Bug Toggle compent's OnValueChanged event not working.

I have a Toggle. When the user presses it, I see "IsOn" checking on/off. But the events in OnValueChanged are not triggered.

Here's a demonstration of the toggle not working:

And here are the functions I'm calling from the OnValueChanged:

Code (CSharp):

1. using UnityEngine;
2.  
3. public class TestDebugOfToggle : MonoBehaviour
4. {
5.  
6.     public void IsThisWorking(bool value)
7.     {
8.         if (value)
9.         {
10.             print("Yes, it's working. Truth.");
11.         }
12.         else
13.         {
14.             print("Yes, it's still working, and we're false.");
15.         }
16.     }
17.  
18.     public void SaySomething()
19.     {
20.         print("Something");
21.     }
22. }

 

Sorry - I just realized, I'm not sure if should have used the Bug prefix in the thead title, or Help Wanted. There are threads with similar issues, but those are years and years old.
Am I missing something? Or is this a years-old Unity bug?

 

Hi there, just pinging back.
Does anyone have any ideas?

 

I've changed the handle of this thread's title to 'bug'.
Hoping for some support.

 

I got the same issue, fwiw. It works fine in build, or if I attach the debugger to the editor, but it does not work in play mode.

 

If I toggle the 'isInteractible' property on the toggle component, at runtime, then it starts to work properly. So there is clearly a unity bug.

I found a repro - it happens if your toggle is inside a scroll view. I filed a bug report.

 

Ok for anyone else who finds this - a workaround while we wait for Unity to fix the issue is to set your toggles/sliders to send events in Editor + Runtime. Toggling the isInteractible property in a script won't work.

 

Old one but just had the same issue and found what was going on:

Watch this:

When selecting the method in the OnValueChange field you should select the from the Dynamic Bool options.
