Changing Toggle UI's value (Checked or Unchecked)

Questions & Answers
1

I can’t seem to find a way wherein we can change the value of the Toggle UI.

Setting it to checked or unchecked. I wonder if it’s really impossible or I’m just missing something.

Why I need it?:
I’m developing a 3D Game where there are ImageEffects such as Bloom, Motion Blur, and Antialiasing.
And I have a pause menu with settings that toggles those ImageEffects to turn it on or off.

Somehow, I wanted it to be saved in PlayerPrefs so once an ImageEffect is off, it will stay off once you open the game again.

I think it’s something like

toggle.isOn = true

You use .isOn to set the value. E.G

using UnityEngine;
using UnityEngine.UI;

public class HelpSomeone : MonoBehaviour
{
    GameObject inGameToggle;

    private void Start()
    {
        inGameToggle = GameObject.Find("Toggle Name");
    }

    //Use buttons linked to this
    public void ChangeValueToTrue()
    {
        inGameToggle.GetComponent<Toggle>().isOn = true;
    }

    //Use buttons linked to this
    public void ChangeValueToFalse()
    {
        inGameToggle.GetComponent<Toggle>().isOn = false;
    }

}

yes, it is possible.
use bool var for every image-effects so every time when open the game set-get player pref for image-effects.

You can use isOn attribute to check whether the toggle button is checked or not. Also, set the isOn attribute to toggle the button.

 using UnityEngine;
 using UnityEngine.UI;
 
 public class ToggleDemo : MonoBehaviour
 {
     [SerializeField]
     private Toggle toggle;
 
     private void Start()
     {
         Debug.Log("Toggle button status: " + toggle.isOn);
     }
 
     public void ChangeToggleTrue()
     {
        toggle.isOn = true;
	    Debug.Log("Toggle button status: " + toggle.isOn);
     }
 
     public void ChangeToggleFalse()
     {
        toggle.isOn = false;
	    Debug.Log("Toggle button status: " + toggle.isOn);
     }
 }

There is a place where you should not change the .isOn value. That place is in a function which is triggered by a user clicking on the toggle. Do not monkey around the associated .isOn value THERE. There’s a race condition. Instead put a check in Update to see if you should change isOn for a toggle. If you try to change the isOn of a toggle in a function caused by a user click it may or may not work
