Touch, Respond, Animate: Interactive Rive Awesomeness
summary
Rive state machines and runtime inputs (trigger, boolean, numeric, text) let animations respond to gestures and data binding and a new scripting beta makes behaviors dynamic; exported assets often shrink to 8 KB files versus multi‑MB Lottie JSONs because Rive uses flatbuffers, so first‑frame startup is faster. A purpose‑built C++ renderer offloads vector work to the GPU for smoother animation on watches and embedded screens. Production caveats: call riv native.init, avoid dynamic builds, dispose assets, use repaint boundaries and consistent naming.
