/*
dmm_suite version 1.0
Released January 30th, 2011.
defines the object /dmm_suite
- Provides the proc load_map()
- Loads the specified map file onto the specified z-level.
- provides the proc write_map()
- Returns a text string of the map in dmm format
ready for output to a file.
- provides the proc save_map()
- Returns a .dmm file if map is saved
- Returns FALSE if map fails to save
The dmm_suite provides saving and loading of map files in BYOND's native DMM map
format. It approximates the map saving and loading processes of the Dream Maker
and Dream Seeker programs so as to allow editing, saving, and loading of maps at
runtime.
------------------------
To save a map at runtime, create an instance of /dmm_suite, and then call
write_map(), which accepts three arguments:
- A turf representing one corner of a three dimensional grid (Required).
- Another turf representing the other corner of the same grid (Required).
- Any, or a combination, of several bit flags (Optional, see documentation).
The order in which the turfs are supplied does not matter, the /dmm_writer will
determine the grid containing both, in much the same way as DM's block() function.
write_map() will then return a string representing the saved map in dmm format;
this string can then be saved to a file, or used for any other purose.
------------------------
To load a map at runtime, create an instance of /dmm_suite, and then call load_map(),
which accepts two arguments:
- A .dmm file to load (Required).
- A number representing the z-level on which to start loading the map (Optional).
The /dmm_suite will load the map file starting on the specified z-level. If no
z-level was specified, world.maxz will be increased so as to fit the map. Note
that if you wish to load a map onto a z-level that already has objects on it,
you will have to handle the removal of those objects. Otherwise the new map will
simply load the new objects on top of the old ones.
Also note that all type paths specified in the .dmm file must exist in the world's
code, and that the /dmm_reader trusts that files to be loaded are in fact valid
.dmm files. Errors in the .dmm format will cause runtime errors.
*/
verb/load_map(var/dmm_file as file, var/z_offset as num, var/load_speed as num)
// dmm_file: A .dmm file to load (Required).
// z_offset: A number representing the z-level on which to start loading the map (Optional).
// load_speed: How many tiles should be loaded per second, defaults to no pause (Optional)

SwapMaps library by Lummox JR
developed for digitalBYOND
http://www.digitalbyond.org
Version 2.1
The purpose of this library is to make it easy for authors to swap maps
in and out of their game using savefiles. Swapped-out maps can be
transferred between worlds for an MMORPG, sent to the client, etc.
This is facilitated by the use of a special datum and a global list.
Uses of swapmaps:
- Temporary battle arenas
- House interiors
- Individual custom player houses
- Virtually unlimited terrain
- Sharing maps between servers running different instances of the same
game
- Loading and saving pieces of maps for reusable room templates
*/
/*
User Interface:
VARS:
swapmaps_iconcache
An associative list of icon files with names, like
'player.dmi' = "player"
swapmaps_mode
This must be set at runtime, like in world/New().
SWAPMAPS_SAV 0 (default)
Uses .sav files for raw /savefile output.
SWAPMAPS_TEXT 1
Uses .txt files via ExportText() and ImportText(). These maps
are easily editable and appear to take up less space in the
current version of BYOND.
PROCS:
SwapMaps_Find(id)
Find a map by its id
SwapMaps_Load(id)
Load a map by its id
SwapMaps_Save(id)
Save a map by its id (calls swapmap.Save())
SwapMaps_Unload(id)
Save and unload a map by its id (calls swapmap.Unload())
SwapMaps_Save_All()
Save all maps
SwapMaps_DeleteFile(id)
Delete a map file
SwapMaps_CreateFromTemplate(id)
Create a new map by loading another map to use as a template.
This map has id==src and will not be saved. To make it savable,
change id with swapmap.SetID(newid).
SwapMaps_LoadChunk(id,turf/locorner)
Load a swapmap as a "chunk", at a specific place. A new datum is
created but it's not added to the list of maps to save or unload.
The new datum can be safely deleted without affecting the turfs
it loaded. The purpose of this is to load a map file onto part of
another swapmap or an existing part of the world.
locorner is the corner turf with the lowest x,y,z values.
SwapMaps_SaveChunk(id,turf/corner1,turf/corner2)
Save a piece of the world as a "chunk". A new datum is created
for the chunk, but it can be deleted without destroying any turfs.
The chunk file can be reloaded as a swapmap all its own, or loaded
via SwapMaps_LoadChunk() to become part of another map.
SwapMaps_GetSize(id)
Return a list corresponding to the x,y,z sizes of a map file,
without loading the map.
Returns null if the map is not found.
SwapMaps_AddIconToCache(name,icon)
Cache an icon file by name for space-saving storage
swapmap.New(id,x,y,z)
Create a new map; specify id, width (x), height (y), and
depth (z)
Default size is world.maxx,world.maxy,1
swapmap.New(id,turf1,turf2)
Create a new map; specify id and 2 corners
This becomes a /swapmap for one of the compiled-in maps, for
easy saving.
swapmap.New()
Create a new map datum, but does not allocate space or assign an
ID (used for loading).
swapmap.Del()
Deletes a map but does not save
swapmap.Save()
Saves to map_[id].sav
Maps with id==src are not saved.
swapmap.Unload()
Saves the map and then deletes it
Maps with id==src are not saved.
swapmap.SetID(id)
Change the map's id and make changes to the lookup list
swapmap.AllTurfs(z)
Returns a block of turfs encompassing the entire map, or on just
one z-level
z is in world coordinates; it is optional
swapmap.Contains(turf/T)
Returns nonzero if T is inside the map's boundaries.
Also works for objs and mobs, but the proc is not area-safe.
swapmap.InUse()
Returns nonzero if a mob with a key is within the map's
boundaries.
swapmap.LoCorner(z=z1)
Returns locate(x1,y1,z), where z=z1 if none is specified.
swapmap.HiCorner(z=z2)
Returns locate(x2,y2,z), where z=z2 if none is specified.
swapmap.BuildFilledRectangle(turf/corner1,turf/corner2,item)
Builds a filled rectangle of item from one corner turf to the
other, on multiple z-levels if necessary. The corners may be
specified in any order.
item is a type path like /turf/wall or /obj/barrel{full=1}.
swapmap.BuildRectangle(turf/corner1,turf/corner2,item)
Builds an unfilled rectangle of item from one corner turf to
the other, on multiple z-levels if necessary.
swapmap.BuildInTurfs(list/turfs,item)
Builds item on all of the turfs listed. The list need not
contain only turfs, or even only atoms.
