This purpose of this post is to document some of the frustrations with pathfinding. I’m finding that it is too boring to try to implement every map at once, so I’m touching pathfinding every other week or so. As a refresher, the video below has served as my primer on GKObstacleGraph whenever I need to revisit pathfinding. So, if you’re a SpriteKit / GameplayKit user, you may find my approach interesting.
