Description

Inventory checkers passively check the players inventory for a specific object. You can set a connected value that is triggered either if that object is present or missing (-> "last_sp") when a player walks over the inventory checker. A valid option is to remove the matching object (usually not recommended, see "last_heal").

Alternatively, you can set your inventory checker to block all players that do/don't carry the matching object (-> "blocked movement").

As you can see, inventory checkers are quite powerful, holding a great variety of possibilities.

Attributes

Attribute	Field	Description
block view	FLAG_BLOCKSVIEW	If an item is set to block view, players (and monsters) cannot see beyond it unless they cross it or manage to stand on top.
blocked movement	obj::move_block	If set, only players meeting the match criteria can pass through that space. If unset (default), the inventory checker acts like a trigger/button.
connection	connection value	Whenever the inventory checker is triggered, all objects with identical <connection> value get activated. This only makes sense together with <blocking passage> disabled.
elevation	obj::elevation	The elevation (height above sea level) of this tile. It is used for weather calculations and should be in the range -32000..32000. The elevation of a tile must be set in the bottom-most game object; elevation values for non-bottom-most game objects are ignored by the Crossfire server.
glow radius	obj::glow_radius	If <glow radius> is set to a value greater zero, the object appears lit up on dark maps. <glow radius> can be a value between 0 and 4, the higher, the more light does the object emit.
identified	FLAG_IDENTIFIED	If an item is identified, the player has full knowledge about it.
image	obj::face	The image-name defines what image is displayed for this object in-game.
invisible	obj::invisible	Generally makes the object invisible. Depending on the object-type, some can be made visible by the show_invisible spell. If in doubt, test it. Putting an invisible object under the floor always prevents it from being shown.
match = having	obj::last_sp	Enabled means having that object is a match. Disabled means not having that object is a match.
match arch name	obj::race	This string specifies the object we are looking for: We have a match if the player does/don't carry an object of archetype <match arch name>.
match key string	obj::slaying	This string specifies the object we are looking for: We have a match if the player does/don't carry a key object or a mark with identical <key string>. Note that key objects usually appear as "passports" in this context. A typical example is the city gate mechanism of Scorn.
match type	liv::hp	This value specifies the object we are looking for: We have a match if the player does/don't carry an object that is of type <match type>. Example: Set <match type> 15 (type 15 => weapon) and <blocking passage> enabled. Now you have an inventory checker blocking all players that carry any kind of melee weapon. To pass, a player is forced to leave behind all his weaponry... bad news for a warrior. ;)
material	obj::material	This bitmask-value informs the player of which material(s) the object consists. Material does also affect how likely the object can be destroyed by hazardous spell-effects.
name	obj::name	This is the name of the object, displayed to the player.
non-pickable	FLAG_NO_PICK	If set, the object cannot be picked up (Neither by players nor monsters).
number	obj::nrof	This value determines the number of objects in one stack (for example: 100 gold coins => "number = 100"). You should set this at least to one, for any pickable object - otherwise it won't be mergeable into a stack.
plural name	obj::name_pl	This is the plural name of the object. A plural name must be set for all items that can be picked up and collected by the player.
remove match	obj::last_heal	<remove match> means remove object if found. Setting this is usually not recommended because inventory checkers are in general invisible. So, unlike for altars/ locked doors, the player won't expect to lose an object when walking over that square. And he doesn't even get a message either. So, if you enable <remove match>, make sure to inform the player what's going on!
smooth level	obj::smoothlevel	If <smooth level> is set to a value greater zero, the object will be drawn partially over adjacent squares having a lower <smooth level> value. The value must be between 0 and 255 (inclusive); 0 means "never overlap adjacent squares".
title	obj::title	This is the object's title. Once an object is identified the title is attached to the name. Typical titles are "of Mostrai", "of xray vision" etc.
unpaid	FLAG_UNPAID	An <unpaid> item cannot be used unless a player carried it over a shop mat, paying the demanded price. Setting this flag makes sense only for pickable items inside shops.
value	obj::value	Adds a certain value to the object: It will be worth that many times the default value from it's archetype (E.g. "value = 3" means three times worth the default value). Value for buying/selling will be further modified by various factors. Hence, testing values in-game is usually inevitable.
weight	obj::weight	This value defines the object's weight in grams (1000g is 1kg). Objects with zero weight are not pickable for players. Still, set the "non-pickable"-flag for explicitly non-pickable objects (hey, this is opensource.. you never know ;) ).
