How to setup UnityObjectPooler in your Unity project?

Step 1).

Add IEnemy.cs, and ObjectPool.cs to your project.

---

Step 2).

This step is completely optional but it might be useful to create a base class for your enemy, like I did with PoolBehaviour script which implements MonoBehaviour and IEnemy interface. Look at this script for reference.

---

Step 3).

Let your Enemy monobehaviour class implement IEnemy interface OR your base class:

public class DroidEnemy : MonoBehaviour, IEnemy {

}

OR

public class DroidEnemy : PoolBehaviour {

}

---

Step 3).

If you went with the interface solely you must implement all required methods from the interface. For references look at the PoolBehaviour script. It is a base class that implements IEnemy and MonoBehaviour. It has all requirements implemented from the interface.

---

Step 4).

Open up IEnemy.cs and configure your EnemyTypes in the enum.

---

Step 5).

(If you went with the base class way) Override GetEnemyType method on your enemy class like so:

public override EnemyType GetEnemyType() { return EnemyType.YourCustomType; }

(otherwise implement the GetEnemyType method from the interface and return your type)

---

Step 6).

Use the ObjectPool's static methods

ObjectPool can be accessed at all times.

ObjectPool.Clear(); // Clears the pool (should be used on scene reload or new scene load because its static)

ObjectPool.Add(enemy); // Takes IEnemy type so any class that inherits IEnemy class can be passed

ObjectPool.Get(EnemyType.YourCustomType); // EnemyType will be your custom enemy types

ObjectPool.Get<ConcreteType>(EnemyType.YourCustomType); // This will cast your IEnemy to the concrete type passed

ObjectPool.GetUniqueId(); // Get's a unique id

ObjectPool.GetAmountInPool(EnemyType.YourCustomType); // Retrieves an int based on how many of this type are in the pool

For some examples on using the ObjectPool class look at the ObjectPoolTests.cs There I have a scenario for all calls.
