// InventoryTransaction is a packet sent by the client. It essentially exists out of multiple sub-packets,

// directly relate to the inventory, others relate to interaction with the world, that could potentially
// result in a change in the inventory.

// in it.
// LegacyRequestID ties in with the ItemStackResponse packet. If this field is non-0, the server should
// respond with an ItemStackResponse packet. Some inventory actions such as dropping an item out of the
// hotbar are still one using this packet, and the ItemStackResponse packet needs to tie in with it.
