Issue with custom GUI

[Reyzerbit]

Hey folks!

So I have been working on a port of the classic mod Minecraft Comes Alive into modern forge versions as it hasn't been updated since 1.12.

Anyways, I am attempting to send a SimpleChannel message when a button is clicked in the GUI, in order to alert the server that the baby's name is being changed. Here's the error I am getting whenever I press the button:

---- Minecraft Crash Report ----

    	INSTANCE.registerMessage(NETWORK_INDEX++, CareerResponse.class, CareerResponse::encode, CareerResponse::decode, MessageHandler.Client::handle, Optional.of(PLAY_TO_CLIENT));
        //INSTANCE.registerMessage(CareerResponseHandler.class, CareerResponse.class, 3, Side.CLIENT);
        
    	INSTANCE.registerMessage(NETWORK_INDEX++, InventoryResponse.class, InventoryResponse::encode, InventoryResponse::decode, MessageHandler.Client::handle, Optional.of(PLAY_TO_CLIENT));
        //INSTANCE.registerMessage(InventoryResponseHandler.class, InventoryResponse.class, 6, Side.CLIENT);
        
    	INSTANCE.registerMessage(NETWORK_INDEX++, SavedVillagersResponse.class, SavedVillagersResponse::encode, SavedVillagersResponse::decode, MessageHandler.Client::handle, Optional.of(PLAY_TO_CLIENT));
        //INSTANCE.registerMessage(SavedVillagersResponseHandler.class, SavedVillagersResponse.class, 8, Side.CLIENT);
        
    	INSTANCE.registerMessage(NETWORK_INDEX++, GetFamilyResponse.class, GetFamilyResponse::encode, GetFamilyResponse::decode, MessageHandler.Client::handle, Optional.of(PLAY_TO_CLIENT));
        //INSTANCE.registerMessage(GetFamilyResponseHandler.class, GetFamilyResponse.class, 13, Side.CLIENT);
        
    }

}

Message Handler, which is called on message recieved:

public static void handle(BabyName msg, Supplier<NetworkEvent.Context> context) {
  
  context.get().enqueueWork(() -> ServerHandler.processMessage(msg, context.get().getSender()));
  
  context.get().setPacketHandled(true);
		    
}

And finally: the specific handler itself:

protected static void processMessage(BabyName msg, ServerPlayerEntity player) {

	ItemStack stack = player.inventory.getSelected();

	if (stack.getItem() instanceof Baby) {

		CompoundNBT nbt = stack.serializeNBT();
		nbt.putString("name", msg.getBabyName());
		stack.deserializeNBT(nbt);

	}

	return;
		
}

I'm trying to figure out what is wrong with this. I can't seem to figure out what's going wrong, and I've been trying things and googling help for almost 3 days now.

 

Any advice would be appreciated!

 

Thanks!

What do you mean?

I'm not sure what he meant but could you show what code the 76th line of NameBabyScreen is

Yup! It's actually the line 

 Network.INSTANCE.sendToServer(new BabyName(babyNameTextField.getValue().trim()));

from the Overrided init. I'll edit it with a comment so you can see.

How do you register the onCommonSetupEvent event handler? I am guessing you aren't, so it is never called.

I knew I forgot something! This was the issue haha. I always forget to add the listener, for some reason my brain always wants to assume that the @EventSubscriber annotation is enough.

 

Thank you!
