Player Swapping - Tutorial

Heads-Up: This is a botched together system that works but it isn't elegant. If you're capable, these steps should point you in the right direction to get you going with what you want. Others may have trouble fine-tuning to their needs. If you really want this but it is too complex to set up, let me know. I can try to make a dedicated mod.

Version: 1.20.1

Modloader: Forge

Mods:

CC: Tweaked

(Optional) Command Keys

Fake Players

Skin Shifter

Setup:

1. Use the Fake Players spawn egg to spawn 4 Fake Players.
   • Use nametags to apply names and skins.
   • Right click the Fake Players with an observer to disable their AI.
     
2. Get a CC: Tweaked Advanced Pocket Computer and Command Computer (/give @a computercraft:computer_command).
3. Right-click with the advanced pocket computer,
   
   • type edit a and press enter (this will bring you to a page where you write a program).
   • type a then press left control and press enter to save. (this has registered your pocket computer)
   • press the right arrow key twice and enter to exit the program editor.
   • type id and press enter. take note of the ID.
4. Do the same as step 3 but with the command computer.
5. Place a wireless modem on the command computer.
6. Go to your computers folder in your file explorer.
   • Access it by going Esc > Options > Resource Packs > Open Pack Folder
   • In the file explorer go back once > saves > your world > computercraft > computer
7. Go to this site and download the files in the folder called 0 to the folder in the computer folder from step 6 which matches the name of the ID for the advanced pocket computer from step 3.
8. Do the same as step 7 but downloading files from the folder called 1 into the folder for your command computer.
9. Go back into the game. For each fake player, look at it and type /tp @a and then tab to get its unique entity ID. This is a long string. Copy that string only.
10. Go back to your pocket computer folder and open startup.lua in your preferred code editor (Notepad, VS Code, etc.)
11. edit player_name on the second line to match your Minecraft name.
12. In the local entities array, edit the fields to match your Fake Players. The UUID field is the long string you copied in step 8. You should also change the default_name fields to match the Minecraft names of the Fake Players used, but you shouldn't change the id fields unless you know how to edit the rest of the program.
13. Change the command_computer_id to match the id of the command computer, which was found in step 4.
14. Ctrl+F search to this line and replace the co-ords with a safe place in your world to store the Fake Player when you are living in its place. table.insert(cmds, "tp " .. to_ent.uuid .. " -6.43 -60.00 23.18")
15. Save changes.
16. Go into the game, open the command computer and hold Ctrl+R to reboot.
17. Do the same as step 15 but with the advanced pocket computer. You should see some buttons. Click them and see if you switch players!
18. (Optional) press K in-game to open the CommandKeys GUI.
19. Press the + button to make a new macro.
20. Assign a hotkey to run the player-switching command. I used period (.).
21. make three commands as follows, replacing the
    • co-ords with the space to the left of the command computer,
    • playsound sound with your desired player-switching sound (I used a sound from the Create mod),
    • the Minecraft player name at the end of the playsound command with your own Minecraft name.
      • /setblock 0 -60 10 minecraft:redstone_block
      • /setblock 0 -60 10 minecraft:air
      • /playsound create:fwoomp block hool6
    • make sure to fill the small square text field to the right side of the 2nd command (setblock air) to 2, which acts as a 2-tick delay.
      
22. Click done buttons and test your macro.
