[Released] uNode - Visual Scripting [Support C# Import/Export]

Thank you! At this moment dialog box not show up but its freeze anyway (now its look freeze less than before)

Screen:
https://prnt.sc/20u0pz0 (i just try to add float)

Maybe its because of unity... i have power CPU (i7 10gen) and GPU, dont know why its happen.

 

Hmm it's weird, never seen this before. Do you have error in the console? and do you have a lot of assets?

 

No errors, project quite simple
In this project few assets

Screen:
https://prnt.sc/20u30xa

In this case i just pressed - apply
Screen: https://prnt.sc/20u3hhx (sorry for phone pic, freeze again)

Console:
Screen: https://prnt.sc/20u3kjy

Looks like crazy, every action hit so hard

UPD
Change version to 2020.3.23 (not help).

 

Can you try only uNode with empty project?
Or can you use 'Profiler' to see what's causing the lag/freeze.
In my machine it work with 2019.4, 2020.3, and 2021.1 and doesn't take much of RAM.

 

i have the same issue without unode. its something in unity i guess. in 2021 memory high but it resets sometimes. but this version buggy so i stopped on 2019. but profile maybe im wrong

 

Is there way to use OnDrawGizmos and OnDrawGizmosSelected in uNodeRuntime graph(run in editor).

 

Hmm look weird since i don't have such a problem, if you can please use Memory Profiler and use 'Take Sample Editor' and send the result here.
something like this:

-Open uNodeRuntime.cs and add this code bellow into that script:

Code (CSharp):

1.  
2.        void OnDrawGizmos() {
3.            var func = GetFunction("OnDrawGizmos");
4.            if(func != null) {
5.                if(runtimeBehaviour != null) {
6.                    //Invoke for native c# script.
7.                    runtimeBehaviour.InvokeFunction("OnDrawGizmos", null);
8.                    return;
9.                }
10.                //Invoke for reflection or in editor.
11.                func.Invoke(null);
12.            }
13.        }
14.  
15.        void OnDrawGizmosSelected() {
16.            var func = GetFunction("OnDrawGizmosSelected");
17.            if(func != null) {
18.                if(runtimeBehaviour != null) {
19.                    //Invoke for native c# script.
20.                    runtimeBehaviour.InvokeFunction("OnDrawGizmosSelected", null);
21.                    return;
22.                }
23.                //Invoke for reflection or in editor.
24.                func.Invoke(null);
25.            }
26.        }
27.  

 

i have tried and does not work for me.

 

Are you sure the graph is uNodeRuntime or maybe you hide the uNodeRuntime gizmos?
The code only work for uNodeRuntime graph, Class Component graph doesn't work with this.

 

i have tried and it work now, there were a bug in current unity version i have(2021.2.4f1). if you try to assignee color gizmos will not draw at all.for example.

in this case Gizmo will not draw:

Code (CSharp):

1.     public Color c;
2.  
3.  
4.     public void OnDrawGizmos()
5.     {
6.         Gizmos.color = c;
7.         Gizmos.DrawWireSphere(transform.position, 1f);
8.  
9.     }

or



but if you don't change color will work:

Code (CSharp):

1.     public Color c;
2.  
3.  
4.     public void OnDrawGizmos()
5.     {
6.         Gizmos.DrawWireSphere(transform.position, 1f);
7.  
8.     }

thx for your support.

 

I think it is because the color is transparent, try to change to change the color alpha value. It should work.

 

thx, definitely you are right.

 

got that memory overload even on 2019 ver too. memory gather over time during hour or more. tried to use profiler but it hang unity. so Wahid cant do anything with this info )

 

I think i found the problem, it is because of Texture2D. But still don't know where it come from, i still investigate it.

 

After investigating, i found that it was the uNode Logo icon that take so much of memory. I don't know why the icon is loaded many time as i only load it once using the script but i think it is loaded when drawing Gizmos, Asset Icon, Hierarchy Icon, etc.
Then after i resize the icon size to 128x128 pixels the icon now only load 128kb in memory ( 34.5 MB before ).

Download and import the attached file to fix memory leak. If your memory usage is still too high after an hours or so, you can use menu 'Tools>uNode>Advanced>Reload Scripts' to free up some space in memory.

 

@wahid_rachmawan
I'm afraid to ask but...
What is the future of uNode?

 

Do you mean when the next update or the roadmap?

 

Yes, something like that.
(Simply put, is there any hope that uNode will still be supported in a year or two?)

 

Sure uNode still regularly updated, though the new version is in BETA and it is only available for tester in uNode discord.
New version have a lot of improvement and fixes, currently i still updating the documentation for preparing release the stable version. If you want to test a new version you can join our discord server here: https://discord.gg/8ufevvN and don't forget to DM me to access tester channel.

And here is the roadmap: https://trello.com/b/mlANnBPw/unode

 

Does uNode supports new input system? Like On Input System Event nodes in Bolt.

 

Currently uNode doesn't have a event for the new Input System ( it will be added ASAP) but you can getting input dirrectly from the new Input System : https://docs.unity3d.com/Packages/c...l#getting-input-directly-from-an-input-device
-You can parse the example code with C# Parse to test it.

And getting input indirrectly is only supported for c# graphs. This also can be tested by parsing example c# script from the Input System documentation page.

 

COOL. uNode is amazing.

 

That's great! Thank you, I imported package, hope its work!

And i can't solve one puzzle with spine! I need Flip image but its looks like no possible with unode (only if i do it manually in generated script).

i need this one:

[SerializeField]
private SkeletonMecanim _skeletonMec;
_skeletonMec.skeleton.FlipX = _flipPlayer;

but unodes only gives me this:

 

I think your graph is correct.

if you need this:
'private SkeletonMecanim _skeletonMec;'
Then you just need to create a new variable and make modifier to public for show the variable in inspector.
Or if you need the variable to private then add a 'SerializeField' in the attribute of the variable.

