function closeBackpacks()
while(true) do
local tempBP = Container:GetFirst()
if(tempBP:isOpen()) then
Self.UseItem(tempBP:ID())
else
break
end
wait(600, 1500)
end
end


--[[ USAGE: openBackpacks(id1, id2, id3) ]]--

function openBackpacks(...)
Self.UseItem(Self.Backpack().id)
wait(900, 1700)
for _, input in ipairs(arg) do
local Bp = Container.GetFromIndex(input[2])
for spot = 0, Bp:ItemCount() do
local item = Bp:GetItemData(spot)
if(item.id == input[1]) then
Bp:UseItem(spot)
break
end
end
wait(900, 1700)
