85-473: Unity is a cross-platform game engine developed by Unity Technologies , first announced and released in June 2005 at Apple Worldwide Developers Conference as a Mac OS X game engine. The engine has since been gradually extended to support a variety of desktop , mobile , console , augmented reality , and virtual reality platforms. It is particularly popular for iOS and Android mobile game development,

170-516: A 3D content creation tool and exporting the scene to a format that is readable by the viewer or helper library. Desktop 3D authoring software such as Blender , Autodesk Maya or SimLab Composer can be used for this purpose. In particular, Blend4Web allows a WebGL scene to be authored entirely in Blender and exported to a browser with a single click, even as a standalone web page. There are also some WebGL-specific software such as CopperCube and

255-420: A fat binary . The use of different toolsets may not be enough to build a working executables for different platforms. In this case, programmers must port the source code to the new platform. For example, an application such as Firefox, which already runs on Windows on the x86 family, can be modified and re-built to run on Linux on the x86 (and potentially other architectures) as well. The multiple versions of

340-583: A JVM. Java software can be executed by a hardware-based Java processor . This is used mostly in embedded systems. Java code running in the JVM has access to OS-related services, like disk input/output (I/O) and network access, if the appropriate privileges are granted. The JVM makes the system calls on behalf of the Java application. This lets users to decide the appropriate protection level, depending on an access-control list (ACL). For example, disk and network access

425-436: A Preferred Platform License from the console manufacturer. The Unity Pro keys would have been part of the other SDK from the console manufacturer that the developer paid for. In May 2016, Unity released "Unity Plus", a mid-range tier between Personal and Pro that provides tools and benefits oriented towards "first-time commercial developers". In June 2021, Unity changed its licensing terms to require any developer making games on

510-452: A Web browser plugin. However, it was deprecated in favor of WebGL . Since version 5, Unity has been offering its WebGL bundle compiled to JavaScript using a 2-stage language translator ( C# to C++ and finally to JavaScript ). Unity was the default software development kit (SDK) used for Nintendo's Wii U video game console , with a free copy included by Nintendo with each Wii U developer license. Unity Technologies called this bundling of

595-442: A client/web-server architecture. The distinction between traditional and web applications is not always clear. Features, installation methods and architectures for web and traditional applications overlap and blur the distinction. Nevertheless, this simplifying distinction is a common and useful generalization. Traditional application software has been distributed as binary files, especially executable files . Executables only support

680-483: A game with the intention of release on the latest Nintendo and Sony game consoles. Should Disney license the game with Sony first, it may be required to release the game solely on Sony's console for a short time or indefinitely . Several developers have implemented ways to play games online while using different platforms. Psyonix , Epic Games , Microsoft , and Valve all possess technology that allows Xbox 360 and PlayStation 3 gamers to play with PC gamers, leaving

765-485: A language similar to C or C++ . WebGL code is executed on a computer's GPU. WebGL is designed and maintained by the non-profit Khronos Group . On February 9, 2022, Khronos Group announced WebGL 2.0 support from all major browsers. WebGL 1.0 is based on OpenGL ES 2.0 and provides an API for 3D graphics. It uses the HTML5 canvas element and is accessed using Document Object Model (DOM) interfaces. WebGL 2.0

850-645: A particular platform—either the hardware, OS, or virtual machine (VM) it runs on. For example, the Java platform is a common VM platform which runs on many OSs and hardware types. A hardware platform can refer to an instruction set architecture . For example: ARM or the x86 architecture. These machines can run different operating systems. Smartphones and tablets generally run ARM architecture, these often run Android or iOS and other mobile operating systems . A software platform can be either an operating system (OS) or programming environment , though more commonly it

935-404: A project called X3DOM to make X3D and VRML content run on WebGL. There has been an emergence of 2D and 3D game engines for WebGL, such as Unreal Engine 4 and Unity . The Stage3D /Flash-based Away3D high-level library also has a port to WebGL via TypeScript . A more light-weight utility library that provides just the vector and matrix math utilities for shaders is sylvester.js. It

