Blink a mesh renderer 4 times-CodePudding

I am trying to blink my gameObject's mesh renderer 4 times with a delay of 0.25 seconds. The mesh renderer gets disabled in the beginning but never re-enables and never blinks. I thought the best way would be to use a for loop.

    MeshRenderer mr;

    void Start () {
        mr = this.gameObject.GetComponent<MeshRenderer> ();
        StartCoroutine (Blink ());
    }

IEnumerator BlinkLid () {
       for (int i = 0; i < 4; i  ) {
        mr.enabled = false;
        yield return new WaitForSeconds (0.25f);
        mr.enabled = true;
       }
    }

You also need to wait before the next iteration!

IEnumerator BlinkLid () 
{
   for (int i = 0; i < 4; i  ) 
   {
        mr.enabled = false;
        yield return new WaitForSeconds (0.25f); // or 0.125f if it shall take 0.25 in total
        mr.enabled = true;
        yield return new WaitForSeconds (0.25f); // or 0.125f if it shall take 0.25 in total
   }
}

otherwise you wait to set it to enabled = true but immeditely go to the next iteration where again you set it enabled = false ;)
