Trying to reference a float, but it wont work?

Questions & Answers
1

I have an object, called ‘Point’, that is set to ‘is trigger’, and has a script called ‘GetPoint’ that will cause it to destroy itself and change a float, ‘points’, by +1 when the player comes in contact with it. I am trying to display the points in a ui - text script called ‘Score’. It seems to work, but after the player touches the object and the score is displayed in the console (which is how I set it while trying to get it to work) the following error message appears.

NullReferenceException: Object reference not set to an instance of an object
Score.Update () (at Assets/Score.cs:18)

GetPoint script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class GetPoint : MonoBehaviour {

public GameObject pickupEffect;
public float points = 0f;

void OnTriggerEnter (Collider other)
{
    if (other.CompareTag("Player"))
    {
        Pickup();
    }
}

void Pickup()
{
    //Instantiate(pickupEffect, transform.position, transform.rotation); ignore this

    points += 1f;
    Debug.Log(points);
    Destroy(gameObject);
}

}

Score script:

using UnityEngine;

public class Score : MonoBehaviour
{

GameObject Point;

// Update is called once per frame
void Update()
{
    GameObject Point = GameObject.Find("Point");
    GetPoint GetPoint = Point.GetComponent<GetPoint>();
    Debug.Log(GetPoint.points);
}

}

Please help!

it adds score,. and then in this line it destroys the point object

     Destroy(gameObject);

I think you better to change your script to something like this.

    public class Score : MonoBehaviour {

        public int score;
    public Text scoreText;

      public  void AddScore(int a)
 {
    score+=a;
      scoreText.text=score.tToString ();
 }

you should not check this stuff in update function.so in this case only if you pick points,they will add score ,not 50 times per frame (if you use update)

and Points Script

   public GameObject pickupEffect;
    public int points = 0f;
   void OnTriggerEnter (Collider other)
    {
 if (other.CompareTag("Player"))
 {
     Pickup();
 }
    }
    void Pickup()
    {
 //Instantiate(pickupEffect, transform.position, transform.rotation); ignore this
 points = 1;
 Debug.Log(points);
FindObjectOfType<Score> ().AddScore(points);
 Destroy(gameObject);

}
