( June 2017) SourceWritten inWebsiteSource is a 3D developed. It debuted as the successor to with in June 2004, followed shortly by in November, and has been in active development since.
Source does not have a concise scheme; instead, it is designed in constant incremental updates. The successor, Source 2, was officially announced in March 2015, with the first game to use it being, which was ported over from Source later that year. Contents.History Source distantly originates from the engine, itself a heavily modified version of 's. Carmack commented on his in 2004 that 'there are still bits of early Quake code in Half-Life 2'. Valve employee Erik Johnson explained the engine's on the Valve Developer Community:When we were getting very close to releasing (less than a week or so), we found there were already some projects that we needed to start working on, but we couldn't risk checking in code to the shipping version of the game.
At that point we off the code in to be both /$Goldsrc and /$Src. Over the next few years, we used these terms internally as 'Goldsource' and 'Source'.
At least initially, the Goldsrc branch of code referred to the codebase that was, and Src referred to the next set of more risky technology that we were working on. When it came down to show for the first time at, it was part of our internal communication to refer to the 'Source' engine vs. The 'Goldsource' engine, and the name stuck.Source was developed part-by-part from this fork onwards, slowly replacing GoldSrc in Valve's internal projects and, in part, explaining the reasons behind its unusually modular nature. Valve's development of Source since has been a mixture of licensed and in-house-developed code. Among others, Source uses for video playback. Modularity and notable upgrades Source was created to evolve incrementally with new technology, as opposed to the -breaking 'version jumps' of its competitors. Different systems within Source are represented by separate modules which can be updated independently.
With, Valve can distribute these updates automatically among its many users. In practice, however, there have been occasional breaks in this chain of compatibility. The release of and both introduced new versions of the engine that could not be used to run older games or without the developers performing upgrades to code and, in some cases, content.
Both cases required markedly less work to update its version than competing engines.Source 2006. A screenshot of. The and effects are evident.The Source 2006 branch was the term used for Valve's games using technology that culminated with the release of Half-Life 2: Episode One.
And were first implemented in 2005 using, which required the engine's shaders to be rewritten. The former, along with developer commentary tracks, were showcased in. Episode One introduced and other smaller features. Since the transition to Steam Pipe, this branch was made deprecated and is now used for backward compatibility with older mods. technology had been in development for, but was cut from the engine before its release. It was mentioned again by in 2006 as a piece of technology he would like to add to Source to implement support for much larger scenes that are impossible with strictly objects.
Source 2007 The Source 2007 branch represented a full upgrade of the Source engine for the release of The Orange Box. An artist-driven, threaded replaced previously effects for all of the games within. An in- tools framework was created to support it, which also supported the initial builds of. In addition, the facial animation system was made hardware-accelerated on modern video cards for 'feature film and broadcast television' quality. The release of The Orange Box on multiple platforms allowed for a large, which let the Source engine take advantage of multiple CPU cores.
However, support on the PC was experimental and unstable until the release of Left 4 Dead. Multiprocessor support was later backported to Team Fortress 2 and Day of Defeat: Source. Valve created the release of The Orange Box in-house, and support for the console is fully integrated into the main engine codeline. It includes asset converters, cross-platform play and integration.
Program code can be ported from PC to Xbox 360 simply by recompiling it. The release was outsourced to Electronic Arts, and was plagued with issues throughout the process.
Cited these issues when criticizing the console during the release of The Orange Box. Left 4 Dead branch The Left 4 Dead branch was a complete overhaul of the Source engine through the development of the.
Multiprocessor support was further expanded, allowing for features like split screen multiplayer, additional post-processing effects, event scripting with, and the highly-dynamic. The menu interface was re-implemented with a new layout designed to be more console-oriented. This branch later fueled the releases of and, the former released with source code outlining many of the changes made since the branch began.
