I'm using a Canvas and a text component (See attached file)

How do i though script make it change to like. Time.deltaTime?

 

You can do something like this, place this on the text component:

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3. using System.Collections;
4.  
5. public class TextTest : MonoBehaviour {
6.     void Update () {
7.         GetComponent<Text>().text = Time.deltaTime.ToString();
8.     }
9. }
10.
