You’re developing a game. How can you make it adaptable to different devices?

When developing a game, ensure its adaptability across various devices by choosing a cross-platform engine. This allows you to build your game once and deploy it on multiple platforms with minimal modifications. Popular options include Unity, Unreal Engine, Godot, and Cocos2d-x. These engines offer features and tools throughout the development process, from design and coding to testing and publishing, streamlining your work and reaching a wider audience.

Some of the most popular cross-platform engines are Unity, Unreal Engine, Godot, and Cocos2d-x. These engines offer various features and tools to help you design, code, test, and publish your game for different devices.

To reach a broad audience with minimal effort, use a cross-platform game engine like Unity or Unreal Engine. These engines let you build your game once and deploy it on many devices, saving you time and resources.

Choose an engine/platform that is top 2. You often need answers that you a thriving community that can help you. You don't want to get into a problem that has not been solved before. My suggestion - if not AAA - go Unity. if AAA - Go Unreal

Sometimes it will be unavoidable to have to design different UI's for different platforms. Its best to focus on you target platform and see how well it adapts to all the others.

you can use flexible layouts that adjust to the available space, scalable graphics that maintain their quality and proportion, and adaptive UI elements that change according to the device context. You can also use media queries to detect the device type and resolution and apply different styles or settings accordingly.

I look to the web for inspiration on how to handle different screen sizes. I feel like mouse & keyboard + controller support is largely a solved problem these days even though it takes a lot of work!

You should also balance the quality and quantity of lighting, shadows, particles, and post-processing effects. Finally, testing and profiling your game on different devices and platforms is essential for identifying and fixing bottlenecks and bugs.

Offering customization options for input settings like sensitivity, inversion, remapping, and calibration can also help. Last but not least, design your game mechanics and UI elements to suit different input methods like gestures, buttons, menus, and icons.

Considering the operating system (OS) of the device is an important factor for adaptability. Different operating systems have different features, requirements, and limitations that can affect your game development and deployment

It is important that you understand the different features and limitations of each platform you intend to distribute on - instead of rolling out to everything you can reach, you should limit to those you are able to test on, to ensure you don't let your product down by giving someone a poor experience on one of it's incarnations. Cross-platform SDKs (for example, OpenXR instead of Meta / Oculus SDK) are usually a good idea to build the skeleton of your game. This enables you to target more platforms without rewriting the whole project. Platform-specific tools , on the other hand, may be necessary to unlock unique features for a platform (such as hand tracking, in VR) or elevate the user experience for an individual platform.

Dependency Injection (DI) is key for engineers working on different platforms, like PC, console, VR, and mobile. It allows you to swap out platform-specific parts of your game easily. For example, if you have a game that needs platform-specific authentication or a different UI, DI lets you plug in that specific code depending on your needs. This way, you can use the same main game code across all platforms, but easily switch out the bits that need to be different for each one. It saves a lot of time and hassle, simplifying the process of making games that can run on various devices - with the added benefits of supporting code testing frameworks.
