Invisible Wall
An invisible wall (or alpha wall) is a boundary in a video game that limits where a player character can go in a certain area, but does not appear as a physical obstacle. The term can also refer to an obstacle that in reality could easily be bypassed, such as a mid-sized rock or short fence, which does not allow the character to jump over it within the context of the game. In 2D games, the edge of the screen itself can form an invisible wall, since a player character may be prevented from traveling off the edge of the screen. In 3D games, invisible walls are used similarly to prevent a player leaving the gameplay area, or getting trapped in a small inescapable space, though visible boundaries such as stone walls or fences are generally preferred. Completely invisible walls are cited to be level design bugs, and might be "left-over geometry" from an earlier version of the level or an object's improperly-aligned collision box. Nevertheless, designers might add invisible walls o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Blog
A vlog (), also known as a video blog or video log, is a form of blog for which the medium is video. Vlog entries often combine embedded video (or a video link) with supporting text, images, and other metadata. Entries can be recorded in one take or cut into multiple parts. In recent years, "vlogging" has spawned a large community on social media, becoming one of the most popular forms of digital entertainment. It is popularly believed that, alongside being entertaining, vlogs can deliver deep context through imagery as opposed to written blogs. Video logs (vlogs) also often take advantage of web syndication to allow for distribution of the video over the Internet, using either the RSS or Atom syndication formats, for automatic aggregation and playback on mobile devices and personal computers (see video podcast). The vlog category is popular on the video-sharing platform YouTube. History In the 1980s, New York artist Nelson Sullivan documented his experiences travelling ...

Collision Box
Collision detection is the computational problem of detecting an intersection of two or more objects in virtual space. More precisely, it deals with the questions of ''if'', ''when'' and ''where'' two or more objects intersect. Collision detection is a classic problem of computational geometry with applications in computer graphics, physical simulation, video games, robotics (including autonomous driving) and computational physics. Collision detection algorithms can be divided into operating on 2D or 3D spatial objects. Overview Collision detection is closely linked to calculating the distance between objects, as two objects (or more) intersect when the distance between them reaches zero or even becomes negative. Negative distance indicates that one object has penetrated another. Performing collision detection requires more context than just the distance between the objects. Accurately identifying the points of contact on both objects' surfaces is also essential for the comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cheating In Video Games
Cheating in video games involves a video game player using various methods to create an advantage beyond normal gameplay, usually in order to make the game easier. Cheats may be activated from within the game itself (a cheat code implemented by the original game developers), or created by third-party software (a game trainer or debugger) or hardware (a cheat cartridge). They can also be realized by exploiting software bugs. History The first cheat codes were put in place for play testing purposes. Playtesters had to rigorously test the mechanics of a game and introduced cheat codes to make this process easier. An early cheat code can be found in ''Manic Miner'', where typing "6031769" (based on Matthew Smith's driving license) enables the cheat mode. Within months of '' Wizardry: Proving Grounds of the Mad Overlord''s 1981 release, at least two commercial trainers appeared. 1983 advertisements for "The Great Escape Utility" for ''Castle Wolfenstein'' (1981) promised that th ...

Computer Glitch
A glitch is a short-lived technical fault, such as a transient one that corrects itself, making it difficult to troubleshoot. The term is particularly common in the computing and electronics industries, in circuit bending, as well as among players of video games. More generally, all types of systems including human organizations and nature experience glitches. A glitch, which is slight and often temporary, differs from a more serious bug which is a genuine functionality-breaking problem. Alex Pieschel, writing for ''Arcade Review'', said: bug' is often cast as the weightier and more blameworthy pejorative, while 'glitch' suggests something more mysterious and unknowable inflicted by surprise inputs or stuff outside the realm of code". The word itself is sometimes humorously described as being short for "gremlins lurking in the computer hardware". Etymology Some reference books, including ''Random House's American Slang'', state that the term comes from the German word as ...

