Using Interfaces in Game Development (Unity Tutorial)

Sign up for the Level 2 Game Dev Newsletter: eepurl.com/gGb8eP
In this video, you'll learn how to use interfaces in Unity3D and Game Development.
#Interfaces #Unity3D #GameDevelopment
The Interface is one of many programming concepts that can be utilized in both Unity3D and Game Development, in general. It's a powerful construct in object-oriented programming that grants you incredible flexibility through something called polymorphism. In this video, Jason Storey will help my alter ego, Barles, refactor his code so that it's more scalable and easier to maintain. Check out my channel, and consider subscribing, for more coding tutorials aimed at Unity3D and game development.

    As far as I could remember (and correct me if I'm wrong), the "I" in the interface is there since the C++ days. This is because they didn't have interfaces, so they used abstract classes with an "I" to denote that they are interfaces and fill in that class with virtual functions (or methods?) only, and ever since it got stuck with us I guess. I personally cannot imagine myself writing an interface without an "I" =P. Nevertheless, awesome video ;)

    The common struggle is "the approach". There may be multiple ways to do something thus we get stuck in "what is the most efficient one", often the answer is none and you're left with "There has to". Since most items that I would use interface for are inherently similar I end up making abstract class to inherit from, plus they can be serialized in the inspector, unlike an interface reference. Say I have a "SpawnedObject" script and it has a public reference to an "IItem" so I can assign an SO that implement the interface in the editor. It won't show up in the inspector, I can only assign it through code. If instead I have an "Item" class that "Lamp" has inherited from, I can link it in the inspector. Interface is mostly advantageous, IMHO, if both classes are significantly different and need a few common denominators for a method to work seemlessly between them OR to decouple your interaction system from the interactable system and you might want one or the other in a different game. Don't forget to bring the interface with it.

    I first came accross your channel maybe around 18 months ago? I have over a decade experience writing tools in Excel VBA and decided to leverage that knowledge to get into game development. When I first started watching your channel, I found the content to be a bit too dense for me (read: it went way over my head), so I followed along some Brackeys tutorials to help me understand the real basics of Unity and C#. After getting a feel for better designing my code, your content (which I've been viewing over the last month) is changing the game for me; both in VBA and C#. I'm writing better structured code, and if I get stuck, I google around for a bit until I stumble upon what feature I'm looking for, and you generally have very clear instructions on how it should be implemented. Thank you a heap! Your content is pure gold.

    This is hands down the best tutorial on interfaces out there, its 6 minutes, it very simply and clearly explains when to use them as well as how to use them, and then it even shows how to implement them into an existing problem. And i'm saying this as someone who went through 4 other tutorials having problems understanding what they were talking about, or not wanting to spend 40 minutes waiting for them to get to the point. Really wish more people made content this good.

This explanation makes complete sense to me, but your other video on 'SOLID Principles in Unity' that also dealt with Interfaces seemed confusing. Probably more so because of my inexperience than anything else. Anywho, thanks for the content! *Subscribed*
