Text mesh pro not disabling by script

Unity Engine

Hello! I am having a problem with my game. I have a script ( that is listed below ) that is supposed to show a text for some time and then make it disappear. This script is being done through a game object with a trigger collider. This script is working fine with the first game object, but then it is not working for the next game instance where I’ve used it ( as seen in the video listed below ). May anybody tell me what’s wrong in this instance and help me to fix this? Thank you!

Script used for the first text trigger ( the attack text ):

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using TMPro;

public class CollisionText : MonoBehaviour
{
    public TextMeshProUGUI enemyWarning;
    public float duration = 4f;
    [SerializeField] private Animator anim;

    void Start()
    {
        enemyWarning.enabled = false;
    }


    void OnTriggerEnter2D(Collider2D other)
    {
        if (other.tag == "Player")
        {
            StartCoroutine ( showText(other) );
        }
    }

    IEnumerator showText(Collider2D player)
    {
        enemyWarning.enabled = true; // displays text
        attackDemonstration();
        yield return new WaitForSeconds(duration); // waits an amount of time x
        enemyWarning.enabled = false; // makes the text invisible
        Destroy(gameObject); // destroys the trigger after the x amount of time
    }

    void attackDemonstration()
    {
        for(int i=1; i<=3; i++)
        {
            anim.SetTrigger("Attack");
        }
    }
}

Script used for the second text trigger that doesn’t disappear ( the test text ):

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using TMPro;

public class test : MonoBehaviour
{
    public TextMeshProUGUI enemyWarning;
    public float duration = 4f;
    [SerializeField] private Animator anim;

    void Start()
    {
        enemyWarning.enabled = false;
    }


    void OnTriggerEnter2D(Collider2D other)
    {
        if (other.tag == "Player")
        {
            StartCoroutine(showText(other));
        }
    }

    IEnumerator showText(Collider2D player)
    {
        enemyWarning.enabled = true; // displays text
        yield return new WaitForSeconds(duration); // waits an amount of time x
        enemyWarning.enabled = false; // makes the text invisible
        Destroy(gameObject); // destroys the trigger after the x amount of time
    }
}

Add Debug.Log statements to determine where the issue is occurring. In your Debug.Log statements verify the value of “duration”, verify you’re not starting multiple of the same coroutine, verify the code after the yield is being executed.

In the hierarchy, verify the GameObject which contains the “test” component is not being destroyed by something else before the coroutine has completed.
