一、计分板创建（聊天栏执行）

⚠️ 以下命令在聊天栏执行一次即可，无需放入命令方块。

1.1 个人统计（游戏自动维护）

# 玩家击杀数（只统计击杀玩家）
/scoreboard objectives add playerKills playerKillCount "玩家击杀"

# 死亡次数
/scoreboard objectives add deaths deathCount "死亡次数"

# 造成伤害（单位：半颗心，1 伤害 = 半颗心）
/scoreboard objectives add damageDealt minecraft.custom:minecraft.damage_dealt "造成伤害"

# 承受伤害
/scoreboard objectives add damageTaken minecraft.custom:minecraft.damage_taken "承受伤害"

1.2 团队统计与辅助目标（虚拟分数）

# === 团队累计（虚拟玩家 RedTeam / BlueTeam 持有）===
/scoreboard objectives add teamKills dummy "团队击杀"
/scoreboard objectives add teamDeaths dummy "团队死亡"
/scoreboard objectives add teamDamageDealt dummy "团队造成伤害"
/scoreboard objectives add teamDamageTaken dummy "团队承受伤害"

# === 个人 KD 比率 ===
/scoreboard objectives add kdRatio dummy "KD比率"

# === 增量同步值（每人每维度一个）===
/scoreboard objectives add lastKillSync dummy "击杀同步"
/scoreboard objectives add lastDeathSync dummy "死亡同步"
/scoreboard objectives add lastDmgDealtSync dummy "伤害同步"
/scoreboard objectives add lastDmgTakenSync dummy "承伤同步"

# === KD 精度常数 ===
/scoreboard objectives add const100 dummy
/scoreboard players set #100 const100 100

二、队伍创建与成员管理（聊天栏执行）

⚠️ 1.20.5+ 中 /scoreboard teams 已拆分为独立命令 /team。

2.1 创建队伍

/team add Red "红队"
/team add Blue "蓝队"

2.2 将玩家加入队伍

# 替换 玩家名 为实际 ID
/team join Red 玩家名
/team join Blue 玩家名

# 批量加入示例
/team join Red Alice
/team join Red Bob
/team join Blue Charlie
/team join Blue David

2.3 队伍管理命令

/team list              # 查看所有队伍
/team list Red          # 查看队伍成员
/team leave 玩家名      # 将玩家移出队伍
/team remove Red        # 删除队伍

---

三、计分板显示（聊天栏执行）

侧边栏同一时间只能显示一个目标，根据需要切换：

# 显示团队击杀（推荐默认）
/scoreboard objectives setdisplay sidebar teamKills

# 或显示个人 KD
/scoreboard objectives setdisplay sidebar kdRatio

# 或显示个人击杀
/scoreboard objectives setdisplay sidebar playerKills

# 隐藏侧边栏
/scoreboard objectives setdisplay sidebar

---

四、命令方块布置方案

核心原理

playerKillCount、deathCount、damage_dealt、damage_taken 是游戏统计自动维护的只读分数——玩家每杀一人/死一次/造成伤害/承受伤害，对应分数自动增加，无法被 /scoreboard players reset 真正清零（reset 后游戏下次同步会恢复原值）。

正确做法是用虚拟分数记录「上次同步值」，每次只把增量加到团队总分：

增量 = 当前值 - 上次同步值
团队总分 += 增量
上次同步值 = 当前值

初值未设置时视为 0，首次运行会把全部历史数据一次性计入团队。

方案 A：命令方块链

共 29 个命令方块（1 脉冲 + 28 链），覆盖 4 项统计 × 2 个队伍 + KD 计算。

[红石时钟] → [脉冲①] → [链②~⑬ 红队] → [链⑭~㉕ 蓝队] → [链㉖~㉙ KD]

✅ 所有链命令方块均设为无条件 + 始终活动，箭头指向同一方向。

第 1 组：红队增量同步（② ~ ⑬）

序号	命令	说明
①	(脉冲方块，触发整条链)	由时钟控制
②	execute as @a[team=Red] run scoreboard players operation RedTeam teamKills += @s playerKills	击杀 +当前
③	execute as @a[team=Red] run scoreboard players operation RedTeam teamKills -= @s lastKillSync	击杀 -上次 = 增量
④	execute as @a[team=Red] run scoreboard players operation @s lastKillSync = @s playerKills	击杀 更新同步
⑤	execute as @a[team=Red] run scoreboard players operation RedTeam teamDeaths += @s deaths	死亡 +当前
⑥	execute as @a[team=Red] run scoreboard players operation RedTeam teamDeaths -= @s lastDeathSync	死亡 增量
⑦	execute as @a[team=Red] run scoreboard players operation @s lastDeathSync = @s deaths	死亡 更新同步
⑧	execute as @a[team=Red] run scoreboard players operation RedTeam teamDamageDealt += @s damageDealt	造成伤害 +当前
⑨	execute as @a[team=Red] run scoreboard players operation RedTeam teamDamageDealt -= @s lastDmgDealtSync	造成伤害 增量
⑩	execute as @a[team=Red] run scoreboard players operation @s lastDmgDealtSync = @s damageDealt	造成伤害 更新同步
⑪	execute as @a[team=Red] run scoreboard players operation RedTeam teamDamageTaken += @s damageTaken	承伤 +当前
⑫	execute as @a[team=Red] run scoreboard players operation RedTeam teamDamageTaken -= @s lastDmgTakenSync	承伤 增量
⑬	execute as @a[team=Red] run scoreboard players operation @s lastDmgTakenSync = @s damageTaken	承伤 更新同步

