Changing Toggle UI's value (Checked or Unchecked)

Question

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.

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;
     }
 
 }

I know that this is an old question but I still wanted to address one more issue. When setting the isOn on the toggle, the value was correct but the pressed color that I specified was not showing. I had to call the Select() on the Toggle component to make sure that next to being 'isOn' it also showed as a selected toggle color.

I think it's something like

 toggle.isOn = true

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.

$$anonymous$$ay I know what's the syntax for changing the Toggle UI?

Fore example, I have a Toggle variable: $$anonymous$$otionBlurToggle.

Is there something like: $$anonymous$$otionBlurtoggle.checked = true;

I am not exactly sure what you are asking for, but I hope this answers your question:

 // This will show you the state of your toggle in the console
 bool toggleState;
 $$anonymous$$otionBlurtoggle.isOn = toggleState;
 Debug.Log(toggleState);
 
 
 // This will toggle your Button on and off
 $$anonymous$$otionBlurtoggle.isOn = !$$anonymous$$otionBlurtoggle.isOn
 // Simply put: Turn my Toggle-State into what it is not
 // So if on, turn it off. If off, turn it on

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