1020-600: A specific revenue threshold). Unity subsequently issued a statement clarifying the definition of a chargeable "installation", and announced that the fee would not apply to charity games or bundles. Many indie developers, including Among Us developer Innersloth and Slay the Spire developer Mega Crit, announced that they would switch to other game engines. An analysis by Ars Technica found that several older versions of Unity's terms of service would allow developers to continue to release their software without having to pay

1105-482: A third-party SDK an "industry first". In August 2023, Unity China announced that it would soon launch a Chinese edition called Tuanjie Engine ( Chinese : 团结引擎 ; pinyin : Tuánjié Yǐnqíng ) based on Unity 2022 LTS, which includes support for Chinese platforms like Weixin Mini Game, OpenHarmony and AliOS . During its first ten years as a product, the paid versions of Unity were sold outright; in 2016,

1190-443: A third. While this is straightforward, compared to developing for only one platform it can cost much more to pay a larger team or release products more slowly. It can also result in more bugs to be tracked and fixed. Another approach is to use software that hides the differences between the platforms. This abstraction layer insulates the application from the platform. Such applications are platform agnostic . Applications that run on

1275-527: A time-consuming task because different OSs have different application programming interfaces (API). Software written for one OS may not automatically work on all architectures that OS supports. Just because software is written in a popular programming language such as C or C++ , it does not mean it will run on all OSs that support that language—or even on different versions of the same OS. Web applications are typically described as cross-platform because, ideally, they are accessible from any web browser :

1360-679: A version control system to allow developers to collaborate more easily. It included a Networking Layer for developers to create multiplayer games based on the User Datagram Protocol , offering Network Address Translation , State Synchronization, and Remote Procedure Calls . When Apple launched its App Store in 2008, Unity added support for the iPhone . Unity 2.5, released in March, 2009, added editor support for Windows . Unity 3.0 launched in September 2010 with features expanding

1445-469: A workaround for this problem. Tools such as the Page Object Model allow cross-platform tests to be scripted so that one test case covers multiple versions of an app. If different versions have similar user interfaces, all can be tested with one test case. Web applications are becoming increasingly popular but many computer users still use traditional application software which does not rely on

1530-700: Is IBM PowerVM Lx86 , which allows Linux/x86 applications to run unmodified on the Linux/Power OS. Example of cross-platform binary software: A script can be considered to be cross-platform if its interpreter is available on multiple platforms and the script only uses the facilities built into the language. For example, a script written in Python for a Unix-like system will likely run with little or no modification on Windows, because Python also runs on Windows; indeed there are many implementations (e.g. IronPython for .NET Framework ). The same goes for many of

1615-418: Is a combination of both. An exception is Java , which uses an OS-independent virtual machine (VM) to execute Java bytecode . Some software platforms are: The Java language is typically compiled to run on a VM that is part of the Java platform. The Java virtual machine (Java VM, JVM) is a CPU implemented in software, which runs all Java code. This enables the same code to run on all systems that implement

1700-516: Is a term that can also apply to video games released on a range of video game consoles . Examples of cross-platform games include: Miner 2049er , Tomb Raider: Legend , FIFA series , NHL series and Minecraft . Each has been released across a variety of gaming platforms, such as the Wii , PlayStation 3 , Xbox 360 , personal computers , and mobile devices . Some platforms are harder to write for than others, requiring more time to develop

1785-581: Is also developing solutions in the fields of architecture, engineering, and construction. Unity's engine is used by DeepMind , an Alphabet Inc. company, to train artificial intelligence. Other uses being pursued by Unity Technologies include architecture, engineering, and construction. On December 16, 2013, Unity Technologies Japan revealed an official mascot character named Unity-chan ( ユニティちゃん , Yuniti-chan ) , real name Kohaku Ōtori ( 大鳥 こはく , Ōtori Kohaku ) (voiced by Asuka Kakumoto  [ ja ; zh ] ). The character's associated game data

1870-430: Is available on Windows, macOS (both PowerPC and x86 through what Apple Inc. calls a Universal binary ), Linux, and BSD on multiple computer architectures. The four platforms (in this case, Windows, macOS, Linux, and BSD) are separate executable distributions, although they come largely from the same source code . In rare cases, executable code built for several platforms is combined into a single executable file called

