VIDEO GAMES / VIDEO GAME TESTING

Demo “A game demo is a freely distributed piece of an upcoming or recently released video game. Demos are typically released by the game's publisher to help consumers get a feel of the game before deciding whether to buy the full version.”

http://en.wikipedia.org/wiki/Game_demo

A demo is a small piece of a finished game that is made available to the public so they can try the game.

In my own production practice, I would use a demo to show off parts of the finished game, so people who like the look of the game could try it.

Beta A beta is software still under development that is made available to a select few to test, examine, and report problems they face. Beta testing allows developers to find problems they may have missed and fix them before the program is released.

Often there are two beta testing phases, open beta and closed beta. An open beta also known as a public beta refers to beta testing that is open to any user, who is known as a beta tester. Closed beta refers to beta testing that is only available to a select few individuals or

A beta is the stage in a game’s life cycle where it is nearing completion, and about to be finished.

In my own production practice, during the beta phase, I would start making sure that everything is finalised, and any last bugs will be worked out of the code.

Screenshot of Battlefield: Hardline beta footage.Alpha A very early version of a software

product that may not contain all of the features that are planned for the final version. Typically, software goes through two stages of testing before it is considered finished. The first stage, called alpha testing, is often performed only by users within the organization developing the software.

http://www.webopedia.com/TERM/A/alpha_version.html

An alpha is the stage around about in the middle of a game’s life cycle, where more assets are being added.

In my own production practice, I would make sure that, during the alpha stage, I would add more visual appeal, and start to add more features to gameplay.

https://www.youtube.com/watch?v=9MiMjQwd2VE

Pre-Alpha Pre-Alpha is a standard term to denote a number of interim milestones between prototyping and alpha, each of which includes new functionality and/or game content. Pre-alphas often mandate incremented improvements on a number

A pre-alpha is around about the start of a game’s life cycle, everything looks pretty rough, but the basic idea is there.

In my own production practice,

of parallel areas in a project, but rarely expect any one of those areas to be complete. The exact content of each pre-alpha is often an ongoing discussion between producers on the team and those at the publisher.

Pre-alphas are usually followed by alpha, beta, release candidate and gold master milestones.

http://www.whatgamesare.com/pre-alpha.html

I would make sure that idea and concept works before adding any visual effects or tweaking the level design.

Gold A game has "Gone Gold" when the final master copy has been produced at the developer and sent off for replication, packaging and shipment. The game is not yet released, but it will typically be around 2-3 weeks (sometimes less) before it begins appearing on store shelves and online pre-orders arriving at doorsteps. The term itself comes from the old practice of recordable CDs being manufactured with gold film. Hence the gold coloured CD actually being the source, with no reference to copies sold as in the recording industry.

http://www.urbandictionary.com/define.php?term=Gone%20Gold

When a game is gold, it is almost finished, any last minute bugs are being fixed, no changes to visuals should happen.

In my own production practice, I would make sure that at the gold stage, my game is completely finished. I may push updates out after the game’s release if there are any serious bugs left in the game, but I should aim to completely leave the game alone at this point.

stage.Debug In computers, debugging is the process of

locating and fixing or bypassing bugs (errors) in computer program code or the engineering of a hardware device. To debug a program or hardware device is to start with a problem, isolate the source of the problem, and then fix it.

http://searchsoftwarequality.techtarget.com/

definition/debugging

A debug is where developers try to get rid of bugs in the game to fix anything that shouldn’t happen.

In my own production practice, it would be important to keep debugging my game so the game works and doesn’t break during gameplay.

Image showing the Debug menu of the game ‘Super Mario 64’Automation In software testing, test automation is

the use of special software (separate from the software being tested) to control the execution of tests and the comparison of actual outcomes with predicted outcomes. Test automation can automate some repetitive but necessary tasks in a formalized testing process already in place, or add additional testing that would be difficult to perform manually.

http://en.wikipedia.org/wiki/

Automation is a type of testing that is mainly left to run by itself.

In my own production practice, it would be important to use automation to test the game and keep it bug free.

White-box testing is a methodology used to ensure and validate the internal framework, mechanisms, objects and components of a software application. White-box testing verifies code according to design specifications and uncovers application vulnerabilities.

http://www.techopedia.com/definition/3891/white-box-testing

In my own production practice, it would be important to use white-box testing in the same way it would be important to use automation, so bugs can be worked out of the code before the game goes gold.

program to crash or produce invalid output. The problem is caused by insufficient or erroneous logic. A bug can be an error, mistake, defect or fault, which may cause failure or deviation from expected results.

http://www.techopedia.com/definition/24864/software-bug-

A bug is a glitch in the code of the game, bugs will generally cause gameplay to act irregularly or crash the game.

