Development Assistance Header, Footer and Titles 1.8 coding

Hey Guys,
I want to know how to do titles and tab header and footers!
I have no idea how to do this so any help will be appreciated!
Thanks,

The titles can be done with the packet PacketPlayOutTitle and the header/footer with PacketPlayOutPlayerListHeaderFooter. e.g.:

Code:

PacketPlayOutTitle times = new PacketPlayOutTitle(<fadeIn>, <display>, <fadeout>); //The time the title is displayed in ticks
PacketPlayOutTitle title = new PacketPlayOutTitle(EnumTitleAction.TITLE, ChatSerializer.a("\"§6Cookies!\""));
PacketPlayOutTitle subtitle = new PacketPlayOutTitle(EnumTitleAction.SUBTITLE, ChatSerializer.a("\"§cThey're delicious!\""));
for(Packet packet : new Packet[] {times, title, subtitle}) {
    ((CraftPlayer) <playertosend>).getHandle().playerConnection.sendPacket(packet);
}
PacketPlayOutPlayerListHeaderFooter headerfooter = new PacketPlayOutPlayerListHeaderFooter();
try {
    Field header = headerfooter.getClass().getDeclaredField("a");
    Field footer = headerfooter.getClass().getDeclaredField("b");
    header.setAccessible(true);
    footer.setAccessible(true);
    header.set(headerfooter, ChatSerializer.a("\"§3Welcome to a server!\""));
    footer.set(headerfooter, ChatSerializer.a("\"§aI'm a footer!\""));
} catch (Exception ex) {
    ex.printStackTrace();
}
((CraftPlayer) <playertosend>).getHandle().playerConnection.sendPacket(headerfooter);

 

@megamichiel Would i put that in a Join Listener and also does that work with 1.8.3?

 

@WingedMLGPro
You can put it anywhere, and the titles and tab list headers/footers are especially for MC 1.8+. But if you do put it in the join listener, you have to put a little delay or the player won't recieve the packet properly

 

@megamichiel when i do a command, it doesnt work! Here is my code:

Code:

package me.benkea.Test;

import net.minecraft.server.v1_8_R2.IChatBaseComponent;
import net.minecraft.server.v1_8_R2.Packet;
import net.minecraft.server.v1_8_R2.PacketPlayOutPlayerListHeaderFooter;
import net.minecraft.server.v1_8_R2.PacketPlayOutTitle;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.craftbukkit.v1_8_R2.entity.CraftPlayer;
import org.bukkit.entity.Player;

public class TestCmd implements CommandExecutor {
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {

        Player p = (Player)sender;

        if (cmd.getName().equalsIgnoreCase("tester")){
            p.sendMessage("OK!");
            PacketPlayOutTitle times = new PacketPlayOutTitle(5, 60, 5); //The time the title is displayed in ticks
            PacketPlayOutTitle title = new PacketPlayOutTitle(PacketPlayOutTitle.EnumTitleAction.TITLE, IChatBaseComponent.ChatSerializer.a("\"§6Cookies!\""));
            PacketPlayOutTitle subtitle = new PacketPlayOutTitle(PacketPlayOutTitle.EnumTitleAction.SUBTITLE, IChatBaseComponent.ChatSerializer.a("\"§cThey're delicious!\""));
            for(Packet packet : new Packet[] {times, title, subtitle}) {
                ((CraftPlayer) p).getHandle().playerConnection.sendPacket(packet);
            }
            PacketPlayOutPlayerListHeaderFooter headerfooter = new PacketPlayOutPlayerListHeaderFooter();
            try {
                Field header = headerfooter.getClass().getDeclaredField("a");
                Field footer = headerfooter.getClass().getDeclaredField("b");
                header.setAccessible(true);
                footer.setAccessible(true);
                header.set(headerfooter, IChatBaseComponent.ChatSerializer.a("\"§3Welcome to a server!\""));
                footer.set(headerfooter, IChatBaseComponent.ChatSerializer.a("\"§aI'm a footer!\""));
            } catch (Exception ex) {
                ex.printStackTrace();
            }
            ((CraftPlayer) p).getHandle().playerConnection.sendPacket(headerfooter);
        }
        return true;
    }
}

 

@WingedMLGPro
Does it send the message "OK!"?

 

@megamichiel No, it does the thing where in white it says /tester

 

@WingedMLGPro
In your onEnable call "getCommand(<commandname).setExecutor(<command class>)", so bukkit knows which class handles the execution of the command

 

@megamichiel I did that! It just doesnt work for some reason

 

@megamichiel Do you want me too send you my main and command again?

@megamichiel I figured out it was the code you sent me at the top that was bugging it.
I dont think that code works!

@WingedMLGPro
No matter how many errors occur, everything that happens before it gets performed normally, so there's something not properly done if you're still seeing the white command message.
