[1.16.5] How to send the instruction to open the "written book" GUI from the Server-Side (with text)


Recommended Posts

If anyone can help me with this . I'm creating a command to open the GUI of a book.
Supposedly this should work. But it doesn't do anything. Can somebody help me?
Forge 1.16.5 - Server Side Mod


                        .executes(context -> {
                            ItemStack book = new ItemStack(Items.WRITTEN_BOOK);

                            CompoundNBT nbt = new CompoundNBT();

                            ListNBT pages = new ListNBT();

                            pages.add(StringNBT.valueOf("{\"text\":\"Hello World\"}"));

                            nbt.putString("author", "Steve");
                            nbt.putString("title", "my_book");
                            nbt.put("pages", pages);
                            nbt.putByte("resolved", (byte) 1);

                            context.getSource().getPlayerOrException().openItemGui(book, Hand.MAIN_HAND);
                            return 1;

I have tried with "SOpenBookWindowPacket" but it only sends the instruction to open a book that the user has in their hand.

ServerPlayerEntity serverPlayerEntity = context.getSource().getPlayerOrException();
                            SOpenBookWindowPacket packet = new SOpenBookWindowPacket(serverPlayerEntity.getUsedItemHand());

The idea is that this mod is an information command for the user. You should not give a book to the user and have them read it. I have seen the Spigot documentation and have found some examples of how this is done on servers.

PacketPlayOutCustomPayload packet = new PacketPlayOutCustomPayload("MC|BOpen", new PacketDataSerializer(buf));

Is there a way to do this with Forge Server Side? I've been dealing with this for 2 days and I can't find a solution. I've searched on Google and can't find anything.
