Unity error cs0106 the modifier public is not valid for this item - Исправление ошибок и поиск оптимальных решений проблем

AssetsGameControl2D.cs(25,10): error CS0106: The modifier ‘public’ is not valid for this item

This error is happening why? Please anyone let me help it to figure out.

using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    
public class GameControl2D : MonoBehaviour
{
    public static GameControl2D instance;
    public GameObject gameOverText;
    public bool gameOver = false;

    void Awake ()
    {
        if (instance == null)
        {
            instance = this;
        }
        else if (instance != this)
        {
            Destroy (gameObject);
        }
    }

    void Update ()
    {
         public void BirdDied()
        {
            GameOverText.SetActive (true);
            gameOver = true;
        }
    }
   
}

You have a nested/local method BirdDied, that can’t have access modifiers. It’s accessible only from the method body of Update anyway. So this compiles:

void Update ()
{
    void BirdDied()
    {
        GameOverText.SetActive (true);
        gameOver = true;
    }
}

But since you don’t use it in your code, i doubt that it’s what you want.

public class Bird2D : MonoBehaviour

    private bool isDead = false;
    private Rigidbody2D rb2d;

    private Animator anim;

    // Start is called before the first frame update
    void Start()
    {
        rb2d = GetComponent<Rigidbody2D>();
        anim = GetComponent<Animator>();
    }

    // Update is called once per frame
    void Update()
    {
        if (isDead == false)
        {
            if (Input.GetMouseButtonDown(0))
            {
                rb2d.velocity = Vector2.zero;
                rb2d.AddForce(new Vector2(0, upForce));
                anim.SetTrigger("Flap");
            }
        }
    }
    void OnCollisionEnter2D()
    {
        isDead = true;
        anim.SetTrigger("Die");
        GameControl2D.Instance.BirdDied();
    }
}

This is the Bird2D.cs file i already remove public from birdDied method but the error is same

Вы запутались в местоположении закрывающей фигурной скобки у метода Start.

Во первых не зачем дублировать темы!!!
Во вторых код положено обрамлять тегами

Your code is excessively verbose, and this is likely to lead to unexpected behaviours when copy-pasting the same script with minor changes. You can take advantage of data structures and loop statements to manage your GameObject activation/deactivation, and make your logic more flexible and less error-prone.

Storing GameObjects

You can define your colour presets as an array rather than individual elements:

public GameObject[] Primary;

The Inspector will let you expand the entries and assign the GameObjects of interest:

The advantage of having your GOs stored in an array is that you can use indices to access them, e.g. Primary[3] is your fourth object in the array (array indices start at 0).

Activating GameObjects

Since you have the same number of elements and buttons, you can just enable the GO of interest when the corresponding button is pressed. This can be achieved by knowing the GO index and looping through all GOs:

public void ColorButton(int index)
{
    for (int i = 0; i < Primary.Length; i++)
    {
        Primary[i].SetActive(i == index);
    }
}

Here index is an arbitrary value you pass as an argument. The function loops through all objects and sets as active only the one whose position in the array is equal to the index (i == index returns true), while deactivating all others (i == index returns false).

Binding the UI to the activation logic

To make the above function work on button click, you can select a Button and add an entry to its On Click () event in the Inspector. Then, drag the GameObject that has got your colour management script. Finally, look for the function defined above:

The input field below the function name is the value of index you want to pass as an argument when the function is triggered. You can change this value with different values for other buttons.

Each button will invoke the function with a different index value, and the ColorButton() function will take care of activating/deactivating the corresponding GameObject you assigned.
