Congrats again on finishing Sushi Neko and building another great iPhone game!
Let's take a look at what you have learned.
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.
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.
