I have looked almost 10 different topics but nothing worked for me.

I have such code

updateScore.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class updateScoreText : MonoBehaviour
{
    Text scoreText;
    // Start is called before the first frame update
    void Start()
    {
        scoreText = GetComponent<Text>();
    }

    // Update is called once per frame
    void Update()
    {
        
    }
    public void scoreUpdate(int score)
    {
        scoreText.text = "Score: " + score;
    }
}

I want to call scoreUpdate method in another script

I tried

public updateScore addScoreText;
addScoreText = GameObject.Find(“Text”).GetComponent().scoreUpdate(points);

in another script

but it shows error error CS1061: ‘updateScore’ does not contain a definition for ‘scoreUpdate’ and no accessible extension method ‘scoreUpdate’ accepting a first argument of type ‘updateScore’ could be found (are you missing a using directive or an assembly reference?)

,This is my full error :

I have two different scripts

PlayerPoint.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class playerPoint : MonoBehaviour
{
    public int points = 0;
    float timers = 0.0f;
    public int seconds = 0;
    bool scoreUpdated = false;
    public updateScore addScoreText;
    // Start is called before the first frame update
    void Start()
    {
        InvokeRepeating("addPoint",5.0f,5.0f);
    }

    // Update is called once per frame
    void Update()
    {

    }
    void addPoint()
    {
        if (scoreUpdated == false)
        {
            points += 5;
            addScoreText.scoreUpdate(points);
        }
    }
}

updateScore.cs

  using System.Collections;  
  using System.Collections.Generic;
  using UnityEngine;
  using UnityEngine.UI;
  public class updateScoreText : MonoBehaviour
{
    Text scoreText;
    // Start is called before the first frame update
    void Start()
    {
        scoreText = GetComponent<Text>();
    }

    // Update is called once per frame
    void Update()
    {
        
    }
    public void scoreUpdate(int score)
    {
        scoreText.text = "Score: " + score;
    }
}

Please could someone help me why I get this error when I already have scoreUpdate method in updateScore.cs file?

Silly question.

Solved finally.

I had two reasons.

First one is the class name should be same as file name.

Second one is I didn’t include updateScore script file to Text Object.
