Finite state machines are one of the most reliable ways to build clear, maintainable gameplay logic. State Designer brings that workflow into a modern, data-oriented architecture built on Unity DOTS, giving you the flexibility to create scalable systems for gameplay, AI, interactions, UI flow, and more.

No DOTS expertise is required. State Designer supports GameObject, hybrid, and Entities-based workflows, so you can use the approach that fits your project today while keeping a path open for higher-performance data-oriented execution as your project grows.

By combining visual state machine authoring with a DOTS-backed runtime, State Designer keeps logic organized while reducing runtime overhead. The result is a workflow that feels intuitive to build with and remains efficient and predictable as complexity increases.

🧠Why Finite State Machines?

State machines excel at modeling systems with clear phases, transitions, and event-driven behavior. They are a natural fit for gameplay systems, character abilities, interactable objects, UI flows, and cutscenes.
