Hello. I have some issuses with update Text value of 3d text object.

For example: I create 3d text, qube and ball.
When i trow ball in qube and ball collides with qube i need update text of 3d text to “1”.
i trying many ways, but unity show 1 error.

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

TextNum.text = "" + CurrentPoints;

Was creating error

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

Please, help, what i doing wrong?

If it’s a 3D text then it’s not a “Text” but a “TextMesh”.

TextNum = PointNum.GetComponent();
