Tags the item property with the provided string.

itemproperty TagItemProperty(
    itemproperty nProperty,
    string sNewTag


The item property to set the tag on.
A string to tag the item property with.


Tags the item property with the provided string. Any tags currently set on the item property will be overwritten.


The itemproperty commands are special constructors - they construct an itemproperty "object" which can then be applied to an item using the AddItemProperty command, much like effects need to be first constructed, then applied with ApplyEffectToObject.

This does not tag the itemproperty passed in, but generates a new itemproperty-with-tag which must be assigned to a variable or added. Only the newest tag will persist for any itemproperty.

This is used in conjuction with GetItemPropertyTag to uniquely identify an itemproperty, such as to remove itemproperties created by a specific interaction (see example below).


This function was added in 1.74.8149 of NWN:EE.
