Creates a GUID - Global Unique Identifier
View list of data type meanings
This generates a unique GUID (Global Unique Identifier). This is guaranteed to be unique throughout the world, and at any time (ie. completely and utterly unique) provided you have a network card in your PC, as part of the GUID is the MAC address of the network card, which are manufactured to be unique world-wide. If you do not have a network card, there is a small possibility that GUIDs generated by two PCs (both without network cards) might be the same.
The GUID will look like this: 6B29FC40-CA47-1067-B31D-00DD010662DA
The purpose of this is to give you a way of having a unique identifier (eg. for a variable). If you were to use it for that purpose you would have to add a letter to the front, as variables must start with a letter, not a number, and change hyphens to underscores. eg.
uniqueid = "X" & world.replace (world.createguid, "-", "_", true)
These numbers may seem cumbersome, but at least if you use them you are guaranteed of a unique identifier. The last 12 characters are the hardware MAC address of your network card (in the example above, "00DD010662DA"), so if you wanted an identifier that was unique for your PC, but not necessarily around the world, you could trim off the last 13 characters (eg. "6B29FC40-CA47-1067-B31D" would be unique on this PC). eg.
uniqueid = "X" & left (world.replace (world.createguid, "-", "_", true), 23)
To save a bit more space you could even get rid of the hyphens altogether. eg.
uniqueid = "X" & left (world.replace (world.createguid, "-", "", true), 20)
In this case the identifier is only 21 characters (including the "X") and will be unique on this PC.
Contrast this to "GetUniqueNumber" which only returns a unique number for this session of MUSHclient. Thus, the numbers (from "GetUniqueNumber") will not be unique over multiple sessions.
See also the new script function world.GetUniqueID.
Also, using random number generation for unique identifiers has a chance of returning the same number, depending on a) the seed given to the generator; and b) the way the generator must eventually recyle and regenerate the same sequence.
Available in MUSHclient version 3.23 onwards.
