Standard Breadth-First Search (BFS) pathfinding using lists (no extra waypoint objects are needed). This allows multiple enemies / allies to find and follow the shortest path to the closest target object (the blue Players in this case)

I could try to further optimize this by implementing a queue using this idea (suggested by grazer; thanks again!)

Features:

-very fast performance (you could actually add this to a game and have it still be playable)

-multiple targets and followers

-moveable / destroyable obstacles, targets, and followers

-dynamic map boundaries (you can go out of bounds and the pathfinding still works)

-simplified code that is easier to modify
