Overview

HideAndSeek is a Minecraft minigame plugin in which one team hides while the other seeks. Hiders can disguise themselves as blocks, shrink to a tiny size, wear custom skins, or simply rely on good hiding spots, while seekers use a diverse arsenal of utility items to track, reveal, and eliminate them. The plugin is built on top of MinigameFramework (also developed by me), which handles phase management, team assignment, item registration, and player data persistence.

The plugin supports custom maps with per-map setting overrides, a lobby voting system for maps and game modes, a persistent loadout and cosmetic skin system, a round-based perk shop, detailed per-player statistics, and an extensive in-game settings GUI provided by MinigameFramework.

Game Modes

Mode	Description
`NORMAL`	Hiders hide in the map as themselves. Seekers hunt them down using their sword and utility items.
`BLOCK`	Hiders disguise as configurable blocks and blend into the scenery. Seekers must spot inconsistencies.
`SMALL`	Hiders are scaled down to a configurable size, making them much harder to spot. Seekers can optionally be resized too.
`SKIN`	Hiders disguise using custom skins (e.g. block-like or environment-matching skins) to blend into the landscape. They may also be optionally scaled down for increased difficulty.

Game modes can be changed via the in-game settings GUI or voted on by players in the lobby.

Features

Configurable hiding and seeking phase durations
World border support with per-map border configurations

Requirements

Requirement	Version
Java	21+
Paper (or Purpur)	1.21.10+
MinigameFramework	1.0.0

MinigameFramework

[!IMPORTANT] HideAndSeek depends on MinigameFramework, a companion library also developed by me. It is not currently publicly available, neither the JAR nor the source code.

[!NOTE] MinigameFramework will be released publicly in the future. This section will be updated when that happens.

Installation

Ensure your server runs Paper 1.21.10/11 with Java 21 or newer.
Wait until MinigameFramework.jar is released and place it in your plugins/ folder.
Place HideAndSeek-1.0-SNAPSHOT.jar in your plugins/ folder.
Start the server once to generate config files.
Set up at least two scoreboard teams via MinigameFramework's team configuration.
Add at least one map (see Map Setup).
Restart the server.

Quick Checklist

[ ] Java 21+ on the server
[ ] Paper 1.21.10/11 server jar
[ ] MinigameFramework.jar in plugins/
[ ] HideAndSeek-1.0-SNAPSHOT.jar in plugins/
[ ] Two teams configured in MinigameFramework
[ ] At least one map entry in plugins/HideAndSeek/maps.yml
[ ] Server restarted after first run

Configuration

The plugin generates config.yml and maps.yml in plugins/HideAndSeek/ on first run.

How settings work

All gameplay settings are managed through the in-game settings GUI, provided by MinigameFramework. The config.yml file only serves to override the default value of a setting. If a setting is not present in config.yml, the plugin's built-in default is used instead. Changes made in the GUI take effect immediately but do NOT persist across restarts.

A full list of available setting keys can be found in SettingRegistrar.java.

Map Setup

Maps are defined in plugins/HideAndSeek/maps.yml. Each key is the internal map name and must match the name of a world folder present on the server.

map1:
  pretty-name: "Starter Valley"
  description: "Default map"
  author: "Server Admin"
  size: "MEDIUM"
  icon: "GRASS_BLOCK"
  spawn-points:
    - "0,65,0,0,0"       # Format: x,y,z,yaw,pitch

    - "oak_log"
    - "stone"

World Border Format

If spawn-point count equals world-border count, each spawn is matched to its corresponding border by index. Otherwise, all spawns use the first border.

Block Pattern Syntax

The allowed-blocks list accepts a pattern DSL for flexible block selection:

Pattern	Meaning
`STONE`	Exactly the `STONE` material
`OAK_SLAB[type=bottom]`	Oak slab locked to a specific block state
`OAK_SLAB[*]`	Oak slab with any block state allowed
`*SLAB{OAK_SLAB}`	All slab variants, defaulting to Oak Slab
`*SLAB{OAK_SLAB}[type=bottom]`	All slab variants, default Oak Slab, locked block state
`#planks{OAK_PLANKS}`	All blocks in the `planks` Bukkit tag, default Oak Planks
`{STONE,GRANITE,DIORITE}`	Explicit custom material list

Skin Setup

Custom skins for SKIN mode are defined in plugins/HideAndSeek/skins.yml:

oak_log:
  name: "Oak Log"
  icon: "minecraft:oak_log"
  value: "<base64 skin texture value>"
  signature: "<base64 skin texture signature>"

Skin textures can be generated using services such as Mineskin. Each skin entry must have a valid signed value/signature pair.

Loadout System

Players configure their loadout in the lobby before each round. Each item has a rarity that determines its token cost.

Rarity	Default Token Cost
Common	1
Uncommon	2
Rare	4
Epic	6
Legendary	10

By default, hiders have 12 tokens and up to 3 item slots. Seekers have 12 tokens and up to 4 item slots. All values are configurable via the in-game settings GUI or under settings.loadout.* in config.yml.

Slot Preferences

Players can configure which item types (e.g. Mobility, Offense, Trap) are placed in which inventory slots, with a fallback type per slot. This is accessible from the loadout GUI via the Slot Preferences button.

Admin Preset System

Admins can define up to 5 role presets per role (hider/seeker) in the Admin Loadout Manager GUI (/mg loadout admin). Presets can be:

Enabled/disabled per slot
Forced: locks all players of that role to the specified preset
Restricted: players may only choose from enabled admin presets rather than building their own loadout

Perk System

At the start of each seeking phase, a random pool of perks is selected (configurable count). Players spend their accumulated round points in the perk shop to purchase perks.

Shop Modes

Inventory: perk items are placed directly in the player's second hotbar row during the seeking phase.
Vending Machine: dropper blocks are placed at positions defined in maps.yml under vending-machine-locations. Players interact with the dropper to open the shop.

Auto Aim	Guides the Seeker's Blade toward nearby hiders on throw (passive)

The NMS implementation currently targets Paper 1.21.10 (nms-v1_21_10) and Paper 1.21.11 (nms-v1_21_11). Adding support for another version requires a new Gradle module implementing the NmsAdapter interface and providing an NmsAdapterMeta that declares which Minecraft versions it supports.