第 2 组：蓝队增量同步（⑭ ~ ㉕）

与红队完全对称，仅 team=Red → team=Blue、RedTeam → BlueTeam。

序号	命令	说明
⑭	execute as @a[team=Blue] run scoreboard players operation BlueTeam teamKills += @s playerKills	击杀 +当前
⑮	execute as @a[team=Blue] run scoreboard players operation BlueTeam teamKills -= @s lastKillSync	击杀 增量
⑯	execute as @a[team=Blue] run scoreboard players operation @s lastKillSync = @s playerKills	击杀 更新同步
⑰	execute as @a[team=Blue] run scoreboard players operation BlueTeam teamDeaths += @s deaths	死亡 +当前
⑱	execute as @a[team=Blue] run scoreboard players operation BlueTeam teamDeaths -= @s lastDeathSync	死亡 增量
⑲	execute as @a[team=Blue] run scoreboard players operation @s lastDeathSync = @s deaths	死亡 更新同步
⑳	execute as @a[team=Blue] run scoreboard players operation BlueTeam teamDamageDealt += @s damageDealt	造成伤害 +当前
㉑	execute as @a[team=Blue] run scoreboard players operation BlueTeam teamDamageDealt -= @s lastDmgDealtSync	造成伤害 增量
㉒	execute as @a[team=Blue] run scoreboard players operation @s lastDmgDealtSync = @s damageDealt	造成伤害 更新同步
㉓	execute as @a[team=Blue] run scoreboard players operation BlueTeam teamDamageTaken += @s damageTaken	承伤 +当前
㉔	execute as @a[team=Blue] run scoreboard players operation BlueTeam teamDamageTaken -= @s lastDmgTakenSync	承伤 增量
㉕	execute as @a[team=Blue] run scoreboard players operation @s lastDmgTakenSync = @s damageTaken	承伤 更新同步

第 3 组：个人 KD 计算（㉖ ~ ㉙）

序号	命令	说明
㉖	execute as @a[scores={deaths=0}] run scoreboard players set @s deaths 1	防除零
㉗	execute as @a run scoreboard players operation @s kdRatio = @s playerKills	KD = 击杀
㉘	execute as @a run scoreboard players operation @s kdRatio *= #100 const100	KD × 100
㉙	execute as @a run scoreboard players operation @s kdRatio /= @s deaths	KD ÷ 死亡

📊 阅读 KD：显示 166 = KD 1.66，显示 40 = KD 0.40。将 #100 改为 1000 可获更高精度。

红石时钟说明

推荐以下方式触发脉冲命令方块：

• 漏斗时钟（5 秒以上间隔）
• 观察者时钟（配合红石）
• 循环命令方块 + /schedule（无需物理方块，需配合数据包函数使用）

---

方案 B：数据包函数（推荐）

如果你有数据包权限，把全部命令写进一个 .mcfunction 文件比摆 29 个方块简单得多。

目录结构

在存档的 datapacks/ 下创建：

datapacks/kd/
├── pack.mcmeta
└── data/
    └── kd/
        └── function/
            └── sync.mcfunction

pack.mcmeta

{
  "pack": {
    "pack_format": 41,
    "description": "KD Scoreboard Sync"
  }
}

pack_format：1.20.5/1.20.6 = 41。其他版本参考 Minecraft Wiki。

sync.mcfunction

直接把方案 A 的 28 条命令（② ~ ㉙）复制进去，去掉序号即可：

# === 红队 ===
execute as @a[team=Red] run scoreboard players operation RedTeam teamKills += @s playerKills
execute as @a[team=Red] run scoreboard players operation RedTeam teamKills -= @s lastKillSync
execute as @a[team=Red] run scoreboard players operation @s lastKillSync = @s playerKills
execute as @a[team=Red] run scoreboard players operation RedTeam teamDeaths += @s deaths
execute as @a[team=Red] run scoreboard players operation RedTeam teamDeaths -= @s lastDeathSync
execute as @a[team=Red] run scoreboard players operation @s lastDeathSync = @s deaths
execute as @a[team=Red] run scoreboard players operation RedTeam teamDamageDealt += @s damageDealt
execute as @a[team=Red] run scoreboard players operation RedTeam teamDamageDealt -= @s lastDmgDealtSync
execute as @a[team=Red] run scoreboard players operation @s lastDmgDealtSync = @s damageDealt
execute as @a[team=Red] run scoreboard players operation RedTeam teamDamageTaken += @s damageTaken
execute as @a[team=Red] run scoreboard players operation RedTeam teamDamageTaken -= @s lastDmgTakenSync
execute as @a[team=Red] run scoreboard players operation @s lastDmgTakenSync = @s damageTaken

