Demo A vers ion of something such as
computer software produced to
demonstrate i ts capabilities or for
use as a trial.
http://www.oxforddictionaries.com
/definition/english/demo
A demo is an uncompleted
vers ion of a game that i s
generally released to the public
so that they can play the game
and see what i t is like. Almost like
i t i s given potential buyers
knowledge on the game before
they make the final decision to
buy the game.
A good game that I have
knowledge with is Five Nights At
Fre ddy’s. This is a point and click
horror game that uses
animatronics, sounds and jump
s cares to build tension. It gives
you two of the nights in the
demo that you can play to see i f
you l ike the game.

Beta A beta version of a program, game
etc... i s an unfinished version
released to either the public a
select few or whoever signs up to
beta test i t for bugs or glitches.
http://www.urbandictionary.com/d
efine.php?term=Beta
A beta version of a game is
generally used to find out any
bugs and kinks in a game so that
they can release it. The beta of a
game is usually open to the
public to play to test the game
out, as the more people playing
the game, the greater the chance
of finding any bugs that are in a
game. A good example would be
the Battlefield 4 beta that was
released so that people could
both play the game, and look for
game breaking bugs.
h?v=84Zk03cl Ias
Thi s is relevant as i t is showing a game that is in an open beta, showing i t is l etting anyone
try i t out.
Alpha The alpha of a game is the phase in
which they begin to test software
us ing white-box techniques. Alpha
software can be unstable so is
rarely released, but when it i s, i t is
sent almost always purely as raw
source code.
http://en.wikipedia.org/wiki/Softw
are_release_life_cycle
A game that i s in i ts alpha s tages
i s usually a game that s elect
people can play as it is normally
always undergoing testing to find
anything wrong with the game.

Pre-Alpha A development status given to a
program or application that is
usually not feature complete, and is
not usually released to the public.
Developers are usually s till deciding
on what features the program
should have at this status.
http://www.abbreviations.com/pre
-alpha%20version
A pre-alpha game i s a game that
i s not even completely
developed, or even thought up
yet. Thi s version of the game is
rarely ever released to the public
but when it is, i t is so that the
developers of the game can get
some ideas of what they can
implement by the community.
h?v=aJrZkNVwNTs
Thi s shows a game that is in a pre-alpha that has gameplay footage, which shows that
people are allowed to try i t out.
Gold A golden master, or GM, i s the final
vers ion of a software program that
i s sent to manufacturing and is
used to make retail copies of the
software.
http://www.techterms.com/definiti
on/goldenmaster
A game that has gone gold is
usually a game that is sent to be
made, it is the final copy.
h?v=Wt3LIl8JJTg

Debug In computers, to debug is to carry
out the process of locating and
fixing or bypassing bugs (errors) in
computer program code or the
engineering of a hardware device.
http://searchsoftwarequality.techt
arget.com/definition/debugging
When a game i s being debugged,
i t i s the state in which they are
actually removing the bugs from
a game, or i f a game has a debug
menu.
h?v=qwoi26Eh24E
Thi s is relevant as i t is showing a game that has been put in debug mode.
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.
http://en.wikipedia.org/wiki/Test_a
utomation
Automation i s where different
means are used to test a game.
Thi s is relevant as i t is showing a test automation circle.

IG2 Task 1
5
White-Box
Testing
A software testing technique
whereby explicit knowledge of the
internal workings of the item being
tes ted are used to select the test
data . Unlike black box testing,
white box testing uses specific
knowledge of programming code to
examine outputs.
http://www.webopedia.com/TERM
/W/White_Box_Testing.html
White-box testing i s where i t is
being tested with extensive
knowledge of the internal code
that makes up the game. This is
so someone who knows it all can
go through the code and
highlight any flaws in the game.
Thi s shows the steps involved in white box testing.
Bug An error in a structured system. It is
usually applied to electrical and
computer systems.
http://www.urbandictionary.com/d
efine.php?term=Glitch
A bug, or more commonly
known, a glitch, is something
wrong in a s tructured system.
Lots of bugs in games can be
relatively funny, and harmless to
the gaming experience, though
there can be some bugs that are
game breaking, such as bugs that
caus e all of a players progress to
be lost. This can be extremely
annoying and crippling if it i s in a
game such as World of Warcraft,
or GTA V.
h?v=9YFVdgP2Dv4
Thi s shows a glitch in a game, otherwise known as a bug.

http://en.wikipedia.org/wiki/Norm
al_mapping
Normal mapping is where you
map things and uses bumps to
s imulate lighting effects.
Thi s picture shows s tages of mapping, including normal mapping.
Entity Enti ty Sys tems offer an approach to
object design that fits well with
games, where requirements and
behaviours need to be tweaked or
swapped out constantly.
http://shaun.boyblack.co.za/blog/2

