Support xNode on Ko-fi or Patreon

xNode

Thinking of developing a node-based plugin? Then this is for you. You can download it as an archive and unpack to a new unity project, or connect it as git submodule.

xNode is super userfriendly, intuitive and will help you reap the benefits of node graphs in no time. With a minimal footprint, it is ideal as a base for custom state machines, dialogue systems, decision makers etc.

Installing with Unity Package Manager

(Requires Unity version 2018.3.0b7 or above)

To install this project as a Git dependency using the Unity Package Manager, add the following line to your project's manifest.json:

"com.github.siccity.xnode": "https://github.com/siccity/xNode.git"

You will need to have Git installed and available in your system's PATH.

If you are using Assembly Definitions in your project, you will need to add XNode and/or XNodeEditor as Assembly Definition References.

Node example:

// public classes deriving from Node are registered as nodes for use within a graph
public class MathNode : Node {
    // Adding [Input] or [Output] is all you need to do to register a field as a valid port on your node 
    [Input] public float a;
    [Input] public float b;
    // The value of an output node field is not used for anything, but could be used for caching output results
    [Output] public float result;
    [Output] public float sum;

    // The value of 'mathType' will be displayed on the node in an editable format, similar to the inspector
    public MathType mathType = MathType.Add;
    public enum MathType { Add, Subtract, Multiply, Divide}
    
    // GetValue should be overridden to return a value for any specified output port
    public override object GetValue(NodePort port) {

        // Get new a and b values from input connections. Fallback to field values if input is not connected
        float a = GetInputValue<float>("a", this.a);
        float b = GetInputValue<float>("b", this.b);

        // After you've gotten your input values, you can perform your calculations and return a value
        if (port.fieldName == "result")
            switch(mathType) {
                case MathType.Add: default: return a + b;
                case MathType.Subtract: return a - b;
                case MathType.Multiply: return a * b;
                case MathType.Divide: return a / b;
            }
        else if (port.fieldName == "sum") return a + b;
        else return 0f;
    }
}
