GUIText doesn't work anymore, since enter of "Canvas".

Most of the time you were able to change your text of GUIText, by saying
"public GUIText mytexttochange;", I tried to do it, but whenever I add this line, and then I want to drag text into the slot, it denies it, it also denies canvas, such thing as UIText doesn't exist according to Monodevelop and I don't know what to do. The code I have is, but it says that "Text" doesn't exist in current context.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using UnityEditor.UI;
4.  
5. public class PointCounting : MonoBehaviour {
6.     public Text PointGUI;
7.     public int Points = 0;
8.  
9.     void Start() {
10.         PointGUI.text = "Points: " + Points;
11.     }
12.  
13.     void Update() {
14.  
15.     }
16. }

According to this:

It should kind of work.

 

The namespace is UnityEngine.UI, not UnityEditor.UI.

Code (csharp):

1. using UnityEngine.UI;

UnityEditor.UI exists, but you want UnityEngine.UI
