Create a Pause In A For Loop

Question

I am currently trying to create a pause in my for loop so that it wait's X seconds before looping again. The reason for this is I will being picking 20 blocks and sending a ball to hit those 20 blocks but I want a pause in between this since I am using the ball to hit every block and I want it to take some time to happen.

         int countUpTo = 5;
         float waitTime = 5;
         
         for (int i; i <= 19; i++) {
             numbers = GameObject.FindGameObjectsWithTag ("num");
             index = Random.Range (0, numbers.Length);
             pickedNumber = numbers [index];
             print ("number picked");
             print (pickedNumber.name);
             
             transform.position = new Vector3 (0, 0, 0);
             print ("numer postion");
             print (pickedNumber.transform.position);
             
             ball = GameObject.FindGameObjectWithTag ("ball");
             float step = speed * Time.deltaTime;
             target = pickedNumber.transform;
             ball.transform.position = Vector3.MoveTowards (pickedNumber.transform.position, target.position, step);
             print ("ball");
             print (ball.transform.position);
 
             //Pause here
             yield return new WaitForSeconds(waitTime);
 
             ball.transform.position = new Vector3 (-11.4, .3299, -20.63);
         }

Your code is ok, just make sure it's inside a coroutine and start that coroutine using StartCoroutine("CouroutineName");

 void Start(){
     StartCoroutine("MyCoroutine");
 }
 
 IEnumerator MyCoroutine(){
 
  int countUpTo = 5;
          float waitTime = 5;
          
          for (int i; i <= 19; i++) {
              numbers = GameObject.FindGameObjectsWithTag ("num");
              index = Random.Range (0, numbers.Length);
              pickedNumber = numbers [index];
              print ("number picked");
              print (pickedNumber.name);
              
              transform.position = new Vector3 (0, 0, 0);
              print ("numer postion");
              print (pickedNumber.transform.position);
              
              ball = GameObject.FindGameObjectWithTag ("ball");
              float step = speed * Time.deltaTime;
              target = pickedNumber.transform;
              ball.transform.position = Vector3.MoveTowards (pickedNumber.transform.position, target.position, step);
              print ("ball");
              print (ball.transform.position);
  
              //Pause here
              yield return new WaitForSeconds(waitTime);
  
              ball.transform.position = new Vector3 (-11.4, .3299, -20.63);
          }
 }
