Java 雷击事件处理

我想弄清楚，每当我扔鸡蛋时，如何让闪电击中。我的代码没有给我任何错误，但控制台是。消息仍然会弹出，但闪电不会

package me.sanfrinsisco;

import org.bukkit.entity.EntityType;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerEggThrowEvent;
import net.md_5.bungee.api.ChatColor;

public class PlayerListener implements Listener {

    public PlayerListener(EventHandling plugin) {
        plugin.getServer().getPluginManager().registerEvents(this, plugin);
    }

    @EventHandler
    public void onPickup(PlayerEggThrowEvent e) {
        Player player = e.getPlayer();

        player.sendMessage(ChatColor.DARK_BLUE + "You have summoned lightning");

        e.setHatchingType(EntityType.LIGHTNING);
        e.setNumHatches((byte) 1);
        e.setHatching(true);
    }
}

这是我在控制台中遇到的错误

正如前面所说的，你不能用卵孵化闪电。但是，我们可以使用世界和位置实现相同的效果：

@EventHandler
public void onProjectileHit(PlayerEggThrowEvent event) {
    Egg egg = event.getEgg();
    egg.getWorld().strikeLightningEffect(egg.getLocation());
    event.setHatching(false);
}

如果使用

删除效果

，闪电不会点亮任何东西，如果使用

删除效果

，则会点亮任何东西

在未来，考虑通过堆栈跟踪/错误，他们不是你的敌人，实际上是相反的！p>

这与您的问题无关，但是考虑将您的聊天色导入改为BukKeD，而不是使用BungEcRod，除非您使用BungEcOrd，否则这可能导致最终的未来问题。

<代码>：JavaLang.ILLalalAgMuMutExtExc:不能从一个卵子生成该实体类型！<代码>-看起来你不能设置卵直接孵化闪电，所以不能从卵本身孵化闪电。我将把它的位置存储在一个整数中，并在那个特定的位置生成lightning。我很确定如何去制造闪电，我已经到处找了。我也做了如下修改：“@EventHandler public void onPickup（playeregthrowevent e，Egg Egg）{Player Player=e.getPlayer（）；e.setHatching（false）；Location eggloc=Egg.getLocation（）；Player.sendMessage（ChatColor.DARK_BLUE+“You have called lightning”）；}由于某种原因，我无法格式化注释中的代码。
