String variables are added by NVSE 4. A string is simply some combination of text characters and exists widely in the vanilla game. A string variable allows you to store a string in a similar way to any other variable, and a wide range of functions allow powerful capabilities for them.
String variables are very simple to use, provided you also use Let instead of set .. to .. and 'if eval' instead of simply if. To appreciate the full range of possibilites available, a tutorial is available.
Simple Example
string_var my_string let my_string := "this is my string" MessageEx $my_string ; * note: the MessageEx function requires you to include '$' (short for 'ToString') before the variable name if eval my_string == "this is another string" ; do something. Obviously this is false in this case. endif
To use String Formatting, you need to use Sv_Construct:
string_var my_string int MyInt let MyInt := 5 let my_string := Sv_Construct "the value of MyInt is %g", MyInt
