我的LightningShot文件

package me.Pixel;

import org.bukkit.scheduler.BukkitRunnable;

public class LightningShot extends BukkitRunnable {
    private Arrow arrow;
    private int tick = 1;

    public LightningShot(Arrow arrow) {
        this.arrow = arrow;
    }

    @Override
    public void run() {
        if (arrow == null || arrow.isOnGround() || tick++ > 20 * 10) {
            this.cancel();
        } else {
            arrow.getWorld().strikeLightning(arrow.getLocation());
        }
    }
}

所以我希望你能帮助我让它发挥作用。这是所有新代码。

Answer 1

如果你想检查Bow，箭头射出是否是“魔法弓”，你可以在ItemStack：EntityShootBowEvent获得弓箭的event.getBow()。现在，您可以查看事件中弓的名称是否等于您在“/ bow”命令中给予玩家的弓的名称。

希望这可以帮助你:)抱歉我的英语不好; D

            ItemStack bow = ev.getBow();
            if (bow.hasItemMeta() && bow.getItemMeta().getDisplayName().equals(ChatColor.AQUA + "Magic" + ChatColor.RED + "Bow")) {

        }
    }
}

LightningShot.java：

package me.Pixel;

import org.bukkit.Bukkit;
import org.bukkit.Location;
import org.bukkit.entity.Arrow;
import org.bukkit.scheduler.BukkitTask;

public class LightningShot {
    private static int interval = 5;

    Arrow arrow;
    int tick = interval;

    public LightningShot(Arrow a) {
        arrow = a;

        BukkitTask[] task = new BukkitTask[1];
        task[0] = Bukkit.getScheduler().runTaskTimerAsynchronously(Main.plugin, new Runnable() {
            @Override
            public void run() {
                if (arrow == null || arrow.isOnGround() || arrow.isDead() || tick >= 200) {
                    System.out.println("Stopping...");
                    task[0].cancel();
                } else {
                    tick += interval;
                    System.out.println("Launching Lightning...");
                    Location loc = arrow.getLocation();
                    System.out.println("At " + loc.getWorld().getName() + " " + loc.getX() + "/"+ loc.getY() + "/" + loc.getZ());
                    loc.getWorld().strikeLightning(arrow.getLocation());
                }
            }
        }, interval, interval);
    }
}

EntityShootBowEvent：

@EventHandler
public void onEntityShootBow(EntityShootBowEvent ev) {
    if (ev.getProjectile() instanceof Arrow) {
        Arrow a = (Arrow) ev.getProjectile();
        if (a.getShooter() instanceof Player) {
            System.out.println("Launching LightningShot...");
            new LightningShot(a);
        }
    }
}

您可以更改间隔以更改闪电产生的频率。

两者都是我使用过的完整课程，并且有效...
