Based on the log I can assume that this happened when one of my Ship entities loaded in the game. Of course though it doesn't tell me where the problem actually occurred >.<  . Any ideas for how I can fix this?

I suggest you set a breakpoint where the exception is thrown from the 

S3FPacketCustomPayload

constructor.

 

If the packet is a wrapper for an 

IMessage

, the 

S3FPacketCustomPayload#channel

field will be the name of the 

SimpleNetworkWrapper

that sent it and the first byte in the 

S3FPacketCustomPayload#data

field (

ByteBuf#getByte

) should be the discriminator of the 

IMessage

.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

Something you are sending is over 1MB, we don't know what due to how to things are designed, but as the others said you can use your IDE to track down what is being sent to see why the game things you need so much data.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

      Launcher using wrong constructor

      By matwaua · Posted

      I am following a tutorial for modding minecraft 1.20.1, and while running the mod with the minecraft of the idea, no errors was present but, when I switched to real minecraft, it started to want a default constructor "public ZeroToAutomation()" instead of the one recomended by the video "public ZeroToAutomation(FMLJavaModLoadingContext context) {...}", and I can't use the default constructor because I need the FMLJavaModLoadingContext to register the blocks and items.   The problem is at: "net/myself/zerotoautomation/ZeroToAutomation.java" the file contains the default constructor, "Logger"s, and the code for the mod the defaut constructor was added after an error requesting it the Loggers was used to see which methods/constructors was used by the Launcher   things that I tried to fix the issue: remove the default constructor, but an error appeared "net.myself.zerotoautomation.ZeroToAutomation.<init>()", and nothing else on the class runs adding an "public static void init()" method, but it changed nothing   The mod files: https://github.com/Matwaua/Zero_To_Automation/tree/not-finished
