UIM Minecraft – Hotbar Only

![UIM Minecraft restricts you to just 10 slots](https://cdn.modrinth.com/data/cached_images/c1b4bc9d3038e1b5f593417654961835aee3fdb6.png)
# About
UIM Minecraft is a datapack that restricts your inventory exclusively to the hotbar, while also preventing the storage of your items in chests, and other inventory-containing items.

This pack was inspired by Old School Runescape’s Ultimate Ironman mode.

# Mechanics
UIM Minecraft aims to restrict any game mechanic that would allow you to indefinitely store an *arbitrary* item in any way besides your own inventory.
– **Your inventory is restricted** to your hotbar, offhand, and equipment only. Every other slot is unusable, and attempting to place an item in it will drop the item.
– **Chests generated in the world will be locked.**
– **Furnaces are crafted pre-loaded with coal** or a coal block in the centre of the recipe. Once placed, the furnace starts immediately, and pops once it runs out of fuel. This is to allow the smelting of items while making storage in furnaces infeasible. You can also use bamboo, blaze rods, dried kelp blocks, leaf litter, or sticks.
– Minecart chests will be converted into locked barrels.
– Furnaces, smokers, and blast furnaces generated in the world will break upon opening.
– Entities able to hold arbitrary items like llamas and item frames will be killed upon entering interaction range. (Don’t worry, elytra in end ships won’t despawn.)
– Item frames, chest boats, hoppers, smokers, bundles, and ender chests aren’t craftable
– An exception is made for crafters, as you need to make one for an advancement.

# Notes
– This pack should work in multiplayer with small groups of people. Beyond that, no guarantees on performance or bugginess.
– This pack kills lots of entities and modifies blocks very easily. Don’t use it on an existing world if you value the lives of the llamas, item frames, chests, your inventory, etc. in the world!
– This pack doesn’t play nice with barrier blocks.
– Due to the way raytraces are handled in this datapack, sometimes furnaces don’t break when running out of fuel or chests don’t break upon opening. Avoid aiming at the edges of blocks and swinging your mouse quickly while interacting with these blocks.

UHC datapack

# Minecraft UHC (Ultra-Hard-Core) Datapack

![View on GitHub](https://github.com/lailai1653265/UHC_datapack)

This is a Minecraft UHC datapack that you can play in any world after downloading.

## Installation(Server&Client)

1. Download and unzip this datapack.
2. Place the datapack into the `datapacks` folder of your Minecraft world.
3. Enter Minecraft and reload your world with `/reload`.

## Usage

1. Enter `/function mypack:start_game` to load the game.
2. Enter `/function mypack:game` to start the game.

## How To Play
– At the start of the game, players will be transported to a high altitude and then gradually descend to the ground. Players need to quickly search for and collect resources before the boundary shrinks to ensure survival and prepare for subsequent battles. The ultimate goal is to defeat all other players.

## Features

– UHC Mode: Players cannot naturally regenerate health, relying instead on golden apples, potions, and other healing methods.
– Suitable for multiplayer gameplay.

## Notes

– Make sure you are using a compatible version of Minecraft with this datapack.

UHC World Generation

# UHC World Gen Datapack

This datapack tweaks Minecraft world generation for a better UHC game.

It’s also intended to be a template for anyone who wants to customize their world generation, because the datapack format is definitely tricky.

This pack was made for version 1.21.4, but should work on 1.21.x and future versions.
If breaking changes happen, please make an issue and I will try to update it!

## Features

– No oceans (large-ish rivers still generate)
– Increased frequency of small caves
– Less extreme mountains and hills
– World bottom moved to -32 instead of -64
– Rebalanced generation of ores (you can further customize this yourself too)

See `FEATURES.md` on my GitHub for a full list of features and how to customize them.

UHC Ready

# UHC Ready
With UHC Ready you can setup a UHC in a few minutes using a existing world

## Usage
1. Use `/reload` to reload all datapacks
2. Follow the chat prompts, if you can’t use the chat use `/function uhcr:start`
3. Wait for all the players to join then click [START] in the chat or use `/function uhcr:ready`

## Configuration
### Show Players’ HP on player list (TAB Menu)
To enable this feature you need to install the Show Player Health dependency datapack

### Time until the border shrinks
At the moment the only way to change the border shrink time is to manually edit some datapack files

By default the border will start to shrink after 10 minutes, but you can change this
1. Open the folder of the datapack and navigate to `/uhcready/data/uhcr/functions`
2. Open game_loop.mcfunction with your favorite text editor
![game_loop.mcfunction in a text editor](https://i.imgur.com/dmKPJME.png)
3. Go to the 4th line and change 12000 with the amount of time that you want to set in Minecraft ticks (20t = 1s)

UHC+

# UHC+: Adding More to UHC
Played enough standard UHC already? Looking for a unique twist on a classic mode? UHC+ augments the UHC experience by including a plethora of new features that will make each match different from the last.

