Testing the Object Pool implementation

To test our implementation of the Object Pool in your own instance of Unity, you need to carry out the following steps:

1. Create a new empty Unity scene.
2. Copy all the scripts we just reviewed and save them in your project.
3. Add an empty GameObject to the scene.
4. Attach the following client script to your empty GameObject:

using UnityEngine;

namespace Chapter.ObjectPool
{
    public class ClientObjectPool : MonoBehaviour
    {
        private DroneObjectPool _pool;

        void Start()
        {
            _pool = gameObject.AddComponent<DroneObjectPool>();
        }

        void OnGUI()
        {
            if (GUILayout.Button("Spawn Drones"))
                _pool.Spawn();
        }
    }
}

Once you start your scene, you should see a graphical user interface (GUI) button named Spawn Drones in the top-left corner, as we can see in the following screenshot:
