I am making a 2D platform game. I use the following script to respawn a player when he dies. I want to delay the level being reloaded by about 2 seconds, so the death sound can play. It is respawning too fast. I'm a newbie. any help will be appreciated.

You can use a coroutine to accomplish this:

 public class Restarter : MonoBehaviour
 {
     private void OnTriggerEnter2D(Collider2D other)
     {
         if (other.tag == "Player")
             audio.Play ();
         coinController.screwCount = 0;
         StartCoroutine (DelayedLoad ());    
     }
 
     private IEnumerator DelayedLoad()
     {
         yield return new WaitForSeconds (2.0f);
         Application.LoadLevel(Application.loadedLevelName);
     }
 }
