+# J Grasscutter Command
+# 在QQ群里远程执行命令的插件
+
+- 基于 [Mirai-Console](https://github.com/mamoe/mirai-console) 开发的插件
+- 服务端必须使用 [OpenCommand](https://github.com/jie65535/gc-opencommand-plugin) 插件
+
+Mirai机器人相关文档请参阅 [用户手册](https://github.com/mamoe/mirai/blob/dev/docs/UserManual.md)，
+本项目**不会教你**如何安装和登录机器人，请自行了解Mirai相关信息。
+
+# 插件用法
+
+## 首先使用指令添加一个服务器
+```shell
+# 用法
+/jgc addServer <address> [name] [description]   # 添加服务器
+# 示例
+/jgc addServer http://127.0.0.1:443 测试服 本地测试服务器
+# 成功返回 "服务器已添加，ID为[1]，使用servers子命令查看服务器列表"
+# 失败返回 "只能设置装有 [OpenCommand](https://github.com/jie65535/gc-opencommand-plugin) 插件的服务器"
+# 失败的原因可能包含无法链接服务器、服务器没有安装插件等，具体可以参考日志
+
+# 如果你是服主，你可以添加OpenCommand的ConsoleToken
+/jgc setServerConsoleToken <id> <consoleToken>
+# 添加完成后，你可以将自己设置为管理员
+/jgc op <user>
+# 例如设置123456为管理员
+/jgc op 123456
+# 取消管理的子命令是 deop
+
+# 管理员执行命令将默认使用控制台Token，无需验证（见后文）
+```
+
+## 将服务器绑定到机器人所在群聊
+```shell
+# 用法
+/jgc linkGroup/bindGroup/addGroup <serverId> [group]   # 绑定服务器到群，在群内执行可忽略群参数
+# 示例（控制台）
+/jgc linkGroup 1 群号
+# 示例（群里）
+/jgc linkGroup 1
+# 成功返回 "OK"
+```
+在聊天环境执行 Mirai-Console 命令需要另一个插件 [Chat Command](https://github.com/project-mirai/chat-command)
+执行GC命令不需要这个，见后文
+
+## 绑定账号
+玩家想要在群里执行命令，需要绑定自己的游戏UID，需要在群里发送 `绑定 <uid>` 来向目标账号发送验证码，然后将验证码发到群里完成验证，如图所示
+
+![群内验证示例图](screenshot/verification.png)
+
+_管理员无需绑定，默认使用控制台令牌执行命令_
+
+绑定命令的触发关键字可以通过 `/jgc setBindCommand <prefix>` 来修改
+
+## 执行命令
+默认执行GC命令前缀为 `!` ，用法是 `!<命令|别名>`
+
+_可以通过 `/jgc setBindCommand <prefix>` 来修改执行命令前缀 _（例如以下示例图中使用`run`作为前缀）__
+
+---
+
+执行命令示例：`!prop unlockmap 1`
+
+![运行命令示例图](screenshot/runCommand.png)
+
+---
+
+执行别名示例：`!解锁地图`
+
+![运行别名示例图](screenshot/runAlias.png)
+
+命令别名可以通过 `/jgc setCommand <alias> <command>` 来设置，通过 `/jgc removeCommand <alias>` 来删除
+
+---
+
+命令还可以通过 @群员 来替代原先命令中的 @UID，前提是这个群员绑定了它的UID
+
+例如：`!permission list @张三`，其中`@张三`会被替换成其绑定的UID
+
+![At群员示例图](screenshot/runAt.png)
+
+## 拉黑用户
+如果你想禁止某个用户使用本插件执行命令，可以使用 `/ban <qq>` 来拉黑，使用 `/unban <qq>` 可以解除黑名单
+_（只是一个凭想象增加的功能，也许能用上呢）_
+
+## 群消息同步
+
+当你设置了服务器的 consoleToken，那么你可以使用 `/jgc setServerSyncMessage <id> <sync>` 命令来开启群消息同步功能。
+
+示例：`/jgc setServerSyncMessage 1 true` 表示启用1号服务器的消息同步功能
+
+当群里收到消息时，会执行命令 `/say 用户名 消息内容` 来将消息发送到服务器，因此玩家收到的消息也是来自服务器发送的。
+
+注意，为了避免徒劳的尝试，当任何一次消息发送失败时，都会自动关闭同步消息功能，需要手动重新启用。
+你可以自己更改相关规则，只需要修改源代码。
+
+![同步消息示例图](screenshot/syncMessage.png)
+
+**注意，玩家在游戏内发送的消息是不会同步到群的，这只是单向同步！！**
+
+# 配置文件(config.yml)
+```yml
+# 管理员列表，仅管理员可以执行控制台命令
+administrators: 
+  - 123456
+# 用户黑名单
+blacklist: []
+# 绑定命令：绑定 <UID> 示例：绑定 10001
+bindCommand: 绑定
+# 聊天中执行GC命令前缀：!<命令|别名>
+# 示例1：!give 1096 lv90
+# 示例2：!位置
+commandPrefix: !
+# 命令别名
+commandAlias: 
+  无敌: '/prop god on'
+  关闭无敌: '/prop god off'
+  无限体力: '/prop ns on'
+  关闭无限体力: '/prop ns off'
+  无限能量: '/prop ue on'
+  关闭无限能量: '/prop ue off'
+  点亮地图: '/prop unlockmap 1'
+  解锁地图: '/prop unlockmap 1'
+  位置: '/pos'
+  坐标: '/pos'
+```
+
+# 指令列表
+## 管理相关
+```shell
+/jgc help       # 插件命令用法
+/jgc reload     # 重载插件配置
+/jgc setCommandPrefix <prefix>      # 设置执行GC命令前缀
+/jgc setBindCommand <prefix>        # 设置绑定命令前缀

+/jgc setAdmin <user>    # 设置管理员
+/jgc deop <user>        # 解除管理员
+/jgc removeAdmin <user> # 解除管理员
+/jgc ban <user>         # 禁止指定QQ使用插件
+/jgc unban <user>       # 解除禁止指定QQ使用插件
+```
+
+## 服务器相关
+```shell
+/jgc ping <address|id>     # 测试指定服务器是否安装插件
+/jgc addServer <address> [name] [description]   # 添加服务器
+/jgc servers            # 列出服务器
+/jgc setServerIsEnabled <id> <isEnabled>        # 设置服务器是否启用
+/jgc setServerAddress <id> <address>            # 修改服务器地址
+/jgc setServerInfo <id> <name> <description>    # 设置服务器信息
+/jgc setServerConsoleToken <id> <consoleToken>  # 设置服务器控制台令牌
+/jgc setServerSyncMessage <id> <sync>           # 设置是否同步群消息到服务器
+```
+
+## 群相关
+```shell
+/jgc linkGroup/bindGroup/addGroup <serverId> [group]   # 绑定服务器到群，在群内执行可忽略群参数
+/jgc enable [group]     # 启用指定群执行，在群内执行可忽略群参数
+/jgc disable [group]    # 禁用指定群执行，在群内执行可忽略群参数
+```
+
+## 命令别名相关
+```shell
+/jgc setCommand <alias> <command>   # 添加命令别名
+/jgc removeCommand <alias>          # 删除命令别名
+```
