Unity 显示“错误 CS1022：类型或命名空间定义，或预期的文件结尾”

Question

I am making a cross board game using Unity based on a tutorial. This problem occurs when I add a jump animation. All my code is from that tutorial and no changes have been made except for one value.

I know which line of code is wrong but I don't know why and I don't know how to fix it.

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

public class Playermovement : MonoBehaviour
{
  private Rigidbody2D rb;
    public float jumpAmount = 1;

    bool isGrounded;
    public Transform groundCheck;
    public LayerMask groundlayer;
    public Animator anim;
    public float overlap = 0.5f;
   

    void Start()
    {

        rb = gameObject.GetComponent<Rigidbody2D>();
    }

    private void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            if (isGrounded)
            {
                Jump();
            }
        }
    }

    private void FixedUpdate()
    {
        isGrounded = Physics2D.OverlapCircle(groundCheck.position, overlap, groundlayer);
    }

    void Jump()
    {
        rb.AddForce(Vector2.up *5* jumpAmount, ForceMode2D.Impulse);
    }

    if(isGrounded)
        {
            anim.SetBool("Jump",false);
        }
        else
        {
            anim.SetBool("Jump", true);
        }
}

Does anyone know what's wrong with this, please? Thank you in advance to those who answered!

Assets\Script\Playermovement.cs(52,1): error CS1022: Type or namespace definition, or end-of-file expected

This is the error message I received. I know it tells me the error occurred on the first character of line 52 (which is the last line), but other than that I don't know anything because there is only one curly bracket on that line.

Answer 1

The problem is with if (isGrounded) statement. The if/else statement needs to be in a method/function , and can't work without being in one.
