PrismProtect — protect your modded Minecraft server

Requires Architectury API

PrismProtect is a server-side(and client for hightlighting) Architectury mod for Minecraft 1.20.1–1.20.4 that brings CoreProtect-like logging and rollback to modded servers — no plugins required, built for performance.

Features

• Logs block break/place/replace with full BlockEntity NBT support
• Tracks explosions (TNT, creepers, vanilla explosion pipeline)
  Note: some mods with fully custom explosion logic may bypass vanilla hooks and not be logged
• Logs entity deaths with full NBT snapshots for accurate restoration
• Records container and inventory changes with menu open/close diff tracking
• Logs item drops from broken blocks and crafting outputs for item rollback
• Supports blocks/entities from any mod (namespaced IDs are stored as-is)
• Uses optimized SQLite storage with WAL journaling and thread-safe writes
• Includes inspect mode to view block history in-game

Commands

/pp inspect

Toggle inspect mode and click blocks to view history.

/pp lookup [u:<name>] [t:<time>] [r:<radius>] [a:block|entity|container]

Search logged actions using filters (a:block by default).

/pp rollback [u:<name>] [t:<time>] [r:<radius>] [a:entity]

Rollback changes in the selected scope.
Without a:entity, rolls back block/container/item changes.

/pp highlight [off] [u:<name>] [t:<time>] [r:<radius>] [w:<world>] [d:<sec>] [l:<limit>] [p:<page>]

Highlights matched block changes with in-world colored outlines for visual investigation.
Use off to clear active highlights immediately.
Running /pp highlight ... again replaces the previous highlight set for that player.

/pp restore [u:<name>] [t:<time>] [r:<radius>]

Restore previously rolled-back block/container/item changes.

/pp purge t:<time>

Delete old log data (requires OP level 4).

/pp status

Show database counters and runtime status.

Time Format

Supports s, m, h, d, w
Examples: 30m, 1h30m, 2d, 1w

Highlight Mode

Use /pp highlight to render outline markers for matched block changes in-world.
Colors indicate action type, and /pp highlight off clears active highlights immediately.

Entity Rollback

Entity rollback is a separate scope: add a:entity to rollback commands.
PrismProtect respawns entities at original coordinates using full NBT snapshots captured at death.

Item Rollback

PrismProtect logs:

• item drops from broken blocks
• crafting outputs taken from result slots

During /pp rollback, it restores affected blocks and tries to remove logged items from the original player inventory.
If items are missing there, it also checks nearby ground drops around the original position.

Storage

PrismProtect uses bundled SQLite (no external DB required).
Database path: config/prismprotect/prismprotect.db
WAL journaling provides safe concurrent access under active server load.
