Script function

world.GetWorldIdList

Type

Method

Summary

Gets the list of open worlds - returning their world IDs

Prototype

VARIANT GetWorldIdList();

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.

Available in MUSHclient 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.

Return value

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.
