[Request] 5165 Class Ban
Hello to whoever bothers to read this.
I am currently working on the 5165 NCOS and I do not intend to divert from it any time soon.
I am trying to add a ban on ninjas, and I have seen this done in other 5165 servers. I know around where the code is needed, but I don't have the knowledge of what should be added to it.
Code:
FS = new FileStream(@"C:\OldCODB\Users\" + Account + ".usr", FileMode.Append);
BW = new BinaryWriter(FS);
BW.Write((byte)Name.Length);
BW.Write(Encoding.ASCII.GetBytes(Name));
BW.Flush();
FS.Flush();
BW.Close();
FS.Close();
Game.Character C = LoadCharacter(Name, ref Account);
if (C != null)
{
C.UniversityPoints = 0;
SaveCharacter(C, Account);
}
}
catch { return "Error! Try again."; }
return "ANSWER_OK";
}
return "Error: Character already exists!";
}
catch (Exception Exc) { Console.WriteLine(Exc); return "Failed to create the character."; }
}
}
Any help is welcome. Any comments about downgrading my source will most likely be ignored, or I will give you a reason on why I won't.
**EDIT
Also, if anyone has all of the files for the dragon souls, could you please upload them?
I can't find a download anywhere.

I doubt that's the code, for multiple reasons.
1. None of the other code in that area matches,
2. There wouldn't be a "Class" or "Ninja", that I know of,
3. It creates an error when entered, which is fully expected.
4. I know that there are more codes to go around that, especially around the text that pops up when you attempt to create a character.
If you think I am a rookie, you are wrong.
And congratulations at failing to be an *******.

I believe he was expecting directly the code, not an idea on how to create it himself.

My slight knowledge of C# is in the NPC/Command making area. I can make NPCs, and I can make commands based on other codes in the source, but I do not recognize the codes in the database.cs, I apologize for my earlier comments.
As for the code you gave, I believe it would work, except the source does not recognize "client" "class" and "message"

Just go to the Character creation sections add an line where it checks the class, if it's 50 make it pop up a message telling you are not allowed, i did that while ago and it worked.
It won't require more C# knowledge than making an NPC check ffs.
If (Character.Profession == 50)
{
Message ("You are not allowed to create ninja")
return;
}
Something like this, now look in your source and figure it out, not that had.

So, below
catch { return "Error! Try again."; }
return "ANSWER_OK";
}
return "Error: Character already exists!";
I added:
if (Job == 50)
{
return ("You are not allowed to create ninja");
}
And now, every account, regardless of class, gets the error message "Error! Try again.", and on second attempt, it says "Error: Character already exists!".
It also adds a new char file, with given name. If you try to login with that acc and pass, it takes you back to the character creation.

because you are doing it wrong, you have to check for job right before it creates it and sends the answer....
It easy, just try different places every time, it's basic logic here.

I love epvp. He was trying to help you with a basic pseudocode.

We've given you tons of help. We're telling you the logic that needs to be entered in to block a specific character from being created.
Your job is now this.
#1: Locate where characters are created (it will be reading from a packet the client sends)
#2: Determine where in the packet the player's profession is stored (it should be obvious because the source already has to read it)
#3: Check that profession against what is either allowed or banned (in this case ninja profession which is base profession 50... you should really be going with a list of allowed base professions though or I can just spoof a packet and create a max promotion character at lvl 1)
#4: Return an error to the client if they try to create a character with a profession you don't want them able to use

And I thank you all very much for the help you have given me.
I only have one issue left, for some reason now no class can be made. Ninja is fully banned, but I'm not sure if I've left something out of the code I made with your help. Currently the entire creation code is as follows:
Code:
public static string CreateCharacter(string Account, string Name, ushort Body, byte Job)
{
if (Job == 50)
{
return ("Ninja is not allowed. Pick another class.");
}
try
{
if (File.Exists(@"C:\OldCODB\Users\" + Account + ".usr") && !File.Exists(@"C:\OldCODB\Users\Characters\" + Name + ".chr"))
{
try
{
FileStream FS = new FileStream(@"C:\OldCODB\Users\Characters\" + Name + ".chr", FileMode.CreateNew);
BinaryWriter BW = new BinaryWriter(FS);
BW.Write(Account);
BW.Write((uint)Program.Rnd.Next(1000001, 19999999));
if (Body == 1003 || Body == 1004)
BW.Write((ushort)1);
else
BW.Write((ushort)201);
BW.Write(Body);
BW.Write((ushort)(410 + (Program.Rnd.Next(5) * 100)));
BW.Write((ushort)1010);
BW.Write((ushort)61);
BW.Write((ushort)109);
BW.Write((ushort)0);
BW.Write(Job);

BW.Write(Str);
BW.Write(Agi);
BW.Write(Vit);
BW.Write(Spi);

catch { return "Error! Try again."; }
return "ANSWER_OK";
}
return "Error: Character already exists!";
}
catch (Exception Exc) { Console.WriteLine(Exc); return "Failed to create the character."; }
}
}
The code I added is at the very top, under the first line,
Code:
if (Job == 50)
{
return ("Ninja is not allowed. Pick another class.");
}
Now the message comes through for "Ninja is not allowed. Pick another class." every single time, without creating a new character. Every other class, it first says "Error! Try again." and then if you try again with the same name, it says "Error: Character already exists!", and the new character that it created has no account, its simply a character created. You can't login with it, and you can spam the database with accounts.
What is missing?

Now, Ninja isn't banned, instead every other class is banned with the No Ninja message. Also, Ninja now has that error about the "try again' and then "character already created". I think that this didn't fix anything, but actually reversed the desired effect 0.o
