If you still wanna know how to do the custom name system well just read on.
When you store a variable in your code when you do your name system have
10 Hero's that are blank, then when it stores a letter lets say 26 (Z) it would have
Change Hero Name [Number of Hero: ] to Z and if you wanted to do capitals you would have 52 Variables and so on.
To show the hero name in a message you would have
Hi /N1(Or whatever it was) then /N2/N3/N4 and so on.
