Source É um motor gráfico 3D criado pela Valve em 2004, e é o sucessor da GoldSrc. O Motor Source é bem conhecido pelo seus avanços em física, IA, e gráficos que fizeram jogos realistas para seu tempo, ao mesmo tempo que é escalável em hardware mais antigo e menos potente. Half-Life 2 ganhou vários prêmios por seus gráficos, que foram possíveis graças ao Source. Source foi utilizada pela Valve(en), corporações de terceiros, e (parecido com a Goldsrc) incontáveis mods(en) feitos pela comunidade ao redor do globo, com pelo menos 100 jogos desenvolvidos na Source. O motor tem varias ramificações(en), cada uma contendo uma função adicionada e improvisando as capacidades gráficas.

Apesar do motor source estar na casa dos 20 anos, já sendo ultrapassado e substituído pelo Source 2 como motor principal partir de 2015. O motor continua sendo amplamente utilizado pela comunidade de modding e corporações de terceiros pelo fato da {{source2|4.1} não ter tantos documentos explicativos de utilização e raramente ser licenciado pela valve para desenvolvedores de terceiros comparado ao source, ainda sendo mantido regularmente com atualizações de segurança e ate mesmo melhorias para o próprio motor.

Clarify: Nem todos os jogos Source tem o . Veja Apex Legends.

Atenção: Counter-Strike: Global Offensive atualmente não suporta nível de detalhes (LoD). $lod(en) ira ser ignorado, entretanto o modelo ainda ira continuar a funcionando. Tente evitar de utilizar este comando no .

Sistema de Materiais(en)

• Instead of traditional textures, Source defines sets of materials that specify what the object is made from and the texture used for that object. A material specifies how an object will fracture when broken, what it will sound like when broken or dragged across another surface, and what that object's mass and buoyancy are. This system is much more flexible than other texture-only systems
• Materials can interact with objects or NPC(en)s, such as mud or ice for vehicles to slide/lose traction on

Multiplayer Network Code(en)

• Time- and gamer-tested by millions of gamers around the world
• Support for both LAN(en)-based multiplayer and Internet-based multiplayer games
• Prediction analysis for interpolating collision/hit detection
• Optimizations for high-latency, high-packet-loss 56k connections

• More responsive world with realistic interactions
• Sounds & graphics follow from physics
• AI characters can interact with physically simulated objects
• Ropes/cables, machines, constraint systems, ragdoll physics(en)

• AI senses things using sight, sound, and smell
• AI relationships(en) determine friend/foe status of other entities
• Battle AI allows squads of AI characters to operate together, know when to advance, retreat, lay cover fire, etc.

Sound System(en)

• 7.1, 5.1 surround sound, 4 speaker surround

Erro:On system running Windows Vista and later, due to the game engine using DirectSound and older version of Miles Sound System, the game may output only 5.1 surround despite 7.1 selected or 7.1 audio may not work properly without custom dsound.dll (such as Creative Alchemy, DSOAL or IndirectSound). This issue is not affected by some third-party games, such as Titanfall 2, Apex Legends as they used newer version of Miles Sound System.  [todo tested in ?]

Notar:Some or newer Source games (such as Alien Swarm, Portal 2 and Counter-Strike: Global Offensive) may not include options to enable 7.1 surround sound without using console commands.

• High-quality 3D spatialization
• Custom software DSP(en)
• Automatic DSP based on environmental geometry

• Support for audio streaming on any wave ^[Clarify]
• Real-time wave file stitching ^[Clarify]
• Pre-authored Doppler effect encoded waves
• Pre-authored distance variant encoded waves

UI(en)

Screenshot of Half-Life 2: Episode Two main menu, which is rendered using VGUI, with New Game, Options, and Achievements window opened.

Screenshot of VGUI's Gamepad UI used in some Source 2013 games after 2022. This UI was enabled by default when playing on Steam Deck.

