Project: Learn to clone Timberman with SpriteKit and Swift 3

Congrats again on finishing Sushi Neko and building another great iPhone game!

Let's take a look at what you have learned.

The game

Core game objects

  • Subclassing: Subclassing SKSpriteNode to create custom game object classes, to implement specific functionality.

  • Enumeration: Using enumeration to facilitate game object state tracking.

  • Property Observation: Using didSet property observation to monitor property changes and apply relevant changes such as changing character position or modifying scale.

  • Multi part object: Creating more complex game objects out of multiple sprites.

The Sushi Tower

  • Dynamic Tower: Learn to utilize a RNG and apply rules to dynamically generate sushi object to fill the sushi tower block.

Core Mechanic

  • Game state management: Managing the game state through the game lifecycle from first play to death and back again.

  • User Interface: Adding a basic user interface for the player.

  • Collision detection: Learning how to build alternative code based collision detection, no need for physics collision detection here.

  • Array management: Managing an array, adding new pieces to the top of the array and removing the first piece in the array.

Turning a mechanic into a game

  • Health & Score: Adding health and score mechanics, using game counters and using property observation to reflect these counters visually.
