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;
    }
}

and its string

TextNum.text = "" + CurrentPoints;

Call that error:

NullReferenceException: Object reference not set to an instance of an object
PointTracker.UpdatePoints (Int32 addNum) (at Assets/Scripts/PointTracker.cs:27)

Please help me and say what i am doing wrong…
Thanks.

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!

I some people will need that slove in future.