1955-627: Is based on OpenGL ES 3.0 . It guarantees the availability of many optional extensions of WebGL 1.0, and exposes new APIs. Automatic memory management is provided implicitly by JavaScript . Like OpenGL ES 2.0, WebGL lacks the fixed-function APIs introduced in OpenGL 1.0 and deprecated in OpenGL 3.0. This functionality, if required, has to be implemented by the developer using shader code and JavaScript. Shaders in WebGL are written in GLSL and passed to

2040-615: Is considered easy to use for beginner developers, and is popular for indie game development. The engine can be used to create three-dimensional (3D) and two-dimensional (2D) games, as well as interactive simulations . The engine has been adopted by industries outside video gaming, such as film , automotive , architecture , engineering , construction , and the United States Armed Forces . The Unity game engine launched in 2005, aiming to "democratize" game development by making it accessible to more developers. It

2125-448: Is separation of functionality, which disables functionality not supported by browsers or OSs, while still delivering a complete application to the user. (See also: Separation of concerns .) This technique is used in web development where interpreted code (as in scripting languages) can query the platform it is running on to execute different blocks conditionally. Third-party libraries attempt to simplify cross-platform capability by hiding

2210-541: Is sometimes used in conjunction with a WebGL specific extension called glUtils.js. There are also some 2D libraries built atop WebGL, like Cocos2d -x or Pixi.js , which were implemented this way for performance reasons in a move that parallels what happened with the Starling Framework over Stage3D in the Flash world. The WebGL-based 2D libraries fall back to HTML5 canvas when WebGL is not available. Removing

2295-547: Is the practice of deliberately writing software to work on more than one platform. There are different ways to write a cross-platform application. One approach is to create multiple versions of the same software in different source trees —in other words, the Microsoft Windows version of an application might have one set of source code files and the Macintosh version another, while a FOSS *nix system might have

2380-411: Is used with this technique. Cross-platform applications need much more integration testing . Some web browsers prohibit installation of different versions on the same machine. There are several approaches used to target multiple platforms, but all of them result in software that requires substantial manual effort for testing and maintenance. Techniques such as full virtualization are sometimes used as

2465-764: Is usually enabled for desktop applications, but not for browser-based applets . The Java Native Interface (JNI) can also be used to access OS-specific functions, with a loss of portability. Currently, Java Standard Edition software can run on Microsoft Windows, macOS, several Unix-like OSs, and several real-time operating systems for embedded devices. For mobile applications, browser plugins are used for Windows and Mac based devices, and Android has built-in support for Java. There are also subsets of Java, such as Java Card or Java Platform, Micro Edition , designed for resource-constrained devices. For software to be considered cross-platform, it must function on more than one computer architecture or OS. Developing such software can be

2550-745: The Vulkan graphics API . It introduced a 4K video player capable of running 360-degree videos for virtual reality. However, some gamers criticized Unity's accessibility due to the high volume of quickly produced games published on the Steam distribution platform by inexperienced developers. Former CEO John Riccitiello said in an interview that he believes this to be a side-effect of Unity's success in democratizing game development: "If I had my way, I'd like to see 50 million people using Unity – although I don't think we're going to get there any time soon. I'd like to see high school and college kids using it, people outside

2635-563: The non-profit technology consortium Khronos Group started the WebGL Working Group, with initial participation from Apple , Google , Mozilla, Opera , and others. Version 1.0 of the WebGL specification was released March 2011. An early application of WebGL was Zygote Body . In November 2012 Autodesk announced that they ported most of their applications to the cloud running on local WebGL clients. These applications included Fusion 360 and AutoCAD 360. Development of

2720-422: The open-source scripting languages . Unlike binary executable files, the same script can be used on all computers that have software to interpret the script. This is because the script is generally stored in plain text in a text file . There may be some trivial issues, such as the representation of a new line character . Some popular cross-platform scripting languages are: Cross-platform or multi-platform

