The flood fill approach to path finding is one of the easiest to learn, works great in games with small maps, and is also commonly used in software – filling a picture with color, for example. In this article I’ll walk you through how the algorithm works, and help you build a visual representation of it in action.

The A* algorithm for path finding is not the perfect way to find an optimal route between two nodes in a graph, but it is either the best or darned close most of the time and that makes it a fantastic one to learn for both games and apps alike.

If you watch a flock of birds you’ll see it exhibits all sorts of complex behaviors as they swarm around in the air – they often stay together but not too close, they move in the same direction but also seem to change direction at the same time. In this article we will create flocking behavior in SwiftUI, using Craig Reynolds’ classic boids algorithm.
