Feedback NullReferenceException: Object reference not set to an instance of an object ScoreUI.UpdateScore (Sy

I get the error in the title.

I'm very new to coding, and my issues are the following:

-When the player collides with a "Food" It does not disappear after eating it, but the player still gets bigger
-The Score on the screen does not increase when eating foods

PlayerController:

using UnityEngine;
public class PlayerController : MonoBehaviour
{
public float moveSpeed = 5.0f;
public float maxSize = 5.0f;
public int maxScore = 100;
public float playerScaleFactor = 0.1f;
private Vector2 movement;
private float currentSize = 0.7f;
private int currentScore = 0;
private Vector2 targetPosition;
public ScoreUI scoreUI;
private void Start()
{
scoreUI = GameObject.Find("Canvas").GetComponentInChildren<ScoreUI>();
targetPosition = transform.position;
}
private void Update()
{
HandleInput();
targetPosition += movement * moveSpeed * Time.deltaTime;
transform.position = Vector2.Lerp(transform.position, targetPosition, 0.1f);
}
private void HandleInput()
{
float moveHorizontal = Input.GetAxis("Horizontal");
float moveVertical = Input.GetAxis("Vertical");
movement = new Vector2(moveHorizontal, moveVertical).normalized;
if (movement.magnitude > 0)
{
float angle = Mathf.Atan2(movement.y, movement.x) * Mathf.Rad2Deg + 270f;
transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);
SpriteRenderer spriteRenderer = GetComponentInChildren<SpriteRenderer>();
if (spriteRenderer != null)
{
float spriteAngle = angle;
if (spriteRenderer.transform.localScale.x < 0)
{
spriteAngle += 180;
}
spriteRenderer.transform.rotation = Quaternion.AngleAxis(spriteAngle, Vector3.forward);
}
}
}
public void IncreaseSize(float sizeIncrease)
{
currentSize += sizeIncrease;
if (currentSize > maxSize)
{
currentSize = maxSize;
}
transform.localScale = new Vector3(currentSize, currentSize, currentSize) * playerScaleFactor;
}
public void UpdateScore(int scoreIncrease)
{
currentScore += scoreIncrease;
if (currentScore > maxScore)
{
currentScore = maxScore;
}
scoreUI.UpdateScore(currentScore);
}
}


ScoreUI:

using UnityEngine;
using UnityEngine.UI;
public class ScoreUI : MonoBehaviour
{
public Text scoreText;
private void Start()
{
UpdateScore(0);
}
public void UpdateScore(int score)
{
scoreText.text = "Score: " + score;
}
}

FoodController:


using UnityEngine;
public class FoodController : MonoBehaviour
{
public int scoreValue = 10;
public int minPoints = 1;
public int maxPoints = 1;
public float minSize = 0.1f;
public float maxSize = 0.3f;
public float moveSpeed = 2.0f;
private int pointValue;
private float foodSize;
private Rigidbody2D rb2d;
private void Start()
{
bool hasRigidbody2D = gameObject.GetComponent<Rigidbody2D>() != null;
// Assign a random size and point value to the food object
pointValue = Random.Range(minPoints, maxPoints + 1);
foodSize = Random.Range(minSize, maxSize);
transform.localScale = new Vector3(foodSize, foodSize, foodSize);
// Get a reference to the rigidbody component
rb2d = GetComponent<Rigidbody2D>();
// Apply a random initial velocity to the food object
Vector2 randomVelocity = Random.insideUnitCircle.normalized * moveSpeed;
rb2d.velocity = randomVelocity;
}
private void OnTriggerEnter2D(Collider2D other)
{
if (other.CompareTag("Player"))
{
PlayerController playerController = other.GetComponent<PlayerController>();
if (playerController != null)
{
playerController.IncreaseSize(foodSize);
playerController.UpdateScore(pointValue);
}
else
{
Debug.LogError("PlayerController component not found on Player object!");
}
Destroy(gameObject); // destroy this game object
}
}
}




I want the rocket to eat the stars, adding to the ui score and make the stars disappear after colliding.

 

None of the above matters. The answer is always the same:

How to fix a NullReferenceException error

https://forum.unity.com/threads/how-to-fix-a-nullreferenceexception-error.1230297/

Three steps to success:
- Identify what is null <-- any other action taken before this step is WASTED TIME
- Identify why it is null
- Fix that

In the future, if you post a code snippet, ALWAYS USE CODE TAGS:
