How to get if UI button is currently highlighted?

Unity Engine

Hi,

Trying to figure out a simple way to know if a UI button is currently highlighted or not, this is for using a gamepad or keyboard, so I can’t use OnPointerEnter or OnMouseOver methods or anything that exclusively uses a mouse.

I’m not proficient in C#.

I’ve been googling around but nothing seems to work so far -

This one only works once the button is selected, not highlighted.

This seems to be the closest thing to what I want, but I can’t seem to make this work, I get the error “No overload method for “IsHighlighted” takes 1 arguments” and I have no idea how to fix it.

Thank you!

What’s your code look like?

did you guys figure it out? I also want to check if it’s highlighted. I’m using unity 2021.2, but my error says The name ‘isHighlighted’ does not exist in the current context.

using UnityEngine;
using UnityEngine.Events;
using UnityEngine.EventSystems;
using UnityEngine.UI;

public class IsSelected : Selectable
{
    BaseEventData BaseEvent;
    public GameObject dot;

    void Update()
    {
        if (isHighlighted(BaseEvent) == true)
        {
            dot.SetActive(true);
        }
        else
        {
            dot.SetActive(false);
        }
    }
}

is my code.

C# is a case sensitive language. It is IsHighlighted.

now I have the error No overload for method ‘IsHighlighted’ takes 1 arguments

IsHighlighted has no parameters. Are you familiar with documentation and C# language by any means?

I have a small amount of experience with C#

nevermind I used chatgpt cause I wanted to make this work quickly and got it working.
If anyone has this problem imma leave my script.

using UnityEngine;
using UnityEngine.EventSystems;
using UnityEngine.UI;

public class IsSelected : MonoBehaviour, ISelectHandler, IDeselectHandler
{
    private bool isHighlighted = false;
    public GameObject dot;

    public void OnSelect(BaseEventData eventData)
    {
        isHighlighted = true;
        dot.SetActive(true);
        Debug.Log("Button Highlighted");
    }

    public void OnDeselect(BaseEventData eventData)
    {
        isHighlighted = false;
        dot.SetActive(false);
        Debug.Log("Button Unhighlighted");
    }

    // You can use isHighlighted in other parts of your script as needed.
}

Umm just to clear this up, you would use IsHighlighted like a bool, all you had to do was put the selectabke Before it and take the BaseEvent out of the parenthesis for it to return correctly. I dont recommend anyone use chatgpt ever. It’s only worthwhile to write boilerplate if u akready know what ur doing, otherwise you wont learn anything.

100% agreed. I’m a proud brain user.

By the way, what about this solution?

using System;
using UnityEngine.EventSystems;
using UnityEngine.UI;

namespace SomethingSomething.UI
{
    public class BaseButton : Button
    {
        public static event Action<BaseButton> OnSelectButton = delegate { };

        public override void OnSelect(BaseEventData eventData)
        {
            base.OnSelect(eventData);
            OnSelectButton(this);
        }
    }
}
