      • addObstacle

         abstract Unit addObstacle(W obstacle)

        Adds an obstacle to this environment.

        Parameters:
        obstacle - 
        the obstacle to add

      • removeObstacle

         abstract Boolean removeObstacle(W obstacle)

        Removes an obstacle from this environment.

        Parameters:
        obstacle - 
        the obstacle to remove
        Returns:

        true if the obstacle has actually been removed

      • intersectsObstacle

         abstract Boolean intersectsObstacle(P start, P end)

        Checks whether there is at least an obstacle intersecting the line connecting start and end.

        Parameters:
        start - 
        start position
        end - 
        end position
        Returns:

        true if the line connecting start and end touches an obstacle

      • next

         abstract P next(P current, P desired)

        This method must calculate the ABSOLUTE next allowed position given the current position and the position in which the node wants to move. For example, if your node is in position 2,3, wants to move to 3,4 but the next allowed position (because, e.g., of physical obstacles) is 2.5,3.5, the result must be a Position containing coordinates 2.5,3.5.

        Parameters:
        current - 
        the current position
        desired - 
        the desired position
        Returns:

        the next allowed position, where the node can actually move. This position MUST be considered as a vector whose start point is current.

      • getObstacles

         abstract List<W> getObstacles()

        A list of all the obstacles in this environment.
