🌟 If you liked this video, I recommend that you also watch another one in which I explain the Observer Pattern and how to use signals in Godot: kzfaq.info/get/bejne/q7R0qrmpxM7SdXU.html

Thank you for explaining this in a video, I was reading documentation and it just wasn't clicking and as soon as you demonstrated I was able to work it how I needed to. Very helpful!

i was confused at what a "Singleton pattern" was, turns out I was using it in godot for my Global variables

First time ever I've heard someone use Phonk as their background music in a tutorial, and I'm mega vibing with it

It's a great track. I am very grateful to all the musicians who make their music available without copyright ❤️‍🔥

I do this as well on my game. Also using Core as main scene and then instantiate and queue free levels is good too. Its similar as well for performance

Technically script classes are resources which are in effect singletons. The Script Resource itself only has 1 version of itself in the project period. So making a static instance of the scripts instance would store the instance in the resource at runtime. Now why you would want to do this... to rage against the machine?

Thanks for the video David. I'm new developing games and I have been using the singleton pattern. Essentially for each object I create (player, levers, coins) I create a "controller" (singleton) script with essentially the variables and functions that I will need later for the actual scene script to consume. I'm not sure if what I'm doing is correct. I'm worried about later performance or code structure in general to turn into a mess. Any suggestions?

I noticed when using the autoload, if I call the script in a node within the game. Then it doesn't retain the singleton property of single instance.

What do you mean exactly?

@@GameDevWDavid So, you can attach the script to another node in the scene and try to get the data from that script instance. When you do, it will not be from the singleton instance. Which means it fails the restricted to on instantiation of the class. In the C example you showed, the "node" instance of the singleton would update the class variable _instance with a new instance. This however, will not happen in the auto-load and instead both instances will exist at the same time.

@@Sirlegna Yes, correct. It is not a Singleton in the pure sense of the technical term, but it is what we have for now in Godot.
