Problem with yield/IEnumerator

Questions & Answers

Hi guys…i am working on a 2D shooting game in which enemy gets destroyed after getting hit by a bullet and then reappears after 2 sec at some random position on x-axis.

my code is :

using UnityEngine;
using System.Collections;

public class collision : MonoBehaviour {

IEnumerator OnCollisionEnter (Collision objectCollided)
{
	if (objectCollided.gameObject.name == "enemy")
	{
		Destroy(this.gameObject); // to destroy bullet
		objectCollided.gameObject.renderer.enabled = false;
		yield return new WaitForSeconds(2);
		
		GameObject.Find("enemy").transform.position = new  
                                          Vector3(Random.Range(9.0f,23.0f),3.5f,0); 

		objectCollided.gameObject.renderer.enabled = true;
	}
}

}

The problem is that enemy disappears but does not reappear anywhere. If i use void instead of IEnumerator and delete yield statement, then it works fine but then there is no time delay.
Please advice me how to do this.

That can’t work since you destroy the object that the script is on. So none of the code after Destroy will run.
