Create a new simple Custom C# node#

You can create a Custom C# node to run your own custom logic in a Script Graph. For more information on Custom C# nodes, see Custom C# nodes.

To create a new simple Custom C# node:

1. [!includeopen-project-window]

2. Right-click a folder in the Project window's folder list, or anywhere in the Project window's preview pane, and go to Create > C# Script.

3. Enter a name, such as MyNode, for the new script file.

4. Press Enter.

5. [!includeopen-new-external-code]

6. In your external editor, copy and paste the following code into your C# script:

   using Unity.VisualScripting;
   using UnityEngine;
   
   public class MyNode : Unit
   {
      protected override void Definition() //The method to set what our node will be doing.
      {
      }
   }
   

7. [!includesave-script]

8. [!includereturn-unity]

9. [!includeregen-node-library]

   NOTE

   If you don't regenerate your Node Library, the node won't appear in Visual Scripting's fuzzy finder.

10. Open a Script Graph where you want to add your new node.

11. [!includeopen-fuzzy-finder]

12. The node appears as My Node at the end of the fuzzy finder list. Select the node to add it to your graph.

After you create the basic start to a node and add it to Visual Scripting's fuzzy finder, add ports so your node can send and receive data.
