One of the nice things about Sprite Kit is that it comes with a physics engine right out of the box, which helps in simulating realistic movements and collision detection. If they do not match, those two will not interact. Every bit in every position is '1', so when compared to any other categoryBitMask, Sprite Kit will find a '1' so a collision will occur. There a. If the result is a nonzero value, this body is affected by the collision. We check to see whether either of them was the car and, if true, hide the car in the scene and end the movement of the car and camera. 7. When one body strikes another body, SpriteKit automatically computes the results of the collision and applies impulse to the bodies in the collision. These are my thoughts on #meisenman example for swift 3. 1. However, the genetic algorithm will have 100+ members per population, and each "fight" lasts 10+ seconds.
