Custom Nodes

Creating a custom node for Logic is as easy as creating a new C# file.

1. Simply right click in the project view and select: Create / Databrain / Logic / New Node

2. Name the node

3. Done

You can of course also just create a new class file and derive from NodeData

using Databrain.Logic.Attributes;

namespace Databrain.Logic
{
    [NodeTitle("My Node")]
    [NodeCategory("Custom")]
    [NodeOutputs(new string[] {"Out"})]
    [NodeDescription("This is a node description")]
    public class MyNode : NodeData
    {
        public override void ExecuteNode()
        {
            // Execute code there
        
            // Execute next node connected to output index 0
            ExecuteNextNode(0);
        }
    }
}
