Unity Visual Scripting
Unity Visual Scripting is a node-based visual programming system within the Unity game engine that allows developers to create game logic and behaviors without writing traditional code. It uses a drag-and-drop interface where nodes represent functions, variables, and events, connected by wires to define flow and data. This tool is integrated into Unity's editor and supports both Unity's built-in visual scripting system (formerly Bolt) and third-party solutions like PlayMaker.
Developers should learn Unity Visual Scripting when working on rapid prototyping, educational projects, or collaborating with non-programmers like artists and designers, as it lowers the barrier to entry for game logic creation. It's particularly useful for indie developers or small teams who need to iterate quickly without deep coding expertise, and for creating simple mechanics, UI interactions, or event-driven systems in 2D/3D games. However, for complex, performance-critical projects, traditional C# scripting is often preferred.
