title: How to change text in Unity Text
body: <p>I'm trying to change text in <code>My_Text</code> but it doesn't work.
  I'm using <code>UnityEngine.UI.</code></p>
  
  <pre><code>using System.Collections;
  using System.Collections.Generic;
  using UnityEngine;
  using UnityEngine.UI;
  
  public class notbugdText : MonoBehaviour {
  
      public Text My_Text;
      // Use this for initialization
      void Start () {
          My_Text.text = "Hello world!";
      }
  
      // Update is called once per frame
      void Update () {
  
      }
  }
  </code></pre>
  
  <p>I've got error message: <code>Assets/scripts/notbugdText.cs(11,11): error CS1061: Type 'Text' does not contain a definition for 'text' and no extension method 'text' of type 'Text' could be found. Are you missing an assembly reference</code></p>
  
  <p>I'm using MonoDevelop-Unity to program in C#</p>
