İ want to add it but idk how

#1 when i connect the game its have to apear can anyone tell how can i do that i have gui of this file

#2 Ultimately you'll need to modify the source code to enable database connections. There are several resources that can explain it in more detail if you search for "login gui" in the Resources section.

Having that gui appear at startup is as simple as exec'ing the gui script file and modifying function GameConnection::initialControlSet() to push the gui when a player joins.
