Function Documentation

void make_map_walls	(	mapstruct *	map,
		char **	layout,
		char *	w_style,
		RMParms *	RP
	)

Takes a map and a layout, and puts walls in the map (picked from w_style) at '#' marks.

Parameters:

map	Map where walls will be put.
layout	Layout containing walls and such.
w_style	Wall style.
RP	Random map parameters.

Definition at line 191 of file wall.c.

object* pick_joined_wall	(	object *	the_wall,
		char **	layout,
		int	i,
		int	j,
		RMParms *	RP
	)

Picks the right wall type for this square, to make it look nice, and have everything nicely joined.

It uses the layout.

Parameters:

the_wall	Wall we want to insert.
RP	Random map parameters.

Returns:

Correct wall archetype to fit on the square.

Definition at line 256 of file wall.c.

object* retrofit_joined_wall	(	mapstruct *	the_map,
		int	i,
		int	j,
		int	insert_flag,
		RMParms *	RP
	)

This takes a map, and changes an existing wall to match what's blocked around it, counting only doors and walls as blocked.

Parameters:

insert_flag	If 1, insert the correct wall into the map, otherwise don't insert.
RP	Random map parameters.

Returns:

Correct wall for spot.

Todo:

Merge with pick_joined_wall()?

int surround_flag	(	char **	layout,
		int	i,
		int	j,
		RMParms *	RP
	)

Given a layout and a coordinate, tell me which squares up/down/right/left are occupied.

Parameters:

RP	Random map parameters.

Returns:

Combination of:

• 1: Something on left.
• 2: Something on right.
• 4: Something on above.
• 8: Something on below.

Definition at line 41 of file wall.c.

int surround_flag2	(	char **	layout,
		int	i,
		int	j,
		RMParms *	RP
	)

Given a layout and a coordinate, tell me which squares up/down/right/left are occupied by walls or doors.

Parameters:

RP	Random map parameters.

Returns:

Combination of:

• 1: Wall/door on left.
• 2: Wall/door on right.
• 4: Wall/door on above.
• 8: Wall/door on below.

int surround_flag3	(	mapstruct *	map,
		int	i,
		int	j,
		RMParms *	RP
	)

Check a map for blocked spots.

Since this is part of the random map code, presumption is that this is not a tiled map.

What is considered blocking and not is somewhat hard coded.

Parameters:

RP	Random map parameters.

Returns:

Combination of:

• 1: Blocked on left.
• 2: Blocked on right.
• 4: Blocked on above.
• 8: Blocked on below.

int surround_flag4	(	mapstruct *	map,
		int	i,
		int	j,
		RMParms *	RP
	)

Check a map for spots with walls.

Since this is part of the random map code, presumption is that this is not a tiled map.

What is considered blocking and not is somewhat hard coded.

Parameters:

RP	Random map parameters.

Returns:

Combination of:

• 1: Wall on left.
• 2: Wall on right.
• 4: Wall on above.
• 8: Wall on below.
