Does Unity Have Built in Visual Scripting?


Angela Bailey

Unity is a powerful game development engine that allows developers to create stunning and immersive experiences. One of the key features that sets Unity apart is its built-in visual scripting system, which enables developers to create complex gameplay mechanics and interactions without having to write code.

What is Visual Scripting?

Visual scripting, also known as node-based scripting or visual programming, is a method of creating scripts using a graphical interface instead of traditional text-based coding. Instead of writing lines of code, developers can visually connect nodes or blocks together to define the logic and behavior of their game or application.

Advantages of Visual Scripting

Visual scripting offers several advantages over traditional coding for certain types of projects:

  • Simplified Workflow: Visual scripting provides a more intuitive and streamlined workflow for designers and artists who may not have extensive programming knowledge.
  • Rapid Prototyping: With visual scripting, developers can quickly iterate on ideas and test out different gameplay mechanics without spending excessive time writing code.
  • Debugging Made Easier: Visual scripts often provide visual cues and indicators for debugging purposes, making it easier to identify and fix issues in the logic flow.

Unity’s Visual Scripting Solution: Bolt

In recent years, Unity has introduced its own official visual scripting solution called Bolt. Bolt is a powerful visual scripting system that is integrated directly into the Unity Editor. It provides an intuitive interface for creating complex gameplay mechanics using nodes and connections.

Bolt offers a wide range of pre-built nodes that cover various functionalities such as math operations, input handling, animations, physics simulations, and more. These nodes can be connected together to create custom behaviors with ease.

Key Features of Bolt

Bolt comes with several key features that make it a powerful tool for visual scripting:

  • Visual Editor: Bolt provides a clean and organized visual interface, making it easy to understand and navigate through complex scripts.
  • Custom Scripting: While Bolt is primarily a visual scripting tool, it also allows developers to write custom C# scripts within the visual environment, providing flexibility for more advanced users.
  • Live Editing: One of the standout features of Bolt is its live editing capabilities. Developers can make changes to their scripts in real-time while the game is running, allowing for quick iterations and immediate feedback.

How to Get Started with Bolt

If you are interested in exploring Unity’s visual scripting capabilities with Bolt, you can follow these steps to get started:

  1. Install Bolt: Open the Unity Editor and navigate to the Asset Store. Search for “Bolt” and click on the “Import” button to add it to your project.
  2. Create a Graph: Once Bolt is installed, you can create a new graph by right-clicking in your project window and selecting “Create > Visual Script > Graph”. This will create a new graph asset that can be opened and edited in the visual editor.
  3. Add Nodes: To start building your script, simply drag and drop nodes from the toolbox onto the canvas.

    Connect them together by dragging from one node’s output port to another node’s input port.

  4. Edit Node Properties: Each node has its own set of properties that can be modified to define its behavior. You can access these properties by selecting the node and inspecting the inspector window.
  5. Test and Iterate: Once you have built your script, you can test it out by running your game in the Unity Editor. Make adjustments as needed and iterate on your design until you achieve the desired result.


Unity’s built-in visual scripting solution, Bolt, provides a powerful and intuitive way for developers to create complex gameplay mechanics and interactions without having to write traditional code. With its visual editor, live editing capabilities, and extensive library of pre-built nodes, Bolt offers a streamlined workflow for designers and artists to bring their ideas to life.

If you are looking to dive into visual scripting in Unity, give Bolt a try. Start experimenting with its features and unleash your creativity in building amazing games and interactive experiences.
