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

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

18. COMPANY NAME
next
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

19. COMPANY NAME

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
