![]() Dependency Injection (DI) is a design pattern in which an object receives other objects that it depends on. A class doesn't know where it's dependencies came from and doesn't even need to pass dependencies to any child objects it creates. ⭐️ There are four roles an object may play in Dependency Injection. 📌 Service - The dependency or object to be used. 📌 Client - The object that is using and depending on the service. 📌 Interface - Defines how the client can use the service. 📌 Injector - The object responsible for constructing the services and injecting them into the client. ⭐️ If you're confused, no worries, here are examples of all the roles 📌 Service - Class Retriever, implements the IDog interface. 📌 Client - Class Walk, requires an IDog object. 📌 Interface - IDog, defines the methods for all Dogs. 📌 Injector - MyInjector, creates the correct type of dog and injects it. ⭐️ The power behind this design pattern is the loose coupling architecture. 💻 We could easily create a new type of dog, Pug, inject it, and the Walk class will work fine. 💻 Passing dependencies as arguments are no longer required. 💻 All dependency logic is offloaded into Injectors, allowing Dog to focus on being a dog. 💻 DI allows for factories to be injected also. ➡️ There is sometimes a performance cost depending on the implementation. ➡️ DI assets exist for Unity, we'll be covering this soon.
