“我的世界”禁用飞行

Question

我们的目标是在玩家输入/fly时启用飞行，并在玩家输入/dfly时禁用它，但当我输入/dfly时什么也不会发生。

    package ts.fl.me;

import org.bukkit.Bukkit;
import org.bukkit.Color;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin {
    public void onEnable() {
        getLogger().info("plugin started yaya");
    }

    public void onDisable() {
        getLogger().info("plugin stoped:(");
    }

    public boolean onCommand(CommandSender sender, Command cmd, String lable, String args[]) {
        if (sender instanceof Player) {
            Player player = (Player) sender;
            if (cmd.getName().equalsIgnoreCase("fly")) {
                String fly = "fly " + player.getName();
                Bukkit.dispatchCommand(Bukkit.getConsoleSender(), fly);
                player.setAllowFlight(true);
                player.setFlying(true);
                player.sendMessage(Color.RED + "you are now flying mate");
            }

        }
        if (sender instanceof Player) {
            Player player = (Player) sender;
            if (cmd.getName().equalsIgnoreCase("dfly")) {
                if(player.isFlying()){
                    String dfly = "dfly " + player.getName();
                    Bukkit.dispatchCommand(Bukkit.getConsoleSender(), dfly);
                    player.setAllowFlight(false);
                    player.setFlying(false);
                    player.sendMessage("you are no longer flying!");

                }
            }

        }
        return false;

    }


}

Answer 1

对于dfly命令(根据您的代码)，只有当玩家当前正在积极飞行时，其飞行权限才会被撤销。因此，如果玩家没有飞行(例如在地面上)，但有飞行的能力，dfly命令不会做任何事情，这就是我假设你在使用该命令时什么都不会发生的意思。

如果您打算让dfly命令也取消玩家的飞行权限，即使他们当前没有飞行(但有这样做的能力)，您可以简单地删除"if (player.isFlying())“条件。这将反映fly命令的相同行为，该命令在授予玩家权限之前不会检查玩家当前是否正在飞行。

我只是给出一个我做的例子：

@SuppressWarnings("rawtypes")
public boolean onCommandFly(CommandSender sender, Command cmd, String label, String[] args) {
    if (label.equalsIgnoreCase("fly")) { 
        Player p = (Player) sender;
        if(sender instanceof Player) {
            if(p.hasPermission("smpenhance.fly")) {
                if(args.length == 1) {
                    if (args.length > 1) {
                        p.sendMessage(prefix + ChatColor.translateAlternateColorCodes('&', prefix + " &fToo many arguments!"));
                    } else {
                        if(p.isFlying() == true) {
                            Player po = Bukkit.getPlayer(args[0]);
                            po.setAllowFlight(false);
                            po.setFlying(false);
                            p.sendMessage(ChatColor.translateAlternateColorCodes('&', prefix + " &fFlight disabled for &b" + po + "&r"));
                        } else {
                            Player po = Bukkit.getPlayer(args[0]);
                            po.setAllowFlight(true);
                            po.setFlying(true);
                            p.sendMessage(ChatColor.translateAlternateColorCodes('&', prefix + " &fFlight enabled for &b" + po + "&r"));
                        }
                    }
                } else {
                    if(p.isFlying() == true) {
                        p.setAllowFlight(false);
                        p.setFlying(false);
                        p.sendMessage(ChatColor.translateAlternateColorCodes('&', prefix + " &fFlight disabled"));
                    } else {
                        p.setAllowFlight(true);
                        p.setFlying(true);
                        p.sendMessage(ChatColor.translateAlternateColorCodes('&', prefix + " &fFlight enabled"));
                    }
                    p.setAllowFlight(true);
                    p.setFlying(true);
                    p.sendMessage(ChatColor.translateAlternateColorCodes('&', prefix + " &fFlight enabled"));
                }
                
                
            } else {
                p.sendMessage(ChatColor.translateAlternateColorCodes('&', prefix + " &4&lSORRY BUT NO PERMS DUDE!"));
            }
        } else {
            System.out.println(prefix + ChatColor.translateAlternateColorCodes('&', "&4Player only command!"));
        }
    }
    return false;
}
