tag, weight, face, name

$conn->stats_update ($stats)
$conn->container_add ($id, $item...)
$conn->container_clear ($id)
$conn->item_update ($item)
$conn->item_delete ($item...)
$conn->spell_add ($spell)
$spell = {
   tag          => ...,
   level        => ...,
   casting_time => ...,
   mana         => ...,
   grace        => ...,

   face         => ...,
   name         => ...,
   message      => ...,
};
$conn->spell_update ($spell)

(the default implementation calls delete then add)

$conn->spell_delete ($spell)
$conn->magicmap ($w, $h, $px, $py, $data)
$conn->map_change ($type, ...)
$conn->image_info ($numfaces, $chksum, [...image-sets])
$conn->map_change ($mode, ...) [OVERWRITE]
current <flags> <x> <y> <width> <height> <hashstring>
$conn->map_clear [OVERWRITE]

Called whenever the map is to be erased completely.

$conn->map_update ([ [x,y], [x,y], ...]) [OVERWRITE]

Called with a list of x|y coordinate pairs (as arrayrefs) for cells that have been updated and need refreshing.

$conn->map_scroll ($dx, $dy) [OVERWRITE]

Called whenever the map has been scrolled.

$conn->face_update ($facenum, $facedata, $changed) [OVERWRITE]

Called with the face number of face structure whenever a face image becomes known (either because face_find returned it, in which case $changed is false, or because we got an update, in which case $changed is true).

$conn->face_find ($facenum, $facedata) [OVERWRITE]

Find and return the png image for the given face, or the empty list if no face could be found, in which case it will be requested from the server.

$conn->send ($data)

Send a single packet/line to the server.

$conn->send_command ($command[, $cb1[, $cb2]])

Uses either command or ncom to send a user-level command to the server. Encodes the command to UTF-8.

If the server supports a fixed version of the ncom command and this is detected by this module, the following is also supported:

If the callback $cb1 is given, calls it with the absolute time when this command has finished processing, as soon as this information is available.

If the callback $cb2 is given it will be called when the command has finished processing, to the best knowledge of this module :)
