View list of data type meanings

Description

Returns a variant array which is a list of the identifiers (IDs) of all open worlds.

This is safer than using GetWorldList because multiple worlds might have the same name.


Note: Available in version 3.39 onwards.


VBscript example
for each id in world.GetWorldIdList
  world.note id
next
Jscript example
worldlist = new VBArray(world.GetworldIdList()).toArray();

if (worldlist)  // if not empty
 for (i = 0; i < worldlist.length; i++)
   Note (worldlist [i]);
PerlScript example
foreach $item (Win32::OLE::in ($world->GetWorldIdList))
 {
 Note ($item);
 }
Python example
worldlist = world.GetworldIdList
if (worldlist ):
  for w in worldlist : world.Note (w)
Lua example
-- --------------------------------------------------
-- Example showing sending a message all worlds
-- --------------------------------------------------

function SendToAllWorlds (message)

  for k, v in pairs (GetWorldIdList ()) do 
    GetWorldById (v):Send (message)
  end
end

SendToAllWorlds ("say Hi there")
Lua notes
See the description for GetWorld for more discussion about using "world" variables in Lua.
Returns If there are no worlds then the return value is empty. Use "IsEmpty" to test for this possibility.

Otherwise, it returns a variant array containing the Ids of all the worlds. Use "ubound" to find the number of worlds in the list. You can then use "GetWorldById" to return a reference to that world.
Introduced in version 3.39
