Strongly-Typed Gameplay Workflows for Unity

Flow Core is a production-grade visual workflow framework for Unity. It helps teams build gameplay logic, character behavior, interaction systems, and reusable game features through strongly-typed graphs and code-first extension points.

Flow Core is not designed to hide architecture behind visual scripting. It is designed to make gameplay systems easier to author, inspect, extend, and maintain without giving up type safety, runtime performance, or clear ownership of game logic.

BLASTFALL — Playable Game Showcase

See Flow Core in action in BLASTFALL, a Unity browser game about charging shots, knocking down structures, revealing hidden cats, and chasing a higher score.

BLASTFALL uses Flow Core to orchestrate input, charging, firing, and round progression. Custom Instructions and Conditions connect the graphs to focused C# gameplay components, while shared Blackboard settings support gameplay tuning. It shows how visual event flows and reusable code work together in a growing game project.

What Flow Core Is For

🔗 Visual Gameplay Logic

Create readable gameplay flows with explicit execution paths, typed inputs, conditions, instructions, and reusable logic blocks.

Use Flow Graphs when behavior needs to be visible, testable, and easier to reason about across design and engineering workflows.

🧠 Strongly-Typed Runtime Data

Use the Blackboard to store and access runtime data through explicit typed keys.

Flow Core favors predictable data access, clear extension points, and low-overhead runtime behavior over loosely-typed convenience systems.

🧍 Modular Character Systems

Flow Character provides a structured way to build character-facing gameplay features.

Use it to compose movement, control, interaction, animation-related behavior, and character-specific modules without turning every character script into a single oversized component.

🤝 Interaction-Driven Gameplay

Flow Interaction helps define how characters, objects, and gameplay rules meet.

Use it for reusable interaction logic such as selecting valid targets, checking conditions, triggering instructions, and connecting world objects to character behavior.

🧩 Code-First Extensibility

Flow Core is built for programmers who want visual authoring without losing control of the underlying system.

Create custom nodes, instructions, conditions, blackboard value types, persistence handlers, gameplay modules, and editor integrations through supported extension surfaces.

Design Principles

✅ Strong Types First

Flow Core avoids treating all gameplay data as generic objects. Typed data contracts make systems easier to debug, extend, and optimize.

⚙️ Runtime Performance Matters

Visual authoring should not mean careless runtime cost. Flow Core is designed around explicit execution, reusable data paths, and predictable runtime behavior.

🛠 Built for Framework Authors

Flow Core is not only a tool for assembling gameplay logic. It is a foundation for building higher-level gameplay frameworks, including Flow Graphs, Character modules, Interaction systems, Behavior Trees, FSMs, GOAP workflows, and custom project-specific systems.

🔍 Visual Does Not Mean Hidden

Flow Core keeps architecture visible. Graphs, modules, conditions, instructions, and runtime data are meant to make system behavior easier to inspect, not harder to understand.

Where To Start

If you are new to Flow Core, start with the core workflow:

1. Learn how Flow Graphs execute logic.
2. Understand how the Blackboard stores typed runtime data.
3. Build a simple gameplay flow with conditions and instructions.
4. Add Character behavior when logic belongs to a character.
5. Add Interaction behavior when logic depends on objects, targets, or player-world relationships.
6. Extend the system with custom code when your project needs reusable gameplay building blocks.

Who Flow Core Is For

Flow Core is for Unity developers who need more than a simple visual scripting layer.

It is intended for teams building maintainable gameplay systems, reusable framework features, designer-facing authoring tools, and project-specific gameplay architecture that must remain understandable as the project grows.
