Demo A version of something such as
computer software produced to
demonstrate its capabilities or for
use as a trial:
http://www.oxforddictionaries.co
m/definition/english/demo
A Demo in my opinion is used to
ul timately test your final product
to see how people react and
what your ta rget audience could
be.

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.
ttp://www.urbandictionary.com/defin
e.php?term=Beta
a beta version of a game in my
opinion is the Line between
compl ete and incomplete and
can help pick off those last few
bugs your game may have.
the term BETA a s it i s the BETA of the game ‘Destiny’.
Alpha Thi s phase i s were developers
generally test the software using
white box techniques. Alpha software
can be unstable and cause crashes
and data loss.
http://en.wikipedia.org/wiki/Software
_release_life_cycle#Alpha
The alpha of a game can in my
opinion lead to your final product
as not many people play it due to
the unstable nature of the
vers ion.
the term ALPHA as i t shows Minecraft in it’s Alpha stage.

IG2 Task 1

Pre-Alpha
Pre-alpha refers to all activities
performed during the software
project before testing. Including

beta/
The pre alpha is a development
s tage and does not run as well as
other s tages of game
development such as beta and
the gold master version.
Thi s is relevant of the term PRE-ALPHA as the picture above is of the game World Of War
Craft in i ts PRE-ALPHA VERSION.
Gold A golden master, or GM i s the final
vers ion of a software program that is
sent to manufacturing and is used to
make retail copies.
http://www.techterms.com/definitio
n/goldenmaster
The gold master is the final
vers ion of a game and is the
vers ion the game will be copied
from.

Debug In computers, debugging is the
process of locating and fixing or
bypassing bugs (errors) in computer
program code or the engineering of
hardware device.

tes ting every aspect of i t checking
for bugs and other imperfections.
Thi s shows the classification of white box testing.

(or postproc for
short) is used in the video/film
business for quality-improvement
image
processing (specifically digital
image processing) methods used
in video playback devices, (such
as stand-aloneDVD-Video
players), and video players
software and transcoding software.
It is also commonly used in real-time
3D rendering (such as in
video games) to add additional
effects.

Entity ntity-component-system (ECS) is
a software architecture pattern that
implements concepts
from Composition over
inheritance using a database-like
structure. Common ECS
approaches are highly compatible

Physics A phisics engine is general used
describe a software program
that is used to simulate phisical
phenomena. One of the first
uses of a phisics engine was for
simulating where artillary
shells would land based on
their weight.
http://www.computerhope.co

The physics engine is used to
s imulate physical actions in a
game like a punch or explosion.

Collision collisons consist of
algorrithiams to detect
collision in 2D games depend
on the type of shapes that can
collide.

col l ision of s hape’s in a 2D game.
Thi s image shows collision programming inside a game engine and the radius of it.
Lighting High-dynamic-range rendering (HDRR
or HDR rendering), also known as
high-dynamic-range l ighting, i s the
rendering of computer graphics
s cenes by using lighting calculations
done in a larger dynamic range. This
al lows preservation of details that
may be lost due to limiting contrast
ratios. Video games and computer-generated
movies and special effects
benefit from this as i t creates more
realistic scenes than with the more
s implistic l ighting models used.
Lighting will help t render you
game better and is used to create
more realistic scenes.

AA – Anti-
Aliasing
Anti allising is used to detect
and smooth out jagged edges
using a quick scan.

any images look better with
smoother quality.
Thi s image is showing anti aliasing so the smoothing out of the image in the image.
LoD –
Level of
Detail
The level of detail for a BIM
model must correspond to the
needs of the modeler, the
project engineer, and the
estimators and schedulers.
LOD identifies how much
information is known about a
model element at a given time
http://www.vicosoftware.com/
BIM-Level-of-
Detail/tabid/89638/
The level of design focuses on the
amount of information known on
the level and helps the modeller
des ign the level.
Thi s image shows the Level of detail in the level design involved in the image.

IG2 Task 1

Animation Animation is the process of
displaying still images in a
rapid sequence to create the
illusion of movement. These
images can be hand drawn,
computer generated, or
pictures of 3D objects.
http://www.wisegeek.org/wha
t-is-animation.
htm#didyouknowou
t
Animation is basically used to
make your characters come to
l i fe and can be used to make
characters move and add motion
to the s cene your game is
currently in.
Thi s image is showing the animation used on a character involved in a game.
Sprite A graphic image that can move
within a larger graphic.
Animation software that
supports sprites enables the
designer to develop
independent animated images
that can then be combined in a
larger animation.
http://www.webopedia.com/T
ERM/S/sprite.html
A spri te is something that is used
within a bigger graphic and helps
make developing a game much
easier.
Thi s image shows multiple images used to create an animation

IG2 Task 1

structure commonly used by
vector-based graphics editing
applications and modern
computer games. Examples of

3D, Adobe Illustrator,
AutoCAD, CorelDRAW,
OpenSceneGraph, OpenSG,
VRML97, and X3D.
http://en.wikipedia.org/wiki/S
cene_graph
Scene graphics is generally data
used on modern games and is
edited easily by programs such as
i l lustrator.
Thi s image is showing the structure that is used to create a s cene in a game.
Library If you are creating HTML5 games, i t
makes a lot of sense to start out with
some game engine or framework. The
good news is that there are many free
HTML5 game engines and frameworks
out there, from very minimal to pretty
complex. Below I will cover some of
the mos t popular HTML5 game
frameworks and I will also cover
particle systems, game tutorials,
examples, and demos. To start, I think
i t makes a lot of sense to take a step
back and watch these slides on
HTML5 game development.
Thi s is a framework of all your
data used during the creation of
the game and al components
needed such as weapon designs
and such.

IG2 Task 1

UI User interface design in games
differs from other UI design
because it involves an
additional element -- fiction.
The fiction involves an avatar
of the actual user, or player
http://www.gamasutra.com/bl
ogs/AnthonyStonehouse/2014
0227/211823/User_interface_
design_in_video_games.php
User interface is how a player
plays a game so there own
personal s tyle within a game.
Thi s image is showing the inner working of the level and of the design.
Frames frame or fps determines the
sleakness of a game and how
the game overall looks.
http://gamedev.stackexchange
.com/questions/6825/time-based-
movement-vs-frame-rate-
based-movement
Frames is the amount of frames
you get per second and the
amount of frames you get per
second is determined by the
amount of RAM your computer
has .
Thi s image is showing the average frame for certain times.

IG2 Task 1
14
Concept Bas ically what the idea of the game is. The concept is the base idea of a
game so the idea which turns
into program and then the
modelling then the game.
Thi s is showing some concept art for a game.
Event Decouple when a message or
event is sent from when it is
processed.
An event i s when a program or
character is s et to do things on
command when a certain
mes sage is relayed.
Thi s is programming the character to do certain things at different.
Path
finding
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 Dijkstra's algorithm for
finding the shortest path on
a weighted graph.
The plotting of paths is finding
the quickest possible way
through a puzzle and is used to
set character paths in game.
Thi s shows a path finding algarythm implemented in a game.
