# FakePlayer - 假人插件
这个插件模拟出真实的玩家来保证区块的加载以及怪物的刷新
### 支持版本
1.20.1 的 paper, purpur(建议)
## 命令
+ /fp create - 创建一个假人
+ /fp remove - 删除假人
+ /fp tp - 传送到假人身边
+ /fp tphere - 将假人传送到自己身边
+ /fp tps - 与假人交换位置
此外，假人是一个模拟玩家，因此可以被任何指令所识别比如 `kick`, `tp`, `ban` 等等
## 权限
+ fakeplayer.spawn - 创建、删除假人
+ fakeplayer.tp - 假人 tp 权限
+ fakeplayer.admin - 管理员权限
## 配置项
这个不定时更新内容，具体以插件的 `config.yml 为准`
```yml
# 服务器最多存在多少个假人
# 默认: 1000
server-limit: 1000
# 每个玩家最多创建多少个假人
# 默认: 1
player-limit: 1
# 每多少个 ticks 触发一次假人动作更新
# 这个值调的越大, 假人的动作更新越慢
# 单位 tick
tick-period: 1
# 假人创建者玩家下线时是否自动下线
follow-quiting: true
# 是否检测 IP
# 如果启用, 则一个 IP 只能创建 `player-limit` 个假人
# 能够避免玩家开小号疯狂创建假人
detect-ip: false
# 服务器最近 5 分钟平均 TPS 低于这个值清除所有假人
# 每 60 秒检测一次
# 默认: 0, 即不开启, 因为移除假人可能导致玩家炸机器, 按需开启吧
kale-tps: 0
# 假人不定时胡言乱语
# 每 6000 ticks(大约 5 分钟) 有 1/3 的几率胡言乱语
nonsense:
- 当个假人好累啊
- 能不能给个凳子坐坐？
- 靠，这里蚊子有点多
- 腐竹，救我！我动不了了
- 能不能让我玩会生存？
- 你好，我是学生，v我50可以吗
- 服务器将在 5 秒钟清除垃圾，请小心手上的物品 (
- 你们卡吗，我怎么动不了了
- 能不能在我这里建个挂机池？
- 汤姆哥有点小帅
```
