ESU

A bukkit/velocity plugin that helps manage servers and provide a better gaming environment. Currently in actively developing.

Modern design; Full support of hot loading/unloading or hot updates.
All modules can be enabled and configured independently. (Modules are disabled by default) Modify the configuration or use commands to en/disable modules.
Supports language settings and will provide information based on the client language. You can also set the location of messages (chat, action bar, title) and sounds.
Custom color scheme feature, which allows players to choose their favorite themes! (Still in development)

Module List

ESU-Bukkit

NetworkThrottleModule

• New technique: effectively reduce the upload bandwidth usage by compressing the block data that is invisible to players in the chunk data packet. No impact on non-cheating players. Being deep optimization, the processing time of each chunk is less than 1ms. The load is lower than GrimAC and ore obscure plugins.
  Runing an 100-player vanilla survival server in months, this function helped reduce the upload bandwidth by about 50% (compared with non-anti-xray case). For detailed instructions, please check the comments in the module configuration.
  *This function requires the Paper Mojmap server.
  *This function conflicts with any Orebfuscator plugin and cannot be installed together. It provides some kind of ore obfuscation effect (like Paper engine 1).
  *This feature can still be further enhanced in the future.
• Cooperate with the Velocity plugin to monitor real-time bandwidth information and dynamically adjust the chunk sending/reading rate for players according to bandwidth usage. Helps with bandwidth spikes and evenly distribute bandwidth usage.
• Dynamically adjust the view distance of high-latency players to reduce resource usage and improve player experience.

(PacketEvents required)

SpoofServerSettingsModule

• Modify view distance returned by the server. A high view distance can increase the vertical visual distance of the client in the chunk.
• Modify the simulation distance and world difficulty returned by the server.

(PacketEvents required)

ExploitFixModule

Fix vanilla exploits. Currently only fixs trident/bow duplication in 1.13+.

ChatAntiSpamModule

Literal meaning. Supports regular expressions.

AutoReloadExtensionPluginsModule

Automatically reload other plugins that depend on ESU and further improve the compatibility of hot reload/update ESU. Requires PlugMan/PlugManX.

AutoRestartModule

ESU-Velocity

NetworkThrottleModule

• Command /vnetwork trafficMonitor to view the real-time actual bandwidth usage and pps (estimated value) of the proxy.

  

• Packet analyzer, which can analyze the network usage more accurately. Provide filters.

• Cooperates with Bukkit plugin: dynamically adjust the chunk send/load rate for players according to bandwidth usage.

(PacketEvents required)

UserNameVerifyModule

Verify whether the username meets the requirements when the player enters the server. For offline proxy.

AutoReloadExtensionPluginsModule

Same as the one in Bukkit plugin, requires ServerUtils plugin.

(Work In Progress)

While this plugin already has some modules available, it is still in the design stage.