# === 蓝队 ===
execute as @a[team=Blue] run scoreboard players operation BlueTeam teamKills += @s playerKills
execute as @a[team=Blue] run scoreboard players operation BlueTeam teamKills -= @s lastKillSync
execute as @a[team=Blue] run scoreboard players operation @s lastKillSync = @s playerKills
execute as @a[team=Blue] run scoreboard players operation BlueTeam teamDeaths += @s deaths
execute as @a[team=Blue] run scoreboard players operation BlueTeam teamDeaths -= @s lastDeathSync
execute as @a[team=Blue] run scoreboard players operation @s lastDeathSync = @s deaths
execute as @a[team=Blue] run scoreboard players operation BlueTeam teamDamageDealt += @s damageDealt
execute as @a[team=Blue] run scoreboard players operation BlueTeam teamDamageDealt -= @s lastDmgDealtSync
execute as @a[team=Blue] run scoreboard players operation @s lastDmgDealtSync = @s damageDealt
execute as @a[team=Blue] run scoreboard players operation BlueTeam teamDamageTaken += @s damageTaken
execute as @a[team=Blue] run scoreboard players operation BlueTeam teamDamageTaken -= @s lastDmgTakenSync
execute as @a[team=Blue] run scoreboard players operation @s lastDmgTakenSync = @s damageTaken

# === KD 计算 ===
execute as @a[scores={deaths=0}] run scoreboard players set @s deaths 1
execute as @a run scoreboard players operation @s kdRatio = @s playerKills
execute as @a run scoreboard players operation @s kdRatio *= #100 const100
execute as @a run scoreboard players operation @s kdRatio /= @s deaths

触发方式

# 方式一：手动触发一次
/function kd:sync

# 方式二：循环命令方块 + schedule 自调度（推荐）
# 在 sync.mcfunction 末尾加一行：
schedule function kd:sync 5s

# 然后手动执行一次 /function kd:sync 即可启动循环

不需要红石时钟，不需要摆命令方块。/reload 即可热更新函数内容。

方案对比

	方案 A：命令方块链	方案 B：数据包函数
搭建难度	摆 29 个方块 + 逐个贴命令	创建 3 个文件
修改维护	逐方块点开编辑	编辑 .mcfunction 后 /reload
依赖	红石时钟	/schedule（无物理方块）
适用场景	纯生存 / 无管理员权限	有数据包/管理员权限
性能	每 tick 检查方块	直接执行，更轻量

五、KD 比率说明

百分制 KD

Minecraft 计分板只存整数，5 杀 ÷ 3 死 = 1（不是 1.67），2 杀 ÷ 5 死 = 0。因此采用 先乘 100 再除 的百分制：

实际 KD	计分板显示
2.50	250
1.66	166
1.00	100
0.40	40
0.00	0

避免除以零

命令 ㉖ 在计算 KD 前把所有 deaths=0 的玩家临时设为 1。这只影响计分板显示，不会改动游戏底层的真实死亡数。

六、常用管理命令速查

6.1 查看玩家数据

# 查看某玩家的全部计分板分数
scoreboard players list 玩家名

# 查看某玩家特定目标的分数
scoreboard players get 玩家名 playerKills

6.2 查看团队数据

# 查看红队全部统计（虚拟玩家 RedTeam）
scoreboard players list RedTeam

# 查看蓝队全部统计
scoreboard players list BlueTeam

6.3 分数操作

操作	命令
手动加分	scoreboard players add 玩家名 目标名 数值
手动设分	scoreboard players set 玩家名 目标名 数值
重置分数	scoreboard players reset 玩家名 目标名
分数转移	scoreboard players operation A 目标A = B 目标B

6.4 计分板管理

操作	命令
查看所有计分板	scoreboard objectives list
删除计分板	scoreboard objectives remove 目标名
修改显示名称	scoreboard objectives modify 目标名 displayname "新名称"

---

七、注意事项

7.1 关于 reset 命令

准则类型	示例	reset 效果
游戏统计	playerKillCount、deathCount、damage_dealt、damage_taken	暂时清空，下次同步恢复 ❌
虚拟准则	dummy（teamKills、kdRatio、lastKillSync 等）	真正删除，可重新赋值 ✅

✅ 统计面板（ESC → 统计信息）中的原始数据无法被任何 /scoreboard 命令修改。

7.2 方案原理

playerKillCount 等游戏统计准则是引擎维护的只读数据，无法 reset 清零。因此必须用增量同步：每次只把「当前值 - 上次同步值」的差额加给团队，然后更新同步值。

7.3 命令方块设置

• 脉冲命令方块：需要红石信号触发，设为"需红石"
• 链命令方块：全部设为无条件 + 始终活动，防止某队无人在线时链条断裂
• 箭头方向必须一致，排在脉冲方块正后方
• 虚拟分数（RedTeam、BlueTeam、#100）无需手动初始化——未设置时默认 0

7.4 性能建议

• 红石时钟间隔建议 5 秒以上
• 使用 @a[team=Red] 等过滤条件减少运算量
• 服务器人数较多时，建议只在活动期间开启统计
