The method getSlot() is undefined for the type EntityEquipmentUpdateS2CPacket

[XfedeX]

This is the code:

	@Override
	public void onReceivedPacket(PacketInputEvent event)
	{
		if(event.getPacket() instanceof EntityEquipmentUpdateS2CPacket)
		{
			EntityEquipmentUpdateS2CPacket packet = (EntityEquipmentUpdateS2CPacket)event.getPacket();
			Entity entity = MC.world.getEntityById(packet.getId());

			if(entity == null) return;
			if(!(entity instanceof PlayerEntity)) return;
			if(murderers.contains(entity)) return;

			if(packet.getSlot() != EquipmentSlot.MAINHAND) return;
			Item item = (packet).getStack().getItem();
			if(!knifeItems.contains(item)) return;

			PlayerEntity murderer = (PlayerEntity)entity;
			murderers.add(murderer);
			ChatUtils.message(murderer.getName().asString() + " is a murderer. (knife: " + item.getName().asString()  + ")");
		}
		else if(event.getPacket() instanceof PlayerRespawnS2CPacket)
		{
			murderers.clear();
		}
	}

And these are errors:

The method getSlot() is undefined for the type EntityEquipmentUpdateS2CPacket
The method getStack() is undefined for the type EntityEquipmentUpdateS2CPacket

If there no longer are getSlot and getStack, how to get the item on hand?

Ok i somewhat figured out: I need to make something like
packet.getEquipmentList()
But I don't know how to get only EquipmentSlot and not all the list.
Now i get error:

Incompatible operand types List<Pair<EquipmentSlot,ItemStack>> and EquipmentSlot
with code:
if(packet.getEquipmentList() != EquipmentSlot.MAINHAND) return;

OK now i changed to if(packet.getEquipmentList().Pair.getFirst != EquipmentSlot.MAINHAND) return;

but I get error Pair cannot be resolved or is not a field
Of course I have imported com.mojang.datafixers.util.Pair; !

You need to iterate the list to check each pair. This is basic programming.

for (Pair<EquipmentSlot,ItemStack> pair : packet.getEquipmentList()) {
  if(pair.getFirst() != EquipmentSlot.MAINHAND) // do your stuff
}
