Get tab list

[FokC]

Hello!

I was wondering if it is possible to get the player list (tab overlay) from client side.

So... Is there a way?

What do you mean exactly? Do you want a list of all players or do you want to render something when the player tab overlay is being displayed?

Well, I want the player list, but not only the players...

Some servers make some modifications to the tab menu, so there is some server information which I would like to get.

[Animefan8888]

Do you want to change what is displayed when the TabOverlay is displayed?

Or do you want to just get the information?

 

Tell me what you want to do exactly please or I might not be able to help you.

All of the fancy displaying and getting the data is done in the net.minecraft.client.gui.GuiPlayerTabOverlay class so you should look through there to get the data you want.

I actually already found out that, but I looked through the code and could not understand a thing.

I already went through a similar process of getting minecraft's code and removing what I don't need, but couldn't seem to do it with this method.

Okay what information is it that you want, the display name of the player? Please include everything.

I want all the strings displayed here (player names and the two strings, one at the top and one at the bottom, assuming they are "special")

[Animefan8888]

I assume you are going to do something with this can you explain what?

And tell me what you have access to ATM.

I am working on server detection for several servers.

Some servers use scoreboards, which were quite easy to figure out from the game code.

Some servers use welcome messages.

Some servers use Tab Player List information, which I have yet to find a way to get the information from the tab menu.

 

Basically, I've made few attempts at understanding the game code, but because the variable names are not useful and there are no comments, I pretty much have nothing right now (besides the original game code)

[Animefan8888]

Server Detection? Like detecting when the player is on the server or when the player is pressing tab?

I need to detect a certain server.

Because some big networks use proxy servers, I can't simply use ClientConnectToServerEvent (or whatever).

The detection needs to be done from information that the client already have, and not relay on events

Again, I have many ways determining which server the player is on.

I know when he is on, and I know what IP he used to connect to that server.

But, lets say I made up a proxy server on my local machine, that will connect me to "mc.hypixel.net".

The minecraft client won't know that it was redirected to "mc.hypixel.net", and it will still think it is connected to "localhost".

Because of that reason, I need ways to know what server the player is on without using login events and connection information.

I'm not sure that I understand what you are wanting to do besides getting the PlayerTabInformation. So let me ask what is your main goal, what are you going to do with this information.

I'm not sure that I understand what you are wanting to do besides getting the PlayerTabInformation. So let me ask what is your main goal, what are you going to do with this information.

I just need to have a piece of code that will yield me a string list, containing the information from the tab menu.

If I'll be able to get there (with help or on my own), I'll be able to break down the info and continue on my own.

 

I understand java programming and game programming very well (I've been studying for more than 4 years), but I'm not that great at analyzing code without meaningful variable names or without comments. If I would be able to understand the minecraft code by myself I wouldn't be here, but I'm here because I just cant seem to find a way to read information from the tab menu.

[FokC]

From your tiny screenshot I am guessing you mean the header and footer for the player list.

You can get those using

Minecraft#ingameGUI.getTabList().header

/

footer

. These fields are private so you will need to use reflection to access them.

I do want to access them, but also access the entire tab menu
