This will require you to make two separate items: the weapon itself and the bullet it fires. We will start with our bullet. Create a new item mod element and give it a name that you will remember as your bullet/arrow/projectile.
Create your texture for your bullet and apply it.
After this, you don’t need to add anything else to your bullet item. Complete all the steps for creating the item, the default settings should be fine. Next, we need to make the item that shoots it.
