TESTING
Demo “A game demo is a freely distributed piece of an upcoming or recently released
videogame. 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.”
https://en.wikipedia.org/wiki/Game_demo
You wouldcreate one of
these to give people a
glimpse ofa finishedor
nearlyfinishedgame
and helpthem to decide
whether or not they
want to buythe game.
https://en.wikipedia.org/wiki/P.T._(video_game)
Beta ‘”The beta versionof a game is as close to perfect as the company can make it, but any bugs,
glitches or other issues discovered in beta testing will usually be addressed before
the game's official release.”
https://www.techopedia.com/definition/27136/beta-test-gaming
The beta versionis
almost a complete
version ofa game that
mayor maynot be
released to the public
for testingandalso as a
demo.

Alpha “Alpha is the stage when key gameplay functionality is implemented, and assets are partially
finished. A game in alpha is feature complete, that is, game is playable and contains all the
major features. These features may be further revised based on testing and
feedback. Additional small, new features may be added, similarly planned, but unimplemented
features may be dropped. Programmers focus mainly on finishing the codebase, rather than
implementing additions. Alpha occurs eight to ten months before code release, but this can vary
significantly based on the scope of content and assets any given game has.”

Pre-Alpha “A prototype, does not resemble the final version in visual aesthetic or feature set.Probably
demonstrates a core-mechanic that makes the game unique. Could be an experiment you
wanted to try and show a few people (friends, forums, gamejam crowd).”
https://www.reddit.com/r/gamedev/comments/33mp7g/can_we_discuss_the_term_prealpha/
The even more basic
version ofa game where
the earliest versions of
the basic exist.

Gold “In software and application development, a gold version is the final stage of software
development and follows the alpha and beta testing cycles of software development. The gold
version is the final version of the software as it will be released to the public. Most or all
known bugs prior to release are fixed, and all intended functions for final release are
implemented. Media and developers will often use the phrase "gone gold" to announce a
software product's impending release.”
http://www.webopedia.com/TERM/G/gold_version.html
Makingyour game ‘go
gold’ wouldmean
lockingina final release
date for a game. Thisis
usuallyafter a lot of
delays.

White-Box
Testing
“Also known as glass box, structural, clear box and open box testing. A software testing
technique whereby explicit knowledge of the internal workings of the item being tested are
used to select the test data.”
http://www.webopedia.com/TERM/W/White_Box_Testing.html
This is used to test the
software andreport
back withwhat is wrong
if anything.

engineterminology
Bug “A software bug is an error, flaw, failure or fault in a computer program or system that causes it
to produce an incorrect or unexpected result, or to behave in unintended ways. Most bugs arise
from mistakes and errors made by people in either a program's source code or its design, or in
frameworks and operating systems usedby such programs, and a few are caused
by compilers producing incorrect code.”
https://en.wikipedia.org/wiki/Software_bug
A couple of bugs
appeared as a result of
conflicting or incorrect
code.

ENGINES
Vertex
Shader
“The vertex shader is used to transform the attributes of vertices (points of a triangle) such as
color, texture, position and direction from the original color 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
I usedthis to manipulate
objects I createdin a 3D
space.

Post
Processing
“The process of changing the perceivedquality of a video on playback.”
https://en.wikipedia.org/wiki/Video_post-processing
During the loadingof a
game, the qualityof the
game is changed
accordinglyto fit the set
qualitysettings.
http://www.pcgamer.com/pc-graphics-options-explained/
Rendering “Rendering is the process of generating an image from a 2D or 3D model (or models in what
collectively could be called a scene file) by means of computer programs.”
https://en.wikipedia.org/wiki/Rendering_(computer_graphics)
This is used to create a
cleanandfinal version
of an object to be used
within a game.

Normal
Map
“A normal map is an image that stores a direction at each pixel. A normal map is commonly
used to fake high-resolution details on a low-resolution model. Each pixel of the map stores the
surface slope of the original high-res mesh at that point. This creates the illusion of more surface
detail or better curvature. However, the silhouette of the model doesn't change.”
http://wiki.polycount.com/wiki/Normal_map
This is adding a texture
to an object that creates
the illusion ofa high
resolution object.

Entity “The entity is a general purpose object. Usually, it only consists of a unique id. They ‘tag every
coarse gameobject as a separate item’. Implementations typically use a plain integer for this.”
https://en.wikipedia.org/wiki/Entity_component_system
I have these in the forms
of 2D sprites and 3D
objects.

Procedural
Texture
“A procedural texture is a computer-generated image created using an algorithm intended to
create a realistic representation of natural elements such as wood, marble, granite, metal,
stone, and others.”
https://en.wikipedia.org/wiki/Procedural_texture
This is used in order to
easilygive an object the
look you intendit to
have bygivinga realistic
look to it.
https://environmentart.wordpress.com/
Physics “A physics engine is computer software that provides an approximate simulation of
certain physical systems, such as rigid body dynamics (including collision detection), soft body
dynamics, and fluid dynamics, of use in the domains of computer graphics, video
games and film. Their main uses are in video games (typically as middleware), in which case
the simulations are in real-time. The term is sometimes used more generally to describe
any software system for simulating physical phenomena, such as high-performance scientific
simulation.”
https://en.wikipedia.org/wiki/Physics_engine
This would be used to
add gravityand
movement to objects in
order for themto move,

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.”
https://www.techopedia.com/definition/4778/collision-detection
I usedthis for bothmy
2D and 3D game levels
so that the player
character wouldreact to
different objects
appropriately.

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.”
https://www.techopedia.com/definition/11791/level-of-detail-lod
objects blurrier the
further awaytheyare.
This creates depth inside
of the game world.

Animation “Computer animation encompasses a variety of techniques, the unifying factor being that the
animation is created digitally on a computer. 2D animation techniques tend to focus on image
manipulation while 3D techniques usually build virtual worlds in which characters and objects
move and interact. 3D animation can create images that seem real to the viewer.”
https://en.wikipedia.org/wiki/Animation#Computer_animation
I usedthis inorder to
make my2D sprites
appear to move and
interact to different
things.
