WoW API < setglobal

Set a global variable, from a string.

setglobal( "globalName", value )

Deprecation[edit]

Both getglobal and setglobal are deprecated and replaced with the '_G[]' [1] the global table. Their functionality will be removed from the game at a future date.

Replace all references of 'getglobal':

var = getglobal(varName)       --getglobal deprecated
var = _G[varName]              --new syntax to get a global

Replace all references of 'setglobal':

setglobal(otherName, otherVar) --setglobal deprecated
_G[otherName] = otherVar       --new syntax to set a global

Parameters[edit]

Arguments[edit]

("globalName", value)
globalName
String - Name of the global you want to change.
value
Any - Value you want to set the global to.

Returns[edit]

Always returns nil.

Example[edit]

/script setglobal( "MyVariable", 1234 )

Result[edit]

MyVariable = 1234

Details[edit]

As of the introduction of getfenv() into the API, setglobal() and getglobal() are somewhat superfluous. You can always do something along the lines of:

 local _G = getfenv()
 local prevval = _G["MyVariable"]   -- "getglobal()"
 _G["MyVariable"] = 1234            -- "setglobal()"

Function calls always cost some overhead, so if a large number of getglobal calls are being made, the getfenv table will be a faster route. Note that for few or infrequent calls the performance gain of this method is negligible.
