Handling vanilla packet

[DmitryLovin]

Is there a way to handle vanilla packet (SSetSlotPacket to be exact).

Part of the vanilla handler do this:

itemstack.setAnimationsToGo(5);

but only if item in hotbar slots, I want to do it for any item.

 

I know the way to do it without packets, just check for changing in inventory every tick, but I don't think it is a good idea (don't know why) and trying to find another way.

I want to render animation for recently chenged items.

I only need client player inventory, so it might help, thank you.
