Error-The body of `ScriptEnemy.RespawnWaittime()' cannot be an iterator block because `void' is not an iterator interface type

using UnityEngine;
using System.Collections;

public class ScriptEnemy : MonoBehaviour {
	public int noofclicks=2;
	public float respawnwaittime=2;
	// Use this for initialization
	
	// Update is called once per frame
	void Update () {
		if(noofclicks <=0)
		{
		Vector3 position=new Vector3(Random.Range(-5.0F,5.0F),0,Random.Range(-5.0F,5.0F));
			RespawnWaittime();
		transform.position=position;
		noofclicks=2;
		}
	}
void RespawnWaittime()
	{
		renderer.enabled=false;
		yield return WaitForSeconds (respawnwaittime);
		renderer.enabled=true;
	}
}

So you are starting a coroutine from update but in c# you need to do it like this:

  • Define RespawnWaitTime as a function returning IEnumerator (yield makes it do that)

  • Start it by calling StartCoroutine

  • yield return new WaitForSeconds

      using UnityEngine;
  using System.Collections;

 public class ScriptEnemy : MonoBehaviour {
 public int noofclicks=2;
 public float respawnwaittime=2;
 // Use this for initialization
 
 // Update is called once per frame
 void Update () {
 	if(noofclicks <=0)
 	{
 	Vector3 position=new Vector3(Random.Range(-5.0F,5.0F),0,Random.Range(-5.0F,5.0F));
 		StartCoroutine(RespawnWaittime());
 	transform.position=position;
 	noofclicks=2;
 	}
 }
 IEnumerator RespawnWaittime()
 {
 	renderer.enabled=false;
 	yield return new WaitForSeconds (respawnwaittime);
 	renderer.enabled=true;
 }

    }
