List Of Open Source Games
This is a list of notable open-source video games. Open-source video games are assembled from and are themselves open-source software, including public domain games with public domain source code. This list also includes games in which the engine is open-source but other data (such as art and music) is under a more restrictive license. Open engine and free data The games in this table are developed under a free and open-source license with free content which allows reuse, modification and commercial redistribution of the whole game. Licenses can be public domain, GPL, BSD, Creative Commons, zlib, MIT, Artistic License or other (see the comparison of Free and open-source software and the Comparison of free and open-source software licenses). Open-source games with non-free data (or not entirely free data) Only the game engines in this table are developed under an open-source license, which means that the reuse and modification of only the code is permitted. As some of the games ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNU General Public License
The GNU General Public Licenses (GNU GPL or simply GPL) are a series of widely used free software licenses, or ''copyleft'' licenses, that guarantee end users the freedom to run, study, share, or modify the software. The GPL was the first copyleft license available for general use. It was originally written by Richard Stallman, the founder of the Free Software Foundation (FSF), for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. The licenses in the GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. The GPL is more restrictive than the GNU Lesser General Public License, and even more distinct from the more widely used permissive software licenses such as BSD, MIT, and Apache. Historically, the GPL license family has been one of the most popular software licenses in the free and open-source software (FOSS) domai ...

Online Text-based Role-playing Game
An online text-based role playing game is a role-playing game played online using a solely text-based interface. Online text-based role playing games date to 1978, with the creation of '' MUD1'', which began the MUD heritage that culminates in today's MMORPGs.Sloane, Sarah (2000) ''Digital Fictions: Storytelling in a Material World'', Ablex Publishing Corporation, , p. 168Slator, Brian M. et al "From Dungeons to Classrooms: The Evolution of MUDs as Learning Environments", in Jain, Lakhmi C., Tedman, Raymond A. & Tedman, Debra K.

The store listing has since been restored and the game is available for purchase. Gameplay The game begins with the player awakening in a cold, dark room after a mysterious event. Initially, the player can only light and tend a fire in the room. As the game progresses, the player gains the abilities to collect resources, interact with strangers, start a village, and explore the world. As the game progresses, the type and quantity of resources and exploration a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HTML
Hypertext Markup Language (HTML) is the standard markup language for documents designed to be displayed in a web browser. It defines the content and structure of web content. It is often assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript, a programming language. Web browsers receive HTML documents from a web server or from local storage and browser engine, render the documents into multimedia web pages. HTML describes the structure of a web page Semantic Web, semantically and originally included cues for its appearance. HTML elements are the building blocks of HTML pages. With HTML constructs, HTML element#Images and objects, images and other objects such as Fieldset, interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, Hyperlink, links, quotes, and other items. HTML elements are delineated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruby (programming Language)
Ruby is a general-purpose programming language. It was designed with an emphasis on programming productivity and simplicity. In Ruby, everything is an object (computer science), object, including primitive data types. It was developed in the mid-1990s by Yukihiro Matsumoto, Yukihiro "Matz" Matsumoto in Japan. Ruby is interpreted language, interpreted, high-level programming language, high-level, and Dynamic typing, dynamically typed; its interpreter uses garbage collection (computer science), garbage collection and just-in-time compilation. It supports multiple programming paradigms, including procedural programming, procedural, object-oriented programming, object-oriented, and functional programming. According to the creator, Ruby was influenced by Perl, Smalltalk, Eiffel (programming language), Eiffel, Ada (programming language), Ada, BASIC, and Lisp (programming language), Lisp. History Early concept According to Matsumoto, Ruby was conceived in 1993. In a 1999 post to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sliding Block Puzzle
A sliding puzzle, sliding block puzzle, or sliding tile puzzle is a combination puzzle that challenges a player to slide (frequently flat) pieces along certain routes (usually on a board) to establish a certain end-configuration. The pieces to be moved may consist of simple shapes, or they may be imprinted with colours, patterns, sections of a larger picture (like a jigsaw puzzle), numbers, or letters. Sliding puzzles are essentially two-dimensional in nature, even if the sliding is facilitated by mechanically interlinked pieces (like partially encaged marbles) or three-dimensional tokens. In manufactured wood and plastic products, the linking and encaging is often achieved in combination, through mortise-and-tenon key channels along the edges of the pieces. In at least one vintage case of the popular Chinese cognate game Huarong Road, a wire screen prevents lifting of the pieces, which remain loose. As the illustration shows, some sliding puzzles are mechanical puzzles. How ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2D Computer Graphics
2D computer graphics is the computer-based generation of digital images—mostly from two-dimensional models (such as 2D geometric models, text, and digital images) and by techniques specific to them. It may refer to the branch of computer science that comprises such techniques or to the models themselves. 2D computer graphics are mainly used in applications that were originally developed upon traditional printing and drawing technologies, such as typography, cartography, technical drawing, advertising, etc. In those applications, the two-dimensional image is not just a representation of a real-world object, but an independent artifact with added semantic value; two-dimensional models are therefore preferred, because they give more direct control of the image than 3D computer graphics (whose approach is more akin to photography than to typography). In many domains, such as desktop publishing, engineering, and business, a description of a document based on 2D computer graph ...

