What you better Make Arrows
Arrows are pretty easy to acquire.
Luckily, these resources aren’t especially hard to get.

You get flint from mining gravel, which is easy to find underground.
Gather feathers from killing chickens or parrots, which can drop up to two feathers.
Place your Crafting Table, and open up the crafting interface.

What Can You Craft With Arrows?
The main thing you’re free to craft with arrows is a tipped arrow.
Tipped arrows are, essentially, potions in arrow form.

Together, these ingredients will create eight tipped arrows.
At the Crafting Table interface, place your potion in the middle, and then surround it with arrows.
In most cases, though, these arrows are not available on either platform.

However, you may not even need them.
As long as you have one arrow in your inventory, it’s possible for you to shoot forever.
