What Is Visual Scripting in Unity?


Angela Bailey

Visual scripting is a powerful feature in Unity that allows game developers to create and manage game logic without writing code. It provides a user-friendly interface that enables you to visually connect nodes representing actions, conditions, and events to create gameplay mechanics, AI behavior, and more. In this article, we will explore what visual scripting is all about and how it can benefit your game development process.

Why Use Visual Scripting?

If you’re new to game development or come from a non-programming background, visual scripting can be a great starting point. It provides an intuitive way to create complex behaviors without the need for traditional coding knowledge. It allows artists, designers, and other team members to actively participate in the development process by creating and modifying game logic themselves.

Getting Started with Unity’s Visual Scripting

To begin using visual scripting in Unity, you need to install the Bolt add-on package from the Unity Asset Store. Bolt is a widely-used visual scripting tool that integrates seamlessly with Unity’s editor. Once installed, you can open the Bolt Graph window by navigating to “Window” > “Bolt” > “Graphs.”

The Bolt Graph Window

The Bolt Graph window is where you will spend most of your time when working with visual scripting in Unity. It consists of three main sections: the graph view, the variables panel, and the inspector panel.

  • The graph view: This is where you build your visual scripts by connecting nodes together. Nodes represent actions (e.g., spawning an object), conditions (e., checking if an enemy is within range), or events (e., player input).
  • The variables panel: Here, you can define and manage variables that store data values used in your scripts.

    You can create variables of various types, such as integers, floats, booleans, strings, and more.

  • The inspector panel: This panel provides detailed information about the currently selected node or variable. You can modify properties and settings directly from here.

Creating Visual Scripts with Bolt

To create a visual script in Bolt, you start by adding nodes to the graph view. You can do this by right-clicking on the graph canvas and selecting the desired node from the context menu. Nodes are categorized into different groups for easy navigation and organization.

Once you have added nodes to your graph, you can connect them together by dragging from one node’s output port to another node’s input port. This establishes a flow of execution between nodes.

Each node represents a specific action or condition. For example, you might use a “Spawn Object” node to create an enemy character when certain conditions are met. You can customize each node’s properties and settings through the inspector panel.

Benefits of Visual Scripting

Visual scripting offers several advantages for game development:

  • No coding required: With visual scripting, you can create complex game logic without writing code.
  • User-friendly interface: The drag-and-drop nature of visual scripting makes it accessible to artists, designers, and other non-programmers.
  • Rapid prototyping: Visual scripting allows for quick iteration and experimentation during the early stages of development.
  • Collaboration-friendly: Multiple team members can work on visual scripts simultaneously, speeding up development time.


In conclusion, visual scripting in Unity is a powerful tool that enables game developers to create and manage game logic without writing traditional code. It provides an intuitive and user-friendly interface, making it accessible to non-programmers and facilitating collaboration within development teams. By leveraging visual scripting, you can unleash your creativity and build complex gameplay mechanics more efficiently.