In my own production practice, it would be important to get all of the bugs out of the game’s code, so the gameplay doesn’t crash or behave incorrectly.

GAME ENGINES

Vertex Shader

A programmable function in display adapters that offers a graphics application programmer flexibility in rendering an image. The vertex shader is used to transform the attributes of vertices (points of a triangle) such as colour, texture, position and direction from the original colour space to the display space. It allows the original objects to be distorted or reshaped in any manner.

http://www.pcmag.com/encyclopedia/term/53754/vertex-shader

A vertex shader allows for 3D models to be changed however is needed to change the look of the model.

In my own production practice, I would use a Vertex Shader to change the look of 3D models to suit the game accordingly.

materials and surfaces that mimic reality. An infinite number of material effects replace the artificial, computerized look with high-impact organic surfaces. Characters now have facial hair and blemishes, golf balls have dimples, a red chair gains a subtle leather look, and wood exhibits texture and grain. By altering the lighting and surface effects, artists are able to manipulate colours, textures, or shapes and to generate complex, realistic scenes.

http://www.nvidia.co.uk/object/feature_pixelshader.html

A pixel shader changes the look of the textures in the game to make them look more realistic and life-like.

In my own production practice, I would use a pixel shader to create more detail on 3D models and environments, so they look much more realistic.

Post Processing

Post processing allows different effects to be performed on the scene after it has been rendered, but before outputting it to the viewport… Examples of elements and effects include bloom (HDR blooming effect on bright objects), depth of field, motion blur, ambient occlusion, and material effects, which are custom materials run on the final scene image.

http://udn.epicgames.com/Three/PostProcessEffectsHome.html

Post Processing effects allow the game to look a certain way after completion of models and environments.

In my own production practice, it would be important to use post processing effects to make the game look a certain way after the game had been rendered.

Video from the developers of Overgrowth explaining what post processing effects do.

Rendering The term rendering refers to the calculations performed by a 3D software package’s render engine to translate the scene from a mathematical approximation to a finalized 2D image. During the process, the entire scene’s spatial, textural, and lighting information are combined to determine the colour value of each pixel in the flattened image.

http://3d.about.com/od/3d-101-The-Basics/a/Rendering-Finalizing-The-3d-Image.htm

Rendering is the process that allows a 3D image to be turned into a 2D image to be shown on screen.

In my own production practice, it would be important to use rendering to create a 3D image on screen

Salford City CollegeEccles Sixth Form CentreBTEC Extended Diploma in GAMES DESIGNUnit 73: Sound For Computer GamesIG2 Task 1

Map the same purpose: they simulate the impression of a detailed 3D surface, by modifying the shading as if the surface had lots of small angles, rather than being completely flat. Because it's just modifying the shading of each pixel, this will not cast any shadows and will not obstruct other objects.

[Normal maps] are images that store a direction, the direction of normals directly in the RGB values of an image. They are much more accurate, as rather than only simulating the pixel being away from the face along a line, they can simulate that pixel being moved at any direction, in an arbitrary way.

http://wiki.blender.org/index.php/Doc:2.4/Manual/Textures/Influence/Material/

Bump_and_Normal

allows more detail to be applied to a 3D model without using large amounts of triangles.

In my own production practice, I would use a normal map to add more details onto a 3D model, so processing power could be saved.

Entity Entity: A unique ID that tags each game-object as a separate item.

http://entity-systems.wikidot.com/

An entity is an object within a game that can be interacted with.

In my own production practice, I would use entities to separate between interactive items and items that are merely there for show and cannot be interacted with.

http://blog.playcanvas.com/wp-content/uploads/2014/06/Entity-context.jpg

Image of an entity being edited.UV Map UV mapping is the 3D modeling process

of making a 2D image representation of a 3D model's surface.

http://en.wikipedia.org/wiki/UV_mapping

A UV map is a flattened out 3D model, which is then easier to texture without distortion.

In my own production practice, I would use a UV map so I could put textures onto 3D models correctly, without the textures distorting.

