RotMG Unity Client Thread

[Azuki]

Let's see if not naming it works, since that wasn't the point of it.

There is already a client for Unity that has predictive autonexus and autoaim. The ones here aren't predictive and are just starting to get autoaim.

that's crazy. your point being?

just curious, can you list the programs you are using for the unity decompiling/hacking?

I'm trying to read packets sent by the client, but they don't seem decrypted properly. I also tried injecting dll into flash version, it also doesn't work. The cipher key and packet structures are from decompiled flash version, for rc4 i'm using crypto++ library. Is there something i'm missing?

_loc1_ = Crypto.getCipher("rc4",MoreStringUtil.hexStringToByteArray("6a39570cc9de4ec71d64821894c79332b197f92ba85ed281a023".substring(0,26)));
_loc2_ = Crypto.getCipher("rc4",MoreStringUtil.hexStringToByteArray("6a39570cc9de4ec71d64821894c79332b197f92ba85ed281a023".substring(26)));
serverConnection.setOutgoingCipher(_loc1_);
serverConnection.setIncomingCipher(_loc2_);

just curious, can you list the programs you are using for the unity decompiling/hacking?

il2cppdumper, dnspy, ida 7.0, visual studio

There is already a client for Unity that has predictive autonexus and autoaim. The ones here aren't predictive and are just starting to get autoaim.

The guy from rbot, who made that client is doing it for money. No one here is trying to compete or release asap , i think people who make cheats for mpgh are having fun reversing games.

As index.html stated, were it a competition then people would keep all info to themselves but there have been some quality posts from azuki and index.html

also on another note, the rbot cheat has absolutely NOTHING to do with what we're doing here.
it's a simple proxy hack, and nothing special. we're doing internal work.

And besides, I've had an aimbot for over a week and linear extrapolation based on weapon data for 4 days now https://gyazo.com/e1f07b6760a38c1e428c8238d5f1e5f9 (shit cropping to hide info)

Collab with them then. It would sincerely speed up the process of making a client.

For anyone interested/wants to use this (probs just azuki and index.html lol) here are some of the option stringids of the menu (amongst a few other things)

I tried dcing some players with my krelay dc plugin and i found out that ppl exalt take way more packet spam to dc than flash.

Interesting. Is it still effective tho?

/snip

I mean Naru is gonna be opensource in a bit, I just have to tidy the source and add some more features

it works on flash players, tho it only lags exalt players
