[Dev] [Open Source] publicLaunch

This is a launcher i'm making for the public, Open-Source. It will include an "antihack" based on a snippet I found by Vengeance. <3 <3 <3. CRC32 Checking, and goodies like that. Here is the basic outline [Three seconds time it took] Yes it's a console. [For now, I might make a GUI later]

Update:

Pretty much done, just need to add some security features. [;

Going to post in release section now.

Umm, I have a question... What excactly is the point of this, like what does it provide? I think you were doing a fine job on that custom launcher.

This one is for public, the other one is going to have the features of my VIP, and I did this one for shits and gigs, the Custom one is for a specific server, and NOBODY gets the source except for me. :rolleyes:

Bad Code.

4-5 minutes of developing. Get good kid.

You've also done this more than me, longer than me, you have more experience and I hardly do it. Thanks.

Also, learn to use a fucking array instead of crc322 crc3222 etc.

Why would you release a 5-minute dev job? You know you'll be mocked for it, and doubtfully anyone will use it.

Seriously, use a real array, and quit using such large conditional nests - in this case, they're unnecessary, and provide less readability.

Me and him started it together. Then he stopped going on MSN, and wouldn't open the forum, then he wanted to make it a blog instead of a forum, so I just setup all the shit and talked to him, and now I run it. Not sure if he is going to help or not. Therefor, I didn't steal anything + I'm the one who got someone to get us the domain.

Jacob, you wrote Bullshit, you never defined what your "GunzPacket" object even was.

Except a Class, but it still doesn't represent a packet, like I said, you wrote bullshit.
And why do I get the idea you basically copied your bullshit from the NOX source you were given?

Why would I have to define it? Want a quick fucking example?

Code:

---

            packet = new GunzPacket(0x4B7, PacketEncryption.Encrypted, 0);
            packet.Write(uidChannel);
            packet.Write(nChannelType);
            packet.Write(szName);
            packet.Write(true);
            packet.Finalize(client.m_bEncryptKey);
            client.m_nClientSocket.Send(packet.getPacket());

There's your example, next, nothing was copied from Nox. Everything was wrote by me, so, I'm guessing you're Kolie?
