DEFINITION OF SWIFT ²  Swift is a new programming language

for iOS, OS X, watchOS and tvOS apps

²  It builds on the best of previous programming languages

²  Swift adopts safe programming patterns and adds modern features to make programming easier, more flexible and more fun

²  With Xcode 7, Apple has made game development more accessible to anyone wanting to learn it

2D GAME DEVELOPMENT (1) ²  SpriteKit is a 2D game development framework for both

iOS and OS X ²  It provides all the tools required to create a complete 2D

game ²  It can create MainMenu, Gameplay , and Options Screens ²  In the gameplay screen, players, enemies, text to display

the score, and particles such as smoke and explosion can be added

²  Some classes in SpriteKit are the basic building blocks for creating any game

2D GAME DEVELOPMENT (2) There are a lot of features in SpriteKit : ²  Graphics technologies:

² Physics simulations technologies:

² Tools and improvements:

ª  Shaders ª  Lighting and shadows

ª  Per-pixel physics ª  Physics fields ª  Inverse kinematics ª  Constraints

ª  SpriteKit Editor ª  Integration with SceneKit

3D GAME DEVELOPMENT (1) ²  SceneKit is a 3D game development framework for

iOS and OS X

²  It is a high-level API built on OpenGL and OpenGL ES, and can be integrated with SpriteKit

²  The camera, lights, and objects for the scene should

be provided ²  Predefined objects can be added, such as boxes,

spheres, tori, planes and texture

²  COLLADA files or Alembic files created in a 3D program can also be imported

²  3D text and shapes can be added also

3D GAME DEVELOPMENT (2) ²  SceneKit provides different light

types such as Ambient, Omni, Direction, and Spot light

²  An editor is available to view your

scene and all the objects added to the scene

²  SceneKit has actions that can be performed on objects to animate them

²  It has a physics engine for physics simulations and collision detection

²  To make the game more lively and the characters a little more believable, animation is required

²  Sprite Sheets Concept is used to optimize the game’s performance

²  A sprite sheet contains all the images that will be used in the game in a single file

²  A particle system is a collection of sprites or particles

²  Each particle system has an emitter from where the particles will be created

²  SpriteKit has an inbuilt particle designer ²  It also includes a number of default particle

systems that are already included

²  Adding background music and sound effects in

SpriteKit is very easy: one-line code is needed ²  It allows the use of the .caf audio file format

and .mp3 files

²  .mp3 files are used more because are smaller in size compared to .caf files (475 kBytes vs. 5.2 Mbytes)

²  The more added audio files, the more it will add to the bundle size

AUDIO & PARALLAX EFFECTS


COMPANY NAME next

²  Parallax or scrolling background is a very

popular effect in games

²  The objects in the foreground will move faster than the objects in the background, which will move much slower

²  It gives the illusion of depth and motion

²  These effects can be implemented in a separate class in the SpriteKit
