Observer pattern and delegates

Question

Please, someone, guide with a daily life example of how many attributes observer pattern has as I think

1. I need a subscriber which is simple contains methods.

2. Observer:
In which I will subscribe method.

3. Provider: This is unknown to me but it is in ms documentation.

Moreover, I wanted to reduce the dependency of my game scripts but I am not sure how to start working with this pattern.

Start from basic and just give push than I will work on finding the complex usability.

Thanks in advance 😊

Answer 1

This recent course by Unity might be exactly what you're looking for:

https://learn.unity.com/project/c-scripting-in-unity-the-observer-pattern

Although I haven't personally reviewed it yet, the summary does seem to cover what you're looking for.

Since it is a recent course, I would hope it mentions the new Entity Components System (ECS) and DOTS architecture.

You may want to take a look at this as well:

These references will do a better job than what anyone can try to explain in a short answer post.

Hope this helps.

Answer 2

Observe able and observers are introduced in the observer pattern in which we use subscription and in subscription to reduce the dependency.
For example

In my case, I use it as a simple delegate that subscribes to the methods at the game start, by which I am easy to handle dependency. Of game states. I am still reading so, please don't mind if I was wrong. Good luck 👍

Also mention if it can be a mess in expanding my project as I am already with refactoring again and again 😩
