Stop Player character from moving inside wall (Raycast Teleport to new Position)

Hi there, I am making a top down game where the player moves by shooting a projectile. Using Raycast I have am able to move the character but now the player moves over the walls and does inside them. How can i stop this.

 void Update()
 {
     if(Input.GetButtonDown("Fire1"))
     {
         Shoot();
     }
     
     
 }
 void Shoot()
 {
    GameObject projectile = Instantiate(_projectilePrefab,_firepoint.position,_firepoint.rotation);
    Rigidbody2D rb = projectile.GetComponent<Rigidbody2D>();
    rb.AddForce(_firepoint.right *_projectileForce,ForceMode2D.Impulse);
    RaycastHit2D hit = Physics2D.Raycast(_firepoint.position,_firepoint.right,100,_wall);
    if(hit.collider!=null)
    {
    if(hit.collider.CompareTag("Wall"))
    {
        Debug.Log($"Hit");
        _rb.MovePosition(hit.point);
    }
    }
 }
