WoWWiki>Egingell: It's new

2007-07-18T02:15:12Z

It's new

New page

{{userfunc}} 
<center>'''{{PAGENAME}}''' ''- by [[User:Egingell|Egingell]] -''</center>

Returns a list of values in whatever order you specify in ''order'' and only those you specify in ''order''. Mostly useful for functions that return multiple values.
ret1, ret2, ... retN = {{PAGENAME}}(order, functionCall)

== Function Parameters ==
=== Arguments ===
:(order, functionCall)
:;order : number or numeric string
:::e.g. 17 or "17"
:;functionCall : a function call that returns a list of values.
:::e.g [[API GetItemInfo|GetItemInfo]]([[ItemLink|itemLink]])

=== Returns ===
:the number of and order of return values depend on the number specified in ''order'' and on the function passed to functionCall

== Example:1 ==
local sName, iRarity, sType, iStackCount = {{PAGENAME}}(1368, [[API GetItemInfo|GetItemInfo]](16846));
message(sName..","..iRarity..","..sType..","..iStackCount);

====Result:1====
: {{PAGENAME}} will return the first, third, sixth, and eighth return values (in that order) from [[API GetItemInfo|GetItemInfo]](16846)
: A message box will pop-up with -
Giantstalker's Helmet,4,Armor,1.

== Example:2 ==
local reason, name = {{PAGENAME}}(61, [[API GetAddOnInfo|GetAddOnInfo]]("Uber Addon"));
if reason then
_ERRORMESSAGE(name.." didn't load.\nReason code: "..reason..".");
end

====Result:2====
: {{PAGENAME}} will return the sixth and first return values (in that order) from [[API GetAddOnInfo|GetAddOnInfo]]("Uber Addon")
: A error message box will pop-up with -
Uber Addon didn't load.
Reason code: MISSING

==Code==

local input = {}
