How to use Delegates in Unity. Like a BOSS.



Delegates are a programming language feature that allows to invert the dependencies in the classes of your program. Delegates are also referred as Events or Callbacks. The idea behind them is exactly the same as a subscription magazine. Anyone can subscribe to the service and they will receive the update at the right time automatically. This is a super powerful way of designing the architecture of your game to achieve the next level in code quality.

If you enjoyed my previous article about how to use Lerp, this is the second of many simple tutorials to learn how to use the full potential of Unity following what I found out are the best practises. Follow this easy examples you will have projects that are not a nightmare to maintain after a couple of weeks of development. :)

If you started to program in Unity as your first serious programming job, it may be even possible that you don't know what delegates, callbacks or observers are. Don't be scared, we will talk about everything in detail. Anyway I recommend you to take a look at the official tutorials here and here if you haven't done it already and come back here to answer the rest of your questions. :D

One call at the right time is better that 60 calls a second until they pick up.
