make_map_walls()

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. Must not be NULL, can be "none".
RP	map parameters.

pick_joined_wall()

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.
layout
i
j	where to insert.
RP	map parameters.

Returns

correct wall archetype to fit on the square.

Todo:

check if there isn't an equivalent function in the building code, merge?

retrofit_joined_wall()

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.

If insert_flag is 1, . If not, it will only return the wall which would belong there, and doesn't remove anything. It depends on the global, previously-set variable, "wall_name"

Parameters

the_map
i
j	where to look.
insert_flag	if 1, insert the correct wall into the map, else don't insert.
RP	map parameters.

Returns

correct wall for spot.

Todo:

merge with pick_joined_wall()?

surround_flag()

int surround_flag	(	char **	layout,

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

Parameters

layout
i
j	spot to look.
RP	map parameters.

Returns

combination of:

• 1 = something on left.
• 2 = something on right.
• 4 = something on above.
• 8 = something on below.

Todo:

Parameters

RP	map parameters.

Returns

surround_flag3()

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

map
i
j	spot to look.
RP	map parameters.

Returns

combination of:

• 1 = blocked on left.
• 2 = blocked on right.
• 4 = blocked on above.
• 8 = blocked on below.
