To start, you will need a world with cheats enabled to use this datapack. You can create one or using an already existing world (in 1.20.5/1.20.6).

1. Extract the folder (the extracted folder should contain the pack.mcmeta file).
2. Copy the folder that CONTAINS the pack.mcmeta file. It should be named something like "Command Block Survival Datapack."
3. Open Minecraft and select the world you want to add the datapack to (don't open it!).
4. Click "Edit" and then "Open World Folder". You should see a folder named "datapacks".
5. Open the datapacks folder and paste the folder you copied into here. The folder order should look something like this "NewWorld3/datapacks/Command Block Survival Datapack/pack.mcmeta"
6. If it does open your world and run the command "/reload" in the chat bar. You should see a loading message from the pack.
7. Now you're good to go! If you ever want to turn the datapack features off, use the command "/function cb_survival:config" and click the appropriate buttons.



Heads-Up/Warnings:

1. When interacting with a structure block, due to a Minecraft bug, you will have to deselect the creative item on your hotbar to go back into survival mode. Make sure you don't forget to switch back.
2. When placing a block, if the block quickly disappears, don't worry. It only takes an item if the block was successfully placed.

In case the images aren't clear enough:

Command Block (Orange): Upside down "U" of regular terracotta in a crafting table, redstone block in middle, iron door at the bottom.
Command Block (Purple): Same as above, but with blue terracotta (looks purple).
Command Block (Blue-Green): Same as above but with alternating blue and lime terracotta. Works both ways.
Command Block Minecart: Command block on top of minecart.
Structure Block: Obsidian in four corners, command block in the center and purpur blocks in the other four slots.
Barrier Block: Cook obsidian in furnace
Structure Void (kinda like tiny barrier block that can be used with structure blocks): Cook a barrier block in a furnace.

To make teleporters:
  1. Make an orange command block and place it.
  2. Edit the command block by holding any type of command block in your hand and right clicking the block you placed.
  3. Enter "tp @p x y z" replacing x, y, and z with the coords of where you want to go.
  4. Place a pressure plate or button near the command block so you can activate it.
  5. Don't forget to make one that teleports you back. :)

To have a pet:
  1. Name any mob (if it is a hostile mob do steps 1a through-1c)
    1a. Copy the commands inside the quotes: "/team add friend"
    1b. "/team join friend @p"
    1c. Replace the $ with the name of your mob: "/team join friend @e[​name=$]"
  2. Make a repeating (purple) command block and place it somewhere near spawn.
  3. Set it to the setting, "Needs Redstone" and put a lever next to it.
  4. Enter the command, "execute as @p at @s run tp @e[​name=$,distance=12..] @p" replacing $ with the name of your mob again.
  5. Turn the lever on and the mob should teleport to you when it gets too far away, like a cat or a dog. Enjoy! :)

To make a command block flying machine:
  This one is more complicated. But if you're willing to learn there are tutorials for this and more command block creations on youtube from a variety of creators. The possibilities are massive! :)
  P.S. If you want a hint you'll need the clone command and the tp command or structure blocks if you're fancy. :)
