X2_IP_ADDPROP_POLICY_* Constant Group
These constants are only available if you include x2_inc_itemprop in your script.
They are used in the IPSafeAddItemProperty command in the same include file and determine what should happen when adding a type of itemproperty to an item that already has one of that type.
|Adds itemproperty in any case - do not Use with OnHit or OnHitSpellCast props!|
|Itemproperty won't be added if any property with same type, subtype and durationtype already exists.|
|Removes any property of the same type, subtype, and durationtype before adding.|
