1: There is a separate launcher as i pointed out more then one time in both tutorial and in this thread. For the launcher there is english and hungarian.
The language is either english or hungarian depends on wich launcher you use. SBRW\Webserver\www\Client\
Launcher-Installer.exe - English Client
Launcher-Installer-HUN.exe - Hungarian Client
No other options, the language in launcher settings are ONLY for the game. NOT for the launcher. It means it will download the selected language pack from your cdn. Therefor, you can translate the launcher if you are compile from source code from github(your on your own) or you can use DNSPY on the launcher itself to edit the source/translate but that is a long process. The client has only ONE language. It is hardcoded in the exe upon compiling.
As for the website language: You need to translate it your own. If you need help with hungarian language, use google translate
2: you need to add your own server like this:
You must be registered to see links
BUT: if you edit on the webserver(SBRW\Webserver\www\
serverlist.json to your IP) and change the domains(Client launcher folder\domains\) in your client's folder you wont need to add your own server but if you do, you need as shown above.
You can edit the installed launcher domains here:
cert_domain.txt
file_domain.txt
main_domain.txt
ModNet.txt
static.txt
static_alt.txt
For the custom CDN i do not know wich one is needed, but you can try one by one, the static alt is needed if the simple static one is not available.
3: Yes. You need edit cdn and web server stuff. in SBRW\Webserver\www\
cdn_list.json AND you need to setup the server, upload the webserver content for the new server.... it might(most probably) require extra steps, i never did that but you can do it.. you night need to do other things too... IDK never done it; so... trial and error XD Note: You can add more cdn too. If you have more than one server for mirrors in json, you need to separate with , comma.
Just FYI for everyone who want to change stuff: You can change 88 and 444 and other ports to suit your needs, almost all of those are changeable(i am not sure in Openfire with 5222 but the rest i am sure of it...) but the other ones are sure, but you WILL need to edit mysql, and other config files to suit this settings, i did chosen 88 since lot of machines are using 80 already... so it will not conflict. But i dont have time for creating a tutorial for everything so, you will need to be creative
I also do not know every answer regarding this XD