2805-602: The 2017 Unite Europe conference in Amsterdam, Unity focused on filmmaking with Unity 2017.1's new Cinemachine tool. In 2018, Disney Television Animation launched three shorts, called Baymax Dreams, that were created using the Unity engine. The Unity engine was also used by Disney to create backgrounds for the 2019 film The Lion King . Automakers use Unity's technology to create full-scale models of new vehicles in virtual reality, build virtual assembly lines, and train workers. Unity

2890-583: The JVM are built this way. Some applications mix various methods of cross-platform programming to create the final application. An example is the Firefox web browser, which uses abstraction to build some of the lower-level components, with separate source subtrees for implementing platform-specific features (like the GUI), and the implementation of more than one scripting language to ease software portability . Firefox implements XUL , CSS and JavaScript for extending

2975-548: The Nvidia PhysX 3.3 physics engine. The fifth generation of the Unity engine also introduced Cinematic Image Effects to help make Unity games look less generic. Unity began offering an experimental and unsupported Linux editor build in August 2015. Unity 5.6 added new lighting and particle effects, updated the engine's overall performance, and added native support for Nintendo Switch , Facebook Gameroom, Google Daydream , and

3060-538: The Unity Editor will support Apple Silicon . The first beta version shipped later that year. Unity 2021 brought multiple new features such as Bolt, Unity's Visual Scripting system, a new multiplayer library to support multiplayer games, improved Il2cpp runtime performance, Volumetric clouds for the High Definition Render pipeline. Shadow caching and Screen Space Global Illumination for HDRP. For

3145-946: The Unity engine for a streamlined asset sharing in-game iteration process. Unity 2018 featured the Scriptable Render Pipeline for developers to create high-end graphics. This included the High-Definition Rendering Pipeline for console and PC experiences, and the Lightweight Rendering Pipeline (later renamed to the Universal Render Pipeline) for mobile, virtual reality, and augmented reality. Unity 2018 also included machine learning tools, such as Imitation Learning, whereby games learn from real player habits, support for Magic Leap, and templates for new developers. The C# source code of Unity

3230-501: The Unity game engine in 2013. This featured tools that allowed tracking advertising campaigns and deep linking, where users were directly linked from social media posts to specific portions within games, and easy in-game-image sharing. In 2016, Facebook developed a new PC gaming platform with Unity. Unity provided support for Facebook's gaming platforms, and Unity developers could more quickly export and publish games to Facebook. The Verge said of 2015's Unity 5 release: "Unity started with

3315-614: The Universal Render Pipeline it added new features such as point light shadows, Deferred renderer and general core engine improvements and fixes. Full Apple Silicon support was also added in Unity 2021.2. Unity Hub support for Apple Silicon editors arrived in version 3.0 in January 2022. Changes to Unity 2022 were intended to improve productivity by reducing the time required to enter play mode and import files, and implementing visual search queries and multi selection in

3400-743: The WebGL 2 specification started in 2013 and finished in January 2017. The specification is based on OpenGL ES 3.0. First implementations are in Firefox 51, Chrome 56 and Opera 43. Almost Native Graphics Layer Engine (ANGLE) is an open source graphic engine which implements WebGL 1.0 (2.0 which closely conforms to ES 3.0) and OpenGL ES 2.0 and 3.0 standards. It is a default backend for both Google Chrome and Mozilla Firefox on Windows platforms and works by translating WebGL and OpenGL calls to available platform-specific APIs. ANGLE currently provides access to OpenGL ES 2.0 and 3.0 to desktop OpenGL, OpenGL ES, Direct3D 9, and Direct3D 11 APIs. ″[Google] Chrome uses ANGLE for all graphics rendering on Windows, including

3485-618: The WebGL API as text strings. The WebGL implementation compiles these strings to GPU code. This code is executed for each vertex sent through the API and for each pixel rasterized to the screen. WebGL evolved out of the Canvas 3D experiments started by Vladimir Vukićević at Mozilla . Vukićević first demonstrated a Canvas 3D prototype in 2006. By the end of 2007, both Mozilla and Opera had made their own separate implementations. In early 2009,

