Removing and Re-adding an object

Unity Engine
1

When I try this it removes the object but it doesn’t come back after 1 second?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Flicker : MonoBehaviour {

    void Start()
    {
        StartCoroutine(Flash());
    }

    IEnumerator Flash()
    {
        while (true)
        {
            yield return new WaitForSeconds(1f);
            Destroy(this.gameObject);
        }
    }
}

The object gets destroyed so it no longers exists in the scene. Once it is destroyed, the coroutine is no longer executed either. I’m guessing you want to show/hide the object. You don’t want to do this on the object you want to show/hide as it will stop calling the Update method or running a coroutine. You will likely be better off enabling/disabling the renderer on the object or running the method from another object.

Even if the coroutine didn’t stop… what about that code would “bring the object back”? You would need an Instantiate call somewhere.