In-depth Documentation showing information about Augments, Relics, Titans, and more: **Find it Here!**

## Overview Video

## What to expect
– A robust **Augment system** in which players select a perk at the start of the game. Each player chooses a different one, so each game will be a whole new adventure! There are 140+ augments and 3 different tiers of Augments, so there’s a lot of variety!
– **Gigantic Titans** that spawn throughout the game. Taking on these behemoths will net you great rewards!
– **Brand new structures** that will spice up exploration.
– **Special items and equipment** that can be obtained through Augments or traversing through arduous structures. These items can do wonderous things…
– **Rising Lava** at the final stage of the game that will keep the competition hot.
– A **grace period** system that stops players from attacking one another for a set time. Configurable in settings.
– **Built-in autosmelt** for ores and foods so that you can focus more on fighting than smelting.
– **An arrow count limit** to stop players from lugging too many Arrows around. Configurable in settings.
– Automatic system that stops players from entering the Nether and moves players in the Nether back to the Overworld. Configurable in settings.
– Staple UHC features like a shrinking world border, lack of natural regeneration, and permanent death.

## Installation
1. Download the Zip.
2. Place “uhc-plus.zip” into your respective datapack folder.
3. If you are playing on a server, go to your server.properties file and ensure that enable-flying is set to true and spawn-protection is set to -1.
4. Make sure the datapack is enabled. It’s better to add the datapack to a fresh, new world than a current world, so that the lobby and structures can generate properly. If the datapack was added while the server was running, make sure to run /reload.

## Special /trigger Commands

“`
/trigger settings
“`
Opens up a settings menu that allows for you to change the settings of the game if you have a high enough permission level. From here, you can change things like the augment tier, the number of Titans that spawn, the size of the worldborder, and more. Some settings can’t be changed when a game is started.

“`
/trigger top
“`
Can be used any time during the game to teleport you to the top of the surface, allowing for players to get to fighting each other more quickly. /trigger top has a 10 minute cooldown.

“`
/trigger augments
“`
Can be used any time during the game to show a list of the augments that other players have.

## Custom Crafting Recipes
Additional items can be crafted and used in-game.

### All-Seeing Eye
_All-Seeing Eye reveals where your enemies are by applying Glowing on them! More effective at close range._

![All-Seeing Eye Crafting Recipe](https://imgur.com/QCgBLsA.png)

### Player Tracking Compass
_Player Tracking Compass points towards the nearest enemy player. Quite useful for when you need to find a player from across the map!_

![Player Tracking Compass Crafting Recipe](https://imgur.com/3uaUQim.png)

### Gravel to Flint
_Gravel to Flint Crafting Recipe_
_Additionally, a recipe for Gravel to Flint is included. No need to deal with shoveling tons of Gravel during the game!_

![Gravel to Flint Crafting Recipe](https://i.imgur.com/FLuyMrh.png)

## Special Functions:
_These functions can be ran by an admin of the server to manually start/stop the game._
– uhcp:start manually begins the game, but we’d recommend starting by using the ready up system.
– uhcp:reset resets all aspects of the UHC game to its original state. However, be warned that some things are not removed upon reset (such as rising lava).

UHC

# 🍏 UHC

UHC (abbreviation for Ultra HardCore) is a popular Minecraft survival minigame that can be played alone or with a team.
This mod also includes UHCRun, a variant of UHC that tweaks the game in many ways to make it 2x faster.

UHC is one of the minigames made for the Nucleoid Project, an effort to build an open source ecosystem for server-side Minecraft minigames.
You may even be interested in playing some of them over on our testing Minecraft server at `nucleoid.xyz`!
You can also find us on our Discord if you have any troubles or queries, or would like to get involved.

## Installation

UHC can be installed on a client or a server. As this is a multiplayer minigame though, it is recommended to install it on a server.

⚠ UHC **needs** the following mods to be installed:
– Plasmid: GitHub / Modrinth
– Fabric API: GitHub / CurseForge / Modrinth

## Usage

To start a game of UHC, use `/game open` and browse the list of available game modes.

## Modifications

To configure UHC, or to contribute to the project, visit the official documentation.