MIT License
The MIT License is a permissive software license originating at the Massachusetts Institute of Technology (MIT) in the late 1980s. As a permissive license, it puts very few restrictions on reuse and therefore has high license compatibility. Unlike copyleft software licenses, the MIT License also permits reuse within proprietary software, provided that all copies of the software or its substantial portions include a copy of the terms of the MIT License and also a copyright notice. In 2015, the MIT License was the most popular software license on GitHub, and was still the most popular in 2025. Notable projects that use the MIT License include the X Window System, Ruby on Rails, Node.js, Lua (programming language), Lua, jQuery, .NET, Angular (web framework), Angular, and React (JavaScript library), React. License terms The MIT License has the identifier MIT in the SPDX License List. It is also known as the "#Ambiguity and variants, Expat License". It has the following terms: Co ...

Puzzle Video Game
Puzzle video games make up a broad genre of video games that emphasize puzzle solving. The types of puzzles can test problem-solving skills, including logic, pattern recognition, Sequence, sequence solving, Spatial ability, spatial recognition, and word completion. Many puzzle games involve a real-time element and require quick thinking, such as ''Tetris'' (1985) and ''Lemmings (video game), Lemmings'' (1991). History Puzzle video games owe their origins to brain teasers and puzzles throughout human history. The mathematical strategy game Nim, and other traditional thinking games such as Hangman (game), Hangman and Bulls and Cows (commercialized as ''Mastermind (board game), Mastermind''), were popular targets for computer implementation. In Universal Entertainment's ''Space Panic'', released in arcades in 1980, the player digs holes in platforms to trap creatures. It is a precursor to puzzle-platform games such as ''Lode Runner'' (1983), ''Door Door'' (1983), and ''Doki Dok ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2048 (video Game)
''2048'' is a single-player sliding puzzle, sliding tile puzzle video game written by Italian web developer Gabriele Cirulli and published on GitHub. The objective of the game is to slide numbered tiles on a grid to combine them to create a tile with the number 2048; however, one can continue to play the game after reaching the goal, creating tiles with larger numbers. It was originally written in JavaScript and CSS over a weekend, and released on 9 March 2014 as free and open-source software subject to the MIT License. Versions for iOS and Android (operating system), Android followed in May 2014. ''2048'' was intended to be an improved version of two other games, both of which were clones of the iOS game ''Threes'' released a month earlier. Cirulli himself described ''2048'' as being "conceptually similar" to ''Threes''. The release of ''2048'' resulted in the rapid appearance of many similar games, akin to the flood of ''Flappy Bird'' variations from 2013. The game received gen ...

OpenGL Shading Language
OpenGL Shading Language (GLSL) is a high-level shading language with a syntax based on the C programming language. It was created by the OpenGL ARB (OpenGL Architecture Review Board) to give developers more direct control of the graphics pipeline without having to use ARB assembly language or hardware-specific languages. Background With advances in graphics cards, new features have been added to allow for increased flexibility in the rendering pipeline at the vertex and fragment level. Programmability at this level is achieved with the use of fragment and vertex shaders. Originally, this functionality was achieved by writing shaders in ARB assembly language – a complex and unintuitive task. The OpenGL ARB created the OpenGL Shading Language to provide a more intuitive method for programming the graphics processing unit while maintaining the open standards advantage that has driven OpenGL throughout its history. Originally introduced as an extension to OpenGL 1.4, GLSL w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
