I’m creating a queue, and I can’t develop function logic for the previous object to assume the new position released - C#

Question

I’m using unity3D, so my queue consists of Gameobjects, are 7 Gameobjects lined up next to each other and my purpose with this code is that every click of the user - "Simplemove function" - the objects move forward one position, except the last one, this must take the last position.

In Unity it is possible to associate the Gameobjects by the interface, so consider the two full arrays already at the beginning.

I would like help to understand and develop the logic in "Simplemove function" make this drive. Thank you

using UnityEngine;
using System.Collections;

public class StairsController : MonoBehaviour {

    public GameObject[] degrau;
    Vector3[] positionArray = new Vector3[7];

    private int i = 6;
    private int a = 6;

    // Use this for initialization
    void Start () {
        positionArray [i-6] = degrau[a-6].transform.position; 
        Debug.Log (positionArray [i-6]);

        positionArray [i-5] = degrau[a-5].transform.position;
        Debug.Log (positionArray [i-5]);

        positionArray [i-4] = degrau[a-4].transform.position;
        Debug.Log (positionArray [i-4]);

        positionArray [i-3] = degrau[a-3].transform.position;
        Debug.Log (positionArray [i-3]);

        positionArray [i-2] = degrau[a-2].transform.position;
        Debug.Log (positionArray [i-2]);

        positionArray [i-1] = degrau[a-1].transform.position;
        Debug.Log (positionArray [i-1]);

        positionArray [i] = degrau[a].transform.position;
        Debug.Log (positionArray [i]);
    }

    public void SimpleMov (){
        degrau [a].transform.position = positionArray [i - 1];
    }
}

Great tip: only use array for one-size structures that do not need modification, for variable sizes and other strings use "List" is much easier and you will have great processing savings.

You will need to

using System.Collections.Generic;

To start

List<GameObject> degrau= new List<GameObject>();

To add elements

degrau.Add(**teu degrau aqui**);

To remove the element has several options, but this should be the most suitable.

degrau.RemoveAt(int index)

and

degrau.Clear()

to clean up

I don’t have a list-specific video, but I use it in this video here https://www.youtube.com/watch?v=5U3d9iwHm2I
