气泡剔除

Question

我正在尝试编写一个带有两个参数的命令：第一个是要泡泡的玩家，第二个是泡泡的半径。它看起来像 /bubble <player> <radius>.

我基本上希望任何在该半径范围内行走的人都被射出很远，但我真的不知道该怎么做。我坚持的主要部分是知道是否有人在距受害者 5 个街区以内（使用元数据）以及如何对他们进行排序。

向人们插入气泡元数据，以便我们知道谁在气泡中。

FixedMetadataValue metadataValue = new FixedMetadataValue(plugin, true);
victim.setMetadata("isInBubble", metadataValue);

现在你需要处理 PlayerMoveEvent 并让玩家围绕移动者并检查这些 "isInBubble" 中是否有这样的（不需要检查值）：

mover.hasMetadata("isInBubble");

要删除它，您需要使用与创建它时相同的插件 class。

mover.removeMetadata("isInBubble", plugin);

我为你写了这段代码：

@EventHandler
public void onPlayerMove(PlayerMoveEvent e) {
     Player mover = e.getPlayer();
     Location from = e.getFrom();
     Location to = e.getTo();
     Collection<Entity> nearbyEntities = mover.getWorld().getNearbyEntities(from,  10, 10, 10);//Get entities in a 10 block square from loc "from"
     List<Player> nearbyPlayers = new ArrayList<Player>();
     for (Entity en : nearbyEntities) {
         if (en instanceof Player)
           nearbyPlayers.add((Player) en);
     }
     for (Player victim : nearbyPlayers) {
         if (victim.hasMetadata("isInBubble") && victim != mover) {
            Location victimLoc = victim.getLocation();
            if (victimLoc.distance(to) <= 5) {//Radius 5
                e.setCancelled(true); //Cancel so cant move
                return; //we have nothing left no need to get in for statement again
            }
            }
         }
     }
}

您可以使用元数据来设置和获取半径。关注@EventHandler.
