Function Documentation

int calculatedmg	(	int	n,
		int	m,
		int	l
	)

int comparecell	(	struct cell	c1,
		struct cell	c2
	)

Compares two cells.

Returns:

1 if cells is equal, 0 otherwise

int createstairs	(	struct cell *	level,
		int	size,
		int	direction
	)

struct directions findfree	(	int	x,
		int	y,
		struct cell *	level,
		struct cell *	cells,
		int	num,
		int	scale
	)			[read]

Finds free (available to step onto) directions for specified spot.

Warning: this is low-level function. Try do not use it somewhere in step.c

Parameters:

	(x,y)	- Coordinates of spot
	level	- See above
	cells	- Container of cells considered non-free to pass through
	scale	- See above

Returns:

struct directions. Value of directions considered free is non-zero, zero othewise

int isclean	(	struct cell *	level,
		int	x,
		int	y,
		int	x2,
		int	y2,
		int	scale
	)

int isempty	(	struct cell *	level,
		int	x,
		int	y,
		int	x2,
		int	y2,
		int	scale
	)

float len	(	int	x,
		int	y,
		int	x2,
		int	y2
	)

Distance between 2 points.

Returns:

sqrt((x2-x)^2+(y2-y)^2). Just a formula from school

int numof_free_states	(	int	x,
		int	y,
		struct cell *	level,
		int	scale
	)

Number of free cells around specified spot.

Parameters:

	(x,y)	- Coordinates
	level	- Container of cells
	scale	- Number of columns in the field of the game
