Implement a block node

This procedure assumes you have already implemented a context node, as described in Implement a context node.

To implement a block node:

  1. Define a class that inherits from the BlockNode base class
  2. Add the UseWithContext attribute to connect it to your context node

The resulting code looks like:


[UseWithContext(typeof(MyContextNode))]
[Serializable]
public class MyBlockNode : BlockNode
{
}

To relate a block node to several context nodes, list them separated with a comma in your UseWithContext attribute:


[UseWithContext(typeof(MyContextNode), typeof(MyOtherContextNode))]
[Serializable]
public class MyBlockNodeWithMultipleContexts : BlockNode
{
}

Block nodes inherit all features available in its parent Node class. Review Implement a node to learn how to customize your node with node options, ports, and orientation settings.
