xNode - A general purpose node editor

NodeEditor.GetEditor(myNode, NodeEditorWindow.current);

Heights are calculated dynamically from the contents of the node. For convenience the sizes (including width) is stored in NodeEditorWindow.current.nodeSizes. Note that these values can be one frame behind due to the values updating after the node draws.

What you're doing looks correct. Maybe the problem is with serialization? Try calling serializedObject.Update after connecting the ports

This isn't really xNode related. Try https://docs.unity3d.com/ScriptReference/SerializedProperty-arraySize.html

 

hi Siccity ,Is there any way I can use xNode without scriptableobject but like a EditorWindow open from menu?

 

You can possibly open the window using [MenuItem] attribute on a static function that opens the NodeEditorWindow, but you won't get far without ScriptableObjects, as that's the cornerstone of xNode

 

fine,thanks for your helping!

 

Hi,

loving the tool so far, but duplicating nodes doesn't seem to work properly if using scene graphs, since the scriptable object is being serialized in the monobehaviour it sits on, which Unity then claims is not persistent.



Interestingly enough, selecting multiple nodes (or a single one) still lets me duplicate ONE node.

Anyone have any input on this?

 

Hi Siccity

I am trying to change the color of a node based on a boolean that is instantiated on the node.
Essentially when the boolean is set to true, I want the node to be blue.
When it is set to false, I want the node to be red.

I see GetBodyStyle on NodeEditor, and I created my own custom Texture and GUIStyle in NodeEditorResources.

I was having trouble checking a variable on the node at the time the node's GUIStyle is chosen/updated.

I was initially focusing in the NodeEditorGUI script in the DrawNodes function.
I was not having much luck though.

Any insight?

 

Hi, thank you for the awesome features this system provides!

I would like to use Odin serialized fields inside a node: I made the XNode.Node inherit from SerializedScriptableObject (Sirenix) instead of the Unity counterpart and it just works flawlessly with one exception, Output/Input fields.

If I try to use the Output attribute along with the combo <NonSerialized, OdinSerialize> attributes on a field then the target object obtained from the serialized property passed to the PropertyField (NodeEditorGUILayout) method results in a null element when casted to XNode.Node.

I tried to adapt the code to work but I'm not enough familiar with serialization, drawers etc.
So, is there a way to make Odin Serialized fields work as Output(s)?

This is the output field declaration:

Code (CSharp):

1. [NonSerialized, OdinSerialize, Output(dynamicPortList = true)] public Choice[] choices;

- Choice is a Serializable Class with no inheritance which uses fields which cannot be serialized by Unity (Odin can serialize such fields)
- if the Output attribute is removed, the field is correctly displayed/serialized but the output ports are not displayed
- if OdinSerialize or NonSerialized attribute is removed, the field won't be serialized/showed correctly but the output ports are displayed

This is the error displayed in console:

Spoiler

Is this a known issue? Reorderable list of strings causes issues with two or more nodes.

 

Thank you for such a great node editor Thor.

You inspired me to release my first project for free on GitHub.

Hey! @Siccity, first of all thank you for this magnificent piece of art. I'm using XNode for my graph solution because offer the max flexibility in less time possible.

I was wrapping my head in this thing:



How did you put the icons inside? I didn't find any example in the internet.
I Was trying to do it with Horizontal Layout but without success... Any tips?

 

I did not make that, but you can use https://docs.unity3d.com/ScriptReference/GUI.DrawTexture.html and supply your own rect coordinates, placing it anywhere

 

Hey. Thanks for xnode. Using this for my own dialogue solution, works great. However it's not very fast. if I would grow the dialogue even more it gets lower than 2 fps. What would be a way to optimize it? Amplify Shader seems similar and has no optimization issues

 

Mmm odd I have much more complex scenes which also have some nodes with custom inpsector that creates meshes every frame and draws them in a node and not seeing any real slow down. What are your system specs?
