How do I play popup intro opening animation?

Unity Engine
1

I have a pause popup panel in a different scene that gets loaded on top of the game scene through LoadSceneMode.Additive. I have made custom animations but whenever I try to play them I keep getting null reference error but whenever I test it in the scene with the popup panel it works.

Also if I made the time scale to 0 when the pause popup opens, how can I still keep playing the popup intro animation?

Heres what I have. I just took the area the code where I’m referencing the animation.

  void Start()
    {
        _anim = GameObject.FindGameObjectWithTag("Pause").GetComponent<Animator>();
    }

    IEnumerator Intro()
    {
        _anim.SetBool("Intro",true);
        yield return new WaitForSeconds(clip.length);
        _anim.SetBool("Intro",false);
        yield return null;
    }

Are you sure your tag is the same as the object? Also what is the point in making it a corentine if it only runs once when you pause there should be no problem making it a normal void function.

Yea its tagged. The problem is the object the script is referencing is inside a different scene. How can I access the gameobject in a different scene. I’m using coroutine because for outro animation I think I need it because i want the animation to finish and then close the popup. For intro it doens’t really matter your right.

I do not think its possible to access a gameobject in another scene from the current open scene. You could try something like instantiate the gameobject in your new scene before the animation runs.

Ok thanks. i’ll give that a try.

Thanks for the help mumbot. This is what I came up with and it works.

using UnityEngine;
using System.Collections;
using UnityEngine.SceneManagement;

public class ButtonManagerPause : ButtonManager
{
    public Animator anim;

    void Start ()
    {
        //make it not be affected by Time.Timescale = 0
        anim.updateMode = AnimatorUpdateMode.UnscaledTime;
        anim.SetBool("Intro", true);
    }
       
    public new void UnloadScene(string scene)
    {
        StartCoroutine("Outro", scene);
    }

    IEnumerator Outro(string scene)
    {
        Time.timeScale = 1f;
        AudioListener.volume = 1;
        _IsPauseActive = false;
        anim.SetBool("Outro", true);
        //get the animation length of the Outro animation
        yield return new WaitForSeconds(anim.GetCurrentAnimatorStateInfo(0).length);
        SceneManager.UnloadScene(scene);
        yield return null;
    }
}
