Aappleby's deep dive into A* pathfinding is like opening a treasure chest of game dev secrets, from using hierarchical graphs for smooth sailing across different game scales to dropping 'breadcrumbs' for dynamic path adjustments. YesBox builds on that, painting a picture of their city builder's intricate street and building pathing system, showing us how every bit (or 16-bit bitmask) counts in game design. And gkedzierski? They're soaking up these nuggets of wisdom and already dreaming up video dev logs to spread the word. It's like a masterclass in making virtual worlds come alive!
