[1.10.2]Suggestions on how to rework this to reduce packet size

[The_Fireplace]

So, I send a packet that contains one NBTTagCompound containing a lot of data(Mostly inventories within a tile entity). Unfortunately, it seems to be too large, since I get the following crash upon sending.

My question to you is, how do you suggest I redesign the system to reduce the packet size?

My current way of doing things involves sending the packet to the client just before the GUI opens. This packet contains all of the entity's data, including inventory, which the client needs or else it will crash upon opening the GUI.

The creation of the NBT Tag Compound

The packet

 

If anyone knows of a way to reduce packet size or simply split this in to as many smaller packets as needed, it would be greatly appreciated.

I would suggest looking at the code for writing a NBTTagCompound to a ByteBuf and find the limitation or you could just send multiple packets for each inventory.

This exception is caused by a client-to-server message (which Forge limits to a single CPacketCustomPayload, i.e. 32,767 bytes), not a server-to-client message.(which Forge splits into a a maximum of 255 SPacketCustomPayloads, i.e. 267,366,480 bytes).

 

Do you need to send all of that data to the server at once? Can you send individual parts that have changed, possibly through the Container?

 

You shouldn't be storing mutable game data in a field of your @Mod class (Caterpillar#mainContainers), since it's shared between logical sides in single player. You should be using World Capabilities or World Saved Data (if storing the data directly in the TileEntity isn't an option).

 

Iterating through a server's World's to find a block at a specific position is very unreliable, what happens when two dimensions have a drill at the same position?

Ah, I see. Thanks for the explanation, it should be somewhat easy to fix now, since the client shouldn't have any reason in this mod to need to send that much data to the server.

 

Thanks for the suggestions, I will work on them today. You've pointed out several problems and ways to fix them that I wouldn't have caught. As for the why of all of that bad design, that was the original author's doing, and I have been working on fixing it for a while now.
