[TUTORIAL] Gamecore r40250 Source Code Configuration

[redrpci2008]

Hello, community!

This tutorial was made for the C++ noobs (those people who don't know the difference between a bool and an int), so please don't rage at me .

In this short how-to topic, I'll show you how to configurate the basic functions of the core from the source code, so you won't have to mess up with Hex editors, .diff files and so on, because there may be a high chance that the adresses (or offsets! - those 0x3678ABCD -like things) won't match up, because of the different compilers which are used etc...

So, the first thing you should do: choose your favorite branch (I'm using mainline ), and follow this path:

Srcs / Server / game / src

In the src folder, you should find a source file called config.cpp. Open it. (It's logic, yeaah!)

Starting with line 24, you should encounter the declaration values. Here you will do your work:



Warning! Some (shitty) compilers might give you some errors if you don't leave the tab spacing default. So, in order to prevent mistakes, I would advise you to enable the "Show all characters" function. In Notepad++, you only have to click this button:

Warning no. 2! You can't change, for example, a string with an integer value, or a bool with a char! For example, bool test = true; may only have the values true or false! Google for "C++ data types" in order to learn more!

Well, if you got the preps right, this is a bit of what you can do:

Change the connection values

 Spoiler

Between lines 26 - 36, you can predefine the values which you would usually set in the "CONFIG" files.

Change the server type

 Spoiler

Between lines 43 - 47, you can change the server type.

Note: these integers act like bools, 0 means false and 1 means true.
Note: the int auction_server will be considered only if __AUCTION__ is defined!



For example, if you change test_server from 0 to 1, you would make the server GM-Mode by default. It is useful for test servers with a few number of players.

Change the limits

 Spoiler

Between lines 51 - 59, server limits can be changed.
What does each mean?
guild_mark_min_level - the minimum level of a guild in order to upload a guild image;
no_wander - ??
g_iUserLimit - the limit of users that can be connected at the same time at this core. By default, it is the maximum limit + 1 of an 16-bit signed integer (32768). I think it might be set to higher values, if it is changed from an int to a long, but it might create bugs.
g_szPublicIP[16] - the public IP of the server (maximum limit of 16 characters!) If left default, the server should find the IP by its own.
g_szInternalIP[16] - the internal IP of the server. It behaves as the previous. It might be useful if you have to set up multiple servers in a LAN network.
g_bSkillDisable - disables the use of the skills (Who on Earth would want to do this? )
g_iFullUserCount - the number of online players that must be reached in order the client to display the "FULL" value (next to the channel, instead of "NORM" or "BUSY")
g_iBusyUserCount - the number of online players that must be reached in order the client to display the "BUSY" value (next to the channel, instead of "NORM" or "FULL")

Foreign-empire whisper and Client version checking

 Spoiler

Here, you can modify these values:

g_bEmpireWhisper - Enable whispering to a player which is in a foreign empire (I'm not 100% sure about this one)

g_bCheckClientVersion - Enables the checking of the client version.
g_stClientVersion - Current client version.
You may want to check this topic, in order to do the client stuff:

At last, but not least, changing the ItemShop URL

 Spoiler

This can be done by changing the line 108.

The g_strWebMallURL should NOT contain http:// and the ending backslash, because this is the way it works. The full URL (with the player ID, account ID and other stuff) is declared somewhere (I haven't searched yet) in the code, by this variable.

I hope this topic is useful for somebody, and I would like to have some feedback, as I haven't really tested these, because my Windows Server 2003 on my other computer is doing some updates at the moment...

Have a nice day!

looks interesting - time to learn c++ !
Thanks for your Tutorial

I think your an C++ noob too. An bool is an Byte which is 0 or 1. not an int.

(And for .RoThe, exactly its a Bit but the CPU cant adress anything smaler than a Byte.)

No, a Boolean has only 1Bit length. It can have either the value 1 or 0, there is no more space needed. Just for the record ^^

thats what he said^^

1 Byte =/= 1 Bit

1 Byte = 8 Bit

At the least its a Byte because the CPU cant address anything smaller

Sry reading wrong is a big strengh of mine

[lukeido]

What is the difference of theese branches?

Alright thanks to your answer, I looked it up.

In fact it seems that the CPU indeed could adress bits, but it would be too slow.

Nevertheless I was wrong, thanks^^

Please tell me how the hell do you store the value 4571 in a bool I know that you can convert a bool to an int, but not viceversa!

That not an bool an bool can only be 0 or 1 ( false / true )

Boolean type: The boolean type, known in C++ as bool, can only represent one of two states, true or false.

You can save a char in bool (0 to 255) but a boolean is not always saved as a char, it could also be a long.

*(Unsigned char*)&a_bool = a_range_from255to0

I think your talking about Microsoft's "BOOL", iam talink about "bool / boolean".
Ive googled it and cant find anything wth an bool with a range of 0- 255.

Google says ALWAYS boo, = true / false (0/1)
