WorldEditDisplay

Summary

WorldEditDisplay 2.5.1 is a patch release that restores reliable WorldEditCUI client detection and handoff while making player display settings and renderer refresh commands apply consistently.

Players without WorldEditCUI continue to use the built-in server renderer. Players with the client mod are now detected from the official version handshake and receive native CUI packets without duplicate server-side selection displays.

WorldEditCUI Compatibility

• Detects the official direct worldedit:cui version handshake (v|4 and future protocol versions)
• Retains compatibility with legacy minecraft:register channel announcements
• Parses REGISTER payloads as exact NUL-separated channel names instead of substring matches
• Restores native WorldEditCUI priority even when server rendering is auto-enabled
• Keeps Bedrock/Floodgate clients on the server renderer

Renderer Handoff & Reliability

• Cancels pending server render work when a native CUI client is detected
• Clears selection display entities that were created before the client handshake arrived
• Prevents toggle, settings reload, and renderer refresh operations from recreating duplicate server displays for native CUI users
• Keeps CUI and Bedrock routing state visible across packet and scheduler threads

Player Settings & Command Fixes

• Makes whole-renderer resets clear cached player overrides correctly
• Makes /wedisplay reloadplayer discard pending in-memory edits before reloading saved settings
• Exposes and persists the missing max_grid_spacing and sqrt_scale_factor player settings
• Supports -1 as unlimited maximum grid spacing
• Refreshes active selections immediately after enabling rendering or reloading server configuration
• Rejects unknown /wedisplay view subcommands instead of unexpectedly toggling view-all mode
• Loads the bundled Simplified Chinese (zh_cn) language resources
• Corrects the grid-division command example to use a value within the default player limits

Testing & Build Updates

• Added unit coverage for direct CUI handshakes, legacy REGISTER lists, exact channel matching, native-client routing, and Bedrock fallback
• Extended the Paper/Mineflayer end-to-end test with normal and CUI-capable clients
• Verifies that silent server handshake injection does not falsely detect normal clients
• Verifies native client detection, existing entity cleanup, outbound CUI forwarding, and renderer refresh suppression
• All 47 unit tests pass, and the Paper 1.21.11 end-to-end workflow passes with PacketEvents 2.13.0

System Requirements

Upgrade Notes

• No breaking configuration changes from 2.5.0
• Existing player settings and accepted share relationships remain compatible
• Native WorldEditCUI users no longer need to disable the server renderer manually
• Update PacketEvents to 2.13.0 or newer before upgrading
• A full server restart is recommended after replacing the plugin JAR
• No client-side mod is required for the built-in renderer

Download

The Paper-compatible plugin JAR is attached to this release. The same artifact supports Paper and Folia; use the Spigot build profile when producing a dedicated Spigot artifact from source.
