Basic concepts in Visual Scripting

Note

For versions 2019/2020 LTS, download the Visual Scripting package from the Unity Asset Store.

In this section, you can find information about basic concepts in Visual Scripting. These concepts will help you create logic for your application.

The interface

The Visual Scripting interface starts with the Graph window. For more information, see The interface.

Nodes

Nodes are the most basic part of creating scripts in Visual Scripting. For more information, see Nodes.

Graphs and Machines

Graphs contain the visual representations of logic in your application. To use a graph, you attach it to a Script Machine or State Machine on a GameObject. For more information about graphs, see Graphs. For more information about Script Machines and State Machines, see Script Machines and State Machines.

Variables

Variables act as a container for a piece of information that might change as your application runs. For more information, see Variables.

Object types

Variables, data, and objects in Visual Scripting all have a specific type. For more information, see Object types.
