Toggle and OnValueChanged with inverse dynamic value ?

Unity Engine
1

With a toggle we can use a unityEvent to call function with dynamic parameters, like if toggle is ON then otherThing.gameObject.setActive() is also ON.
Very usefull to save script use, but can it be inversed?
I would like : if toggle is ON, then other gameObject is OFF.

I think this is an elegant solution:
Attach this component to your Toggle gameobject and check out the Inspector:

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

public class InvertedToggleEvent : MonoBehaviour{

    //wont show in inspector
    //public    UnityEngine.Events.UnityEvent<bool> toggleEvent;
 
    //this will show in inspector
    [System.Serializable]
    public class UnityEventBool : UnityEngine.Events.UnityEvent<bool>{}
    public    UnityEventBool onValueChangedInverse;
 

    private void Start()
    {
        GetComponent<Toggle>().onValueChanged.AddListener( (on)=>{ onValueChangedInverse.Invoke(!on); } );
    }
}

How to do that without a script?

I believe nothing has changed since then, so you don’t.
