CMA-ES PvP Sword

CMA-ES PvP Sword is a Fabric server-side mod for Minecraft Java Edition 1.21.11. Its core goal is to cultivate multiple independent PvP combat fake players in a server-side environment and continuously optimize their combat strategies through an evolutionary algorithm, enabling these fake players to:

• exist in the server world as independent combat entities that can be attacked by players and other fake players;

• autonomously find targets, approach targets, attack targets, and make advance/retreat decisions based on health, distance, and combat situation;

• display stable and diverse combat behaviors when facing different enemies, without relying on any manually written fixed scripts;

• be spawned, removed, toggled, switched between running modes, and have their status viewed through commands.

• The combat strategies of these fake players are not predefined; instead, they are autonomously learned during combat through a continuously running evolutionary loop.

The mod provides a set of commands to control fake players:

When spawning a fake player, the username is validated: length is limited to 3 to 16 characters, and only letters, numbers, and underscores are allowed.

指令	作用
spawn	Spawns a fake player at the command executor's location
spawnAt	Spawns a fake player at the specified player's location
remove	Removes and saves the specified fake player
toggle	Toggles the combat switch of the specified fake player
mode	Switches the optimization/usage mode of the specified fake player
status	Outputs the status line of the specified fake player

clearAll	Removes all fake players

CMA-ES PvP Sword 是一款面向 Minecraft Java 版 1.21.11 的 Fabric 服务端 Mod。它的核心目标是：在服务端环境下培育多个独立的 PvP 战斗假玩家，并通过进化算法持续优化它们的战斗策略，使这些假玩家能够：

• 作为独立的战斗实体存在于服务器世界中，可被玩家和其他假玩家攻击；

• 自主地寻找目标、接近目标、攻击目标，并根据血量、距离与战况做出进退决策；

• 在面对不同敌人时展现出稳定而多样的战斗行为，不依赖任何人工编写的固定脚本；

• 通过指令被生成、移除、开关、切换运行模式和查看状态。

这些假玩家的战斗策略不是预先定义的，而是在战斗过程中通过一个持续运行的进化循环自主学习得到的。

Mod 提供一套指令用于控制假玩家：

生成假玩家时对指令中的用户名进行校验：长度限制在 3 到 16 字符，仅允许字母、数字与下划线。

指令	作用
spawn	在指令执行者位置生成一个假玩家
spawnAt	在指定玩家位置生成一个假玩家
remove	移除并保存指定假玩家
toggle	切换指定假玩家的战斗开关
mode	切换指定假玩家的优化/使用模式
status	输出指定假玩家的状态行
list	列举所有假玩家
clearAll	移除全部假玩家