Portal 2, in addition, served as the result of Valve taking the problem of porting to PlayStation 3 in-house, and in combination with integration creating what they called 'the best console version of the game'., and support In April 2010, Valve released all of their major Source games on OS X, coinciding with the release of the Steam client on the same platform. Valve announced that all their future games will be released simultaneously for Windows and Mac. The first of Valve's games to support Linux was, the port released in October 2012 along with the closed beta of the Linux version of Steam. Both the OS X and Linux ports of the engine take advantage of and are powered. During the process of porting, Valve rearranged most of the games released up to The Orange Box into separate, but parallel 'singleplayer' and 'multiplayer' branches. The game code to these branches was made public to mod developers in 2013, and they serve as the current stable release of Source designated for mods. Support for Valve's internal Steam Pipe distribution system as well as the are included.
In May 2014, released ports of Portal and Half-Life 2 to their -based Android. Tools and resources Source SDK. The launcher menu for Source SDKSource SDK is the for the Source engine, and contains many of the tools used by Valve to develop assets for their games. It comes with several command-line programs designed for special functions within the asset pipeline, as well as a few GUI-based programs designed for handling more complex functions. Source SDK was launched as a free standalone toolset through Steam, and required a Source game to be purchased on the same account. Since the release of Left 4 Dead in late 2008, Valve began releasing 'Authoring Tools' for individual games, which constitute the same programs adapted for each game's engine build.
After Team Fortress 2 became free-to-play, Source SDK was effectively made open to all Steam users. When some Source games were updated to Source 2013, the older Source SDKs were phased out. The three applications mentioned below are now included in the install of each game.There are three applications packaged in the Source SDK: Hammer Editor, Model Viewer, and Face Poser. Hammer Editor, the engine's official, uses rendering and compiling tools included in the SDK to create maps using the (BSP) method. The tool was originally known as Worldcraft and was developed independently by Ben Morris before Valve acquired it. The Model Viewer is a program that allows users to view models and can be used for a variety of different purposes, including development. Developers may use the program to view models and their corresponding animations, attachment points, bones, and so on.
Face Poser is the tool used to access facial animations and choreography systems. This tool allows one to edit, gestures and movements for characters, speech, and sequence expressions and other acting cues and preview what the scene will look like in the game engine.Source Dedicated Server The Source Dedicated Server or SRCDS is a standalone launcher for the Source engine that runs multiplayer game sessions without requiring a client. It can be launched through Windows or Linux, and can allow for custom levels and assets. Most third-party servers additionally run and SourceMod, which together provide a framework on top of SRCDS for custom modification of gameplay on existing titles.
Source Filmmaker. Main article:The Source Filmmaker (SFM) is a video capture and editing application that works from within the Source engine.
Developed by Valve, the tool was originally used to create movies for Day of Defeat: Source, but is more associated with Team Fortress 2. Today, it is open for public use and downloadable via the client.Destinations Workshop Tools In June 2016, Valve released the Destinations Workshop Tools, a set of free (VR) creation tools running using the Source 2 SDK. Valve Developer Community In June 2005, Valve opened the Valve Developer Community (VDC). VDC replaced Valve's static Source SDK documentation with a full -powered community site; within a matter of days Valve reported that 'the number of useful articles nearly doubled'. These new articles covered the previously undocumented, Valve's AI, advice for mod teams on setting up, and other articles.Academic papers Valve staff occasionally produce professional and/or academic papers for various events and publications, including, and, explaining various aspects of Source engine's development.

(2015). (2016). (2017)Source 2 As far back as May 2011, one of Valve's largest projects has been the development of new content authoring tools for Source. These would replace the current outdated tools, allowing content to be created faster and more efficiently. Newell has described the creation of content with the engine's current toolset as 'very painful' and 'sluggish'. Valve officially announced the engine at the in March 2015, also stating that it would be free to use for developers, with support for the. In addition, Valve confirmed that it would be using a new in-house named Rubikon.In June 2015, Valve announced that the entirety of would be ported over to Source 2 in an update called Dota 2 Reborn.
Reborn was first released to the public as an opt-in beta update that same month, and officially replaced the original client in September 2015, making it the first game to use the engine. The engine was also used for Valve's digital collectable card game, released in 2018, with a version of Source 2 created for and to support the game on those platforms., an upcoming (VR) game by Valve, will also use Source 2.
