[Release]Basic C++ Method Of New Commands

[falseprophet]

Ok guys here is a basic source code to do custom commands. You do the PHP Pages on your own. Ok, here it is.

Credits Given Where Code Is Posted. Note: I will not explain it.

To Force Gunz to load your DLL, here's an example I did with the BR Client:

[hlcm]

i am not understand ?

complie that code you posted to dll file -> then inject it into Matchserver ? right ?

[falseprophet]

No, this is for Gunz.exe

[Kingston]

Thanks.

[thebestkiller]

what does it do?
EDIT : nvm i know what it does
but
PLZ TELL THE STEPS !!

[Zephyr]

the steps were included...
read it properly through...
if you still don't get it, then too bad...

[wesman2232]

gah noobs grave-digging again.
seriously needs to be a rule against this.
