Error cs1003 syntax error expected unity

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class NewBehaviourScript : MonoBehaviour
{
    public string firstName;
    public string lastName;
    public int birthYear;
    // Start is called before the first frame update
    void Start()
    {
        print("Your first name is : " + firstName + "and your last name is " + lastName);
        print("Your initials are: " firstName[0] + lastName[0]);
        print("The lenght of your full name is " (firstName + lastName).Length);
        int Age = 2018 - birthYear;
        print("Your age is :" + Age.ToString );
        int dayAlive = Age * 365;
        print("You lived: " dayAlive.ToString "days");
    }

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

This is a code I made following a tutorial (few simple problems to get an understanding of the basics)

And I keep getting these errors:

Severity Code Description Project File Line Suppression State

Can someone please help me??

aboba11235, ты скинул совсем не рабочий код. Это лишь одна из ошибок, которая ждала бы тебя в будущем.
Его даже исправить нельзя. Его нужно просто переделать. Я просто укажу на ошибки.

1) Почитай документацию к GUI.Label: https://docs.unity3d.com/Scrip… Label.html
2)

public не нужен, если ты ищешь объект внутри этого же кода (строка 14)
3)

Такого метода нет. Есть OnCollisionEnter и его параметр должен быть типа Collision.
4)

Отработка нажатий должна вызываться каждый кадр, а метод OnCollisionEnter вызывается единожды при касании. (Скорее всего стоит заменить на OnCollisionStay)
5)

Ты назвал переменную так же, как и класс? Опрометчивое решение. Будут ошибки. Пофантазируй на эту тему.
6)

А теперь главная ошибка. И она вытекает из пункта 5. Компилятор думает, что ты пытаешься туда засунуть класс Score, а классы со строкой не совещаются, какое горе. Тебе нужна переменная Score в скрипте Score? Тогда обращайся к классу Score и его полю Score (согласно пункту 5 её стоит переименовать).

Если вдруг ещё останутся вопросы, задавай.

When uploading my game to Unity Distribution Portal (UDP), I kept on receiving this message about sandbox testing:

It seems your game was never tested in the UDP Sandbox environment, as no UDP Initialization call was found on the UDP back-end.
Launch your APK in the UDP Sandbox environment to ensure it initializes properly. You must complete this step to release your game.

Now, I initially thought that Unity sandbox testing was enabled as soon as you installed the UDP plugins, but I have read that you need to make a script like this for the testing procedures to pass:

using UnityEngine;
using UnityEngine.UDP;

public class InitListener : IInitListener
{  
     public void Initialize()
     {
          StoreService.Initialize(IInitListener listener);
     }
     public void OnInitialized(UserInfo userInfo)
     {
          Debug.Log("Initialization succeeded"); 
     }
     public void OnInitializeFailed(string message)
     {
          Debug.Log("Initialization failed: " + message);
     }
}

However, I kept on encountering a syntax error that said

InitListener.cs(9,49): error CS1003: Syntax error, ‘,’ expected

…Even though there’s no need for a «,».

Typppi also suggested calling from another script to refer to this one, which I have made:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UDP;

public Script listener;
public class Initializer : MonoBehaviour
{
    void Start()
    {
        StoreService.Initialize(IInitListener listener);
    }
}

Yet it still returns the same syntax error. Even then, what am I supposed to do with this initialization script? Where do I assign it?

Thank you for reading.

I have just started unity and am very puzzled by the error that appears:
AssetsScriptsBird.cs(11,28): error CS1003: Syntax error, ',' expected
The AssetsScriptsBird.cs(11, 18) if my file name.

I have looked else where but all of the answers have not been relevant are the error seems really general. I’d imagen it is very obvious but I have only just started. Thanks

Sorry for not including the full code… but here it is now:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Bird : MonoBehaviour
{

    [SerializeField] float _launchForce = 500;

    Vector2 startPosition;
    Rigidbody2D rigidbody2D:
    SpriteRenderer spriteRenderer;

    void Awake()
    {
        rigidbody2D = GetComponent<Rigidbody2D>();
        spriteRenderer = GetComponent<SpriteRenderer>();
    }

    // Start is called before the first frame update
    void Start()
    {
        startPosition = rigidbody2D().position;
        rigidbody2D().isKinematic = true;
    }

    void OnMouseDown()
    {
        spriteRenderer().color = new Color(1, 0, 0, 225);
    }

    void OnMouseUp()
    {
        spriteRenderer().color = new Color(1, 1, 1, 225);
        Vector2 currentPosition = rigidbody2D().position;
        Vector2 direction = startPosition - currentPosition;
        direction.Normalize();

        rigidbody2D().isKinematic = false;
        rigidbody2D().AddForce(direction * _launchForce);

    }
    void OnMouseDrag()
    {
        
        Vector3 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        transform.position = new Vector3(mousePosition.x, mousePosition.y, transform.position.z);
    }

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

}