3570-558: The WebGL API, which provides little on its own to quickly create desirable 3D graphics, motivated the creation of higher-level libraries that abstract common operations (e.g. loading scene graphs and 3D objects in certain formats; applying linear transformations to shaders or view frustums ). Some such libraries were ported to JavaScript from other languages. Examples of libraries that provide high-level features include A-Frame (VR) , BabylonJS, PlayCanvas , three.js , OSG.JS , Google ’s model-viewer and CopperLicht . Web3D also made

3655-559: The accelerated Canvas2D implementation and the Native Client sandbox environment.″ WebGL is widely supported by modern browsers. However, its availability depends on other factors, too, like whether the GPU supports it. The official WebGL website offers a simple test page. More detailed information (like what renderer the browser uses, and what extensions are available) can be found at third-party websites. The low-level nature of

3740-486: The browser is the platform. Web applications generally employ a client–server model , but vary widely in complexity and functionality. It can be hard to reconcile the desire for features with the need for compatibility. Basic web applications perform all or most processing from a stateless server , and pass the result to the client web browser. All user interaction with the application consists of simple exchanges of data requests and server responses. This type of application

3825-513: The browser, in addition to classic Netscape -style browser plugins. Much of the browser itself is written in XUL, CSS, and JavaScript. There are many tools available to help the process of cross-platform programming: There are many challenges when developing cross-platform software. WebGL WebGL (short for Web Graphics Library ) is a JavaScript API for rendering interactive 2D and 3D graphics within any compatible web browser without

3910-586: The changes were intended to encourage games with large install bases such as Genshin Impact , Subway Surfers and Hearthstone to migrate to Unity services in order to get a fee reduction. The article noted that the Operate Solutions division, handling in-app-purchase services for example, was far more profitable than the Create division, and added that "The many indie developers who will be left by

3995-482: The closed console systems (PlayStation, Nintendo Switch, and Xbox) regardless of revenue to have a Unity Pro license or a Preferred Platform License Key from the manufacturers. Sony and Nintendo provide this as part of the SDK, but Microsoft had yet to implement this functionality for their SDK. The engine source code is licensed on a "per-case basis via special arrangements". On September 12, 2023, Unity announced that use of

4080-449: The code may be stored as separate codebases, or merged into one codebase. An alternative to porting is cross-platform virtualization , where applications compiled for one platform can run on another without modification of the source code or binaries. As an example, Apple's Rosetta , which is built into Intel -based Macintosh computers, runs applications compiled for the previous generation of Macs that used PowerPC CPUs. Another example

4165-470: The code, but can be worthwhile where the amount of platform-specific code is high. This strategy relies on having one codebase that may be compiled to multiple platform-specific formats. One technique is conditional compilation . With this technique, code that is common to all platforms is not repeated. Blocks of code that are only relevant to certain platforms are made conditional, so that they are only interpreted or compiled when needed. Another technique

4250-447: The complexities of client differentiation behind a single, unified API, at the expense of vendor lock-in . Responsive web design (RWD) is a Web design approach aimed at crafting the visual layout of sites to provide an optimal viewing experience—easy reading and navigation with a minimum of resizing, panning, and scrolling—across a wide range of devices, from mobile phones to desktop computer monitors. Little or no platform-specific code

4335-461: The core industry. I think it's sad that most people are consumers of technology and not creators. The world's a better place when people know how to create, not just consume, and that's what we're trying to promote." In December 2016, Unity Technologies announced that they would change the version numbering system for Unity from sequence-based identifiers to year of release to align the versioning with their more frequent release cadence; Unity 5.6

4420-668: The corporation changed to a subscription model. Unity has free and paid licensing options. The free license is for personal use or smaller companies generating less than $ 100,000 annually, later raised to $ 200,000, and the subscriptions are based on revenues generated by the games using Unity. The subscription-based versions also include additional features geared towards professional projects, including analytics, performance analysis and error reporting, and Cloud Build among others. The paid option, Unity Pro, had been required for developers that had over $ 200,000 in annual revenue, but this also could have been provided for console developers through

