Is There Visual Scripting in Unity?

If you are a game developer or have any interest in game development, you have probably heard of Unity. Unity is one of the most popular game development engines out there, known for its flexibility and ease of use.

However, if you are new to Unity or game development in general, you might be wondering if there is a way to create games in Unity without writing code. In other words, is there visual scripting in Unity?

What is Visual Scripting?

Visual scripting is a method of creating scripts or programming logic using visual elements rather than traditional text-based coding. Instead of writing lines of code, developers can create scripts by connecting nodes or blocks that represent different functions or actions.

This approach to programming offers several advantages. It allows people with little or no coding experience to create complex behaviors and interactions in their games. It also provides a more visual and intuitive way of understanding and debugging code.

Unity’s Visual Scripting Solution: Bolt

If you are looking for visual scripting capabilities in Unity, look no further than Bolt – the official visual scripting solution provided by Unity Technologies.

Bolt is a powerful yet user-friendly visual scripting tool that allows you to create gameplay mechanics, AI behavior, UI interactions, and much more without writing a single line of code.

Getting Started with Bolt

To start using Bolt, you need to install it first. Open up your Unity project and navigate to the Package Manager window. Search for “Bolt” and click on the “Install” button next to it.

Once installed, you can access Bolt by going to the Window menu and selecting “Bolt Visual Scripting.” This will open up the Bolt Editor window where all your visual scripting magic will happen.

Creating Visual Scripts with Bolt

In Bolt, visual scripts are called graphs. A graph consists of nodes that represent different functions or actions, and connections between these nodes indicate the flow of execution.

To create a new graph, simply right-click in the Bolt Editor window and select “Create Graph.” Give your graph a name and start building your script by adding nodes from the sidebar.

Bolt provides a wide range of nodes for various purposes such as math operations, object manipulation, input handling, and more. To add a node to your graph, simply drag it from the sidebar and drop it onto the canvas.

Node Connections

Once you have added nodes to your graph, you can connect them together by dragging a connection from one output port to another input port. This connection represents the flow of data or execution between nodes.

For example, if you want to move an object when an event occurs, you can connect an event node (such as “On Button Clicked”) to a transform node (such as “Translate”). This way, when the event is triggered, the object will move according to the specified translation values.

Variables and Functions

Bolt also allows you to create variables and functions within your visual scripts. Variables can store data that can be accessed and modified throughout your script. Functions allow you to encapsulate reusable pieces of code for better organization and modularity.

To create a variable or function in Bolt, right-click on an empty space in your graph canvas and select “Create Variable” or “Create Function” respectively. Give them meaningful names and define their properties or parameters using the context menu.

Debugging Your Visual Scripts

Bolt provides several debugging tools to help you identify and fix issues in your visual scripts. You can use the Debug Log node to print messages to the console, the Breakpoint node to pause execution at a specific point, and the Inspector window to inspect variable values during runtime.


Visual scripting is a powerful tool that allows game developers of all skill levels to create complex gameplay mechanics without writing code. Unity’s visual scripting solution, Bolt, provides an intuitive and visually engaging way of creating scripts in Unity.

Whether you are a beginner or an experienced developer looking for a more visual approach to programming, Bolt is definitely worth exploring. So go ahead, unleash your creativity, and start building amazing games with visual scripting in Unity!
