Button in Highlighted state instead of Normal when going back from Disabled

Hello there !

Ok let's say I have 2 panels :
- I press a button from panel 1
- it displays panel 2 and set panel 1 to not interactable (canvas group)
- I press the back button in panel 2
- it displays panel 1 but the first pressed button is in "Highlight" state instead of "Normal"

I use the On Click () feature in Button inspector to make these actions.

Is that a bug or I miss something maybe.. ?

Regards,
P.

 

Ok looks like it's a bug : https://forum.unity.com/threads/clicking-a-button-leaves-it-in-mouseover-state.285167/

 

It's been like this for years, there are many thread with people trying to fix it and there's even a bug report that's been marked as "fixed" (even though it's not - at least not in 2017.3.1f1). I contacted the support about it and according to them:

"...this is by design and it doesn't seem like the behavior will be changed any time soon..."

What you can do about it:
- Change the color back to "Normal" yourself
- Set the button's "Navigation" to "None". This also means that you can't use your keyboard or controller to navigate to or from the button and you won't get a proper object from the EvenSystem (possibly even "GameObject.Find"). Also: "None" won't fix it for touchscreens, I had to...
- Set the highlighted color to the normal color

It sucks, I know. It's probably best to contact the support and hope that they'll end up fixing it if enough users complain.

 

Hey thanks for the answer SimRuJ !

Based of answers here : click
I wrote this code, it works with joystick and mouse;

(bug : if you click on the mouse and move the joystick at the same time, joystick navigation is not working anymore.)

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3. using UnityEngine.EventSystems;
4.  
5. // Class that prevents button from being in "Highlighted" state after being in "Disabled" state
6. public class ButtonBugFix : MonoBehaviour, IPointerExitHandler
7. {
8.     // mouse event
9.     public void OnPointerExit(PointerEventData eventData)
10.     {
11.         Fix();
12.     }
13.  
14.     // joystick and keyboard event
15.     void Update()
16.     {
17.         if (Input.GetButtonDown("Submit"))
18.         {
19.             Fix();
20.         }
21.     }
22.  
23.     // fix button state
24.     public void Fix()
25.     {
26.         GetComponent<Button>().enabled = false;
27.         GetComponent<Button>().enabled = true;
28.         GetComponent<Animator>().SetTrigger("Normal");
29.     }
30. }
31.  
32.  

edit : add this on your buttons

Hope it helps !

 

I posted in the thread you linked (very last post) but completely forgot about it because I've been using "None". There's a shorter way:

This way the button should get unselected, even with the navigation set to "Automatic". I haven't tested it with a touchscreen yet though.

 

Your second option worked for me, thanks