4505-526: The decision of which platform to use to consumers. The first game to allow this level of interactivity between PC and console games (Dreamcast with specially produced keyboard and mouse) was Quake 3 . Games that feature cross-platform online play include Rocket League , Final Fantasy XIV , Street Fighter V , Killer Instinct , Paragon and Fable Fortune , and Minecraft with its Better Together update on Windows 10 , VR editions, Pocket Edition and Xbox One . Cross-platform programming

4590-718: The digital store. Unity is a cross-platform engine. The Unity editor is supported on Windows , macOS , and the Linux platform, while the engine itself currently supports building games for more than 19 different platforms, including mobile, desktop, consoles, and virtual reality. Unity 2022.3 LTS officially supports the following platforms: Formerly supported platforms are Wii , Wii U , PlayStation 3 , Xbox 360 , Tizen , PlayStation Vita , 3DS , BlackBerry 10 , Windows Phone 8 , Samsung Smart TV , Gear VR , Daydream , Vuforia , Facebook Gameroom, and Stadia . Unity formerly supported other platforms including its own Unity Web Player,

4675-458: The engine for multi-platform games, period." A May 2012 survey by Game Developer magazine indicated Unity as its top game engine for mobile platforms. In November 2012, Unity Technologies delivered Unity 4.0. This version added DirectX 11 and Adobe Flash support, new animation tools called Mecanim, and access to the Linux preview. Facebook integrated a software development kit for games using

4760-448: The engine offers a primary scripting API in C# using Mono , for both the Unity editor in the form of plugins, and games themselves, as well as drag and drop functionality. Prior to C# being the primary programming language used for the engine, it previously supported Boo , which was removed with the release of Unity 5, and a Boo-based implementation of JavaScript called UnityScript , which

4845-546: The engine would become subject to royalties (referred to as a "runtime fee") beginning in January 2024, calculated per-installation and charged monthly, if the product reaches specific revenue and lifetime installation thresholds. Unity states that monetizing the runtime in this manner is required to "allow creators to keep the ongoing financial gains from player engagement ." The new terms faced criticism from game developers who had been using Unity for years, particularly regarding how this fee would be calculated and enforced, and

4930-612: The engine's graphics features for desktop computers and video game consoles. In addition to Android support, Unity 3 featured integration of Illuminate Labs' Beast Lightmap tool, deferred rendering, a built-in tree editor, native font rendering, automatic UV mapping , and audio filters, among other features. In 2012 VentureBeat wrote, "Few companies have contributed as much to the flowing of independently produced games as Unity Technologies. [...] More than 1.3 million developers are using its tools to create gee-whiz graphics in their iOS, Android, console, PC, and web-based games. Unity wants to be

Unity Machine Learning Agents can act as virtual characters or robots to learn creative strategies to interact with simulated real-world environments. The software is used, for example, to develop robots and self-driving cars. In the 2010s, Unity Technologies used its game engine to transition into other industries using

5100-408: The goal of making game development universally accessible. [...] Unity 5 is a long-awaited step towards that future." With Unity 5, the engine improved its lighting and audio. Through WebGL , Unity developers could add their games to compatible Web browsers with no plug-ins required for players. Unity 5.0 offered real-time global illumination, light mapping previews, Unity Cloud, a new audio system, and

5185-497: The implications for demos , freemium games and bundles distributed for charitable causes. The change was considered to be contradictory to statements made by former CEO John Riccitiello in 2015 when Unity originally announced its shift to free and subscription-based models, stating that all users would "get the full power of Unity for free", and that there would not be royalties (in contrast to Unreal Engine , which had recently switched to free distribution but with royalties paid above

Because of the competing interests of compatibility and functionality, numerous design strategies have emerged. Many software systems use a layered architecture where platform-dependent code is restricted to the upper- and lowermost layers. Graceful degradation attempts to provide

5525-411: The new fee, as long as they did not update their project after the January 1, 2024 date. Ars Technica also discovered that Unity had apparently removed a GitHub repository that permitted developers to track changes in Unity's terms of service; Mega Crit accused Unity of having done so to apply their new financial model to games retroactively. An analysis by Game Developer came to the conclusion that

