Dungeon Config

Every dungeon has its own unique config file that lets you further customize the dungeon's behaviour when played. This includes entry requirements, blocking certain potential out-of-bounds abuse (enderpearls, chorus fruit, etc), and reward cooldowns.

You can also modify the default-config.yml in the maps folder to change the default settings of a brand new dungeon.

An in-game editor for this config is planned for the future, but for now, you'll have to manually edit the config file.

NOTE: Gamerules are stored on the map itself and can be changed in-game with the standard /gamerule command while in edit mode.

How the config file is created and updated

A dungeon's config.yml is copied once from plugins/MythicDungeons/maps/default-config.yml, the first time the dungeon is loaded without one. It is never re-synced afterwards, so updating the plugin does not add new keys to existing dungeons. default-config.yml itself is only written when it is missing, so a plugin update does not refresh it either. Delete it and restart if you want the current one back on disk.

When a key is missing from a dungeon's config.yml, the plugin uses a built-in default instead. Four of those built-in defaults differ from what default-config.yml ships, so an old dungeon can behave differently from a freshly created one:

To pick up new options on an existing dungeon, copy the missing keys out of the current default-config.yml by hand.

Gamerules are not part of this file. They are stored in gamerules.yml next to it, written from the edit world when the dungeon is saved and re-applied every time an instance loads. Its keys are listed under The gamerules.yml file further down this page.

The default config file

Here is the default-config.yml provided by the plugin for your reference. It MAY contain features exclusive to dev builds, so check back here for new dungeon options!

One block has been moved in the listing below. The queue and ready-check overrides belong at the root of the file, not inside General:, so they are shown at the bottom here. See the warning under the block.

# dungeons where each player should enter independently.
#IgnoreParties: false

Careful: in the default-config.yml shipped today, that last block sits in the middle of the General: section. If you uncomment a line where it stands, the file stops being valid YAML and the dungeon will not load (Dungeon config has invalid YAML! in the console). Move the key you want to the bottom of the file, at column 0, instead.

Three comments in that file do not match what the code does:

• Version is not read by anything. It does not drive any migration, and changing it does nothing.
• KeepHealthOnEnter and KeepFoodOnEnter say the player is "set back to their previous health/food upon exit". That only happens when KeepInventoryOnEnter is false. With the shipped KeepInventoryOnEnter: true, health and food are never restored.
• BannedItems is not limited to vanilla materials. MythicMobs item IDs work in the same list.

Dungeon types

General.DungeonType decides which dungeon class runs the dungeon. It is matched case-insensitively, and each type has extra aliases. See Dungeon Types for what each one does.

An unrecognised type stops the dungeon from loading without an error message in the console: the dungeon simply never appears in /md status. Check your spelling first if a dungeon goes missing after an edit. (Typing a bad type into /md create or /md import does print No dungeon type by name ... found!, but a hand-edited config does not.)

Keys that do nothing in certain dungeons

One-world mode is not a dungeon type. It is the server-wide Experimental.OneWorldDungeons switch in the plugin config.yml. See One World Dungeons.

Procedural dungeons keep their generation settings in a separate generation.yml file, not here. See Default generation.yml.

General

General.LootCooldown

Stops players from looting the same rewards again too soon. Individual reward functions can override these values.

General.AccessCooldown

Limits how soon a player can play this dungeon again.

Players with dungeons.bypasscooldown (or dungeons.bypasscooldown.<dungeon>) skip the check entirely, which is the usual reason an access cooldown appears not to work when an admin tests it.

Queue, ready check and party options

These seven keys are read from the root of the dungeon config, not from inside General:. Putting them under General: means nothing reads them. Each one is optional: leave a key out and the dungeon uses the server-wide value from the plugin config.yml.

IgnoreParties: true makes the dungeon ignore the party system on entry: a partied player enters alone, with no group queue, no leader-only gating, no MinPartySize check against the party, and no party members pulled into the instance. It is mainly useful for CONTINUOUS dungeons where everyone should enter independently.

Requirements

Checked when a player tries to play the dungeon.

AccessKeys

The stack size stored on the key item is how many keys a player needs. Store a key item with an amount of 2, and a player carrying a single key does not have enough to enter on their own.

Difficulty

Difficulty levels scale mobs spawned by Mob Spawner functions and can override a handful of General settings. Pair them with the "Dungeon Difficulty" condition.

MobOverrides keys must match the spawner function's Mob field exactly, and all scaling only happens while EnableDifficultyLevels is true and the instance actually has a difficulty.

Set MobHealth, MobAmounts and MobDamage on every level you define. A scale left out of a level is read as 0, not 1, so a level that only sets MobHealth gets a mob count multiplier of zero and its spawner functions produce nothing.

Map

Configures a map item that draws the dungeon around the player.

The map is tagged as a dungeon item, so it follows General.DungeonItemInheritance and is stripped from players when they leave.