Image detailing what a UV Map looks like on and off a 3D model.Procedural Texture

Procedural textures take an entirely different approach. Instead of creating an image by defining a large, unchanging block of pixels, procedurals create the texture from the ground up. This is where the term 'procedural' comes from. The texture is defined only by the procedure needed to create it. You only need to give the computer a (relatively) small formula, instead of a huge block of pixels. With this formula, the computer is able to create the texture at any scale, in any orientation, extending as far as you need.

http://www.upvector.com/?section=Tutorials&subsection=Intro%20to

%20Procedural%20Textures

A procedural texture is a texture that changes with the model, and can be resized or changed in any way.

In my own production practice, I would use procedural textures for texturing large models without having the texture stretch.

Physics Computer animation physics or game physics involves the introduction of the laws of physics into a simulation or game engine, particularly in 3D computer graphics, for the purpose of making the effects appear more real to the observer. Typically, simulation physics is only a close approximation to real physics, and computation is performed using discrete values.

There are several elements that form components of simulation physics including the physics engine, program code that is used to simulate Newtonian physics within the environment, and

Physics make movement and the way objects interact with the player in a game more realistic

In my own production practice, I would use physics so objects would move and react realistically within the world.

Collision Collision detection algorithmically calculates impact time by identifying two or more object intersection points. Collision detection is also a virtual interface that determines user and object distance for collision prevention. Collision detection is a key 3-D component associated with robotics, video games and physical simulation.

http://www.techopedia.com/definition/4778/collision-detection

Collision is the calculation that detects when two entities touch each other.

In my own production practice, I would use collision detection to detect whenever two entities collide with one another. Depending on the entity, it may take damage from the collision.

important in any type of game. From Myst-like puzzles to real time strategy to first person shooters, lighting plays a huge role in how players interact with a game’s world are impacted by it. Mysterious and horror games meant to keep players on the edge of their seats usually have darker environments, punctuated by brighter areas and objects

Lighting is the process that lights up the environment of a game to add atmosphere to the game.

In my own production practice, I would use lighting to add atmosphere to my game by lighting certain areas in certain colours.

to ensure you notice them. Other genres tend to use more balanced lighting systems, and games that are praised for their appearance masterfully paint their worlds onto our screens, the environments telling stories of their own. Lighting is a topic which merits an in-depth study all on its own; most artists spend years mastering the subtleties of light and color. This article will introduce you to the key concepts of light in computer graphics and how to use it effectively.

AA – Anti-Aliasing

Antialiasing is a technique for softening or blurring sharp edges so they appear less jagged when rendered.Antialiasing is accomplished by multisampling each pixel at multiple pixel locations and combining the samples to generate a final pixel colour. Increasing the number of samples per pixel increases the amount of antialiasing which generates a smoother edge. 4x multisampling requires four samples per pixel and 2x multisampling requires two samples per pixel.

http://msdn.microsoft.com/en-us/library/bb976069.aspx

AA makes the lines between objects in a game look less jagged and more smooth.

In my own production practice, I would use AA to make the lines of my 3D models smoother and more lifelike

LoD – Level of Detail

Level of detail is a general design term for video game landscapes in which closer objects are rendered with more polygons than objects that are farther away. Generally speaking, the level of detail is dictated by the game's system requirements. Given the power of modern processors, very little degradation in the level of detail is noticeable anymore.

Level of detail renders objects differently at different distances to save on processing power.

In my own production practice, I would use LOD to render objects at certain distances, so objects wouldn’t have to be high quality all the time, so I could decrease the amount of

displaying a series of pictures, or frames. Cartoons on television is one example of animation. Animation on computers is one of the chief ingredients of multimedia presentations. There are many software applications that enable you to create animations that you can display on a computer monitor.

http://www.webopedia.com/TERM/A/animation.html

Animation is the way the game moves about, whether it be 2D or 3D.

Concept The first stage of designing a game is coming up with a concept. This is the idea you will base your design and development activity around. Picture your game and try to give it a category: is it a platformer, an adventure game, or a shooter?

https://www.udemy.com/blog/designing-games/

A concept is the initial idea of a game, which can then be developed into the full thing.

In my own production practice, I would come up with the concept for my game before anything else, as that is what I would be basing gameplay and visuals from.

programming is a programming paradigm in which the flow of the program is determined by events such as user actions (mouse clicks, key presses), sensor outputs, or messages from other programs/threads. Event-driven programming is the dominant paradigm used in graphical user interfaces and other applications (e.g. JavaScript web applications) that are centred around performing certain actions in response to user input.
