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

public class Movement : MonoBehaviour
{

public float speed;
public float jump;

private float movement;
private Rigidbody2D rb;
private bool isGrounded;
private bool canJump;

public Transform groundCheck;
public float groundCheckRadius;

public LayerMask whatIsGround;

// Start is called before the first frame update
void Start()
{
    rb = GetComponent<Rigidbody2D>(); 
}

// Update is called once per frame
void Update()
{
    CheckSurroundings();
    movement = Input.GetAxis("Horizontal");

    rb.velocity = new Vector2(movement * speed, rb.velocity.y);

    if (Input.GetButtonDown("Jump"))
    {
        if (canJump)
        {
            rb.AddForce(new Vector2(rb.velocity.x, jump));
        }
    }
}

private void FixedUpdate()
{
    CheckSurroundings();
}

private void CheckSurroundings()
{
    isGrounded = Physics2D.OverlapCircle(groundCheck.position, groundCheckRadius, whatIsGround); 
}

private void OnDrawGizmos()
{
    Gizmos.DrawWireSphere(groundCheck.position, groundCheckRadius);  
}

Hİ, i have got another algorithm for jump so i think you can try it

     private Rigidbody2D playerRB;    
    public float jumpSpeed;
    void Start()
        {
    
            playerRB = GetComponent<Rigidbody2D>();
            footCollider = GetComponent<BoxCollider2D>();
            
        }
    
    void FixedUpdate(){
             if (Input.GetKey(KeyCode.Space))
                {
                    Jump();
                }
    }
        void Jump()
        {
                //multi jump skill disabled.
                if (!footCollider.IsTouchingLayers(LayerMask.GetMask("Ground"))) return;
    
                playerRB.AddForce(new Vector2(0f, jumpSpeed));
                PlayerAnimator.SetInteger("State", 3);
            
            
        }

So i think you can try it

Hello,

it seems to me that canJump is never true in your code.
Edit line 7:

private bool canJump = true;

Edit lines 30 to 35:

{
   if (canJump) {
     float timeBetweenTwoJumps = 2f;
     canJump = false;
     rb.AddForce (new Vector2 (rb.velocity.x, jump));
     while (timeBetweenTwoJumps> 0) {
       timeBetweenTwoJumps -= Time.delta.Time;
     }
     canJump = true;
}

Good luck (and sorry for any mistakes in English).

There’s no errors and I still can’t jump!!
here’s my code!

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

public class Movement : MonoBehaviour
{
    private bool canJump = true;
    public float speed;
    public float jump;
    private float timeBetweenJumps = 0;
    private float movement;
    private Rigidbody2D rb;
    private bool isGrounded;

    public Transform groundCheck;
    public float groundCheckRadius;


    public LayerMask whatIsGround;

    // Start is called before the first frame update
    void Start()
    {
        rb = GetComponent<Rigidbody2D>(); 
    }

    // Update is called once per frame
   
            void Update()
            {
                CheckSurroundings();
                movement = Input.GetAxis("Horizontal");
                rb.velocity = new Vector2(movement * speed, rb.velocity.y);

                //Add a short cooldown between jumps
                if (timeBetweenJumps > 0)
                {
                    timeBetweenJumps -= Time.deltaTime;
                }

                //If we have waited for the cooldown and we are on the ground, then we can jump again
                if ((timeBetweenJumps <= 0) && isGrounded) canJump = true;
                else canJump = false; //If we are not grounded, we cannot jump

                if (Input.GetButtonDown("Jump") && canJump)
                {
                    canJump = false;
                    timeBetweenJumps = 0.2f;
                    rb.AddForce(new Vector2(rb.velocity.x, jump));
                }
            }
        
    

    private void FixedUpdate()
    {
        CheckSurroundings();
    }

    private void CheckSurroundings()
    {
        isGrounded = Physics2D.OverlapCircle(groundCheck.position, groundCheckRadius, whatIsGround);
    }

    private void OnDrawGizmos()
    {
        Gizmos.DrawWireSphere(groundCheck.position, groundCheckRadius);
    }
}
