Jumpscare Need Help

Hello everyone. I am new to Unity and I need a hand with a script for a jumpscare. I have attempted it and put all the triggers etc. Here is my attempt that I try but all I get are errors

public GameObject jumpscareObject;

void Start () {

    jumpscareObject.SetActive(false);
}

void OnTriggerEnter (Collider player) {
    if(player.tag == "Player")
    {
        jumpscareObject.SetActive(true);
       
    yield return new WaitForSeconds(1.5f);
    Destroy(jumpscareObject);
    Destroy(gameObject);
}

}

Like @ShadyProductions said, you need to use a coroutine if you want to use the delay. I would reorganize what you have above like this:

public GameObject jumpscareObject;

void Start()
{
    jumpscareObject.SetActive(false);
}
void OnTriggerEnter(Collider player)
{
    if (player.tag == "Player")
    {
        StartCoroutine(DoTheSpook());
    }
}

IEnumerator DoTheSpook()
{
    jumpscareObject.SetActive(true);
    yield return new WaitForSeconds(1.5f);
    Destroy(jumpscareObject);
    Destroy(gameObject);
}

Hope that helps!

IEnumerator OnTriggerEnter (Collider player)
{
if(player.tag == “Player”)
{
jumpscareObject.SetActive(true);

         yield return new WaitForSeconds(1.5f);
         Destroy(jumpscareObject);
         Destroy(gameObject);

    }
}

OnTriggerEnter can be used as a coroutine just give it the proper return type.
