    // armor slots) both PacketPlayOutSetSlot and setItem() places the items in the player's inventory the same way.
    // Index 9 starts at the upper left corner of the inventory and moves to the right as it increases. When it
    // reaches the end of the line it goes back to the left side of the new line in the inventory. Basically, it
    // follows the path your eyes would follow as you read a book.
    //
    // The player's hotbar is indexed 0-8 in setItem(). The order goes: 0-8 hotbar, 9-35 normal inventory, 36 boots,
    // 37 leggings, 38 chestplate, and 39 helmet. For indexes > 39 an ArrayIndexOutOfBoundsException will be thrown.
    //
    // PacketPlayOutSetSlot works very differently. Slots 0-8 are as follows: 0 crafting output, 1-4 crafting input,
    // 5 helmet, 6 chestplate, 7 leggings, and 8 boots. Then, 9-35 work exactly the same as setItem(). The hotbar
    // for PacketPlayOutSetSlot starts at index 36, and continues to index 44. Items placed where index is < 0 or
    // > 44 have no action. Basically, the upper part of the player's inventory (crafting area and armor slots) is
    // the first "row" of 9 slots for PacketPlayOutSetSlot. From there the rows work as normal, from left to right
    // all the way down, including the hotbar.
    //
    // With this in mind, we have to modify the index we give PacketPlayOutSetSlot to match the index we intended
    // with setItem(). First, if the index is 0-8, we need to add 36, or 4 rows worth of slots, to the index. This
    // will push the item down to the correct spot in the hotbar.
    //
    // Now when index is > 35 (if index > 39 an ArrayIndexOutOfBoundsException will be thrown, so we need not worry
    // about it) then we need to reset the index, and then count backwards  from the "top" of the inventory. That is
    // to say, we first find (index - 36), which will give us the index required for the armor slots. Now, we need
    // to reverse the order of the index from 8. That means we need 0 to correspond to 8, 1 to correspond to 7,
    // 2 to correspond to 6, and 3 to correspond to 5. We do this simply by taking the result of (index - 36) and
    // subtracting that value from 8.
