[1.15.2] SimpleImpl crash when on Dedicated Server

Recommended Posts

Hello!
I'm trying to set up a GUI with buttons, and to communicate button changes, I'm using a SimpleChannel. This works flawlessly on client, however, on server, I experience a crash on the server related to missing classes. I assume this is due to referencing a class only present in Client, however I do not know where I do this.

 

Class for handling packets.

https://github.com/HaydenBelanger/assembly_line_machines/blob/development/src/main/java/me/haydenb/assemblylinemachines/packets/HashPacketImpl.java

 

Method for sending the packet to the channel.
https://github.com/HaydenBelanger/assembly_line_machines/blob/development/src/main/java/me/haydenb/assemblylinemachines/block/energy/BlockBasicBatteryCell.java#L327-L341

 

Registering the channels.

I would love a point in the right direction as I don't see what could be the problem with this.

So is maxLength the length of the String being packet-ified?

It says maxLength means the string read from the packet can not be longer than it, readString() passed in 32767.

   /**
    * Reads a string from this buffer. Expected parameter is maximum allowed string length. Will throw IOException if
    * string length exceeds this value!
    */

Considering readString() legitimately passes to readString(32767), that is a very... peculiar sided restriction. Thank you very much for helping me figure it out!

It's not peculiar if you understand how the dist-only methods come to be. They are most likely optimized away by Mojang's obfuscator (or some other step in their build process), not removed by hand.

If a method is not used on the server, it is not included.

That makes a lot of sense, actually.
