This module will shoot a bow to yourself silently

module_manager.register('Bow', bow)

player.send_packet(0x09, i) swaps your hand to the bow hotbar slot

player.send_packet(0x08, i) starts using the item in that slot

player.send_packet(0x07) releases the item

player.send_packet(0x09, player.held_item_slot()) switches back to the item you actually have on hand
