   Unity isa 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) << RECOMMENDED TO USE ▪ Unitron (Mac) / UniSciTE (Windows) << DEFAULT ▪ Can also use Visual Studio (Windows)  3D terrain editor  3D object animation manager  GUI system  Executable exporter many platforms: native application / web player / iPhone / Android / Wii 2

  1 – SceneScene = Hierarchy = same, just diff. views  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 exectuting 5 – Project  Contents of Project ‘assets’ folder (i.e. files in that folder) – library of scripts, digital media files, and scenes 4

   Unity implementsa MONO compiler  Scripts can be written in  JavaScript ▪ Note – most introductory tutorials are written in Javascript – for those learning programming its fine  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. ▪ Serious developers work in C# …  Also BOO (like Python) – little development is this … 5

   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 …  All the above would be separate “scenes” in unity  Some scenes may be entirely based around the Unity GUI scripts / components – i.e. be text / buttons on screen 6

   The Assetsfolder for each Unity project contains:  Scenes  Media assets (images, sounds files, 3D models)  Script files  “packages” (collections of unity assets, ready to import)  The contents of the Unity “Project” panel reflect the contents of the “Assets” folder 7

   Everthing ina 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. 8

   Since object-oriented(although this is partially hidden when scripting in JavaScript) instances can be INSTANTIATED at run time  Unity uses the term PREFAB for a pre-fabricated object template (i.e. a class combining 3D objects and scripts)  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. customised from the prefab default settings) if desired  At RUN TIME a script can cause a new object instance to be created (instantiated) at a given location / with a given transform set of properties 9

  • Unity ispowerful, 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 10
