How do Pathfinding Algorithms Work?

In the full video, I go over a new feature: the Fish Transporter. This NPC automatically collects and sells fish from your auto fishers, even while you're offline. I also explain how offline earnings are calculated, how the upgrade system works, and how I implemented A* pathfinding to help the transporter move between points on the map. There’s also some discussion around optimization and fixing FPS drops related to invalid movement paths.
