InvOwner
Overview
InvOwner is a powerful stealth and management GUI plugin designed for server administrators to monitor and manage players without being detected.
By utilizing packet-level interception, it completely conceals the administrator's presence not only from the in-game view but also from the Tab list, Tab completion, server list online count, and join/quit messages.
Additionally, it provides a dedicated inventory GUI that allows for intuitive moderation tasks such as Kicking and Banning players.
Key Features
- Complete Stealth (Packet-Level Hiding)
- Players in InvOwner mode are completely invisible to regular players.
- Excluded from the server list online player count (Ping).
- Login and Logout messages are hidden.
- Removed from the Tab list and command Tab completion.
- Forced Spectator Mode
- InvOwner mode automatically forces the player into Spectator mode to prevent accidental interference with the world.
- Intuitive Admin GUI
- Open a GUI listing all online players via a dedicated command.
- Simply right-click a target player to open an "Action GUI" for operations like Kick, Ban, or sending messages.
- Check the Banned player list and unban players directly from the GUI.
- Features an Anvil GUI for text input interfaces.
