With this function you can create a new string made up of two strings, where one has been inserted into the other at a given position. It can be useful, for example, to add a user name into a predefined text and so make the player of your game feel more involved in the action.
string_insert(substr, str, index);
|substr||The substring to be inserted.|
|str||The string to be copied.|
|index||The position in characters of the string to insert the substring.|
str2 = string_insert(username, "Hello, , how are you?", 8);
This will insert the string in the "username" variable into the given phrase with the resulting string looking like this: "Hello, NAME, how are you?".
