Function Documentation

unsigned int bestroute	(	unsigned int *	doorsRow,
		unsigned int *	doorsCol,
		unsigned int	numOfDoor,
		unsigned int *	doorId
	)

Function that calculate the best route from the start point and each door of the schema, and selects the shortest of theese.

It uses an algorithm that analize the boxes iteratively, evalueting each box (step of the route), looking for the cheaper neighbour in a estabilished order ( LEFT - DOWN - RIGHT - UP ).

Returns:

Best route value (unsigned int).

Parameters:

	doorsRow	Number of row of the doors
	doorsCol	Number of column of the doors
	numOfDoor	Number of doors
	doorId	Nearest door to the start point
