API FontString SetFormattedText

Sets the text displayed in the font string using format specifiers. Equivalent to :SetText(string.format("format", value)), but does not create a throwaway Lua string object, resulting in greater memory-usage efficiency.

FontString:SetFormattedText("format" [, arg1, arg2, ... ])

• format : String - A string containing format specifiers (as with string.format).
• arg : A list of values to be included in the formatted string.
