Dependency Injection for Games

This repository contains the code accompanying the Dependency Injection for Games Medium article.

Repository Structure

The root folder contains the DependencyInjectionForGames.sln solution file, which references every project in the repository.

The Samples/ folder contains:

• DummyGameLibrary/: A library containing the systems that make up the dummy game application described in the article, such as Rendering or Physics. All systems are implemented as dummies, and will print their actions to the standard output for demonstration purposes. Please note that Rendering depends on the IGraphics interface, following the example introduced in the Dependency Inversion appendix.
• ManualInjectionSample/: The first executable of the dummy game application, which demonstrates how to manually setup Dependency Injection to organize the game systems defined in DummyGameLibrary/.
• ContainerInjectionSample/: The second executable of the dummy game application, which demonstrates how a Container can automate the process of setting up Dependency Injection. This topic is covered in the Injection Container appendix.

The behavior of the two game executables is intended to be the same: running the game for 2 frames before terminating.

The Container/ folder contains:

• Container/: A Dependency Injection Container library, such as the one presented in the Injection Container appendix.
• Test/: Unit tests for the Container library.
• README.md: Documentation for the Container library, including:
  • Feature overview;
  • Integration info;
  • Behind the scenes: theory and implementation details.
