The name does not exist in the current context (Unity 2D)

Unity Engine

I’m new to coding in Unity and I’ve found this code that I wanted to use for my game but it states that “The name ctrl does not exist in the current context”. How can I fix this?

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

public class PickUp : MonoBehaviour
{
    private bool _isPickedUp = false;

    void Update()
    {
        if (Input.GetKeyDown(KeyCode.LeftControl))
        {
            ctrl = true;
        }
        else if (Input.GetKeyUp(KeyCode.LeftControl))
        {
            ctrl = false;

            if (_isPickedUp)
            {
                transform.SetParent(null);
                _isPickedUp = false;
            }
        }
    }

    private void OnCollisionStay2D(Collision2D collision)
    {
        if (ctrl && !_isPickedUp && collision.gameObject.tag == "Player")
        {
            transform.SetParent(collision.transform, true);
            _isPickedUp = true;
        }
    }
}

New to C# also :slight_smile:

private bool _isPickedUp = false;
private bool ctrl = false;
