SkFun: SpriteKit And RubyMotion
summary
Shows how to build a Flappy Bird clone using SpriteKit + RubyMotion, using one SKView that swaps SKScene instances, SKNode/SKSpriteNode for characters, reusable SKTexture to cut memory, and SKAction sequences with repeatActionForever for parallax (two-image scrolling). Explains the game loop hooks (update, didEvaluateActions, didSimulatePhysics), physics bodies (dynamic/static/edge), contact vs collision with 32-category bitmasks, aims for 60 FPS, and adds GameController support for up to four controllers.
