Creating an object adapter class

An object adapter is almost exactly the same as a class adapter, but with the added wrapper around a concrete adaptee reference instead of subclassing – in our case, a private TeleportController object instead of inheriting from TeleportController. To see this in action, create a new C# script in the Scripts folder, name it TeleportObjectAdapter, and update its code to match the following snippet, which uses the wrapped adaptee object to execute the underlying adaptee logic:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
// 1
public class TeleportObjectAdapter : MonoBehaviour, IController
{
    public float hoverHeight = 3;
    private bool _isLevitating;
    // 2
    private TeleportController _adaptee;
    // 3
    void Start()
    {
        _adaptee = this.GetComponent<TeleportController>();
    }
    void Update()
    {
        _isLevitating = Input.GetKey(KeyCode.Space);
    }
    public void Move...
