The entry must be a table. Example:
lua code:
Self.WithdrawItems(FIRST_BACKPACK, {ITEM1, BACKPACK_INDEX, AMOUNT}, {ITEM2, BACKPACK_INDEX, AMOUNT}...)
The FIRST_BACKPACK is where to start searching for your items (optional), then you start the array:
{3031, 2} -- gold coin to the backpack index 2
{3031, 2, 50} -- move 50 coins instead of all
