[1.15.2] Receive packet event?

[RobinCirex]

Hey, I'm trying to track the packets received. I can't find an event for that, so I tried overwriting the NetworkManager of Minecraft#getConnection

The mod is a clientside mod. 

public void onSetup(FMLCommonSetupEvent event) {
		ObfuscationReflectionHelper.setPrivateValue(ClientPlayNetHandler.class, Minecraft.getInstance().getConnection(),
				new CustomNetworkHandler(PacketDirection.CLIENTBOUND), "field_147371_a");
	}

package me.cirex.ditzydisplay.clientchannel;

import net.minecraft.network.IPacket;
import net.minecraft.network.NetworkManager;
import net.minecraft.network.PacketDirection;

public class CustomNetworkHandler extends NetworkManager {

	public CustomNetworkHandler(PacketDirection packetDirection) {
		super(packetDirection);
		System.out.println("test");
	}

	@Override
	public void sendPacket(IPacket<?> packetIn) {
		System.out.println("test");
		super.sendPacket(packetIn);
	}

	@Override
	public void tick() {
		super.tick();
		System.out.println("test");
	}
}

This is my code. I don't get an errror, but I don't get any sysouts either

If it's a client-only mod, you should definitely put this in the ClientSetupEvent, so you don't run the risk of strange missing class errors. There are also fields in the NetworkManager class that don't get initialized in the constructor. You may want to either scrape all the fields from the original instance of NetworkManager and copy them to your custom class or try to do something similar to the ClientPlayNetHandler.

Oh yea, I had it in the ClientSetupEvent, I changed it for some reason. I'll try that out, will get back if I still need help

What are you trying to do? Messing with the network connection is almost always a bad idea.

Well, basically I'm trying to build up a connection between spigot and forge. I don't want to manipulate the packets or anything, just listen to them. 

I didn't figure it out yet, would be nice if you helped me

Forge can connect to vanilla servers just fine. Since spigot acts as a vanilla server, no further action needs to be taken.

 

If that does not answer your question, you need to elaborate.

This doesn‘t answer my question. Basically I have a mod and if it gets specific packets its supposed to render specific models. So I want to make custom packets that the mod is listening to
