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.
