UHC
I made this a while back, its a UHC Battle royal type of game made out of command blocks. The file is a mcaddon but to make it work you will need to use a structure block or use the /structure load
/structure load UHC v2.2
Also here is a tutorial on how to use structure blocks (not made by me) : https://learn.microsoft.com/en-us/minecraft/creator/documents/structures/structureblockscommandtutorial?view=minecraft-bedrock-stable
I got help from some other ppl to make some of the commands but its been a while and Id love to credit them but I just don't remmeber who helped me.
If I remmeber correcly you need to have the admin tag to be able to access the command room [/tag @s add admin] You need to talk to a npc to go to the command room. There should be a book explainning how it works (in the ''admin room'').
Also there should be kits and a spectator mode that isnt with spectator for some reason (idk what I was doing).
You will have to turn on edu features, cuz of /ability
Also when you load the structure you will need to find your way in, usually I enter in the lobby by roof the command room, just break the barrier block and replace it after then talk to the npc