Here is my simple test graph ( tested and work ) :

I don't found a SkeletonMechaim type in my project so use SpriteRenderer instead.

 

Sorry for my describe. I know how to make [SerializeField].

off-topic: for me was not so oblivious how to make array =)





The problem here:
_skeletonMec.skeleton.flipX = _flipPlayer; /// what graphs gives me

And i need:
_skeletonMec.skeleton.FlipX = _flipPlayer; ///F - uppercase

Thats why i cant use graph with SPINE. Because in SPINE should be FlipX

 

Sorry for late answer.

I just tested the Spline, it look like the `FlipX` is Obsolete:

You can use the `ScaleX` instead or if you want to use the FlipX then enable the `Show Obsolete Item` in uNode preferences:

The new update required Unity 2019.4 or newer.

Upgrade Note:
Make a backup and follow the upgrade instruction on : http://docs.maxygames.com/unode/manual/installing.html#updating-unode
If you're not follow the upgrade instruction, your graph will be broken.

 

Cool!
What version of Unity is recommended to work with the latest version of uNode?
(Because the required minimum version and the recommended version are two different issues.)

 

The new update required Unity 2019.4 or newer.

 

If stability is your focus, because uNode's interface is built off the Unity editor, 2019LTS is also the recommended version as it's the most stable Unity version. I've seen various issues in 2020/2021 because of Unity that users have had to hope for Unity to resolve, live with them, or downgrade.

 

Ok, it's logical what you write. Thank you. However - last year I was working in the configuration: uNode + Unity 2020.3.x and I had no major problems. Unity 2020 has some features that the 2019 version does not have - so I'll try to keep working with Unity 2020.

 

I recommend to use LTS version of Unity.
uNode is tested on all LTS version and i had not found major problem with it.

 

Hi, I just change bolt to uNode on my project.
How to Trigger custom event?
And I found the website document is out of date.
Lack of new node descriptions（etc:Event hook）

 

many of us from other visual script assets and we started with them. so we dont understand- do like in c#/ we need pictures) or gifs/on unode documentation no about events too)

btw maybe you can make event in bolt and convert to unode and watch how it parse it/ but im not sure this works

 

You can try this if you are able to upgrade your project to from Bolt to unity visual scripting,
Add following namespace to your script: Unity.VisualScripting
Just click in any empty space in Unode Editor and will show up in inspect windows on the right where you can add it (search does not work for me just scroll down and you will find it)



next you can use CustomEvent.Trigger node to tigger custom event.

 

didnt know how create events too
/ i saved and parsed script (nice option) from unity docs
https://docs.unity3d.com/ScriptReference/Events.UnityEvent.html

and its kinda like on screen/ dont know yet will be it cast to all objects in scene or script owner/ and how transfer values.

 

you can also use Component.BroadcastMessage do the some thing.just dont forget to create method name it as methodName.

 

one more option for event. 1screen object sender (runtime). object reciever (class component)
2screen ivoke function with data

with scripts work like get component ( get script on object) and invoke function in it 3 screen

screen4 if send from class component to class component it need first store gameobject in variable or find in script and i add maxygames. unode to see unodespawner component in add node menu

screen5 as i understand it works only with c# class - create monobehavior . then variable UnityEvent -compile to script . and when put script on object it will be options to choose object and invoke its functions

dont know will be it problems with build then. cos this all works so easy. no listeners delegates lambdas etc

 

i dont recommende this way,becasue the methods you are using is not meant to used like that, also always to try Unity API in first place if you can then go to other option.
One note,the GameObject.sendMsg does not work with Runtime Graphs.currentlly you can use it with C# Graphs only.

 

and how to use them properly? hm people dont recommend use send message

https://answers.unity.com/questions/982211/is-sendmessage-or-getcomponent-faster.html#:~:text=SendMessage is absurdly much slower,and calls the method directly.
SendMessage is absurdly much slower.

SendMessage has to go through every script, look for a method with the same name using string comparrison (slower), and call it. The GetComponent finds the script through type comparrison (faster), and calls the method directly.

never use SendMessage, it's horrible.

 

i am assuming, there will initial overhead only then for second time will not be that much.Is much like coroutines.Also you dont need consider performance unlese you have performance issue.
Regards how to use it properly, is a good practice is always to try use game engine API, and if does not work for try use .NET next you you maybe use 3d party API get job done.

In Unity Visual Scripting there are ‘Application Variables’ is there something similar in uNode?

I tries in version 2.1.3 I tried creating C# Script -> Class and I added ‘Score’ variable with with modifiers set to Public and Static.

I need to see the value for ‘Score’ after score was increase in game. How do I see the ‘Score’ variable the inspector?

 

Yes, it's the Singleton Graph with Persistence on ( It's also show variable value during playmode ):


But you can also use C# Class Graph and use static variable modifier ( need to compile before use ).

Accessing Singleton variable or C# Graph static variable is like accessing c# static variable.

 

you need compile it to script and then add it to object in inspector and you will see them

thats workflow for c#class you edit in unode and then compile to script

second screen - for 2 other modes runtime and graph :variables seen in editor too

 

hello, does uNode support ref return?

example code:

Code (CSharp):

1.         ref int GetRef(ref int i)
2.         {
3.             return ref i;
4.         }
5.  
6.         void Foo()
7.         {
8.             int a = 1;
9.             ref var result = ref GetRef(ref a);
10.         }

 

Sorry, uNode doesn't currently support ref return.