5610-403: The package manager. For 2D projects, changes focused on accelerating core software, import, animation, and physics. Sprite atlasing was revised. Support for PSD extension files and layer management were added to the 2D PSD Importer, and Delaunay tessellation for 2D physics was added. On November 16, 2023, Unity announced that the next version of the engine would be called Unity 6, reverting to

5695-542: The platform they were built for—which means that a single cross-platform executable could be very bloated with code that never executes on a particular platform. Instead, generally there is a selection of executables, each built for one platform. For software that is distributed as a binary executable, such as that written in C or C++, there must be a software build for each platform, using a toolset that translates—transcompiles—a single codebase into multiple binary executables. For example, Firefox , an open-source web browser,

5780-413: The previous $ 100,000 threshold), fees would only apply to games developed with Unity 2024 and beyond without any retroactive fees, and the fee would be based on the lesser of 2.5% of monthly revenue or a calculated value based on monthly engagements, both which rely only on self-reporting of these numbers. Unity Technologies faced a 60% decline in stock price over the year to May 2024, partially attributed to

5865-455: The previous version numbering convention. Unity 6 launched on October 17, 2024, with new features including new generative AI tools called Unity Muse and Unity Sentis. Unity also announced plans for a revised licensing agreement, including a runtime-fee (see #Runtime fee reception ). In response to backlash, Unity canceled this runtime fee in September 2024. Unity gives users the ability to create games and experiences in both 2D and 3D , and

5950-523: The price of existing plans. The engine is used in games including Pokémon Go , Monument Valley , Call of Duty: Mobile , Beat Saber and Cuphead according to the Financial Times in 2020. Some early commercial games in 2007 include Splume (Flashbang Studios), Magical Flying Pink Pony Game (Starscene Software) and Global Conflicts: Palestine (Serious Games Interactive). As of 2018, Unity had been used to create approximately half of

6035-400: The real-time 3D platform, including film and automotive. Unity first experimented in filmmaking with Adam , a short film about a robot escaping from prison. Later, Unity partnered with filmmaker Neill Blomkamp , whose Oats Studios used the engine's tools, including real-time rendering and Cinemachine, to create two computer-generated short films, Adam: The Mirror and Adam: The Prophet .

6120-536: The rendering bottleneck by giving almost direct access to the GPU has exposed performance limitations in the JavaScript implementations. Some were addressed by asm.js and WebAssembly (similarly, the introduction of Stage3D exposed performance problems within ActionScript , which were addressed by projects like CrossBridge ). As with any other graphics API, creating content for WebGL scenes requires using

6205-489: The roadside are completely incidental to Unity's goals, and are not going to be a significant factor in its future decision making." Gameindustry.biz described the move as "self-combustion" and identified the changes as an example of enshittification . In response to this negative feedback, Unity Technologies introduced revised runtime fee terms on September 22, 2023. These included removing any fees for uses of Unity Personal for projects funded up to $ 200,000 (an increase from

6290-473: The runtime fee policy. Usage of Unity waned after these licensing decisions within the indie game community. The use of Unity at the 2023 Global Game Jam was 61%; this declined to 36% for 2024. A similar decline was recorded by the GMTK Game Jam . CEO Matthew Bromberg announced in September 2024 that the company was discontinuing the runtime fee model of licensing, and instead would annually increase

6375-497: The same or similar functionality to all users and platforms, while diminishing that functionality to a least common denominator for more limited client browsers. For example, a user attempting to use a limited-feature browser to access Gmail may notice that Gmail switches to basic mode, with reduced functionality but still of use. Some software is maintained in distinct codebases for different (hardware and OS) platforms, with equivalent functionality. This requires more effort to maintain

6460-447: The type of processor (CPU) or other hardware on which an operating system (OS) or application runs, the type of OS, or a combination of the two. An example of a common platform is Android which runs on the ARM architecture family . Other well-known platforms are Linux / Unix , macOS and Windows , these are all cross-platform. Applications can be written to depend on the features of

