Problem with type Text: null reference

[EmilioMN]

Hi, I have this code:

using UnityEngine;
using UnityEngine.UI;
using System.Collections;

    public class Puntos: MonoBehaviour {
    
        public Text textScore;
        public int score = 0;
    
       public void Start(){
             textScore.text = "Score: " + score; 
        }
    
        public void AddPoints(int add){
           score += add;
           textScore.text = "Score: " + score;
        }
    }

Then, in another class I have:

private Puntos p = new Puntos();
p.AddPoints(5);

Why does Unity shows me a NullReference error when I call “AddPoints” method (it breaks when I try to set the new Text…) ?
I can’t understand how it fails there, if when I initialize the

private Puntos p = new Puntos();

I have the same piece of code.

Thanks in advance!

When you are creating a new Puntos object named p, you are not referencing any Text object to textScore.

Your code should be something like this;

public void Start()
{
    textScore = GameObject.Find("textScoreinCanvas").GetComponent<Text>();
    textScore.text = "Score: " + score.ToString(); 
}