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
obs erver.
http://en.wikipedia.org/wiki/Game
_phys ics
Phys ics in a game are where they
try to get i t as close to l ife as
pos sible by bringing real l ife
phys ics into a game. So a crumbly
bui lding crumbling, Water
trickl ing down rocks, cars
crushing into heaps of metal if
they fall from the sky.
h?v=f4nI2zutksM
Thi s shows the game engine incorporating physics.
Collision Col l ision detection typically refers
to the computational problem of
detecting the intersection of two or
more objects. While the topic i s
mos t often associated with i ts use
in video games and other physical
s imulations, it also has applications
in robotics.
http://en.wikipedia.org/wiki/Collisi
on_detection
Col l ision in games is where things
actually collide. This makes a
game more realistic as if there is
water pouring from the sealing,
you would expect that, i f you
placed something under i t, it
would hit the object and change
i ts path, rather than just going
through the object.
h?v=NGh-Vh_NYO0
Col l ision in a game. This shows the collision boxes.

Lighting Bloom (sometimes referred to as
l ight bloom or glow) i s a computer
graphics effect used in video
games, demos and high dynamic
range rendering (HDR) to
reproduce an imaging artifact of
real -world cameras. The effect
produces fringes (or feathers) of
l ight extending from the borders of
bright areas in an image,
contributing to the illusion of an
extremely bright light
overwhelming the camera or eye
capturing the s cene.
http://en.wikipedia.org/wiki/Bloom
_(shader_effect)
Lighting in a game can be used to
bui ld atmosphere i f i t is a horror
game, or just to light up a place.
Mos t people would think that the
l ighting should be realistic,
instead of a tiny light i lluminating
an entire room like it had no
cei ling.
h?v=9LgsEezzrgo
Thi s diagram shows the lighting used by a game engine.
AA – Anti-
Aliasing
In computer graphics, antialiasing is
a software technique for
diminishing jaggies - s tairstep-like
l ines that should be smooth.
http://www.webopedia.com/TERM
/A/antialiasing.html
Anti -Aliasing is where, in a game,
i t i s used so that edges of things
look smoother when they are
more zoomed in. This also makes
i t look better normally.
h?v=RGoBzoHDrj0
Thi s shows the difference on a before/after shot of zooming in on hair.

IG2 Task 1

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.
http://www.techopedia.com/defini
tion/11791/level-of-detail-lod
Level of detail in a game i s how
much detail i s in an object, the
more detail, usually, the better i t
wi l l look, the les s deta i l , the
bigger the polygons .
h?v=XaivEr7_RJs
Thi s is showing differences in the level of detail.
Animation A way of making a movi e by using a
series of drawings, computer
graphics, or photographs of objects
(such as puppets or models) that
are s lightly different from one
another.

Library The Unreal engine (or Source, or
Quake) is designed to be used for
FPS games (it could feasibly be used
for other games, but you'd spend
some time working against the
engine). Ogre3d (or even Directx,
SDL, or other common libraries) can
be used to make any type of game,
without having to rip out major
parts of the code, or work around
them.
http://gamedev.s tackexchange.co
m/questions/10770/whats-the-di
fference-between-a-library-and-an-
engine
A l ibrary in a game holds all of
the s tuff of the game that you
need.
Thi s shows a game engine library.
UI The us er interface, in the industrial
des ign field of human–machine
interaction, i s the space where
interactions between humans and
machines occur. The goal of this
interaction i s effective operation
and control of the machine on the
user's end, and feedback from the
machine, which aids the operator in
making operational decisions.
http://en.wikipedia.org/wiki/User_i
nterface
The UI in a game i s basically the
user interface. Tis allows
whoever is using i t to see what
they are doing.

Event A Game Event (will just call them
Events ) i s anything of interest that
happens while a Game is running.
An explosion going off, the player
being sighted by an enemy, an i tem
being picked up – this are all
events. Games often need some
way to noti fy interested Game
Enti ties when an event occurs and
al so make it possible for those
enti ties to react to events of their
interest in various ways. When this
happens, we can say that a Game
Enti ty i s handling an event. The way
a Game Entity handles and reacts
to di fferent events becomes a
crucial aspect of that Entity
behaviour.
https ://nicolasgoles.com/blog/201
0/12/game-event-handling-part-1/
An event i s something that
triggers things in a game, l ike a
proximity mine needs to be on an
event, or i f something i s triggered
to happen when you walk past i t.
Thi s diagram shows the events in a game engine.
Pathfinding Pathfinding or pathing is the
plotting, by a computer application,
of the shortest route between two
points. It is a more practical variant
on solving mazes. This field of
research is based heavily on
Di jkstra's algorithm for finding the
shortest path on a weighted graph.
http://en.wikipedia.org/wiki/Pathfi
nding
Pathfinding in a game is used
mainly for enemies so that if the
enemies are looking for you, they
can pathfind around the objects
that might be in the way.
Thi s picture shows pathfinding.
