Bool parameter won't change through script, animation wont play OnClick

Question

I'm doing an android 2d platformer. In the Animator everything is set up. On applicaton start does everything right but when I click on the button the bool parameter does not change so my animation won't play backwards. But when I tick the bool parameter in the animator the animation plays right as it should. No console errors. Here is my script.

I was using this tutorial and from it I just needed the first part (the "Start game" animation part). I followed every step. Probably I'm missing something.

using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using UnityEngine.UI;
using UnityEngine;

public class UIManager : MonoBehaviour
{
    public Animator optionsButton;

    public void OpenSettings()
    {
        optionsButton.SetBool("isHidden", false);
    }
}

My goal is to play the animation backward when the option button is pressed and I want to change the bool parameter through a script.

Is the OpenSettins() method being called? add a debug message to it to make sure it is being called when you click the button. I say this as you might not have asigned the buttons onClick method in the editor. — akaBase
I used Debug.Log(Button Clicked); but same happend; when I clicked the button the parameter wont change but the debug message is written in the console. I expected at least an error message but there is none. — Jozef Benko
check that the animator isn't null and that the spelling of the bool parameter is correct because there is nothing wrong with the code. — akaBase
Can you advice me how can I check the animator isn't null? Well we can agree on that because I looked for a sollution and cant find anything. It is so weird. As I looked on the internet and can be the problem that one of a states in the animator is a copy of the default state? Found some kind of legacy issue and root issues but non of them worked. I have a feeling that it will be a bug or something pretty simple. I vote for the second :D — Jozef Benko
You can use a normal animator == null to check if it is null or not. I am starting to think that you have the single clip in you Animator and it is running the animation when you start the game/scene and then finishes. If so you need to restart it using options.Play("nameofnanimation"), also look into CrossFade — akaBase

The problem was that the script was trying to change the bool on a canvas child element object. And there wasn't a bool. So I altered the existing script to get it. Worked perfectly.

public class UIManager : MonoBehaviour
{

    public Animator optionsButton;
    public bool hide;

  private void Start()
   {
       //to find the parent element - canvas - which has a bool
       optionsButton = GameObject.Find("MainMenu").GetComponent<Animator>();
   }

    public void OpenSettings()
    {
        hide = true;
        optionsButton.SetBool("AnimOut", hide);

        Debug.Log("I'm finaly working!");
    }

}
