Flow Core

Build Gameplay Logic You Can See

Create readable visual gameplay systems in Unity and move from a working Flow into the capability your project needs.
Explore a working Flow Build your first Flow Play Online Demo

Who this guide is for

Built for developers who already know the Unity Editor and want a practical path into Flow Core without needing prior Flow Core or C# experience.

Start with an outcome

Run something that already works, create one visible result, then move into the capability your project needs.

Explore a Working Flow Run the supplied Flow example and trace a visible event through its graph. Build Your First Flow Make a Cube grow when Play Mode starts by combining a graph, process, Blackboard, Trigger, and Action. Choose Your Next Path Select the Flow Core capability that matches the system you need to build.

One foundation, several systems

Flow Core separates authored behavior from runtime ownership. A Flow Graph stores the logic you can see. A FlowCoreProcess runs an instance of that graph on a scene object. Blackboards provide typed data, while Triggers and Entries decide when execution starts.

The same foundation supports event flows, FSM states, Behavior Trees, Stacks, GOAP planning, characters, animation, cameras, interactions, stats, effects, and C# integrations. Begin with one visible result, then follow the capability that matches your project.

Understand what runs

Use Flow Core in Five Concepts for the complete mental model, or go to Debugging Running Graphs when an authored result does not behave as expected.
