创建编辑器文件

[CreateAssetMenu(menuName = "Emilia/Examples/Test")]
public class TestAsset : EditorUniversalGraphAsset { }

创建节点

public abstract class TestBaseNodeAsset : UniversalNodeAsset { }
public abstract class TestBaseNode : UniversalEditorNodeView { }


//TestNodeAsset是继承ScriptableObject的需要单独一个文件并且文件名和类名匹配

[NodeMenu("测试节点")]
public class TestNodeAsset : UniversalNodeAsset { }

[EditorNode(typeof(TestNodeAsset))]
public class TestNode : UniversalEditorNodeView { }

给编辑器文件添加特性NodeToEditor

[CreateAssetMenu(menuName = "Emilia/Examples/Test"), NodeToEditor(typeof(TestNodeAsset))]
public class TestAsset : EditorGraphAsset { }

完成上述步骤 右键菜单CrateNode可以创建刚刚写的测试节点

创建端口

[EditorNode(typeof(TestNodeAsset))]
public class TestNode : TestBaseNode
{
    public override List<EditorPortInfo> CollectStaticPortAssets()
    {
        List<EditorPortInfo> portAssets = new List<EditorPortInfo>();

        EditorPortInfo inputPort = new EditorPortInfo();
        inputPort.id = "Input";
        inputPort.direction = EditorPortDirection.Input;
        portAssets.Add(inputPort);

        EditorPortInfo outputPort = new EditorPortInfo();
        outputPort.id = "Output";
        outputPort.direction = EditorPortDirection.Output;
        portAssets.Add(outputPort);

        return portAssets;
    }
}
