Hello! I cant slove 1 error with 3d text. I see many YouTube video and for uploaders of video its works, but with my projects its dont work... Here my Update script. i just call that script from another to update text value .

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class PointTracker : MonoBehaviour {
 
      GameObject PointNum;
      Text TextNum;
 
      int CurrentPoints = 0;
 
     // Use this for initialization
     void Start () {
         PointNum = GameObject.Find("PointNum");
         TextNum = PointNum.GetComponent<Text>();
         UpdatePoints(CurrentPoints);
     }
     
     // Update is called once per frame
     void Update () {
     
     }
 
     public void UpdatePoints(int addNum)
     {
         CurrentPoints = CurrentPoints + addNum;
         TextNum.text = "" + CurrentPoints;
     }
 }

 TextNum.text = "" + CurrentPoints;

WOOOOOHO! I slove it, just change

 TextNum = PointNum.GetComponent<Text>();

to

 TextNum = PointNum.GetComponent<TextMesh>();

and change declare TextNum from Text to TextMesh and all work!
