UnityNodeEditorCore

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.

UNEC is ideal as a base for custom state machines, dialogue systems, decision makers etc.

Key features of UnityNodeEditorCore:

• Lightweight in runtime
• Very little boilerplate code
• Strong separation of editor and runtime code
• No runtime reflection (unless you need to edit/build node graphs at runtime. In this case, all reflection is cached.)
• Does not rely on any 3rd party plugins
• Custom node inspector code is very similar to regular custom inspector code

Node example:

[System.Serializable]
public class MathNode : Node {
    [Input] public float a;
    [Input] public float b;
    [Output] public float result;
    public enum MathType { Add, Subtract, Multiply, Divide}
    public MathType mathType = MathType.Add;
    
    public override object GetValue(NodePort port) {
        if (port.fieldName == "result") {
            float a = GetInputFloat("a");
            float b = GetInputFloat("b");
            switch(mathType) {
                case MathType.Add: return a + b;
                case MathType.Subtract: return a - b;
                case MathType.Multiply: return a * b;
                case MathType.Divide: return a / b;
            }
        }
        return 0f;
    }
}
