UnrealDI

Dependency Injection container for Unreal Engine. Container will take care of objects creation and their lifetime.

This implementation works on top of UObjects and UInterfaces.

Getting started

First, you need to setup your container and register some types into it:

// create builder object
FContainerBuilder Builder;

// register type UMyService as implementation of IMyService interface
Builder.RegisterType<UMyService>().As<IMyService>();

// create container itself
UObjectContainer* Container = Builder.Build();

After that you can ask it to resolve some instances:

TScriptInterface<IMyService> MyService = Container->Resolve<IMyService>();

Supported versions

Latest release of UnrealDI requires at least Unreal 5.1. For Unreal version 5.0 and below, please use Unreal DI v1.5.0
I test this plugin to work with the latest version of Unreal Engine and two versions before it. If you have any issues, please submit them here

Acknowledgment

UnrealDI is heavily inspired by Hypodermic, but designed with Unreal Engine specifics in mind.
