The Flow Field Pathfinder Plugin comes with a c++ based Blueprint with built in functions for easy to use pathfinding. The Flow Field Blueprint can be easily customized to your needs by changing its deafult parameters. It also has the option to detect obstacles, align itself to the ground and detect slopes that are too steep.
The Plugin also comes with an Ai pawn, a Flow Field Ai component and a Player Controller. These 3 are available to showcase how the Flow Field system can be used.
