Design interactive behavior as a graph, right inside your patch. Draw states, connect them with frame-timed transitions, and drop regions that broadcast when they're active — then wire it all into your visuals. Trigger transitions from anything in the patch, watch the active state, frame count, and transition countdown update live, and drive particles, scenes, or UI from a state machine you can actually see. No spaghetti, no guesswork — just a clean, node-based brain for your project.
