Source 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 em que é escalável em versões mais antigas, hardware menos potente. Um jogo, Half-Life 2, ganhou vários prêmios por seus gráficos, que foram possíveis graças a Source. Source foi usada pela Valve(en), corporações de terceiros, e (muito parecido com a GoldSrc) incontáveis mods(en) feitos pelas pessoas das comunidades ao redor do globo, com pelo menos 100 jogos desenvolvidos na Source. O motor que tem varias extensões(en), cada com uma nova função adicionada e improvisando as capacidades gráficas.

Apesar do Motor Source já estar na casa dos 20 anos, e já sendo ultrapassado pelo Source 2 Source 2 sendo utilizado como motor principal partir de 2015, ela esta a ser usada comumente ate os dias de hoje por modders e algumas corporações de terceiros pelo fato da Source 2 não ter tantos documentos explicativos e era raramente licenciada para desenvolvedores de terceiros comparado a Source, e ainda sendo mantida ate hoje com atualizações regulares de segurança e ate mesmo para o próprio motor.

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

Recursos

Lista de recursos e capacidades para o motor Source Source. Alguns recursos novos listados aqui podem não se aplicar para segmentos antecessores ou superiores da Source, ou jogos/ramificações de terceiros.

Warning.pngAtenção:Counter-Strike: Global Offensive Counter-Strike: Global Offensive currently does not support level of detail. $lod(en) will be ignored, but the model will still work. Try to avoid using this command in Counter-Strike: Global Offensive.

Materials System(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

  • Detailed and believable characters
  • Realistic eyes(en)
    • Focus on player/object, not simply parallel views
    • Proper eye bulge for realistic eye reflections

  • 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)

  • Kinematic animated bone followers
  • Custom procedural physics controllers
  • Vehicles
    • Wheels slip and skid
    • Realistic suspensions with springs on each wheel
    • Realistic leaning during acceleration/deceleration and turning
    • Individually tunable parameters such as horsepower, gearing, max speed, shift speed, tire material, tire friction, spring tension/dampening, etc.
    • Multiple players in a vehicle in multiplayer
    • Hovercraft support for cheaper simulation

Advanced AI(en)

  • I/O system(en) allows level designers to control AI
  • Sophisticated navigation: characters that run, fly, jump, crouch, climb stairs and ladders, and burrow underground
  • 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
Icon-Bug.pngErro: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?]
Note.pngNota: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
  • Microsoft ADPCM-compressed WAV(en) files

  • 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 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 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) (no translation Counter-Strike: Global Offensive) — 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 Android, Nintendo Switch Nintendo Switch), PowerPC (Xbox 360 Xbox 360, PlayStation 3 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
  • 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 (no translation Left 4 Dead 2) (no translation Team Fortress 2Mapbase)