• Server browser — Displays all active game servers and allows a player to choose which one to participate in. Players can filter and sort server lists to speed up the display and selection of a server.
• VGUI(en) — Valve's custom GUI interface mimics most of the Windows controls but is rendered using the Source engine for both in game and out of game uniform UI display. Some features:
  • Dynamic in-game HUD(en) display
  • Many widgets(en)/controls (e.g., buttons, treeview, html control…)
  • Themes/custom visualization allowed
  • Platform independent
  • Localized text (Unicode compliant)
  • Gamepad UI(en) ( Source 2013 version) — Since the release of Half-Life 2 (and its episodes) as well as Portal updates in 2022, Valve have added a modern UI which is designed for consoles and handhelds like Steam Deck. With the new Gamepad UI, it was more scalable across any resolution (including 4K and higher), unlike the regular VGUI (which, the higher the resolution, the text and UI will become smaller). This UI can be also enabled manually by using -gamepadui command line argument(en) (which will also enable Vulkan(en) renderer that may not work on some older GPUs unless -dx9 is used in combination of -gamepadui).
• Scaleform (officially called Scaleform GFx) — Introduced with CS:GO engine branch at launch until 2018, this is a vector graphics rendering engine used to display Adobe Flash-based UI and HUD for games.
• Panorama(en) (em todos os jogos desde ) — Introduced in 2018, replacing Scaleform, Valve's new Custom GUI interface that resembles modern web design and authoring (HTML5/CSS/JS). Using .XML and JavaScript files, developers can create dynamic and clean HUDs and menus and even high-quality in-game intractable panels.

Programming(en)

• Source natively support various CPU architectures, such as x86 (PC and 8th, 9th-gen Consoles), ARM ( Android, Nintendo Switch), PowerPC ( Xbox 360, PlayStation 3), and more, with both 32 and 64-bit(en).
  • Support for 64-bit(en) architecture will allow Source to handle more than 2-4GB of RAM limit.
  • Historically, Half-Life 2 had a 64-bit(en) update in 2005, but it was later removed for unknown reasons. CS:GO later received an 64-bit(en) update in 2016 for Mac and Linux systems. On April 19, 2024, Team Fortress 2 was upgraded to 64-bit(en) on Windows and Linux.
• All code written in C/C++ using Visual Studio(en) .NET 2003 and later. Easily and quickly derive new entities from existing base classes
  • Source SDK 2013(en) code, by default, can be compiled on Visual Studio 2013 only. See Compiling under VS2022(en) if you want to compile Source 2013 with newer versions of Visual Studio.
  • Linux version are compiled using GNU Compiler Collection(en).
• Internal context sensitive performance monitoring system
• Graphics performance measurement tools built into the engine
• Modular code design (via DLLs) allows swapping out of core components for easy upgrading or code replacement
• VScript(en) scripting system allows using external coding languages, such as Squirrel and Lua, in maps to create more complex systems (em todos os jogos desde ) (também em )

Remake of Counter-Strike. Hidden Path Entertainment alongside Valve worked on the May 7, 2010 update, which upgraded the game's engine from Source 2006 to 2009 (MP version, later renamed to Source MP), and added 144 (now 146) achievements, a new domination and revenge system similar to Team Fortress 2, player stats and more. Hidden Path Entertainment also worked on the unreleased Xbox 360 port of CS:S, which would later become Counter-Strike: Global Offensive after Valve saw the opportunity during its development to turn the port into a new game. Mac version of the game was later release in June 2010, and Linux in 2013.
16 nov. 2004	Half-Life: Source		Source 2004 (launch) Source 2013 Singleplayer (currently)	PC: Windows, Mac, Linux	Remaster of Half-Life. It is critically panned by most gamers since 2013 due to the huge amount of bugs that were introduced when the game was updated to Source 2013. Prior to the 2013 update, it received mixed reviews by critics and most gamers, some players are disappointed over the game graphics (especially the textures) that are unchanged from the original, while also having a realistic Source's 3D Skybox and water effects. A unofficial fan remake of Half-Life, called Black Mesa was later started development in response of those criticisms, which was first released in 2012 without any Xen chapters and was much shorter, and later in 2020, a full release with contains the Xen chapters.
