Function Documentation

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.

Here is the caller graph for this function:

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.

void unblock_exits	(	mapstruct *	map,

		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.
