The modifier 'private' is not valid for this item

Hello!
I followed a YouTube tutorial on how to make a 2D game in Unity by Kyle Suchar.

But when I run the game it says:
Assets\Grounded.cs(40,5): error CS0106: The modifier 'private' is not valid for this item
All compiler errors have to be fixed before you can enter playmode!
UnityEditor.SceneView:ShowCompileErrorNotification()

My c#:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Grounded : MonoBehaviour
{
GameObject Player;
// Start is called before the first frame update
void Start()
{
Player = gameObject.transform.parent.gameObject;
}

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

private void OnCollisionEnter2D(Collision2D collision)
{
if (collision.collider.tag == "Ground")
{
Player.GetComponent<Move2D>().isGrounded = true;
}
}





private void OnCollisionExit2D(Collision2D collision)
{
if (collision.collider.tag == "Ground")
{
Player.GetComponent<Move2D>().isGrounded = false;
}
}
}}

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Grounded : MonoBehaviour
6. {
7.     GameObject Player;
8.     // Start is called before the first frame update
9.     void Start()
10.     {
11.         Player = gameObject.transform.parent.gameObject;
12.     }
13.  
14.     // Update is called once per frame
15.     void Update()
16.     {
17.  
18.     private void OnCollisionEnter2D(Collision2D collision)
19.     {
20.         if (collision.collider.tag == "Ground")
21.         {
22.             Player.GetComponent<Move2D>().isGrounded = true;
23.         }
24.     }
25.  
26.  
27.  
28.  
29.  
30.     private void OnCollisionExit2D(Collision2D collision)
31.     {
32.         if (collision.collider.tag == "Ground")
33.         {
34.             Player.GetComponent<Move2D>().isGrounded = false;
35.         }
36.     }
37. }}

And I wonder what I did wrong.

I'm using Unity version 2019.3.6

I would be very grateful if you could help me ;D

My Move2D:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Move2D : MonoBehaviour
6.  
7. {
8.     public bool isGrounded = false;
9.     public float moveSpeed = 5f;
10.     // Start is called before the first frame update
11.     void Start()
12.     {
13.        
14.     }
15.  
16.     // Update is called once per frame
17.     void Update()
18.     {
19.         Vector3 movement = new Vector3(Input.GetAxis("Horizontal"), 0f, 0f);
20.         transform.position += movement * Time.deltaTime * moveSpeed;
21.     }
22.  
23.     void Jump()
24.     {
25.         if (Input.GetButtonDown("Jump"))
26.         {
27.             gameObject.GetComponent<Rigidbody2D>().AddForce(new Vector2(0f, 5f), ForceMode2D.Impulse);
28.         }
29.     }
30. }
31.  
32.  

and my Grounded:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Grounded : MonoBehaviour
6. {
7.     GameObject Player;
8.     // Start is called before the first frame update
9.     void Start()
10.     {
11.         Player = gameObject.transform.parent.gameObject;
12.     }
13.  
14.     // Update is called once per frame
15.     void Update()
16.     {
17.  
18.     private void OnCollisionEnter2D(Collision2D collision)
19.     {
20.         if (collision.collider.tag == "Ground")
21.         {
22.             Player.GetComponent<Move2D>().isGrounded = true;
23.         }
24.     }
25.  
26.  
27.  
28.  
29.  
30.     private void OnCollisionExit2D(Collision2D collision)
31.     {
32.         if (collision.collider.tag == "Ground")
33.         {
34.             Player.GetComponent<Move2D>().isGrounded = false;
35.         }
36.     }
37. }}
38.  

 

It's just a typo, you are missing a close bracket "}" around line 17 on the Update() method.
Make sure your brackets match up, it looks like you have an extra at the bottom of the file as well.

 

Thank you very much Zombiegorilla ;D

 

Just made the same mistake as u do XD

 

I have a similar problem but cannot find a typo

 

Can I have help or be redirected to another post

 

This is my code:

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

public class UIController : MonoBehaviour
{

public static UIController instance;

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

public Slider healthSlider;

public Image fadeScreen;

public float fadeSpeed = 2f;
private bool fadingToBlack, fadingFromBlack;

// Start is called before the first frame update
void Start()
{

}

// Update is called once per frame
void Update()
{
if(fadingToBlack)
{
fadeScreen.color = new Color(fadeScreen.color.r, fadeScreen.color.g, fadeScreen.color.b, Mathf.MoveTowards(fadeScreen.color.a, 1f, fadeSpeed * Time.deltaTime));

if(fadeScreen.color.a == 1f)
{
fadingToBlack = false;
}
} else if(fadingFromBlack)
{
fadeScreen.color = new Color(fadeScreen.color.r, fadeScreen.color.g, fadeScreen.color.b, Mathf.MoveTowards(fadeScreen.color.a, 0f, fadeSpeed * Time.deltaTime));

if(fadeScreen.color.a == 0f)
{
fadingFromBlack = false;
}
}

public void UpdateHealth(int currentHealth, int maxHealth)
{
healthSlider.maxValue = maxHealth;
healthSlider.value = currentHealth;
}

public void StartFadeToBlack()
{
fadingToBlack = true;
fadingFromBlack = false;
}

public void StartFadeFromBlack()
{
fadingToBlack = false;
fadingFromBlack = true;
}
}
}

 

The public modifier was working at one point but when I went to reload my game it called me out on the last three voids.
