What is the best method to queue multiple directions?

Hi everyone

I'm working on something of an endless runner and I found a tutorial on Queues. Following the tutorial I managed to create a row of generated objects that are different.

I am curious what would be the best method of adding more generated rows?

• Create a new Queue for every row I wish to have present and updating with the character's movement

• There's a way of adding multiple directions/re-positions in one Queue - if there is how can it be achieved?

Currently, the code for one row looks like this:

 function Start () 
 {
     objectQueueTop = new Queue.<Transform>(numberObjectsUp);
     for(var x = 0; x < numberObjectsUp; x++)
     {
         objectQueueTop.Enqueue((Transform).Instantiate(prefab));
     }
     
     nextPositionUp = startPositionUp;
     
     for(var y = 0; y < numberObjectsUp; y++)
     {
         Recycle();
     }
 }
 
 function Update () 
 {
     if(objectQueueTop.Peek().localPosition.y + recycleOffset < RunnerScript.distanceTraveledY)
     {
         Recycle();
     }
 }
 
 private function Recycle()
 {
     var positionUp : Vector2 = nextPositionUp;
     positionUp.x += 0.5f;
     positionUp.y += 0.5f;
     
     var oUp : Transform = objectQueueTop.Dequeue();
     oUp.localPosition = positionUp;
     objectQueueTop.Enqueue(oUp);
     
     nextPositionUp += gapUp;
 }

Any help, tips and pointers will be greatly appreciated.

Thanks!
