Delegates? Basically, UnityEvents. But Cooler | Unity C# Basics Part 5
Learn about what delegates are, when to use them, compare their functionality with a UnityEvent, and when you should use a UnityEvent over a delegate! In this video we'll be covering all of that and implementing our first delegate so we can raise an event when our AutoDestroyText is destroyed!
If you've been using Unity for a while, or are just getting started with Unity and decided it's time for you to start learning how to write code - this is the video series you need to start your programming journey!

Update your singleton MonoBehaviour to raise events when it spawns an object and when that object is destroyed! For the simplest implementation you can just do a Debug.Log but think about the signature of the event so you can apply it to your game!