Rules

A few details that are easy to get wrong:

• SpawnAnimals and SpawnMonsters only matter while SpawnMobs is true. With SpawnMobs: false, nothing spawns naturally in the dungeon whatever the other two say.
• AllowedCommands and DisallowedCommands ignore a leading slash on both sides and are matched case-insensitively. An entry matches the typed command exactly, or as the start of it followed by a space, so md leave matches /md leave but not /mdleave. Players with dungeons.admin skip the whole check.
• An invalid material or entity name in the block lists and entity lists is logged in the console and skipped. It does not stop the dungeon from loading.

Options that are not in default-config.yml

These are read from a dungeon's config.yml but are not shipped in the default file. Add them by hand if you need them.

General:
  # When a player leaves, hand their dungeon items to a player still inside instead of removing them.
  # Access keys are always inherited, regardless of this setting.
  DungeonItemInheritance: true

# Casts a Mythic skill at the dungeon's start location on a repeating timer while the dungeon runs.
# (If the dungeon has no start location, the world spawn is used.)
# The value is the interval in seconds and must be 1 or higher; anything else is skipped with an error.
Skills:
  Tick:
    MyAmbienceSkill: 30
    MyHazardSkill: 5

# CONTINUOUS dungeons only.
ContinuousDungeons:
  # Keeps an empty instance loaded and waiting, so players never wait on a world load.
  LoadAtStart: false

General.Dimension, General.Regions, General.Lobby.Location and General.StartLocation also live in this file, but they are written by /md create, /md import, /md setlobby, /md setspawn and /md addregion. Set them with those commands rather than by hand: General.Dimension in particular is read case-sensitively, and a bad value stops the dungeon from loading.

The gamerules.yml file

gamerules.yml sits next to config.yml in plugins/MythicDungeons/maps/<dungeon>/. The plugin writes it from the edit world every time an edit session is saved, and applies it to every instance world as that world loads. The normal way to change any of it is to open the dungeon in edit mode, use the vanilla /gamerule and /difficulty commands, and save.

WorldTime and WorldWeather are written for every dungeon but only read in one-world mode, where the shared world cannot hold a per-dungeon time or sky. There, a dungeon whose values differ from the Experimental.OneWorldDungeonsWorld baseline in the plugin config.yml gets them shown to its own players as a per-player override. In every other mode the instance world carries its own time and weather, and these two keys do nothing. See One World Dungeons.

Gamerule paths are version dependent

The path under Gamerule. is whatever name the running server uses for that rule:

• Before 1.21.11, the flat legacy name, for example Gamerule.doFireTick or Gamerule.keepInventory.
• On 1.21.11+ and 26.x, the namespaced registry key with the colon written as a dot, for example Gamerule.minecraft.keep_inventory.

Hand-editing the legacy path on a modern server writes a key nothing reads. Read the file first and match the paths already in it.

The migration

Nothing migrates on a server before 1.21.11: the legacy paths are still the right ones there, and Version is left alone. On 1.21.11+ the file is brought up to Version: 3 on load, in one of two ways depending on what it says now.

Version missing or 1. The console logs Gamerule config for dungeon '<name>' is out of date! Updating..., and every entry is moved off the legacy paths:

• doFireTick and allowFireTicksAwayFromPlayer are resolved together into the single integer fire_spread_radius_around_player (0 for fire off, -1 for spread with no player nearby, 128 otherwise).
• disableRaids, disableElytraMovementCheck and disablePlayerMovementCheck are renamed to their positive form and their values inverted.
• Every other rule is moved to its new path unchanged. A name the server does not recognise logs Unknown gamerule: <name> and is dropped; spawnChunkRadius is dropped silently because the rule no longer exists.
• A Gamerule section that is present but empty is treated as damaged: the console logs Gamerules file corrupted!! Open this dungeon in edit mode and save to fix it!. Doing exactly that rewrites the file from the world.

Version: 2. Written by an earlier build that moved those three disable* booleans across without inverting them. Only that is corrected, in place (Correcting inverted gamerules for dungeon '<name>'...).

Invalid YAML anywhere in the file stops the dungeon loading, with Gamerule config has invalid YAML! in the console.

A rule that is simply missing from the file (a dungeon saved before that rule existed, or no file at all) falls back to the server's vanilla default, and the console notes each one it fell back on.

Values that accept placeholders

These options accept a plain number, a MythicMobs placeholder, or a math expression mixing the two (for example 2 + <dungeon.party.size>, or 30 + <dungeon.party.size> * 5). Placeholders need MythicMobs installed, and math expressions need MythicMobs Premium. Without them, the option falls back to its default.

General.TimeLimit, General.PlayerLives, General.MaxPlayers, General.CleanupDelay, General.KickOfflinePlayersDelay, ReadyCheckTime, Requirements.MinPartySize, Requirements.MaxPartySize, Requirements.MaxPartyDistance, Requirements.PlayerLevel, Requirements.Cost, and every Difficulty scale (MobHealth, MobAmounts, MobDamage, BonusMythicLevels, BonusLoot and all MobOverrides values).

Note that the %md_dungeon_<dungeon>_lives% placeholder reads General.PlayerLives as a plain number, so a dungeon that sets it to a placeholder or an expression reads as 0 there and displays Infinite. See Placeholder API.

Permissions that bypass these options

See Commands and Permissions for the full list.
