Unity is a cross-platform game engine developed by Unity Technologies,[4] first announced and released in June 2005 at Apple Inc.'s Worldwide Developers Conference as an OS X-exclusive game engine. As of 2018, the engine has been extended to support 27 platforms.[5] The engine can be used to create both three-dimensional and two-dimensional games as well as simulations for desktops and laptops, home consoles, smart TVs, and mobile devices. Several major versions of Unity have been released since its launch, with the latest stable version being Unity 2018.2.2, released on August 10, 2018.[6] Unity gives users the ability to create games in both 2D and 3D, and the engine offers a primary scripting API in C#, for both the Unity editor in the form of plugins, and games themselves, as well as drag and drop functionality. Prior to C# being the primary programming language used for the engine, it previously supported Boo, which was removed in the Unity 5[7] release, and a version of JavaScript called UnityScript, which was deprecated in August 2017 after the release of Unity 2017.1 in favor of C#.[8] The engine has support for the following graphics APIs: Direct3D on Windows and Xbox One; OpenGL on Linux, macOS, and Windows; OpenGL ES on Android and iOS; WebGL on the web; and proprietary APIs on the video game consoles. Additionally, Unity supports the low-level APIs Metal on iOS and macOS and Vulkan on Android, Linux, and Windows, as well as Direct3D 12 on Windows and Xbox One.

4. INTRODUCTION TO UNITY
 Unity is Cross-Platform game engine developed by
Unity Technologies.
 Unity is integrated development environment (IDE) for
creating interactive media, typically video games.
 The first version of unity (1.0.0) was developed by
colleagues: David Helgason, Joachim Ante and
Nicholas Francis in Denmark.
 First announced only for OS X, at Apple’s Worldwide
Developers Conference in 2005, its has been
extended to target 21 platforms.

5. WHAT IS UNITY ?
 Game Engine -- To Create 2D and 3d Games.
 Unity is GUI System.
 Unity is 3D Terrain Editor.
 Accompanying Script editor --
Monodevelop (win/mac)
Can also use Visual Studio(Windows)
 3D object animation manager.

6. UNITY BASICS
 Unity is equally suited for to creating 2D and 3D
games.
 When you create a new project in Unity, you have
the choice to start in 2D or 3D mode.
 The choice between starting in 2D or 3D mode
determines some settings for the Unity Editor ,such as
whether images are imported as textures or sprites.

7. 2D OR 3D PROJECTS
Full 3D :-
 3D games usually make use of three-dimensional geometry,
with Materials and Textures.
 3D games usually render the Scene using perspective, so
objects appear larger on screen.

8. Orthographic 3D :-
 Sometimes games use 3D geometry, but use an orthographic
camera instead of perspective.
 Common technique used in games which give you a
bird’s-eye view of the action, and is sometimes called “2.5D”.

9. • Full 2D :-
 Many 2D games use flat graphics, sometimes called
sprites, which have no three-dimensional geometry at all.

10. GRAPHICS
 Are visual images or designs on
some surface.
 Understanding graphics is key to
adding an element of depth to
your game.
 Unity offers amazing visual
fidelity :-
Lighting
Cameras
Materials
Shaders and Textures.

11. PHYSICS
 An object in a game must accelerate
correctly by collisions, gravity and other
forces.
 Unity’s built-in physics engines provide
components that handles the simulation
for you .With just a few parameter
settings.
 Rigid Body is used for object physics.

12. SCRIPTING
 Unity implements a MONO Compiler.
 Scripts can be written in
 JavaScript
 C#
 Beyond that, scripts can be used to
create graphical effects to control the
physical behaviour of objects .
 Even implement a custom AI system
for characters in the game.

13. MULTIPLAYER AND NETWORKING
 Multiplayer Networking is inherently
detailed and complex.
 There are particular issues and
difficulties associated with
synchronizing and communicating .
 Unity’s built-in Multiplayer
Networking and the
associated High Level API (HLAPI).

14. AUDIO
 A game would be incomplete without some kind of audio,
be it background music or sound effects.
 Including an “ Ambisonic Audio”.
 Audio Recording for gaming, Unity can access the
computer’s microphones from a script and create “Audio
Clips” by direct recording.

15. ANIMATION
 In the animation certain objects
should changes their position,
rotation, or other properties over
time.
 Unity’s Animation features
include retarget able animations.
Animation clips from external
sources are created by artists
or animators with 3rd party tools
such as Max or Maya.

16. NAVIGATION
 Allows you to create character
that are intelligent.
 By scene geometry, meshes are
created automatically.
 Navigation support Dynamic
obstacles .

17. ASSETS
 An asset is representation of any
item that can be used in your
game or project.
 Asset Store
 It is home to a growing library
of free and commercial assets.
 Wide variety of assets are there,
For example 3D models,
materials, textures, audio, scripts,
and fonts.

18. PLATFORM
 The platforms are listed as the following:
1. iOS
2. Windows
3. Android
4. PlayStation Etc.

19.  Portability.
 Easy to learn.
 Fast prototyping(no need to recompile everything
to tune values).
Advantages

20. Disadvantages
 Less performance in general than a unreal engine.
 More suited for cross-platform games.
 Managed Programming Languages – Java Script,
C#.
