Submitting to Windows Store

Building a Windows Store-ready Windows 8 game with GameMaker:Studio is easy. With the recent launch of the Windows 8 now is the time to get your game in the store. Here are the three key development steps to building, testing and publishing your game to the Windows Store.

Getting Started

Before you get started building your Windows 8 game with GameMaker:Studio you need to make sure that you have done the following:

  • Download and install Windows 8 - You can download a 90 day FREE evaluation version of Windows 8 from the Evaluation Center.
  • Download Visual Studio Here and install it in Windows 8. NOTE: If you are an MSDN subscriber; you can get Windows 8 and Visual Studios from MSDN Subscriber Downloads.

Become a Windows Store Developer - Sign up for your Windows Store Account and reserve your game name today.

  • If you are an MSDN subscriber you can get a free one-time, 12-month Windows Store account here.
  • If you are a student then the subscription fee is waived.
  • If you are a startup or small business then you are eligible to get a free one-time, 12-month Windows Store account here

We also recommend that you check out the Microsoft Windows 8 Developers Guide for information and expert recommendations on how to create and monetize Windows 8 apps, leveraging their key features such as Live Tiles and Share as well as how to setup selling and advertising features. You can also get an overview of these features and their implementation within GameMaker:Studio by loading up and testing the Windows 8 demo file that is included (run GameMaker:Studio, select "Demos" from the start-up screen and look for the one marked "Windows 8").

Create Certificate

When submitting to the store a Store Certificate must be generated. This is done by first of all reserving a name on the Windows Store and setting up the game name for the store. Once this is done you will need to download Visual Studio for Windows 8 from Microsoft.

When this is installed and you are signed in, create a new Store project named whatever you wish then click Store menu at the top and select 'Associate with Store'. The window should show the game names you have reserved on the Windows Store, click the one you wish to use, click next then click associate.

This should then create a new file in the project called *projectname*_storekey, change the name of this to reflect the name of your GameMaker Project and publisher name, eg: yoyogames.simplysolitaire_storekey, then copy this to your project directory.

You will then need to set this as the certificate for your GameMaker Project by going to Global Game Settings, selecting the Windows 8 options then selecting the Installation tab at the left hand side. Click '...' to navigate to your new certificate then click the Install button.

You now need to Create the Windows 8 application.

Once this is all done you should be able to submit the game to the Windows Store.

Building And Testing Your Game

To be able to build you game in GameMaker:Studio and test the unique Windows 8 functions you will have to make sure the the following requirement has been met:

Setup your Developer Key - The Developer Key is essential to creating a Windows 8 app to generate you must set up the Preferences correctly in GameMaker:Studio. You can find detailed instructions on the page Preparing GameMaker:Studio for Windows 8.

It is also a good idea to review some of the videos and design articles that have been made available to you from other game developers here, as well as ensure that your game complies with the Windows 8 Certification Requiremnts.

Finally, you should download the Windows App Certification Kit, which is a tool you can use to help your game pass Windows Store certification process, which includes testing your game.
