java集合块Bukkit性能友好
我目前正在编写一个游戏，其中包括大量的区块设置。 当一个玩家移动时，一个彩色玻璃通道将引导并跟随他的方向，并在5秒后消失
我已经检查过了，如果没有设置，那么只会设置块，如果玩家实际上正在将他的位置更改为另一个块，那么只会检查块
我也尝试过使用sendBlockChange来实现这一点，但首先，这无助于提高性能，因为sendBlockChange必须应用于所有在线玩家，其次，反作弊插件将变得疯狂，我没有时间编写新的NCP
因此，我在这里发布了moveEvent期间的实际块设置，并希望在此提供一些建议，以降低性能
目前，一台服务器需要大约5GB的内存来容纳3-5个播放器
谢谢各位

尝试在更新块之间实现一个小的等待时间。例如，玩家第一次触发块更新时，将条目存储在地图中，键入其UUID并使用当前时间值。然后，在下次激活事件时，检查当前时间与上次激活事件之间是否已过某个时间段。如果指定的时间没有过去，不要做任何事情。即使您将其更改为仍然每秒更新一次，也会比每滴答更新一次提高20倍
