Displaying the whole list in a single Text

Question

I'm a beginner to Unity, and want to make one sheet of input history, which is expected to show as (1, 2, 1, 2, 3,....) endlessly. But I can only pick one of numbers from the list, stating by mylist[1] in order. Is there any way I can state the whole list, and display as a Text?

 GameObject counter;

 public List<int> brain = new List<int>();

 // Use this for initialization
 void Start () {
     this.counter = GameObject.Find("Counter");

 }
 
 // Update is called once per frame
 void Update () {
     if (Input.GetKeyDown(KeyCode.Space))
     {
         brain.Add(1);
            }
     if (Input.GetKeyDown(KeyCode.RightArrow))
     {
         brain.Add(2);
     }
     if (Input.GetKeyDown(KeyCode.LeftArrow))
     {
         brain.Add(3);
     }
     counter.GetComponent<Text>().text = brain[0].ToString(); 

 }

Use this method to convert your list to string:

 private string ListToText(List<int> list)
 {
     string result = "";
     foreach(var listMember in list)
     {
         result += listMember.ToString() + "\n";
     }
     return result;
 }

Use it like this:

 counter.GetComponent<Text>().text = ListToText(brain);

Thank you so much! So, you could convert the list to string! This did not work on my script, so I'll study on "ListToText" because I will need it! :)

@daccithechopper I forgot to add semicolon after "\n". Should do the job now.

What you need is a for or a foreach loop.

Please see below a quick example of using a foreach loop

 GameObject counter;
     public List<int> brain = new List<int>();
     // Use this for initialization
     void Start()
     {
         this.counter = GameObject.Find("Counter");
     }
 
     // Update is called once per frame
     void Update()
     {
         if (Input.GetKeyDown(KeyCode.Space))
         {
             brain.Add(1);
         }
         if (Input.GetKeyDown(KeyCode.RightArrow))
         {
             brain.Add(2);
         }
         if (Input.GetKeyDown(KeyCode.LeftArrow))
         {
             brain.Add(3);
         }
 
         counter.GetComponent<Text>().text = ""; //Clear the text
         foreach (int item in brain) //Add each item to the text
             counter.GetComponent<Text>().text += item.ToString() + ", ";
     }

Thank you so much! The foreach loop worked just as I wanted. I was blindly just trying to get the whole list in the script, I should have tried to add to the text by myself, like this :)
