Identifier expected unity ошибка

As a beginner in programming, I am currently enrolled in a C# course, but I am encountering an error with the code as it generates the
compiler error
error message.

I have gone through the description of
Compiler Error
(link provided), but I am still struggling to understand it. Can you help me identify my mistake?

Check out the Microsoft Developer Network (MSDN) website for detailed information on the topic. The specific link is http://msdn.microsoft.com/en-us/library/b839hwk4.aspx.

Here is my source code:

using System;
public class InputMethodDemoTwo
{
   public static void Main()
   {
      int first, second;
      InputMethod(out first, out second); 
      Console.WriteLine("After InputMethod first is {0}", first);
      Console.WriteLine("and second is {0}", second);
   }
   public static void InputMethod(out first, out second) 
   // The error is citing the line above this note.
   {
      one = DataEntry("first"); 
      two = DataEntry("second");
   }
      public static void DataEntry(out int one, out int two)
      {
         string s1, s2;
         Console.Write("Enter first integer ");
         s1 = Console.ReadLine();
         Console.Write("Enter second integer ");
         s2 = Console.ReadLine();
         one = Convert.ToInt32(s1);
         two = Convert.ToInt32(s2);
      }
}

As per the guidelines, I should possess a function b (InputData) that extracts statements from function c (DataEntry). The given directions state:

In Figure 6-24, the InputMethodDemo program includes redundant code within
inputmethod
(). This code prompts the user and retrieves
integer values
. To address this issue, modify the program so that the InputMethod() method calls a separate method to perform the necessary actions. By doing so, the new and improved InputMethod() will only require two statements.

one = DataEntry(«first»);

two = DataEntry(«second»);

Save the recently developed software as InputMethodDemo2.cs.

The program being discussed, known as InputMethodDemo, only utilizes the InputMethod instead of both methods.

The mentioned material is «An Introduction to
Object-Oriented Programming
,» which is a part of the book «Microsoft® Visual C#® 2008, 3rd edition» by Joyce Farrell.

Assistance or guidance would be highly valued.

The following are the tasks that are expected of you.

using System;
public class InputMethodDemoTwo
{
    public static void Main()
    {
        int first, second;
        InputMethod(out first, out second);
        Console.WriteLine("After InputMethod first is {0}", first);
        Console.WriteLine("and second is {0}", second);
        Console.ReadLine();
    }
    public static void InputMethod(out int first, out int second)
    //Data type was missing here
    {
        first = DataEntry("first");
        second = DataEntry("second");
    }
    public static int DataEntry(string method)
    //Parameter to DataEntry should be string
    {
        int result = 0;
        if (method.Equals("first"))
        {
            Console.Write("Enter first integer ");
            Int32.TryParse(Console.ReadLine(), out result);
        }
        else if (method.Equals("second"))
        {
            Console.Write("Enter second integer ");
            Int32.TryParse(Console.ReadLine(), out result);
        }
        return result;
    }
}

Change

public static void InputMethod(out first, out second)
{
  one = DataEntry("first");     
  two = DataEntry("second");
}

to

public static void InputMethod(out DataEntry first, out DataEntry second)
{
  first = DataEntry("first"); 
  second = DataEntry("second");
}

The argument types have not been specified and they are labeled as «first» and «second» instead of «one» and «two».

This is the code I use to attach my player to
moving platform
using the label «s».

I encountered the CS1001 error with
Identifier expected
and unfortunately, I couldn’t find any helpful resources on YouTube.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerAttach : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        
    }
    // Update is called once per frame
    void Update()
    {
        function OnTriggerEnter(other.Collider){
            if (other.gameObject.tag == "player")
            {
                transform.parent = other.transform;
            }
        }
        function OnTriggerExit(other.Collider){
            if (other.gameObject.tag == "player")
            {
                transform.parent = null;
            }
        }
    }
}

You possess

unityscript

which is an outdated and lengthy code that cannot function with

c#

.

Avoid nesting MonoBehaviour messages under

Update

, as doing so will prevent the messaging system from finding them and result in them not being called at all.

Your class should look like

public class PlayerAttach : MonoBehaviour
{
    private void OnTriggerEnter(Collider other)
    {
        // Rather use CompareTag instead of ==
        // the latter fails silently in case of s typo making your debugging live only harder
        if (!other.CompareTag("player")) return;
        
        transform.parent = other.transform;
    }
    private void OnTriggerExit(Collider other)
    {
        if (!other.CompareTag("player")) return;
        
        transform.parent = null;
    }
}

Additionally, it’s worth asking how the player object can exit the collider if it is made a parent, as this would cause the object to move in tandem with the player whenever they
object moves
it.

For a long time, I’ve been attempting to resolve this issue to enable the viewing of the game in play mode. The script is responsible for the enemy AI, which pursues the player.

The transformation error occurs at coordinates (90,32) during the player’s attack by
enemys vision
.

The problematic code involves the transformation of LookAt(player).

Any help would be much appreciated.

Identifier Expected
in Unity

If your code contains
incorrect, meaning
syntax, it indicates that there is an error in the code written by you.

transform LookAt(player);

should be

transform.LookAt(player);

The whitespace (


) present in the code is not functional and does not contribute to the transformation process. To access the properties and methods of a GameObject’s (

transform

) transform, use a dot (

.

). By using this dot (

.

), you can access the transform’s (

LookAt

) method.

There will be a error:

Transform the following:

invoke(nameof(ResetAttack), timeBetweenAttacks);

to:

Invoke(nameof(ResetAttack), timeBetweenAttacks);


As a beginner in c# coding, I attempted to display and propel the ball towards the user, however, encountering the CS1001 error has left me perplexed. It would be greatly appreciated if someone could provide assistance.

 public GameObject("ball");
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
    float y = 50;
    float dX = y * 0.8f;
    // y = (vNotY ^ 2) / 2g
    float vNotY = y * 2 * Physics.gravity.y;
    vNotY = Mathf.Sqrt(vNotY);
    // t = 2 * v0y / g
    float time = 2 * vNotY / Physics.gravity.y;
    // v = d / t
    float vX = dX / time;
    Vector3 force = new Vector3(vX, vNotY, 0);
    ball.rigidbody.AddForce(force);
}

}

public GameObject("ball");

change to

public GameObject ball;

variable declaration

accessibility class variablename ;
