Visual scripting

Visual scripting in Unity empowers creators to develop gameplay mechanics or interaction logic with a visual, graph-based system, instead of writing traditional lines of code.


Want to get started with visual scripting as quickly as possible? This quick-start tutorial introduces the basics of visual scripting to help you make your own games with node-based logic.

Visual scripting in Unity helps team members create scripting logic with visual, drag-and-drop graphs instead of hand-writing code. It also enables more seamless collaboration between programmers, artists, and designers for faster prototyping and iteration.


デザイナーとアーティストにとって、Unity でアイデアをテストし、変更を加え、作品をもっと直接的に制御するための優れた選択肢です。また、プログラマー以外のユーザーも、技術知識のあるチームメンバーが作成したノードグラフを活用できます。



Using a visual scripting system can increase the speed of prototyping and testing for developers, avoiding wasted effort on handwritten code for ideas that might not be viable. Visual scripting is also a great way to make existing scripts more accessible or create tools for use by other members of a development team.





ステートグラフを使用すると、特定の状態になったときに実行するアクションをオブジェクトに指示する、自己完結した動作を作成できます。ステートグラフは、AI の動作やシーンまたはレベルの構造、状態間で遷移する動作が必要とされるシーンのあらゆる側面に適しています。


Make changes to graphs in Play Mode to see visual scripting updates in real-time. This offers a much faster way to iterate and test ideas without needing to recompile project changes.


Predict and indicate nodes that will crash before you even press play, and analyze your graphs to anticipate missing components or null references. If an error occurs at runtime, visual scripting will pinpoint its source by highlighting it in the graph.


Visual scripting is designed to be accessible for less technical creators through user-friendly naming conventions, commenting and grouping features that keep graphs simple to read, and the Fuzzy Finder, which makes it easy to search for what you need.


Use a method, field, property, or event from Unity, any third-party plugin, or even custom scripts within your graphs. Visual scripting directly accesses your codebase via reflection and is always up to date.



Visual scripting is a graphical way to manipulate objects and behaviors in Unity without hand-writing code. The logic is built by connecting visual nodes together, empowering artists, designers, and programmers to create gameplay and interactive systems in a simple way.

How can I access visual scripting?

From the 2021.1 release and onward, visual scripting is included in the Package Manager, and shipped with the Unity Editor.

For 2019 LTS and 2020 LTS releases, Bolt Visual Scripting can be found on the Unity Asset Store to download for free.

Unity アセットストアとは何ですか?

The Unity Asset Store is a marketplace with thousands of free or affordably priced assets that save time and effort for Unity creators. It is a powerful resource for successful Unity developers that offers over 60,000 packs featuring tools and Editor extensions, 3D and 2D art, cinematic quality music and sound effects, and more.

What versions of Unity does Bolt Visual Scripting support?

Bolt Visual Scripting will continue to support projects on Unity 2018, 2019, and 2020 LTS versions.

Unity でのビジュアルスクリプティングはどのように進化していきますか?

From the 2021.1 release and onwards, Unity will provide visual scripting as a core feature, included with the Unity Editor by default.

What about DOTS-based visual scripting?

Unity is in the process of evaluating the future of visual scripting in consideration of Bolt, Bolt 2, and our DOTS-based visual scripting solution. Our goal is to create a single, cohesive solution that does not result in broken features or fractured communities, and that meets user expectations around production-readiness.
