-
-Lets a game entity influence the pathing costs on the (static) pathfinding grid.
-
-This ability should only be used for game entitie that never (or rarely) change positions as pathfinding grid recalculations are expensive. For dynamic pathfinding effects, using the `Collision` ability should be preferred.
-
-**hitbox**
-Hitbox around the game entity that affects the underlying pathfinding grids. All grid cells that are covered by this hitbox ae influenced by the cost definitions in the `path_costs` attribute.
-
-**path_costs**
-Costs of traversing the area defined by the `hitbox` attribute on the pathfinding grid.
-
-Keys are `PathType` objects that are associated with a pathfinding grid in the pathfinder.
-
-Values represent the pathing cost for the terrain on the pathfinding grid. Each value must be an integer between `1` and `255`. `1` defines the *minimum* possible cost and `254` represents the *maximum* possible cost. `255` signifies that the terrain is impassable for the specified path type.
