c# - Unity 2D: WaitForSeconds() delay isn't working

Question

I'm trying to add a delay between player.healthDisplay.color = Color.green; and player.healthDisplay.color = Color.white; but at the moment yield return new WaitForSeconds(5); and player.healthDisplay.color = Color.white; aren't working.

Here's my code:

public void OnTriggerEnter2D(Collider2D other)
{
    if (other.CompareTag("Player"))
    {
        StartCoroutine(ColorChange());           
    }
}

IEnumerator ColorChange()
{
    player.health++;
    Instantiate(effect, transform.position, Quaternion.identity);
    Destroy(gameObject);
    player.healthDisplay.color = Color.green;
    //until here code the code is working

    yield return new WaitForSeconds(5);
                         
    player.healthDisplay.color = Color.white;
}

Answer 1

You are destroying the gameobject which has this script on it.

Destroy(gameObject);
// color changing code, etc..

Once the gameobject has been destroyed this script will no longer run.

What you can do instead (if you need this gameobject to be destroyed immediately) is add a script to health display that will handle the color change.
