Data storage (quest progress)

Quest definitions come from datapacks (see Quest format). Quest progress — who has done what — is saved in your world. This page covers what NeroQuests stores, where it lives, and the controls over it.

Everything here is server-authoritative: progress only ever changes on the server, and the client is told what to draw.

What is stored

Kind Keyed by Contents
Player progress the player's Minecraft game UUID quest ID, one counter per objective, completion timestamp
Player activity stamp the player's Minecraft game UUID one "last updated" epoch-millisecond timestamp, used only for retention
Shared progress nothing (world-wide) for scope: server quests: quest ID, objective counters, completion timestamp

That is the complete list. NeroQuests stores no names, IP addresses, chat, coordinates or anything else about a player — nothing beyond the UUID Minecraft already uses.

Objective counters are indexed by the objective's position in the quest definition, so a datapack that appends an objective keeps existing progress meaningful. Reordering or removing objectives in a quest players have already started changes what the stored counters mean — append rather than reshuffle.

Progress for a quest that no longer exists (a datapack removed it) is simply kept and ignored; if the quest comes back, so does the progress.

Where it lives

In the world save, as one vanilla saved-data file (id neroquests:quest_progress) in the overworld's data/ folder, next to Minecraft's own saved data. It is written by the server whenever progress changes, saved with the world, and never leaves your machine. Deleting the world deletes it.

If the file is damaged

A corrupt or unreadable progress file does not crash the server. NeroQuests detects the bad read, starts from empty progress, and writes a clean file at the next world save. A warning is logged naming only the storage file and dimension — never a player or a stored value.

Retention

questDataRetentionDays in config/neroquests.properties controls how long an inactive player's progress is kept.

Value Behaviour
0 (default) NeroQuests runs no sweep of its own; progress is purged when Neroland Core's purge-inactive runs, per Core's dataRetentionDays.
1–3650 Any player whose progress has not changed in that many days is purged. The sweep runs once per server session, the first time quest progress is touched.

The sweep logs only the number of records purged. Shared scope: server progress belongs to the world, not to a player, and is never pruned.

Erasure

NeroQuests registers with Neroland Core's shared per-player erasure hook, so one request clears a player everywhere in the Neroland ecosystem at once:

  • players: /neroland data eraseme
  • admins: /neroland data erase <uuid>

That drops every quest row and the activity stamp for that UUID. Erasure never logs who was erased. Shared server-scoped progress is untouched — it holds no player identifiers.

Export (data access)

NeroQuests can produce a JSON export of one player's own progress and nobody else's: their quest IDs, objective counters and timestamps. No other player's rows and no shared progress are included, so an export can be handed to the player who asked for it as-is.

{
  "last_updated": 1750000000000,
  "quests": {
    "mypack:chapter1/wake_up": { "counters": [1], "completed_at": 1749990000000, "complete": true },
    "mypack:chapter1/first_steps": { "counters": [3, 0], "completed_at": 0, "complete": false }
  }
}

The in-game command that produces this file arrives with the quest-book and admin command set.
