BandwidthSaver-PE

Overview | 概述

BandwidthSaver-PE is a high-performance bandwidth throttling plugin built on the PacketEvents framework. Developed by the Mangocraft Code Team, it is a modernized fork of the legacy RIABandwidthSaver by Ghost-chu.

BandwidthSaver-PE 是一个基于 PacketEvents 的高性能节流插件。由 芒果方块的服务器开发制作组 基于 Ghost-chu 的旧版插件RIABandwidthSaver进行修改优化，旨在玩家处于 AFK 状态期间抑制不必要的数据包和区块发送，缓解服务器带宽压力。当进入ECO模式时会通过BOSSBAR提醒减少数据包展示Limit packet display. （All text within images can be modified in config.yml.

Improvements | 改进点

Modern Framework: Switched from ProtocolLib to PacketEvents for superior stability. (前置从 ProtocolLib 改为 PacketEvents，更稳定兼容)
Refined Logic: Optimized filtering algorithms for higher precision. (优化过滤算法，更准确高效)
Folia Support: Native compatibility with Folia. (增加对 Folia 服务器的支持)
AFK Fishing Fix: Added detection and handling for AFK fishing machines. (增加对自动钓鱼机的检测和处理)
Manual AFK Mode: Added /afk command for manual AFK mode that persists regardless of player movement. (新增/afk命令，提供手动AFK模式，不受玩家移动影响)

[!IMPORTANT]

Dependency: You must install PacketEvents for this plugin to function. (必须安装 PacketEvents 插件)

Note on Stats: Traffic statistics represent uncompressed data. Actual billed bandwidth may differ due to server-side compression. (统计信息为未压缩流量，实际流量因服务器压缩配置会有所出入)

Features | 功能

1. Dynamic View Distance | 动态视距

Lowers client-side view distance for AFK players without affecting server-side simulation distance.
降低 AFK 玩家的客户端视野距离，不影响服务器模拟距离，减少区块数据传输。

2. AFK Detection | AFK 检测机制

Perspective-Based: Monitors camera rotation (Default: 300s). 基于视角移动检测（默认 300 秒）。
Auto-Exit: Automatically restores traffic flow upon taking damage or using teleport commands (/tp, /spawn, /home, etc.). 受到攻击或使用传送命令时自动退出 AFK 模式。
Automation Friendly: Compatible with AFK pools and auto-clickers. 支持自动攻击和 AFK 池。
Manual AFK Mode: Players can use /afk command to enter manual AFK mode that persists regardless of player movement. Use /afk again or rejoin the game to exit. 手动AFK模式：玩家可使用/afk命令进入手动AFK模式，不受玩家移动影响。再次使用/afk或重新加入游戏可退出。

3. Packet Filtering | 数据包过滤详情

Cancelled (100% Suppression) | 取消发送:
- Animations, Block break, Sounds, Particles, Explosions, Time sync, Light updates, TAB list headers/footers, World events, Potion effects, Map data, etc.
- 动画、方块破坏、声音、粒子、爆炸、时间同步、光照更新、TAB 列表、世界事件、药水效果、地图数据等。
Throttled (Reduced Rate) | 频率削减:
- 2% Pass Rate: Entity movement, Position, Velocity, Experience orbs. (实体移动/位置/速度、经验球)
- 5% Pass Rate: Entity metadata. (实体元数据)
- 20% Pass Rate: Head orientation. (实体头部朝向)
Special Handling for AFK Fishing | 自动钓鱼机特殊处理:
- When a player holds a fishing rod, certain packets (sound effects, entity velocity/movement) are allowed to pass through to support fishing activities.
- 当玩家手持钓鱼竿时，某些数据包（声音效果、实体速度/移动）会被允许通过，以支持钓鱼活动。
