  The SlippyFlippy Challenge: Working With Sprite Kit Collision Detection

  

  In our last installment, we ran into a problem trying to get collisions to work correctly with the obstacle. We want it to interact with the penguin, but not the game world. If we  turn on physics, either the edgeLoop on the scene  blocks the obstacle from entering the scene by , or causes very jittery […]

  The Slippy Flippy Dare: How to Use Basic Physics in Sprite Kit

  In the last installment of this series I showed two kinds of animation: SKAction and using the update: method from frame animation. The third major type of animation is using the physics engine. A physics engine takes the mathematical laws of physics and adds them to the scene. It removes the developer from the math […]
