Question I need help integrating UI Toolkit and Visual Script

Good morning, I apologize for the inconvenience, and I apologize in advance for my English. My native language is Spanish. I need help integrating UI Toolkit with Visual Script. I'm developing a demo app, and I think it would be easier for me to do it visually rather than through code since I'm still learning C#. I already have the interface done in UI Builder, and it works perfectly with C#, but I would like to transfer the little I've done to Visual Script. Please help, I really appreciate your time. I have already searched a lot on the internet, but I couldn't find enough information to make it work. I have attached a screenshot of what I have so far. At the moment, I need help making the test button print some text in the console when clicked. Once I can connect that, I think I can understand how it works and move forward with the rest.

Thank you very much again for your help.

 

Hi,
you would need to use the result from the Query extension node (which is a VisualElement) and register the button events on it. And you would have to hook a trigger into the Q node to make it actually execute.


The key part would be to register the callbacks on the button. To do that you could implement a custom c# Event<T> node:

Code (csharp):

1. registerCallbacks(VisualElement ve) // That's the result from the Q Node
2. {
3.    var button = ve as Button;
4.    if (button != null)
5.    {
6.        button.RegisterCallback<ClickEvent>(handleEvent);
7.    }
8. }
9.  
10. protected void handleEvent(ClickEvent evt)
11. {
12.    // Do your stuff
13. }

I have written an asset that automates and streamlines the process, though it's not released yet. However, the manual is already online: https://kamgam.com/unity/UIToolkitVisualScriptingManual.pdf
If you look into it you can see how this could be done (I did it with custom nodes).

 

Thank you very much, it worked !

 

Any update on this tool? I would love to purchase it!
