UHC Function Addon

Ultra Hardcore is a custom game mode where the goal is for all players to defeat all the other players. This mode is mostly found on Java Edition servers, but now you can enjoy the game with your friends with this lightweight, easy-to-set-up addon!


Although there are many similar addons/server plugins for Bedrock Edition, most of these are quite complex to set up and is not customizable. Therefore, the goal of this addon is to become a vanilla Minecraft alternative that everyone can use. This add-on can be set up in seconds and does not require command blocks. There are also various settings allowing users to customize their game, including setting the game duration and changing world border size.

Get Started

This section will teach you how to start a game, step by step.

After you download and import the addon, go ahead a create a new world.

In the world options screen, navigate to “Behavior Packs” in the left-hand screen, and find UHC Function at your right-hand side. Click on “Activate” to apply the pack to your world.
After you apply it, you can then click on the cogwheel icon and choose the world border size for your game.

Then, navigate to Game at your left-hand side, and scroll down. Turn on Activate Cheats.

Then, click on Create and wait for the world to load.

Upon entering the world, open the chat menu, and type “/function UHC_setup”

You should now see the confirmation message. You can now change settings(refer to Customization) and ask all players to join. 

NOTE: You can let players join before you set up, but players will still be in survival mode.

After the players have joined, you may now start the game by opening your chat menu and executing “/function UHC_start”.

If you have done everything correctly so far, you should see the scoreboard showing the next event and all players should be spread around the arena. Good luck to all players!

This section will list all the available options in-game and how to change them.

To change a setting, open the chat menu and type “/function UHC_settings/SETTING/VALUE” where SETTING is the settings and VALUE is what you want to set it to. For example, to turn spectating off, type:

    i did /function UHC_setup then /function UHC_start and it wouldn’t start?

  2. Minerman99 says:

    So today I wanted to play a UHC with your pack with a group of friends with the latest update of this game. The problem with it was that it just didn’t start. I did the command “/function UHC_setup” and then “/function UHC_start,” and it just wouldn’t start. I would appreciate it if you could investigate the issue and tell me why this is happening. (Also, please add a “Deathmatch” mode and the other ores to your newest version.) Thank you.

  3. AceXMRealm says:

    I type /function UHC_settings/autosmelt/on but it says i am not the host how can fix this problem?

  4. WolfCheezy says:

    Sorry, I forgot to turn on experimental gameplay =( I’m very sorry ☹️.

  5. WolfCheezy says:

    It doesn’t work??? Why?

    • Hey, could you please provide details on:
      – What were you trying to do;
      – What were the expected results;
      – What were the actual results.
      There is a potential glitch where you are unable to start the game, simply execute the command a few more times.

  6. turkeymanyeet says:

    4-add heads , as a custom item and can be made into golden apple like normal apple can

    Thats it , add these and ur addon will be the pefect java like uhc mode

  12. Dystrom says:

  13. Owkiya says:

    Can I translate this thing into Chinese and make some adjustments to make Taiwanese people more used to it? I can give you the file.

    • Hi,
      Thank you for providing the opportunity for this to be translated, but coincidentally, I am also Chinese ?.
      I have thought about making a Chinese version of this addon, but the texts are in the function files instead of a separate .lang file. I am afraid that translating this will be too much work, but if you want to translate it into Chinese Traditional(I assume), no worries! Just please credit this original version.

  14. Guest-2260381578 says:

    Can u pls update this to 1.16

  21. Anonymous says:

    This is a very nice function pack but can you please make the timer last longer like small game should be this timer medium game should be 10 mins till pvp 25 min till Deathmatch and long should be like a normal uhc game 75 mins long

  22. Guest-5181808228 says:

    huh all the download links are broken

  23. Guest-7411576309 says:

    When i drop apples, they become enchanted golden apples. Why?

  24. At the end we kept respawning but thats fine we just looked in the chat to see who won i would like the deathmatch to not be in a ring maybe add a setting can you also add more setting such as auto smelt and leaves drop golden apples (ik this is all possible in command blocks so it might work in functions)

  25. Guest-6389725790 says:

    Can this be used as a single player mode? Cause I want a survival mode that has UHC hearts if not is there another add on that I can use?

  26. Guest-6591625097 says:

    Hi. what is shader being used in thumbnail and screenshots? please tell me Im really looking for a good looking W10 edition shader

  28. Guest-4656980160 says:

    How do i exit spectator mode

  29. Best function pack I’ve used!!! One major problem: in the deathmatch all player spawn in one spot, if you use the /spreadplayers (I think it’s called that) you can spread the players out inside the deathmatch arena. Right now the start of the deathmatch is very awkward. Another thing, you should add in supply crates and show the coordinates on each players screen, this would cause multiple players to go for it and start a PVP. Overall great function pack, DEFINITELY RECOMMEND!!!! 😀

  30. Zediax890 says:

    Dude your addon is AWESOME I was searching for this and you release it what a timing xD greate job this is super duper cool continue like that ?

  31. Guest-1198547207 says:

    Hi! i was wondering, this addon is great, but when entering deathmatch, can you make a cooler arena and make it so people spawn in different places, thanks!

  32. Guest-8967201756 says:

    Can you please add cut clean it’s like when you mine an iron ore you get iron and exp

  33. Guest-8944253664 says:

    /function UHC_start will not work for me… and you’re the only GOOD UHC addon I could find.
    I already did all the stuff before like using /function UHC_setup in the beggining before my friend joined but after testing it three times already, /function UHC_start, will just not work. I don’t know what the problem is and I play on Windows 10 Edition so hopefully you can find a way to resolve my issue, hope to get a response!

  34. KIRITO SAMA says:

    Can you give me the name of the shader pack placed with the description pictures?

  35. Guest-1880020804 says:

    I have a question. When’s I typed the function command, there was only function UHC start, UHC loop and UHC somethingloop. I couldn’t find UHC setup. What does it mean?

  36. FoxAW2468 says:
