Move Spears from Depot to Backpack

Hello, i need function for move spears from depot slot to backpack?
Anyone can help me?

lua code:

---      Self withdraw items

--      Withdraws a specific amount of a specific item from a specific slot to a specific container

--      @ Class Self

--      @ param slot the depot container's slot

--      @ param ... item's name or id, toContainer, amount

--      @return boolean true or false

function Self.WithdrawItems(slot, ...)

You can use this

lua code:

Self.WithdrawItems(0, {"boots of haste", "blue backpack", 100})

I think
