A* pathfinding in our game

Because right now our prototype game is building on basic system  which is made by myself, so I try to using the A* pathfinding in Unity to let our dogs can choose the right way, when we send the order. It is so helpful especially you are going to do a RTS game. At first I was wondering about that when some object can destroy on the map and the path will be changed, the A*  pathingfinding can work well or not. It did much better than I thought.

This is the link of the A* pathfinding.
