Example:
switch(input("Password?",,password_character="*")) if("cheese") usr << "Correct!" else usr << "Wrong password!"
This would make the text that you type in the text box, appear to be whatever character you specify in the input line. If you still dont know what I mean, heres a little something to show you what I mean:
No password character:
Password?
Cheese
Password character defined as "@":
Password?
@@@@@@
Hope you understand.
-Rcet
input("Password?") as password
