[1.7.10] Patching vanilla class

Hello everyone,

I'm trying to get ServerConfigurationManager properly patched (using a ClassTransformer), but even if the class is correctly recognized by this method http://i.imgur.com/HsVBrh4.png and the patch method is called, the server does not seem to show any change.

I'm also patching another method of another class (that can be found both on client and server side) and it's perfectly working so I don't understand why this isn't  Emoticon unsure

No matter what I change of the target method of ServerConfigurationManager, I can't see any change when recompiled.

Moreover, the problem comes only when the source is recompiled, on a dev environment all gets patched.

Do you have any ideas about the solution/problem source?

I'm working with Doctor, the problem is that the patch to the other class is not replaceable with anything (but it's working) and the event is processed too late to prevent the login. If we use ServerConnectionFromClientEvent or PlayerLoggedInEvent the player gets kicked after his login fires in chat and if his connection is very poor, he can see the world for a short time.

And you need this new authentication method because...?

Because I need to change the authentication method to align it with my launcher credentials.

 

And them seeing the world for a very short time is a problem because...?

If someone try to login with another player usename (with wrong credentials) can see where he is in the world.

 

You can cancel the login chat message.

Yep, but prevent the login at a lower level seems more "clean".

Why do you have a custom launcher login? Are you creating a cracked launcher?

Define how base-editing classes is "more clean".

I don't understand why you can't just answer to the base question, however:

Why do you have a custom launcher login? Are you creating a cracked launcher?

 

Not cracked but Mojang indipendent, users that want to use it must confirm that they have a legal purchased Minecraft account but then they can use it even if the Minecraft auth servers are offline.

Because of this feature the server is in offline mode and I need a different auth method for it.

 

If someone try to login with another player usename (with wrong credentials) can see where he is in the world.

It's a symptom of low protection, they can discover where is the enemy camp, where the enemy logged out to kill him etc.

 

Define how base-editing classes is "more clean".

The ServerConfigurationManager is responsible of the logins before events or anything else, stopping the login in that moment returns in a more efficient auth, faster and with no delay to exploit.

    • I made a huge forge 1.7.10 mod pack but whenever I try to create a singleplayer world I get the error saying "A fatal error has occurred, this connection is terminated." Does anyone know what the issue could be?  Here is my fml-client-latest.log from when it crashes: https://paste.ubuntu.com/p/3rKSJSqnrX/ and here is the list of mods: https://imgur.com/a/AZifMbg

    • Made a modpack (Well Rounded Blockheads, in case the modlist on curseforge helps) and server to host it, worked fine until last night. The issue that pops up after some days being up/working is when you leave a world (singleplayer) or shutdown a server, the process hangs and jumps to 8.5gb ram used, eats up CPU usage (50-60% in taskman on a 3800x) and just sits there. If done on a single player world, the game doesnt fully crash, (e.g. if you alt+f4 buttons like save and quit, options stay in the window, are still clickable but they do nothing) Saving seems to still happen, as location/inventory updates if I restart server or client and play the world again.   If I start the currently afflicted server but dont login the server closes properly, its only once I log back in the problem occurs. Its a priv server and I dont have anyone else to test atm so Idk if its a prob with my player or players/area in general. Only recent changes in game are the additions of a pnuematicraft pressure chamber, an enchanting table, and bookshelves from builders crafts and additions.... I've been trying to get help on this all day, so ANY assistance goes a long way, even if its a way to debug this myself >~< Debug/Latest logs
    • Thanks warjort. I was afraid, that this is because they are entities. Now I know where to dig. But what about water, for example? I have checked via debug code, that there is no entity there (appropriate method return null). What is wrong with liquids?