6545-587: The use of plug-ins . WebGL is fully integrated with other web standards , allowing GPU -accelerated usage of physics, image processing, and effects in the HTML canvas . WebGL elements can be mixed with other HTML elements and composited with other parts of the page or page background. WebGL programs consist of control code written in JavaScript, and shader code written in OpenGL ES Shading Language (GLSL ES, sometimes referred to as ESSL),

6630-497: The video game to the same standard. To offset this, a video game may be released on a few platforms first, then later on others. Typically, this happens when a new gaming system is released, because video game developers need to acquaint themselves with its hardware and software. Some games may not be cross-platform because of licensing agreements between developers and video game console manufacturers that limit development to one particular console. As an example, Disney could create

6715-480: The world's most lucrative mobile games", such as Pokémon Go and Activision 's Call of Duty Mobile . In June 2020, Unity introduced the Mixed and Augmented Reality Studio (MARS), which provides developers with additional functionality for rules-based generation of augmented reality (AR) applications. Unity released Unity Forma, an automotive and retail solution tool, on December 9, 2020. In June 2020, Unity announced

6800-705: Was deprecated in August 2017, after the release of Unity 2017.1, in favor of C#. Within 2D games, Unity allows importation of sprites and an advanced 2D world renderer. For 3D games, Unity allows specification of texture compression , mipmaps , and resolution settings for each platform that the game engine supports, and provides support for bump mapping , reflection mapping , parallax mapping , screen space ambient occlusion (SSAO), dynamic shadows using shadow maps , render-to-texture and full-screen post-processing effects. Two separate render pipelines are available, High Definition Render Pipeline (HDRP) and Universal Render Pipeline (URP, previously LWRP), in addition to

6885-490: Was published under a "reference-only" license in March 2018, which prohibits reuse and modification. As of 2020, software built with Unity's game engine was running on more than 1.5 billion devices. According to Unity, apps made with their game engine account for 50 percent of all mobile games, and are downloaded more than 3 billion times per month, and approximately 15,000 new projects are started daily with its software. Financial Times reported that Unity's engine "powers some of

6970-769: Was released in early 2014. The character was designed by Unity Technologies Japan designer "ntny" as an open-source heroine character. The company allows the use of Unity-chan and related characters in secondary projects under certain licenses. For example, Unity-chan appears as a playable character in Runbow . Cross-platform For example, a cross-platform application may run on Linux , macOS and Microsoft Windows . Cross-platform software may run on many platforms, or as few as two. Some frameworks for cross-platform development are Codename One , ArkUI-X, Kivy , Qt , GTK , Flutter , NativeScript , Xamarin , Apache Cordova , Ionic , and React Native . Platform can refer to

7055-728: Was shown at Worldwide Developers Conference 2005 by Scott Forstall on Mac OS X . The next year, Unity was named runner-up in the Best Use of Mac OS X Graphics category in Apple Inc. 's Apple Design Awards. Unity was initially released for Mac OS X, later adding support for Microsoft Windows and Web browsers. Unity 2.0 launched in 2007 with approximately 50 new features. DirectX support was added in 2.0. The release included an optimized terrain engine for detailed 3D environments, real-time dynamic shadows, directional lights and spotlights, video playback, and other features. The release also added

7140-565: Was the norm in the early phases of World Wide Web application development. Such applications follow a simple transaction model, identical to that of serving static web pages . Today, they are still relatively common, especially where cross-platform compatibility and simplicity are deemed more critical than advanced functionality. Prominent examples of advanced web applications include the Web interface to Gmail and Google Maps . Such applications routinely depend on additional features found only in

7225-489: Was therefore followed by Unity 2017. Unity 2017 tools featured a real-time graphics rendering engine, color grading and worldbuilding, live operations analytics and performance reporting. Unity 2017.2 underscored Unity Technologies' plans beyond video games. This included new tools such as Timeline, which allowed developers to drag-and-drop animations into games, and Cinemachine, a smart camera system within games. Unity 2017.2 also integrated Autodesk 's 3DS Max and Maya tools into
