Generally speaking, there are two types of "things" in the game; characters and items. Compared to characters, items are very complex. Items have a number of different uses, for example a sword is an item that players can see and equip to increase the damage they can do in combat. Some items in the game can not be seen by the players, but they have as much impact on the player as their sword, for example, a memory item is equipped every time a player is under the effects of a spell. Some special types of item also have additional properties that can be accessed via scripts. The following tables detail the various properties of items in SphereServer:


References

References return pointers to other objects (e.g. the REGION reference allows you to access the REGION that an object is in). These can either be accessed by using <REFNAME> to return the UID (1 for object types that don't have UIDs) of the object or 0 if it doesn't exist, or by using <REFNAME.KEY> where KEY is a valid property/function/reference for the REFNAME object. Click on the name for more detailed information such as usage and examples.

Name Read/Write Description
CONT RW Gets or sets the character or container item that the object is inside. When an item's CONT is changed, it bypasses the typical behavior (for example, you can force an item to be "in" a container and bypass @dropon triggers, or force an item to be equipped to a player and bypass @equiptest and @equip triggers -- but be careful, because in this second scenario it may end up in an invalid layer.)
LINK RW Gets or sets the character or item that the item is linked to. Note, you can make circular LINK's, but a single item cannot be linked to more than one other item.
REGION R Gets the region that the object is in.
ROOM R Gets the room that the object is in.
P RW Gets or sets the position that the object is at.
SECTOR R Gets the sector that the object is in.
TOPOBJ R Gets the top-most character or item in the world that contains the item.
TYPEDEF R Gets the ITEMDEF that defines the item.

Properties and Functions

Here is a list of all item properties and functions. If a function is marked as readable then it can return a value when used as <KEY>. Click on the name for more detailed information such as usage and examples. If an attempt is made to access a property that does not exist on the item, the property from the ITEMDEF will be accessed instead.