Playground Of Destruction
A playground, playpark, or play area is a place designed to provide an environment for children that facilitates play, typically outdoors. While a playground is usually designed for children, some are designed for other age groups, or people with disabilities. A playground might exclude children below (or above) a certain age. Modern playgrounds often have recreational equipment such as the seesaw, merry-go-round, swingset, slide, jungle gym, chin-up bars, sandbox, spring rider, trapeze rings, playhouses, and mazes, many of which help children develop physical coordination, strength, and flexibility, as well as providing recreation and enjoyment and supporting social and emotional development. Common in modern playgrounds are ''play structures'' that link many different pieces of equipment. Playgrounds often also have facilities for playing informal games of adult sports, such as a baseball diamond, a skating arena, a basketball court, or a tether ball. Public playground equ ...

Airstrike
An airstrike, air strike, or air raid is an offensive operation carried out by aircraft. Air strikes are delivered from aircraft such as blimps, balloons, fighter aircraft, attack aircraft, bombers, attack helicopters, and drones. The official definition includes all sorts of targets, including enemy air targets, but in popular usage the term is usually narrowed to a tactical (small-scale) attack on a ground or naval objective as opposed to a larger, more general attack such as carpet bombing. Weapons used in an airstrike can range from direct-fire aircraft-mounted cannons and machine guns, rockets and air-to-surface missiles, to various types of aerial bombs, glide bombs, cruise missiles, ballistic missiles, and even directed-energy weapons such as laser weapons. In close air support, air strikes are usually controlled by trained observers on the ground for coordination with ground troops and intelligence in a manner derived from artillery tactics.

Open World
In video games, an open world is a virtual world in which the Gamer, player can approach objectives freely, as opposed to a world with more linear and structured gameplay. Notable games in this category include ''The Legend of Zelda (video game), The Legend of Zelda'' (1986), ''Grand Theft Auto V'' (2013), ''Red Dead Redemption 2'' (2018) and ''Minecraft'' (2011). Games with open or free-roaming worlds typically lack level structures like walls and locked doors, or the invisible walls in more open areas that prevent the player from venturing beyond them; only at the bounds of an open-world game will players be limited by geographic features like vast oceans or impassable mountains. Players typically do not encounter loading screens common in linear level designs when moving about the game world, with the open-world game using strategic storage and memory techniques to load the game world dynamically and seamlessly. Open-world games still enforce many restrictions in the game env ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Level (video Games)
In Video game, video games, a level (also referred to as a map, mission, stage, course, or round in some older games) is any space available to the player during the course of completion of an objective. Video game levels generally have progressively increasing difficulty to appeal to players with different skill levels. Each level may present new concepts and challenges to keep a player's interest high to play for a long time. In games with linear progression, levels are areas of a larger world, such as Green Hill Zone. Games may also feature interconnected levels, representing locations. Although the challenge in a game is often to defeat some sort of character, levels are sometimes designed with a movement challenge, such as a jumping puzzle, a form of obstacle course. Players must judge the distance between platforms or ledges and safely jump between them to reach the next area. These puzzles can slow the momentum down for players of fast action games; the first ''Half-Life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Software Bug
A software bug is a design defect ( bug) in computer software. A computer program with many or serious bugs may be described as ''buggy''. The effects of a software bug range from minor (such as a misspelled word in the user interface) to severe (such as frequent crashing). In 2002, a study commissioned by the US Department of Commerce's National Institute of Standards and Technology concluded that "software bugs, or errors, are so prevalent and so detrimental that they cost the US economy an estimated $59 billion annually, or about 0.6 percent of the gross domestic product". Since the 1950s, some computer systems have been designed to detect or auto-correct various software errors during operations. History Terminology ''Mistake metamorphism'' (from Greek ''meta'' = "change", ''morph'' = "form") refers to the evolution of a defect in the final stage of software deployment. Transformation of a ''mistake'' committed by an analyst in the early stages of the softw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
