How to display a variable value on screen?

I have installed Unity 4.6 and I have read the docs but I haven't found any explanation about how to display a variable value (a counter, for example) on screen with the new UI.
Sorry if it is a silly question but the part about Text (label) only refers to the string being displayed. I assume the variables are referenced by code. Is this correct?
Thanks

 

First and foremost you need a Text object on the canvas where you want to print the text.

Then you can reference to this text by code.
Let's say you want to display a score counter. There are a few things to remember.
The most important one is if you want to access UI by script youo need to include "using UnityEngine.UI;" otherwise you can't acces any of the new UI functions by code.
Then you can create a Text object which you can reference to by Text.text = "yourTextHere";

So it might look something like this:

Code (CSharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4. using UnityEngine.UI;  // IMPORTANT!!!!!!!!
5.  
6. public class ScoreCounter : MonoBehaviour {
7.  
8.     public Text scoreText;  // public if you want to drag your text object in there manually
9.     int scoreCounter;
10.  
11.     void Start () {
12.         scoreText = GetComponent<Text>();  // if you want to reference it by code - tag it if you have several texts
13.     }
14.  
15.     void Update () {
16.         scoreText.text = scoreCounter.ToString();  // make it a string to output to the Text object
17.     }
18. }
19.  

(edit) sorry - found a typo on my code. it's scoreText.text, of course.

 

this ones the typo
