Bukkit 1.20.1 SuperiorSkyblock2 API 玩家掉落虚空自动拉回出生点功能

以下是使用Java编写的基于SuperiorSkyblock2的API实现玩家掉落虚空自动拉回出生点功能的示例代码：

import org.bukkit.Bukkit;
import org.bukkit.Location;
import org.bukkit.World;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.EntityDamageEvent;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.plugin.java.JavaPlugin;
import com.bgsoftware.superiorskyblock.api.SuperiorSkyblockAPI;
import com.bgsoftware.superiorskyblock.api.island.Island;

public class VoidFallListener implements Listener {
    private JavaPlugin plugin;

    public VoidFallListener(JavaPlugin plugin) {
        this.plugin = plugin;
    }

    @EventHandler
    public void onPlayerFallIntoVoid(EntityDamageEvent event) {
        if (!(event.getEntity() instanceof Player)) {
            return;
        }

        Player player = (Player) event.getEntity();
        if (event.getCause() == EntityDamageEvent.DamageCause.VOID) {
            Island island = SuperiorSkyblockAPI.getIslandAt(player.getLocation());
            if (island != null && island.getOwner() == player.getUniqueId()) {
                Location spawnLocation = getIslandSpawnLocation(island);
                if (spawnLocation != null) {
                    Bukkit.getScheduler().runTask(plugin, () -> {
                        player.teleport(spawnLocation);
                    });
                }
            }
        }
    }

    @EventHandler
    public void onPlayerJoin(PlayerJoinEvent event) {
        Player player = event.getPlayer();
        Island island = SuperiorSkyblockAPI.getIslandAt(player.getLocation());
        if (island != null && island.getOwner() == player.getUniqueId()) {
            Location spawnLocation = getIslandSpawnLocation(island);
            if (spawnLocation != null) {
                player.teleport(spawnLocation);
            }
        }
    }

    private Location getIslandSpawnLocation(Island island) {
        World world = Bukkit.getWorld(island.getWorldName());
        if (world != null) {
            return new Location(world, island.getCenter().getX(), island.getCenter().getY(), island.getCenter().getZ());
        }
        return null;
    }
}

public class Main extends JavaPlugin {
    @Override
    public void onEnable() {
        getServer().getPluginManager().registerEvents(new VoidFallListener(this), this);
    }
}

请注意，上述代码假设你已经正确安装和配置了SuperiorSkyblock2插件，并且已经将其API添加到你的项目中。如果你还没有完成这些步骤，请确保按照SuperiorSkyblock2文档中的说明进行操作。

此代码在玩家掉入虚空时检查其所在的岛屿所有权，并将其传送回该岛屿的出生点。此外，当玩家加入服务器时，它还会检查其所在的岛屿并将其传送回出生点。
