Microsoft DirectX is a collection of application programming interfaces (APIs) for handling tasks related to multimedia, especially game programming and video, on Microsoft platforms. Originally, the names of these APIs all began with "Direct", such as Direct3D, DirectDraw, DirectMusic, DirectPlay, DirectSound, and so forth. The name DirectX was coined as a shorthand term for all of these APIs and soon became the name of the collection. When Microsoft later set out to develop a gaming console, the X was used as the basis of the name Xbox to indicate that the console was based on DirectX technology. The X initial has been carried forward in the naming of APIs designed for the Xbox such as XInput and the Cross-platform Audio Creation Tool (XACT), while the DirectX pattern has been continued for Windows APIs such as Direct2D and DirectWrite.
Wine is a free and open-source compatibility layer that aims to allow application software and computer games developed for Microsoft Windows to run on Unix-like operating systems. Wine also provides a software library, named Winelib, against which developers can compile Windows applications to help port them to Unix-like systems.
In computing, cross-platform software is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms.
A computing platform or digital platform is an environment in which a piece of software is executed. It may be the hardware or the operating system (OS), even a web browser and associated application programming interfaces, or other underlying software, as long as the program code is executed with it. Computing platforms have different abstraction levels, including a computer architecture, an OS, or runtime libraries. A computing platform is the stage on which computer programs can run.
Microsoft XNA is a freeware set of tools with a managed runtime environment that Microsoft developed to facilitate video game development. XNA is based on .NET Framework, with versions that run on Windows and Xbox 360. XNA Game Studio can help develop XNA games. The XNA toolset was announced on March 24, 2004, at the Game Developers Conference in San Jose, California. A first Community Technology Preview of XNA Build was released on March 14, 2006.
Game programming, a subset of game development, is the software development of video games. Game programming requires substantial skill in software engineering and computer programming in a given language, as well as specialization in one or more of the following areas: simulation, computer graphics, artificial intelligence, physics, audio programming, and input. For multiplayer games, knowledge of network programming is required. In some genres, e.g. fighting games, advanced network programming is often demanded, as the netcode and its properties are considered by players and critics to be some of the most important metrics of the game's quality. For massively multiplayer online games (MMOGs), even further knowledge of database programming and advanced networking programming are required. Though often engaged in by professional game programmers, there is a thriving scene of independent developers who lack a relationship with a publishing company.
Steam is a video game digital distribution service and storefront by Valve. It was launched as a software client in September 2003 as a way for Valve to provide automatic updates for their games, and expanded to distributing and offering third-party game publishers' titles in late 2005. Steam offers various features, like digital rights management (DRM), game server matchmaking, anti-cheat measures, social networking and game streaming services. It provides the user with automatic game updating, saved game cloud synchronization, and community features such as friends messaging, in-game chat and a community market.
GameSpy was an American provider of online multiplayer and matchmaking middleware for video games founded in 1996 by Mark Surfas. After the release of a multiplayer server browser for the game, QSpy, Surfas licensed the software under the GameSpy brand to other video game publishers through a newly established company, GameSpy Industries, which also incorporated his Planet Network of video game news and information websites, and GameSpy.com.
Xfire was a proprietary freeware instant messaging service for gamers that also served as a game server browser with various other features. It was available for Microsoft Windows.
Mac gaming refers to the use of video games on Macintosh personal computers. In the 1990s, Apple computers did not attract the same level of video game development as Microsoft Windows computers due to the high popularity of Microsoft Windows and, for 3D gaming, Microsoft's DirectX technology. In recent years, the introduction of Mac OS X and support for Intel processors has eased porting of many games, including 3D games through use of OpenGL and more recently Apple's own Metal API. Virtualization technology and Boot Camp also permit the use of Windows and its games on Macintosh computers. Today, a growing number of popular games run natively on macOS, though as of early 2019, a majority still require the use of Microsoft Windows.
Games for Windows is a discontinued brand owned by Microsoft and introduced in 2006 to coincide with the release of the Windows Vista operating system. The brand itself represents a standardized technical certification program and online service for Windows games, bringing a measure of regulation to the PC game market in much the same way that console manufacturers regulate their platforms. The branding program was open to both first-party and third-party publishers.
Linux gaming refers to playing video games on a Linux operating system. Because many games are not natively supported for the Linux kernel, various software has been made to run Windows games, such as Wine, Proton, and Lutris. The Linux gaming community has a presence on the internet with users who attempt to run games that are normally not supported on Linux. This includes a subreddit which has over 240k members as of January 2023.
Open Cobalt is a free and open-source software platform for constructing, accessing, and sharing virtual worlds both on local area networks or across the Internet, with no need for centralized servers.
Game Sprockets is a collection of application programming interfaces (APIs) supporting gaming on the classic Mac OS. It consisted of four main parts, DrawSprocket, InputSprocket, SoundSprocket and NetSprocket, each providing a library of pre-rolled routines for common gaming tasks. SpeechSprocket was a relabelled version of the Speech Recognition Manager that provided speech recognition support, and QuickDraw 3D RAVE provided 3D hardware acceleration.
Universal Windows Platform (UWP) is a computing platform created by Microsoft and first introduced in Windows 10. The purpose of this platform is to help develop universal apps that run on Windows 10, Windows 10 Mobile (discontinued), Windows 11, Xbox One, Xbox Series X/S, and HoloLens without the need to be rewritten for each. It supports Windows app development using C++, C#, VB.NET, and XAML. The API is implemented in C++, and supported in C++, VB.NET, C#, F# and JavaScript. Designed as an extension to the Windows Runtime (WinRT) platform first introduced in Windows Server 2012 and Windows 8, UWP allows developers to create apps that will potentially run on multiple types of devices.
Amazon Lumberyard is a now-superseded freeware cross-platform game engine developed by Amazon and based on CryEngine, which was licensed from Crytek in 2015. In July 2021, Amazon and the Linux Foundation announced that parts of the engine would be used to create a new open source game engine called Open 3D Engine, which would replace it. A new Open 3D Foundation, run by the Linux Foundation, will manage the new engine, which will be licensed under the open source Apache 2.0 license. The new engine is reportedly partially based on Lumberyard but with many parts rewritten, and is considered a new engine.
In video games with online gaming functionality, also called cross-compatible play, cross-platform play, crossplay, or cross-play describes the ability of players using different video game hardware to play with each other simultaneously. It is commonly applied to the ability for players using a game on a specific video game console to play alongside a player on a different hardware platform such as another console or a computer. A related concept is cross-save, where the player's progress in a game is stored in separate servers, and can be continued in the game but on a different hardware platform.
