Here is my playlist detailing my development of the datapack

The datapack is still in Beta, and will probably be that way for a long time

However, you can still enjoy the many many systems put into place.

Upon loading this datapack, you will be given

-the Slot parts for Weapons, Bows, and Arrows.
-Paraglider
-Satchel (secretly a spyglass)
-Shiekah Slate

You can get every item in the game by typing in /function botwweapons:giveeverything
You can uninstall and remove the data storage and scoreboard with /function botwphysics:uninstall

What is added?
Yes, literally everything

Weapons
-Every one-handed weapon from the game
  Including:
  -The basic swords
  -The elemental swords
  -Magic Rods
  -Boomerangs
  -The Ancient weapons
  -The other weird stuff
-Every Shield
  -Along with shield surfing
-Every Spear
-Every Bow
-All special arrows

Physics
-The Stamina Wheel
  Including:
  -Climbing
  -Sprinting
  -Not Swimming (that would be terrible)
-The entire inventory system from the base game
-The Paraglider
-The Shiekah Slate with all of its runes

Mobs
-Bokoblins, Moblins, and Guardians naturally spawn
  -A very incomplete section.
    -Guardians kill you easily, but are still somewhat buggy
    -Bokoblins and Moblins are just zombies, but with names, items, and health
~Eventually every monster from the base game will replace every vanilla minecraft mob~

Worldgen
~Shrines, Bokocamps, and the Skull camps will be added. Worldgen changes too much right now, so I haven't started yet.
In Shrines you will obtain Spirit Orbs, to then use at vanilla villages to increase your health or stamina wheel.

So what do these do?

Weapons
Swords/spears from this datapack are kept in a specific slot, colored blue. When you hold the blue square, you can place your weapons in your unlocked inventory slots. There it is stored. You can then keep a sword in your first hotbar slot, so you can access your weapons at any time.

~This is how each of the slots work. Weapons, Bows, Arrows, and Everything Else (the satchel) each have their own one of these.~

Swords deal the same damage from the base game, to correspond with the custom mobs having the same health as the base game.
Boomerangs and Spears are dropped/thrown to use their special ability.
Magic Rods are right click weapons
Special Arrows you keep in your hotbar to use with a bow

Physics
Stamina wheel works just like the game. When you hold your satchel, shiekah slate, or nothing, you automatically sprint faster.
Climbing works by facing a wall, and shifting/sneaking.

Paragliding works from you having the item in your inventory (holding the satchel), jumping, and shifting while in the air.
A saddle with the paraglider will float in front of you, and you have to right click the saddle to use the paraglider.
  -You will automatically glide forward and down, and it travels where you look.

Shiekah Slate works by right clicking to use the rune, and then putting the item in your offhand (or pressing F) to cycle to different runes

Shield Surfing works the exact same way, except you have to have a shield in your offhand, and the paraglider in your mainhand
Grab the saddle, and you will automatically travel forward along the ground. You can't gain altitude, only lose it.
When you want to exit, you can grab your shield off of the totally-not-an-armorstand that is left.
