Updating jOryx a Java RotMG Client

I seen that the client hasn't been updated to 27.7.5 yet.

I have a few more questions:
How do you get the new assets? Is it like getting the new packets?
How do you know what packets to send in the client and the encryption stuff that occurs in the client? Do you have to look in the source code or something?

Basically you can rip all the assets from the swf easily, its just a matter of programming the client to use them. You can also grab the rc4 keys which are used for decrypting/encrypting packets being received/sent. The server public key (for encrypting log in credentials) can also be found. I simply learned how to use these from joryx. Also the client is at a state where it logs you in for about 10 seconds before crashing (and it only shows a black screen, also chat doesn't work)

Maybe you should try this, if you haven't.
Use a proxy like krelay or realmrelay and track all of the packets that were sent, and look at the packet data, and add them into the client.
Is it showing a black screen because it hasn't been programmed to display sprites?

Whats realmshifter

if you read the main post, you'll find its the whole reason i started this thread

Ok, then I might try continuing it, it seems like a good project.

Sure if you can get past the point I got to, that would be awesome. I'm willing to help any way I can.

You're gonna need to find updated RSA/RC4 keys, new maps, and the updated hellopacket structure. G'luck.

Nope. RSA/RC4 keys were easy to find, and updated hellopacket structure is also easy to find + its also in realm relay, and krelay. Also, i'm pretty sure map data comes from the server when you connect.

Oh hey look, there is actually some life here too

It's also easier to figure out the formats from the client though. There were many attempts at this wayy back in the day though so most of the work was done way earlier then public proxies.

Most of the new assets don't require any new programming since the assets contain all the information required (picture, stat modifiers, health for enemies etc, aka "the .xml files"). There are some exceptions (new mechanics and such) but kabam rarely adds such content.

I wonder if anyone remembering me still floats around?

Sounds like a fun undertaking. I remember it wasn't that hard to update, shouldn't be much to change now either, I doubt kabam has changed the game much since I last played. The whole java client thing was something I took a shot at as well but I doubt I have the files anymore. Sounds pretty cool tho. Add me on skype so we can talk about it.

I agree. All data can be easily looked up in either KRelay or prod-recent private server sources.

Well, because I don't really like furyhunter's client, so I stopped and am now writing my own.

Yeah, I saw that as well. Either way, updating jOryx would probably mean changing/upgrading the client code as well, not just the underlying communication with the server. I believe the pets wouldn't really behave well on jOryx for example and as far as I remember it wasn't very polished. Since you'd probably rewrite or change a lot, the scope is pretty much the same either way. I've written a couple games with libGDX as well so I'd be glad to help if you need any.
