Trying to get "clickable.clicked" from button.

Hi, I'm trying to get my button clickable but I didn't manage to make it work. I tried the exemple of this thread https://forum.unity.com/threads/ui-builder-how-to-make-buttons-interactable.786701/ by uMathieu. What am I doing wrong ? Thank you for your help in advance.

Code (CSharp):

1. //Attatch this script to a Button GameObject
2. using System;
3. using System.IO;
4. using UnityEngine;
5. using UnityEngine.EventSystems;
6. using UnityEngine.UIElements;
7. using Button = UnityEngine.UIElements.Button;
8.  
9. public class buttonScript : MonoBehaviour
10. {
11.     public VisualTreeAsset visualTreeAsset;
12.     public StyleSheet defautStyleSheet;
13.  
14.     public void Start()
15.     {
16.         var root = new VisualElement();
17.         visualTreeAsset.CloneTree(root);
18.         root.styleSheets.Add(defautStyleSheet);
19.  
20.         var button = root.Q<Button>();
21.         Debug.Log(button.name);
22.         Debug.Log(button.text);
23.         button.clickable.clicked += () => Debug.Log("Clicked!");
24.     }
25. }
26.  
27.  

 

Add the button to the root object and that should fix it.

Edit: Just realized You did that. have you trued ClickedWithEventInfo? Does that work for you?

 

Hi, firstly thank you for your answer. So I've just tried to do that with your advice

Code (CSharp):

1.  public void Start()
2.     {
3.         var root = new VisualElement();
4.         visualTreeAsset.CloneTree(root);
5.         root.styleSheets.Add(defautStyleSheet);
6.  
7.         button = root.Q<Button>();
8.         Debug.Log(button.name);
9.         Debug.Log(button.text);
10.         button.clickable.clickedWithEventInfo += (evt) => Debug.Log("clicked 2");
11.         button.clickable.clicked += () => Debug.Log("Clicked!");
12.  
13.     }

But this too didn't do anything. I've got the last version of UIElements Runtime 0.0.4 so I don't really understand what's going on.

 

Try add an EventSystem component to your scene.

 

I thank both of you a lot, it works now. I've added the visualTree that was created with the PanelRenderer. I was also lacking an EventSystem.

 

Hi martinusprim,

Could you post your solution or edit the previous post? I can't get it to work even though I used the visualTree from the PanelRenderer and added an EventSystem. I'm using 2019.14.18f1 btw.
