Function Documentation

find_in_layout()

void find_in_layout	(	int	mode,
		char	target,
		int *	fx,
		int *	fy,
		char **	layout,
		RMParms *	RP
	)

Find a character in the layout.

Parameters

mode	how to look: 1: from top/left to bottom/right. 2: from top/right to bottom/left. 3: from bottom/left to top/right. 4: from bottom/right to top/left. other value: one random order is chosen.
target	character to search.
fx
fy	position of character, or -1 if not found.
layout	maze.
RP	maze parameters.

place_exits()

void place_exits	(	mapstruct *	map,
		char **	maze,
		char *	exitstyle,
		int	orientation,
		RMParms *	RP
	)

Place exits in the map.

Parameters

map	map to put exits into.
maze	map layout.
exitstyle	what style to use. If NULL uses a random one.
orientation	how exits should be oriented: 0 means random. 1 means descending dungeon. 2 means ascending dungeon. 3 means rightward. 4 means leftward. 5 means northward. 6 means southward.
RP	map parameters.

Note

unblock_exits() should be called at some point, as exits will be blocking everything to avoid putting other objects on them.

Todo:

add orientations 3-6 or fix previous comment.

unblock_exits()

void unblock_exits	(	mapstruct *	map,
		char **	maze,
		RMParms *	RP
	)

This function unblocks the exits. We blocked them to keep things from being dumped on them during the other phases of random map generation.

Parameters

map	map to alter.
maze	map layout.
RP	map generation parameters.
