Feature Information
The Item Option System is a feature that was implemented in 2015-02-26 clients, allowing equipments to have up to 5 additional effects similar to cards or enchants. Each equipment is capable of having 5 information bars above the card slot/enchant bar that describes the effect of the option it is infused with.
New Script Commands (The following snippet is available in doc/script_commands.txt.)
*getequipisenableopt(<equipment slot>)
This function checks if the equipped item allows the use of bonus options.
Returns 1 if allowed, 0 if not.
---------------------------------------
*getequippedoptioninfo(<info_type>);
This function is to be used with the scripts of contents listed in
db/item_options.conf only.
Returns the value of the current equipment being parsed.
If the equip was not found or the type is invalid, -1 is returned.
---------------------------------------
*getequipoptioninfo(<equip_index>,<slot>,<type>);
Gets the option information of an equipment.
<equipment_index> For a list of equipment indexes see getequipid().
<option_slot> can range from 1 to MAX_ITEM_OPTIONS
<type> can be IT_OPT_INDEX (the ID of the option bonus, @see "Id" or "Name" in db/item_options.conf) or IT_OPT_VALUE (the value of the bonus script of the equipment, @see "Script" in db_item_options.conf).
returns the value of the slot if exists or -1 for invalid slot, type or slots.
---------------------------------------
*setequipoption(<equip_index>,<slot>,<opt_index>,<value>);

<equipment_index> For a list of equipment indexes see getequipid().
<option_slot> can range from 1 to MAX_ITEM_OPTIONS
<type> can be IT_OPT_INDEX (the ID of the option bonus, @see "Id" or "Name" in db/item_options.conf)
<value> The value of the type to be set.

Release Notes
This system allows the infusing of equipments with bonus item options.
This feature is constrained to clients of packet versions greater than or equal to 20150226.
Item Options and their effects are defined server-side in db/item_options.conf and client side in data/luafiles514/lua files/datainfo/addrandomoptionnametable.lub
The ID of the option must tally with the correct index of the description provided in the client side file.
IT_OPT_* keys and MAX_ITEM_OPTIONS macro are also exported from the source as constants.
If you wish to disable item options for certain (equipment) items, an additional flag `disable_options` has been added to the item sql tables, and as `DisableOptions: true/false (boolean, defaults to false !!for equipments only!!)` to the item_db.conf files.
Documentation is provided for script commands.
If upgrading, don't forget to run the sql upgrade files!
