Get a global variable, from a string.

getglobal("globalName")

Parameters

Arguments

("globalName")

globalName

String - Name of the global you want to get.

Returns

The object from the given string.

Details

This function is used to get an object if you generate the name of the object manually in your script:

i = some_dynamic_number;
local curFrame = getglobal("myFrame"..i)

You can immitate getglobal() by using the following script:

_G = getfenv()         -- set _G to the global environment once at the beginning of your script
 ...
myvar = _G[globalName] -- this is what getglobal() does

Remark from Airlag:

getglobal() is doing a little more than _G[globalName]

It allso finds _G[anything][globalName] or _G[anything][deeper][globalName] or any deeper hidden child object.
