The document serves as a guide on Unity, a multi-platform integrated IDE for game development, covering key components such as interface, scripting, scenes, and project assets. It explores game objects, prefabs, graphics, physics, audio, and animations, emphasizing Unity's capabilities for creating and exporting games. The content is aimed at students in a Computer Game Design course, detailing essential tools and features for game development.

• SUMMARY

3. UNITY
• UNITY IS A MULTI-PLATFORM, INTEGRATED IDE FOR SCRIPTING GAMES, AND
WORKING WITH 3D VIRTUAL WORLDS
• INCLUDING:
• GAME ENGINE
3D OBJECTS / LIGHTING / PHYSICS / ANIMATION / SCRIPTING
• ACCOMPANYING SCRIPT EDITOR
MONODEVELOP (WIN/MAC)
CAN ALSO USE VISUAL STUDIO (WINDOWS)
• 3D OBJECT ANIMATION MANAGER
• GUI SYSTEM
• EXECUTABLE EXPORTER MANY PLATFORMS:

4. MAIN INTERFACE COMPONENTS
1. SCENE
• EDITABLE (DESIGN-TIME) 3D GAME OBJECTS IN THE CURRENT SCENE
2. HIERARCHY
• TEXT LIST OF GAME OBJECTS AND SUB-OBJECTS IN THE CURRENT SCENE
3. INSPECTOR
• PROPERTIES FOR CURRENTLY SELECTED
4. GAME
• PREVIEW HOW GAME WILL LOOK WHEN EXECUTING
5. PROJECT
• CONTENTS OF PROJECT ‘ASSETS’ FOLDER (I.E. FILES IN THAT FOLDER)
~LIBRARY OF SCRIPTS, DIGITAL MEDIA FILES, AND SCENES

5. SCRIPTING
• UNITY IMPLEMENTS A MONO COMPILER
• SCRIPTS CAN BE WRITTEN IN:
• JAVASCRIPT
• MOST INTRODUCTORY TUTORIALS ARE WRITTEN IN JAVASCRIPT
• C#
• VERY SIMILAR TO JAVA, UNITY CAN BE INTEGRATED WITH THE MICROSOFT VISUAL
STUDIO EDITOR, TO GET FULL BENEFITS OF CODE COMPLETION, SOURCE VERSION
CONTROL ETC.

6. SCENES
• A UNITY “SCENE” IS ESSENTIALLY A “LEVEL” OR “SCREEN”
• TYPICAL GAME
• WELCOME / MAIN MENU SCREEN
• BUTTONS: PLAY GAME / SEE HIGH SCORES / READ INSTRUCTIONS /
CHANGE INPUT SETTINGS
• LEVEL 1 / LEVEL COMPLETE / LEVEL 2 ETC.
• GAME OVER / ENTER DETAILS FOR NEW HIGH SCORE ETC.

7. PROJECT ASSETS
• THE ASSETS FOLDER FOR EACH UNITY PROJECT CONTAINS:
• SCENES
• MEDIA ASSETS
(IMAGES, SOUNDS FILES, 3D MODELS)
• SCRIPT FILES
• “PACKAGES”
(COLLECTIONS OF UNITY ASSETS, READY TO IMPORT)

8. GAME OBJECTS
• EVERYTHING IN A SCENE IS EITHER A GAME OBJECT OR A
COMPONENT INSIDE A GAME OBJECT
• EVERY GAME OBJECT HAS AT LEAST 1 COMPONENT
• ITS TRANSFORM (AN OBJECT’S POSITION, SCALE, ROTATION)
• OTHER COMPONENTS DEPEND ON OBJECT TYPE (AUDIO, MESH, MATERIAL,
SCRIPT ETC.)
• GAME OBJECTS CAN BE IN A HIERARHCY – SO AN OBJECT CAN BE A
SUB-OBJECT OF ANOTHER OBJECT
• E.G. AN “ARM” OBJECT CAN BE A SUB-OBJECT OF A “BODY” OBJECT ETC.

9. PREFABS
A PREFAB IS A COPY OF A GAME-OBJECT CONVERTED INTO A
REUSABLE ASSET.
• UNITY’S PREFAB SYSTEM ALLOWS USER TO CREATE, CONFIGURE, AND
STORE A GAMEOBJECT COMPLETE WITH ALL ITS COMPONENTS,
PROPERTY VALUES, AND CHILD GAMEOBJECTS
• AT DESIGN TIME (IN EDITOR) A PREFAB CAN BE DRAGGED FROM PROJECT
WINDOW INTO THE SCENE WINDOW AND ADDED THE SCENE’S
HIERARCHY OF GAME OBJECTS
• THE OBJECT CAN THEN BE EDITED
(I.E. CUSTOMIZED FROM THE PREFAB DEFAULT SETTINGS) IF DESIRED.

10. GRAPHICS
• UNITY PROVIDES GRAPHICAL FEATURES SUCH AS:
• RENDERING
• LIGHTENING
• MATERIAL
• SHADES
• TEXTURES
• REFLECTION PROBS
• CLUSTER RENDERING
• AND CAMERA SETTINGS.

11. PHYSICS
• TO PRESENT A SCENE IN CONVINCING BEHAVIOR ITS OBJECTS
MUST BE FOLLOWING RULES OF PHYSICS JUST LIKE ANY OBJECT
MOVEMENT AND COLLISION MUST BE RELATED TO PHYSICS RULES.
• ITS PROVIDE COMPONENTS LIKE:
• GRAVITY
• RIGIDITY OF OBJECT BODY OR COLLISION OF OBJECTS.

12. AUDIO
• UNITY’S AUDIO FEATURES INCLUDES:
• FULL 3D SPATIAL SOUND, REAL-TIME MIXING AND MASTERING, HIERARCHIES
OF MIXERS, SNAPSHOTS, PREDEFINED EFFECTS.
• UNITY’S AUDIO SYSTEM IS FLEXIBLE AND POWERFUL.
• IT CAN IMPORT MOST STANDARD AUDIO FILE FORMATS
• IT HAS SOPHISTICATED FEATURES FOR PLAYING SOUNDS
• IN 3D SPACE, OPTIONALLY WITH EFFECTS LIKE ECHO
AND FILTERING APPLIED.

13. ANIMATIONS
• ANIMATION IS A METHOD IN WHICH FIGURES ARE MANIPULATED TO APPEAR AS
MOVING IMAGES
• UNITY HAS VERY SOPHISTICATED FEATURE IN WHICH DEVELOPER CAN CREATE
ANIMATIONS AS IT PROVIDES ANIMATION WINDOW AND ANIMATOR
CONTROLLER.
• TRANSITIONS CAN BE MADE ON OBJECT WHICH TAKES OBJECT FROM ONE STATE
TO ANOTHER STATE.

14. SUMMARY
• UNITY IS POWERFUL, COMPLETE GAME DEVELOPMENT SYSTEM
• CREATE 3D OBJECTS / SCENES IN UNITY
• OR IMPORT OBJECTS CREATED IN 3D MODELLING PACKAGES
• USE SCRIPTING TO CONTROL ANIMATIONS / SCENE CHANGES ETC.
• EXPORT TO STAND ALONE GAME, OR WEB PAGE COMPONENT, OR MOBILE APP
