A function added by the New Vegas Script Extender.
Returns a string variable constructed from the specified string and up to 20 formatting arguments.
If no formatting is required, this function is not necessary, as the Let command can be used to assign string variables. Note that Let supports concatanation and the ToString($) function which can usually achieve the same result as formatting.
(string_var) Sv_Construct Literal:string Formatting
string_var my_string int iValue ref rActor ; Used to construct a formatted string: let my_string := Sv_Construct "iValue equals %g and rActor's name is %n", iValue, rActor
Typically you can skip Sv_Construct and use concatanation with ToString($) instead of formatting, if you prefer:
let my_string := "iValue equals " + $iValue + " and rActor's name is " + $rActor
