MooUnit

Overview

MooUnit-1.0 is a library that provides mappings between GUIDs, unit IDs, and names.

The unit IDs tracked by the library are:

• "player"
• "vehicle"
• "pet", "pettarget"
• "target", "targettarget"
• "focus", "focustarget"
• "arena1", ..., "arena5"
• "arena1target", ..., "arena5target"
• "arenapet1", ..., "arenapet5"
• "arenapet1target", ... "arenapet5target"
• "boss1", ..., "boss5"
• "boss1target", ..., "boss5target"
• "party1", ..., "party4"
• "party1target", ..., "party4target"
• "partypet1", ..., "partypet4"
• "partypet1target", ..., "partypet4target"
• "raid1", ..., "raid40"
• "raid1target", ..., "raid40target"
• "raidpet1", ..., "raidpet40"
• "raidpet1target", ..., "raidpet40target"
• "nameplate1", ...
• "nameplate1target", ...

API Methods

GetUnitByGUID

Returns a list of units currently associated with the GUID.

unit1, unit2, ..., unitN = lib:GetUnitByGUID(guid)

Arguments:

• guid – string: GUID

Returns:

• unit1, unit2, ..., unitN – list of strings: variable-length list of unit ID strings

GetNameByUnit

Returns the name currently associated with the unit.

name = lib:GetNameByUnit(unit)

Arguments:

• unit – string: unit ID, e.g., "player", "party1", "raid15", etc.

Returns:

GetUnitByName

Returns a list of units currently associated with the name.

unit1, unit2, ..., unitN = lib:GetUnitByName(name)

Arguments:

• name – string: name or name-realm

Returns:

GetNameByGUID

Returns the name currently associated with the GUID.

name = lib:GetNameByGUID(guid)

Arguments:

• guid – string: GUID

Returns:

• name – string: the name associated with the GUID, name or name-realm

GetGUIDByName

Returns a list of GUIDs currently associated with the name.

guid1, guid2, ..., guidN = lib:GetGUIDByName(name)

Arguments:

• name – string: name or name-realm

Returns:

• guid1, guid2, ..., guidN – list of strings: variable-length list of GUID strings

GetPetUnitByUnit

Returns the unit ID assigned to the pet for the unit, even if the pet does not exist.

petUnit = lib:GetPetUnitByUnit(unit)

Arguments:

• unit – string: unit ID, e.g., "player", "party1", "raid15", etc.

Returns:

• petUnit – string: unit ID, e.g., "pet", "partypet1", "raidpet15", etc.

GetOwnerGUIDByGUID

Returns the GUID of the owner of the pet or vehicle GUID if both are on the group roster.

ownerGUID = lib:GetOwnerGUIDByGUID(guid)

Arguments:

• guid – string: GUID of the pet or vehicle

Returns:

• ownerGUID – string: GUID of the owner

GetTargetUnitByUnit

Returns the unit ID assigned to the target for the unit, even if the target does not exist.

targetUnit = lib:GetTargetUnitByUnit(unit)

Arguments:

• unit – string: unit ID, e.g., "player", "party1", "raid15", etc.

Returns:

• targetUnit – string: unit ID, e.g., "target", "party1target", "raid15target", etc.

IsGUIDInGroup

Returns whether the GUID is on the group roster.

boolean = lib:IsGUIDInGroup(guid)

Arguments:

• guid – string: GUID to test group membership

Returns:

• boolean – boolean: true if the unit is on the group roster, or false otherwise

IterateRoster

Returns an iterator that gives key-value pairs of GUID and unit ID for members on the group roster.

for guid, unit in lib:IteratorRoster() do
    ...
end

RegisterCallback

Registers a function to handle the specified callback.

lib.RegisterCallback(handler, callback, method, arg)

Arguments:

• handler – table/string: your addon object or another table containing a function at handler[method], or a string identifying your addon
• callback – string: the name of the callback to be registered
• method – string/function/nil: a key into the handler table, or a function to be called, or nil if handler is a table and a function exists at handler[callback]
• arg – a value to be passed as the first argument to the callback function specified by method

Notes:

• If handler is a table, method is a string, and handler[method] is a function, then that function will be called with handler as its first argument, followed by the callback name and the callback-specific arguments.
• If handler is a table, method is nil, and handler[callback] is a function, then that function will be called with handler as its first argument, followed by the callback name and the callback-specific arguments.
• If handler is a string and method is a function, then that function will be called with the callback name as its first argument, followed by the callback-specific arguments.
• If arg is non-nil, then it will be passed to the specified function. If handler is a table, then arg will be passed as the second argument, pushing the callback name to the third position. Otherwise, arg will be passed as the first argument.

UnregisterCallback

Unregisters a specified callback.

lib.UnregisterCallback(handler, callback)

Arguments:

• handler – table/string: your addon object or a string identifying your addon
• callback – string: the name of the callback to be unregistered

Callbacks

MooUnit-1.0 provides the following callbacks to notify interested addons.

MooUnit_PetChanged

Fires when the pet associated with an owner has changed. This can happen if a pet is dismissed and a new pet is summoned.

Arguments:

• petUnit – string: unit ID of the pet

MooUnit_RosterUpdated

Fires when the roster of the party or raid group has changed.

MooUnit_UnitChanged

Fires when a unit that we are tracking has changed.

Arguments:

• guid – string: GUID associated with the unit ID
• unit – string: unit ID of the unit that has changed
• name – string: the current name associated with the unit ID.

MooUnit_UnitJoined

Fires when a new member is added to the group roster.

Arguments:
