Hide Player [1.8.9]


#ÖCT

Recommended Posts

Hi,

I've got a problem.

I wanna to make a Mod, this mod will Hide Players in the Tablist of the player, who execute the Command.

In Bukkit it is very easy, but how can I Import the Package in Minecraft Forge??

Can you say me please how the Methods call in Forge?

 

Thank you very much and sorry for my english...

 

 

 

 

I think I Must say the Client that the player Quit the Server, but he Rest on the Server...

 

That Must be possible with the player List item, but how does it works??

                         String username = hide_player.getDisplayNameString();
                        GameProfile profile = MinecraftServer.getServer().getPlayerProfileCache().getGameProfileForUsername(username);
                        UUID uuid = profile.getId();
                        
                        EntityPlayerMP remove = (EntityPlayerMP) hide_player;
                        
                         new S38PacketPlayerListItem(Action.REMOVE_PLAYER, remove);

And then you do nothing with this. What was the point?

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

First i think, I Need the UUID to choose the player.

But you got the UUID from a player object, and then did nothing with the UUID what so ever.

    • okay i've managed to fix it. looks like i made the stupidest error known to man. i hadn't installed forge to the client, which i assumed only affected the launcher which wouldn't affect me because i used a third party one. evidently not. the more you know
    • tried a fresh install of above and beyond with java 8 installed. got a popup that says "Error: Unable to access jarfile forge-1.16.5-36.2.8.jar". every good programmer knows getting a different error means you've made progress!
