconds with Sine easing and a completion callback.
