I get an

when using the open function, could you recode? Thanks!

I doubt nisovin is going to do it anytime soon

This actually works great. At the moment I'm developing an implementation of this using NMS packets.
For fun and for not using ProtocolLib

CTRL · Mar 24, 2016

This is being posted for random wanderers from google (like me yesterday)

1.7 and 1.9 implementation using NMS (no protocollib!) is available in my plugin's repo. https://github.com/MarcinWieczorek/...n/java/co/marcin/novaguilds/impl/util/signgui

You also need Reflections class and interfaces, find it all there on github.
enjoy!

    public interface SignGUIListener {

Usage:

Code:

public static void openSign(Player p) {    
        Main.getSignGUI().open(p, new String[] { "test0", "test1", "test2", "test3" }, new SignGUI.SignGUIListener() {
            @Override
            public void onSignDone(Player player, String[] lines) {
                System.out.println(lines[0]);
            }
        });
    }

I hope this helps you

This is a 2.5 years old thread, it is pretty much outdated

can you give me Libraries list, thank you

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

CTRL · Mar 25, 2016

Libraries:
SpigotAPI (BukkitAPI)
JDK (7 at least)

It works for 1.7, 1.8, 1.9. Why didn't you read my post above? I said there I didn't use any additional libraries.
