CPVisualizer

# CPVisualizer Private CoreProtect history visualization for **Paper 26.3 / Java 25**. Browse recorded block and container actions in an inventory GUI, then highlight matching positions only for the administrator running the search. Version 1.1.1 includes fully English menus and messages. ## Features - Independent search sessions and private BlockDisplay highlights for each administrator. - Search one historical player or all online and offline players. - Filter by a block material or search all block types together. - Placement, breaking, interaction, container additions and removals. - Time, world and radius filters, paginated results, event details and teleportation. - Bounded background queries with configurable limits. No client mod or ProtocolLib required. ## Installation 1. Stop the server. 2. Install a CoreProtect build compatible with Paper 26.3 and enable API 12. CoreProtect is a separate required dependency. 3. Put `CPVisualizer-1.1.1-paper26.3.jar` in `plugins/`. 4. Start Paper 26.3 with Java 25 and run `/cpv` as an operator. An [unofficial CoreProtect 24.1 compatibility port](https://github.com/vladnow/CoreProtect-Paper26.3) is available separately with source code and license. CPVisualizer does not bundle CoreProtect. Folia and other server platforms are not supported. ## All players and all blocks ```text /cpv player all /cpv block all /cpv action ALL /cpv time 24h /cpv radius 100 /cpv search ``` `/cpv blocks all`, `/cpv bloks all`, and `*` are also supported. CoreProtect system actors beginning with `#` are excluded from all-player results. Radius searches use an inclusive X/Z square across all heights. ## Permissions and limits Permissions default to operators: `cpvisualizer.use`, `cpvisualizer.search`, `cpvisualizer.teleport`. `cpvisualizer.admin` includes these and permits `/cpv reload`. Global all-player block searches cover loaded worlds. The default final limit is 500 events. Historical container types are inferred from retained logs; uncertain types are included only when all blocks are selected. Narrow the time or radius when a limit is reported. History and real blocks are never changed by visualization. ## Validation All 14 automated tests passed against both the official CoreProtect Maven API and the compatibility port. Integration checks passed on Paper 26.3 build 169 with SQLite, including filtering, multiple worlds, private non-persistent displays, and CoreProtect rollback/restore. Visual verification with two real game clients, MySQL, WorldEdit and Folia has not been completed. ## Links and license - [Full English documentation](https://github.com/vladnow/CPVisualizer/blob/main/README.md) - [Source and releases](https://github.com/vladnow/CPVisualizer) - [Issue tracker](https://github.com/vladnow/CPVisualizer/issues) - [CoreProtect upstream](https://github.com/PlayPro/CoreProtect) CPVisualizer is licensed under MIT.
