Developing Marble Maze, a UWP game in C++ and DirectX
This topic describes how to use DirectX and Visual C++ to create a 3D Universal Windows Platform (UWP) game. The game, called Marble Maze, embraces multiple form factors such as tablets as well as traditional desktop and laptop PCs.
To download the Marble Maze source code, see the sample on GitHub.
Marble Maze illustrates design patterns that we consider to be best practices for creating UWP games. You can adapt many of the implementation details to fit your own practices and the unique requirements of the game you are developing. Feel free to use different techniques or libraries when those better suit your needs. (However, always ensure that your code passes the Windows App Certification Kit.) When we consider an implementation used here to be essential for successful game development, we emphasize it in this documentation.
Introducing Marble Maze
We chose Marble Maze because it is relatively basic, but still demonstrates the breadth of features that are found in most games. It shows how to use graphics, input handling, and audio. It also demonstrates game mechanics such as rules and goals.
Marble Maze resembles the table-top labyrinth game that is typically constructed from a box that contains holes and a steel or glass marble. The goal of Marble Maze is the same as the table-top version: tilt the maze to guide the marble from the start to the end of the maze in as little time as possible, without letting the marble fall into any of the holes. Marble Maze adds the concept of checkpoints. If the marble falls into a hole, the game is restarted at the last checkpoint location that the marble passed over.
Marble Maze offers multiple ways for a user to interact with the game board. If you have a touch-enabled or accelerometer-enabled device, you can use those devices to move the game board. You can also use an Xbox One controller or a mouse to control game play.

Who should read this?
If you’re interested in creating 3D games or other graphics-intensive applications for Windows 10, this is for you. We hope you use the principles and practices that this documentation outlines to create your own UWP game. A background or strong interest in C++ and DirectX programming will help you get the most out of this documentation. If you don't have experience with DirectX, you can still benefit if you have experience with similar 3D graphics programming environments.
The document Walkthrough: create a simple UWP game with DirectX describes another sample that implements a basic 3D shooting game by using DirectX and C++.
What this documentation covers
This documentation teaches how to:
- Use the Windows Runtime API and DirectX to create a UWP game.
- Use Direct3D and Direct2D to work with visual content such as models, textures, vertex and pixel shaders, and 2D overlays.
- Integrate input mechanisms such as touch, accelerometer, and the Xbox One controller.
- Use XAudio2 to incorporate music and sound effects.
What this documentation does not cover
This documentation does not cover the following aspects of game development. These aspects are followed by additional resources that cover them.
- 3D game design principles.
- C++ or DirectX programming basics.
- How to design resources such as textures, models, or audio.
- How to troubleshoot behavior or performance issues in your game.
- How to prepare your game for use in other parts of the world.
- How to certify and publish your game to the Microsoft Store.
Marble Maze also uses the DirectXMath library to work with 3D geometry and perform physics calculations, such as collisions. DirectXMath is not covered in-depth in this section. For details about how Marble Maze uses DirectXMath, refer to the source code.
Although Marble Maze provides many reusable components, it is not a complete game development framework. When we consider a Marble Maze component to be reusable in your game, we emphasize it in the documentation.
We recommend that you start with Marble Maze sample fundamentals to learn about the Marble Maze structure and some of the coding and style guidelines that the Marble Maze source code follows. The following table outlines the documents in this section so that you can more easily refer to them.
