java - 在 Bukkit 的骷髅马周围生成生物刷怪器粒子

Question

嘿，所以我只是想在 Minecraft 中让一匹骷髅马不断地围绕着它周围的生物生成器粒子。我无法弄清楚如何循环它以使其不断产生火焰粒子。到目前为止我所做的如下。

package survivalcraft.FireHorse;
import java.util.logging.Logger;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.plugin.PluginDescriptionFile;
import org.bukkit.command.CommandSender;
import org.bukkit.command.Command;
import org.bukkit.entity.EntityType;
import org.bukkit.entity.Horse.Variant;
import org.bukkit.entity.Player;
import org.bukkit.entity.Horse;
import org.bukkit.Effect;

public class Main extends JavaPlugin{
    public static Main plugin;
    public final Logger logger = Logger.getLogger("Minecraft");

    @Override
    public void onDisable(){
        PluginDescriptionFile pdf = this.getDescription();
        this.logger.info(pdf.getName() + " version " + pdf.getVersion() + " has been disabled! Neigh! ;D");
    }

    @Override
    public void onEnable(){
        PluginDescriptionFile pdf = this.getDescription();
        this.logger.info(pdf.getName() + " version " + pdf.getVersion() + " has been enabled!");
    }

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){
        Player player = (Player) sender;
        if(commandLabel.equalsIgnoreCase("firehorse") || commandLabel.equalsIgnoreCase("fh")){
            Horse horse = (Horse) player.getWorld().spawnEntity(player.getLocation(), EntityType.HORSE);
            horse.setBreed(true);
            horse.setAdult();
            horse.setVariant(Variant.SKELETON_HORSE);
            horse.setCustomName(player.getDisplayName() + "'s Fire Horse");
            horse.getWorld().playEffect(horse.getLocation(), Effect.MOBSPAWNER_FLAMES, 0);
        }
        return false;
    }   
}

Answer 1

考虑使用 Scheduler Programming .您可以创建一个重复任务，每隔几个刻度生成一次粒子:

getServer().getScheduler().runTaskTimer(this, new Runnable() {
    public void run() {
        horse.getWorld().playEffect(horse.getLocation(), Effect.MOBSPAWNER_FLAMES, 0);
    }
}, 0L, 10L);

只需用它替换当前的 playEffect 行，并使 horse 成为最终的。
