Nametag method

[itsfsnow]

Excuse not being in the correct place, I don't think there is but this seems most appropiate. SpigotMC doesn't really support 1.7 so I couldn't get anything there really.

I need a method like this one, but for 1.7

        sendPacket(toSendTo, teamPacket(player, prefix, suffix, teamAction));

        packet = new PacketPlayOutScoreboardTeam();

        return packet;
    }

    private static void addPlayer(Player player) {
        setField("g", Collections.singleton(player.getName()));
    }

    private static String Color(String input) {
        return ChatColor.translateAlternateColorCodes('&', input);
    }

    private static void sendPacket(Player player, PacketPlayOutScoreboardTeam packet) {
        ((CraftPlayer) player).getHandle().playerConnection.sendPacket(packet);
    }

    private static void setField(String field, Object value) {
        try {
            Field f = packet.getClass().getDeclaredField(field);
            f.setAccessible(true);
            f.set(packet, value);
            f.setAccessible(false);
        } catch (Exception exception) {
            exception.printStackTrace();
        }

    }
   
}

When I try that it just crashes the player

^ The reason why I need to do it using packets is because I want it so 2 player can view a player's name tag differentlyt

If you're a decent developer you'll understand how to do what you want

I read through it and I can't see how you set a tag for someone per person (e.g. one player sees red when they look at a player, and one person sees green)

You use the player's scoreboards

Would this not conflict with a scoreboard plugin? Will I need to have different scoreboards per person & store it in a hashmap and access that and edit it

Make your own scoreboard plugin or somehow hook into it

Most scoreboard plugins have an individual scoreboard object for each user

I imported the source code into my file, but am getting errors for example 'Nametag.getInstance()' getInstance() isn't defined. Do I have to manually add these or have I done something wrong, I haven't gotten errors before importing other than packet errors which is expected cross version[DOUBLEPOST=1564944122][/DOUBLEPOST]& I did install lombok btw

Have you added lombok to your dependencies

Have you added lombok to your dependencies

Yeah I have, got it from here https://projectlombok.org/download

That's your IDE issue not my project

Yeah apparently I need to install lombok as well rather than add it as a dependency. Thanks for the help though! Your class looks like just what I need.
