* Updated/revised description of instance-related script commands (bugreport:4880).
- Fixed 'instance_create' would return -4 (party already instancing) when the requested party was not found. - 'instance_create' return value -2 now means 'party not found' rather than 'missing parameter'. git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@14809 54d463be-8e91-2dee-dedb-b68131a5f0ec

+ * Updated/revised description of instance-related script commands (bugreport:4880). [Ai4rei]
+ - Fixed 'instance_create' would return -4 (party already instancing) when the requested party was not found.
+ - 'instance_create' return value -2 now means 'party not found' rather than 'missing parameter'.
2011/05/01
* Removed functions 'decode_zip' (ancient) and 'encode_zip' (from r824) from grfio. These were outdated copies of zlib's 'uncompress' and 'compress' respectively (related r1530 and r5152). [Ai4rei]
* Removed auto-add feature from mapindex code, as map indexes are used for save data, thus need to be constant across server starts (since r4726). [Ai4rei]

-Destroys instance with the ID <Instance ID>.
+Destroys instance with the ID <instance id>. If no ID is specified, the instance,
+the script is attached to, is used. If the script is not attached to an instance,
+the instance of the currently attached player's party is used. If no player is

---------------------------------------
-*instance_attachmap(<Instance ID>,"<Map Name>")
-*instance_detachmap(<Instance ID>,"<Map Name>")
+*instance_attachmap("<map name>",<instance id>{,<use base name>});
+
+Attaches the map "<map name>" to the instance specified with <instance id>. The
+optional parameter specifies, whether a map requires emulation for instancing (1)
+or not (0 = default).
-Attach or detach the map "<Map Name>" to the instance with the <Instance ID>.
+Returns the resulting map name on success or an empty string on failure.
---------------------------------------
-*instance_init(<Instance ID>);
+*instance_detachmap "<map name>"{,<instance id>};
-Initiate the instance of <Instance ID>.
+Detach the map "<map name>" to the instance with the <instance id>. If no ID is

-*instance_announce <Instance ID>,"<text>",<flag>{,<color>};
+*instance_init <instance id>;
-Works like announce, but has the <Instance ID> parameter, where 0 = active instance?
+Initializes the instance given by <instance id>. This copies all NPCs from the
+source maps to the instanced maps.
---------------------------------------
-*instance_attach(<Instance ID>);
+*instance_announce <instance id>,"<text>",<flag>{,<fontColor>{,<fontType>{,<fontSize>{,<fontAlign>{,<fontY>}}}}};
-Attaches a script to the provided <Instance ID>?
+Works like announce, but has the <instance id> parameter. If instance id is 0, the
+instance, the script is attached to, is used. If the script is not attached to an
+instance, the instance of the currently attached player's party is used. If no

-*instance_npcname("<NPC Name>",<Instance ID>)
+*instance_attach <instance id>;
-Retrieve the unique name given to a copy of an NPC for an instance, the given
-"<NPC Name>" that belongs to instance <Instance ID>. Can be used with such commands
-as enablenpc and disablenpc, donpcevent, etc.
+Attaches the current script to the instance given by <instance id>.
---------------------------------------
-*has_instance("<Map Name>")
+*instance_npcname("<npc name>"{,<instance id>});
-Check if the player has been queued for the <Map Name> instance.
+Retrieves the unique name given to a copy of an NPC given by "<npc name>" in an
+instance specified <instance id>. If no ID is specified, the instance, the script
+is attached to, is used. If the script is not attached to an instance, the
+instance of the currently attached player's party is used. If no player is
+currently attached, the command fails and causes the script to halt.
---------------------------------------
-*instance_id(<?>)
+*has_instance("<map name>"{,<instance id>});
+
+Checks whether or not the given map belongs to specified instance. If no ID is
+specified, the instance, the script is attached to, is used. If the script is not
+attached to an instance, the instance of the currently attached player's party
+is used. If no player is currently attached, the command fails and causes the

-Apparently returns the ID the player is currently attached too.
+Returns the name of the instanced map on success, otherwise an empty string.
---------------------------------------
-*instance_warpall "<Map Name>",<x>,<y>;
+*instance_id({<type>});
-Warp all players in the instance to <map name> and given coordinates.
+Retrieves the instance id, depending on <type>. If type is not given, it defaults
+to 0.
+
+Type:
+ 0 - Instance ID the script is attached to.
+ 1 - Instance ID of the currently attached player's party.

-*instance_set_timeout <Time1>,<Time2>,<Instance ID>;
+*instance_warpall "<map name>",<x>,<y>{,<instance id>};
+
+Warps all players in the instance <instance id> to <map name> at given
+coordinates. If no ID is specified, the instance, the script is attached to,
+is used. If the script is not attached to an instance, the instance of the
+currently attached player's party is used. If no player is currently attached,
+the command fails and causes the script to halt.
+
+---------------------------------------
+
+*instance_set_timeout <alive timeout>,<idle timeout>{,<instance id>};
+
+Sets the timeout values for an instance given by <instance id>. If no ID is
+specified, the instance, the script is attached to, is used. If the script is
+not attached to an instance, the instance of the currently attached player's
+party is used. If no player is currently attached, the command fails and causes
+the script to halt.
-Lifetime of <Time1> for <Instance ID>, while <Time2> is how long until the
-instance times out while inactive.
+Parameter <alive timeout> specifies the total amount of time the instance will
+exist. Parameter <idle timeout> specifies how long players have, when they are
+outside of the instance, until it is destroyed.
