how should i arrange my code to fix error CS1022-CodePudding

i was using unity to learn 2d game development, and i just got started with coding and game develompment. i encountered the Error:CS1022 Type or namespace definition, or end-of-life expected here is the code i've written:

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

{public class Player : MonoBehaviour
public Rigidbody2D rb;
public int movespeed;
    // Start is called before the first frame update
    void Start() { 
     rb = GetComponent<Rigidbody2D>();
    }

    // Update is called once per frame
    void Update() {
        if (Input.GetKey(KeyCode.LeftArrow))
    {
        rb.velocity = new Vector2 (-movespeed, rb.velocity.y);
    }
        if (Input.GetKey(KeyCode.RightArrow))
    {
        rb.velocity = new Vector2 (movespeed, rb.velocity.y);
    }
    if (Input.GetKey(KeyCode.Space))
    {
        rb.velocity = new Vector2 (rb.velocity.x, 5);
    }
    
public Transform groundCheck;
public float groundCheckRadius;
public LayerMask whatIsGround;
public bool onGround;

     void FixedUpdate()
     {
        onGround = Physics2D.OverlapCircle(groundCheck.position,
        groundCheckRadius,whatIsGround);
     }
}
}

` i was trying to make a control for my game character's jumping ability so that it couldn't fly by jumping.

it says that the error is at the line (39,1). i can't figure out how to fix this error can anyone help and explain what i was doing wrong?

i didn't know what to do since i had followed exactly how the book i'm using to learn coding says, and i've tried rearanging the code but to no avail.

CodePudding user response：

As others have pointed out in the comments, there are several formatting errors in your code, such as an extra opening bracket { before the class declaration and a missing closing bracket } for the Update method.

If you're working with an IDE such as Visual Studio, there's formatting options built in (Edit > Advanced > Format Document) which will help you organise the bracket indentations; although they won't auto-resolve the errors
