检查距离中心一定距离内有多少人
Check how many people are within a certain distance from the center
我正在制作一个 Spleef 插件。
我需要统计大厅里的人数。
我以为我可以数出大厅中心一定距离内有多少人。
我认为这可能比在有人键入命令时记录更好。

我还没有从主 class 中调用 onPlayerJoin
方法。
我欢迎任何有更好的方法来计算大厅人数的人。
确保您有一个 Location
对象,您希望在该对象的中心找到附近的玩家。
Location center = new Location(world, x, y, z);
然后,根据需要的距离获得一个 double
值。
double distance = 10D;
首先,你应该对服务器上的所有玩家进行循环:
for (Player player : Bukkit.getOnlinePlayers()) {
}
然后,获取player
的位置:
for (Player player : Bukkit.getOnlinePlayers()) {
Location location = player.getLocation();
}
现在我们可以检查两个位置(center
和 location
)之间的距离:
for (Player player : Bukkit.getOnlinePlayers()) {
Location location = player.getLocation();
if (location.distanceSquared(center) <= distance * distance) {
// Do something
}
}
注意:你应该使用distanceSquared(Location)
,它相当于distance(Location)
的结果平方,因为distance(Location)
使用Java的平方根法,非常耗资源。
最终结果:
double distance = 10D;
Location center = new Location(Bukkit.getWorld("world"), x, y, z);
for (Player player : Bukkit.getOnlinePlayers()) {
Location location = player.getLocation();
if (location.distanceSquared(center) <= distance * distance) {
// Do something
}
}
loc.getWorld().getNearbyEntities(loc, distance, distance, distance).stream()
.filter(e -> e instanceof Player)
.findFirst()
.orElse(null);
就这样做
