Physics-based motion principles (gravity, momentum, elasticity, resistance) make digital interfaces feel intuitive by matching users' subconscious expectations. Lottie Creator's State Machines let designers build interactive animations visually without code, mapping states like idle/hover/pressed to user triggers. An AI-powered 'Prompt to State Machines' feature lets designers describe interactions in plain language to auto-generate the logic. The exported .lottie file embeds all interaction logic and works out of the box on web, iOS, and Android. The post also advocates building a cohesive motion system with consistent easing curves and physics parameters rather than one-off animations.
