Notice about Longevity

Prism started in late 2013. I'm absolutely blown away that it remains an important plugin for so many server owners over a decade later. I try my best to keep it updated and have always appreciated the help of the community. PRs are always welcome.

The game, the plugin community, java itself, and my experience as a developer have all evolved and Prism v3 - while stable and trusted - shows its cracks.

Years ago I started v4 - a complete rewrite. It ran into some scheduling problems and licensing issue due to a library I used but it's still my wish to deliver this product someday. PRs are welcome there too.

Until then I will do my best to maintain v3, and even fix it up a bit, time-permitting.

Features Overview

• Prism tracks tons of different player, entity, and world events.
• Multiple tools and commands let you see exactly what happened.
• Powerful rollback/restore engine with complex search criteria.
• Several extra grief management features.
• Fully configurable wand system, with multiple modes and per-player personalization so it works exactly how you want.
• Rollback or restore events directly, or with a preview mode first.
• Highly configurable event tracking, to work just the way you want it.
• Safe command defaults (can be configured), very clean and easy to read chat messages.
• Requires MySQL/MariaDB

Event Detail

• Includes block changes, container access, item inserts/remove/pickups/drops, entity deaths, shearing, vehicle events, and a LOT more.
• Related events tracked to causing player like blocks falling, blocks detaching, trees growing, and much more.
• Smart logging and rollback of important related data like sign text, sheep color, wolf owner, animal age, villager profession, etc
• Tracks liquid flow and items that break because of it (lava/water-break can be tracked even when *-flow is off)
• Tracks world edits (requires WorldEdit)
• Fine-tuned config allows you to control tracking of every single event.
• Powerful config/personalization system for all wands - set the mode, item, even allow users to personalize how their own wands work.
• Inspector wand allows you to find history for single blocks/spaces.
• The /near command finds recent events around you.
• Lookup command is extremely powerful with our versatile parameters.
• Lookup results group together, turning hundreds of duplicate records for a player into one, with a count.
• Powerful parameters support exclusions, listing multiple, partial name filter, and more.
• Action names also have short-names for easier typing and can be used to combine related actions.
• Radius parameter supports world edit selections, basing off another online player, and more.
• A wide range of flags allow you to change lookup behavior at command time
• Very clean chat messages and paginated results to ease your burden, with clickable interface.

Rollbacks, Restore, Preview (R/R/P)

• Rollback and restore commands with powerful search criteria.
• Rollback or restore directly, or preview changes for both modes first.
• Apply/cancel previews, or let them auto-cancel after a minute.
• Extremely safe default parameters make it harder for you to make mistakes, but can be overridden in-game when you absolutely need them, or can be disable entirely via config.
• You can even rollback killed entities, items taken from containers, broken vehicles, and more.
• Sign rollbacks will restore their text
• Rollbacks of burn events also extinguish fires.
• Rollbacks of TNT/creeper explosion events also remove the laggy item drops.
• Heavily tested to ensure that rollbacks are smart - problem items like doors, beds, cactus, sugar cane, and others are always restored properly! No half-doors!
• Rollbacks/restores can be alerted to nearby players, and to staff members (staff see actual rollback params).
• Rollback systems moves any players or animals in the way to a safe position on rollback
• Rollback/restore world edits (requires WorldEdit 7.0.1)
• Advanced, optional flags give you ultimate control over the rollback/restore action at command-time.
