FRTrustSystem
It is a powerful Minecraft plugin that introduces a trust and friendship system to protect players' property. With simple commands, players can trust others to access their blocks and storage, send friend requests, and receive notifications about suspicious activities. FRTS integrates with CoreProtect for block ownership tracking and supports multilingual functionality (English, Russian, Ukrainian, French).
The French and Ukrainian localizations could contain mistakes. We’ll fix it soon.
CoreProtect required! Downloald it here.
Key Features
- Trust System: Players can add others to their trusted list, allowing them to interact with their blocks (e.g., chests, furnaces) and storage without triggering violation notifications.
- Friendship System: Ability to send and accept friend requests, automatically adding friends to the trusted list.
- Notifications and Protection: The plugin notifies owners and moderators if someone attempts to break a block or take items from storage without permission.
- CoreProtect Integration: Utilizes the CoreProtect API to determine block owners, ensuring accurate protection.
- Flexible Configuration: Customizable settings in config.yml, such as block break checks, inventory take checks, owner and moderator notifications, and notification distance.
- User-Friendly: Easy-to-use commands like /trust, /friend, /friends, /trusted, and administrative commands such as /frtrust reload for reloading the configuration.
