Describe the question
I want to open a sign GUI for a player with a given text without other players seeing the required sign.
Minecraft Verison 1.20.1
Papermc Server
My Code

`Location location = player.getLocation();
BlockPosition blockPosition = new BlockPosition(location.getBlockX(), location.getBlockY(), location.getBlockZ());

ProtocolManager protocolManager = ProtocolLibrary.getProtocolManager();

PacketContainer blockChangePacket = protocolManager.createPacket(PacketType.Play.Server.BLOCK_CHANGE);
blockChangePacket.getBlockPositionModifier().write(0, blockPosition);
blockChangePacket.getBlockData().write(0, WrappedBlockData.createData(Material.OAK_SIGN));

PacketContainer signUpdatePacket = protocolManager.createPacket(PacketType.Play.Server.TILE_ENTITY_DATA);
signUpdatePacket.getBlockPositionModifier().write(0, blockPosition);

NbtCompound compound = NbtFactory.ofCompound("");
compound.put("Text1", NbtFactory.of("String", "{\"text\":\"test1\"}"));
compound.put("Text2", NbtFactory.of("String", "{\"text\":\"test2\"}"));
compound.put("Text3", NbtFactory.of("String", "{\"text\":\"test3\"}"));
compound.put("Text4", NbtFactory.of("String", "{\"text\":\"test4\"}"));

compound.put("Color", NbtFactory.of("String", "black"));
compound.put("GlowingText", NbtFactory.of("Byte", (byte) 0));

signUpdatePacket.getNbtModifier().write(0, compound);

PacketContainer openSignEditorPacket = protocolManager.createPacket(PacketType.Play.Server.OPEN_SIGN_EDITOR);
openSignEditorPacket.getBlockPositionModifier().write(0, blockPosition);

try {
    protocolManager.sendServerPacket(player, blockChangePacket);
    protocolManager.sendServerPacket(player, signUpdatePacket);
    protocolManager.sendServerPacket(player, openSignEditorPacket);
} catch ([Exception](http://www.google.com/search?hl=en&q=allinurl%3Adocs.oracle.com+javase+docs+api+exception) e) {
    e.printStackTrace();
}`

No error message, just no text on the opened Sign. I think i have something wrong with the NBT data

I searched online and found that the 1.20 sign NBT has changed to the following

{back_text:{color:"black",has_glowing_text:0b,messages:['{"text":""}','{"text":""}','{"text":""}','{"text":""}']},front_text:{color:"black",has_glowing_text:0b,messages:['{"text":""}','{"text":""}','{"text":""}','{"text":""}']},is_waxed:0b}

So,the problem now is, how to get the right nbt data into that packet.
Can someone give me an example? Thank you!

有同样的问题，很好用：https://github.com/Rapha149/SignGUI/tree/main

I tried using it, but my sign still didn't show any messages on 1.20.1. Can you give me some help?

Had the same problem and this works great: https://github.com/Rapha149/SignGUI/tree/main

I didn't have any issues except with the .setLine() function but that can be overlooked my simply using .setLines(). This is my code with that implementation which works:

SignGUI gui = SignGUI.builder() .setLines("text1", "text2", "text3", null) .setType(Material.OAK_SIGN) .setHandler((player, result) -> { String[] linesWithoutColor = result.getLinesWithoutColor(); return List.of(//Actions on sign close); }) .build(); gui.open(p);

If you have different code try this first otherwise send your code and any errors you may have

Thank you. Now my Sign can display messages, and I have debugged it in Wrapper_ 1_ 20__ A few lines of code have been added to R1 to solve the problem with setline()
