求禁止飞行的插件，neverlag试过了无法生效，ncp的限速不会调，玩家走路都不顺畅。清道夫有一个限制玩家移动速度，用了之后还是可以飞，而且走路会卡住，op飞行也会卡住清道夫的限制配置

#This limits how fast a user can move from chunk-to-chunk and will prevent users from overloading your server
#I HIGHLY recommend you use this on servers with increased player-speeds/or fly enabled
# -- 'limit-only-fly' ONLY limit players who are currently flying
# -- 'chunk-to-chunk-time' is in milliseconds. It's the time users are allowed to move from one chunk
# -- to another.  Going faster over chunks then that number will cancel their movement
player-speed-limiter:
  enabled:false (试过了，会卡)
  chunk-to-chunk-time: 600（试过了，没啥用）
  limit-only-fly: false （试过了，会卡）



= =求一个能不让普通玩家飞行的插件。

目前只能NCP

求生存fly的限速配置和算法。
