• Node should implement INode, IReceiver interfaces
• Node input or output should be set in the setup() function.

• 100% functionnal nodes should be in inside one of the following namespaces: Constellation.Math, Constellation.UI, Constellation.Unity, Constellation.BasicNodes, Constellation.Physics.
• Incomplete and test nodes should be inside Constellation.ExperimentalNodes. and be setted inside experimental node factory.

Stock nodes should use one of the node Factory to be instantiated and should be set inside the one linked to it's namespace. Ex: You create a MousePosition.cs class you should add it to Constellation.Unity namespace and instantiate it inside UnityNodeFactory.cs

namespace Constellation.ExperimentalNodes{
    public class Example: INode, IReceiver{
        private ISender sender;
        private Attribute attribute;
        public const string NAME = "Example";

        public void Setup (INodeParameters _node, ILogger _logger) {
            var wordValue = new Variable ();
            _node.AddInput (this, false, "Cold input example");
            _node.AddInput (this, true, "Warm input example");
            sender = _node.AddOutput (false, "Current setted word");
            attribute = _node.AddAttribute (wordValue.Set("My default value"), Attribute.AttributeType.ReadOnlyValue, "");
        }

        public string NodeName () {
            return NAME;
        }

        public string NodeNamespace () {
            return NameSpace.NAME;
        }

        public void Receive (Variable _value, Input _input) {
            if (_input.InputId == 0)
                attribute.Value.Set (_value);

            if (_input.InputId == 1)
                sender.Send (attribute.Value, 0);
        }
    }
}

Variable is very simillar to javascript variables. It basically do conversions for you so you don't have to worry about type in the editor. Variable has 4 types;

• number
• string
• bool
• object
• Variable[]

new Variable();

Set an empty variable.;

new Variable(0); var variable = new Variable(); variable.Set(0);

Set a number variable

var variable = new Variable("my string"); variable.Set(0);

On the first line variable is a string and on the second one it become a float
