[Epic Release] Cross Server GM Chat

[Pwntzyou]

External GM Chat

You sure did read the title right!

I am releasing an addon that lets you talk to other game masters on other servers!


Still confused?

Ex: You are the owner of a private server with four realms... you install my add-on to all four realms and now game masters can talk to each other regardless of their realm!

Ex: You and your friend are messing around on your own personal private servers, you both have the add-on installed and configured, you can talk to each other on separate realms!


Information
I have made a video on how to add this into your core and get everything working.

**Note the sound did cut out toward the end of the video when I was explaining the config files

Most of the info on the config files are self explanatory, but you do need to make sure that the port and auth_code match up in both the main server's config file and the other config file.

(You also need to move the config file from
\External_GM_Chat\External_GM_Chat\Files\Config
to where your private server's config files are located

Enjoy!!


P.S. The command is
.global text

ex: .global hello my name is pwntzyou!

Great idea, great programming. +3 Rep well deserved.

It would have been nice if you had done it through the realm server, though, rather than a separate chat server.

p.s. it's nice to see real programming like this, rather than the typical repack, LUA script, or copy-paste C++ script that you usually see here

[Sounddead]

GJ, didn't think you'd release it :O +rep

Much thanks!

And to the realmlist thing, I considered doing it like that, but in development it was its own program, and I just left it that way

[project anthrax]

wow sick man +some

[stoneharry]

Pastebin please?
Apart from that looks good, did you get inspred by the project bloodfire that failed by any chance? Now you just need to make a global channel for players as well (it would be more use for them imo) and it will be perfect. +Rep

[Ground Zero]

This is a True Script. +Rep x5 Very nice indeed.

Pastebin what?

I was thinking about a global player chat but if you think about 500+ players talking at once... T_T

[stoneharry]

And also yea I did... I was thinking about a global player chat but if you think about 500+ players talking at once... T_T

Pastebin the script/patch so that people can preview it without having to download.
Also 90% of private servers have less than 100 on at once.

Done, added code-boxes for the two C++ files
(The actual server is closed source and pre-compiled)

Great work pwntzyou! +Rep.

Although I didn't really like the color contrast and you could have done it way better if you added in some more features. You also should have used rapidshare instead of filebeam.

Well, great effort, but it seems quite useless to me. O.o
