During the GDC 2019 Game Developers Conference, Google unveiled its ambitious game streaming service, Stadia, which we're slowly starting to learn more about. In particular, Unity, represented by lead engineer Nick Rapp, decided to reveal that it is going to add official support for the Stadia platform to its popular game engine.
For example, when creating games for Stadia, developers will be able to use all the tools familiar today, such as Visual Studio, Renderdoc, Radeon Graphics Profiler. At the same time, Unity will acquire support for all the unique features of Stadia (extended cross-platform, the ability to call the Google Assistant in the game, the ability to direct the player directly to a certain part of the game through State Share, and so on) and the official process for publishing games for the Google streaming platform. Unity will talk more about this later.
Google has already begun working with a number of partners and studios through an early release of the Stadia SDK, and will continue to engage developers throughout 2019. Regular Unity developers can expect access to Stadia features before the end of the year. Existing games can be ported to Stadia but will need to be updated to the latest version of Unity.
Google Stadia will rely on Vulkan's low-level graphics API and its own Linux-based operating system, so developers should keep that in mind. Also, Unity for Stadia will evolve around the IL2CPP scripting technology, so the game code must be compatible.
