Sliding when controlling an actor by controller

Normally, in 3d games, when actors are trying to run against the wall, it’s easy to get sliding vectors because collision information contains normal vector.
The game that I’m developing is 2d game, and we bought this astarpath solution for pathfinding, and I wonder if there is suitable APIs in this solution to get such sliding vectors when using GridGraph.

Hi

Unfortunately there is no such API. Grid graphs would also be very bad at giving relevant collision information since they are quite jagged. Often people complement pathfinding with physics when developing games.
