Is this possible make in an objective?

Hello there, this is my first time posting here.

I wanted to know if this is possible or not, what I want to do, it's if I can remove the score of a player.
I mean, I want to do invisible the score of a specific player, they cannot see mine, but I can see their, by the way I'm talking in a display slot as list, I'm posting this because I don't know if is possible... but well

Example (open) Example (close)

This is what I meant

 

Yes I do think that there a way of doing this.
You can look at this packets and figure out how to deal with it

• PacketPlayOutScoreboardDisplayObjective
• PacketPlayOutScoreboardObjective
• PacketPlayOutScoreboardScore

I think this will help you a bit.

 

And how can I use packets? with protocolLib? or is there another way for do it?
If there's a tutorial how to use packets, tell me please.

by the way, thanks for your help.

 

Dear @!PoKu,

I will try to make it myself. And If I'm done I will directly send you the code for the scoreboard.

 

That'd be too much help!

Really thanks for your help again.

 

Sorry, I've tried every way I could think of but if you submit a scoreboard, every futured player will be registered in the tablist. My only possible option I could think of which is not what you want, is to display the scoreboard list only for the players who must see the other scores, or you can make a prefix such as [%score%] PlayerName e.g ([4] !PoKu).
But that is what I got for you. btw I was sick this entire week, Sorry for the late reply.

If you need some further help with this, I can take my time for you to create the best solution.

 

It's okay dude, don't worry, really thanks you very much for your help.
