Custom Nodes

Creating a custom node for Logic is as easy as creating a new C# file.
  1. 1.
    Simply right click in the project view and select: Create / Databrain / Logic / New Node
  2. 2.
    Name the node
  3. 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);
}
}
}
