How can i make a disable command as the same as the enable command?

Hi there developers! I wanna make a core/custom essentials but it's hard to make the /fly

I wanna make that if i am not flying when i type /fly and i fly. But when i am flying then when i type /fly
it will deactivate How do i?


Code:

Code:

package me.niblaplayz.fly;

import org.bukkit.ChatColor;
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 {

    String igprefix = "[Flight]";
    String consoleprefix = "[Flight]";
   
    public void onEnable() {
        System.out.println(consoleprefix + "Aktivert");
    }
   
    public void onDisable() {
        System.out.println(consoleprefix + "Deaktivert");
    }
   
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
       
        Player p = (Player) sender;
       
        if (commandLabel.equalsIgnoreCase("fly")) {
            p.sendMessage(ChatColor.GREEN + "[NiblaFly]" + " FlyModus Aktivert");
            p.setAllowFlight(true);
        }
        else if (commandLabel.equalsIgnoreCase("fly")){
            p.sendMessage(ChatColor.GREEN + "[NiblaFly]" + ChatColor.RED + " FlyModus Deaktivert");
            p.setAllowFlight(false);
        }
       
        return true;
       
    }
   
}

plugin.yml:

Code:

name: FlyModus
version: 1.0
main: me.niblaplayz.fly.Main
author: niblaplayz
description: Du kan fly

commands:
     fly:
         usage: /<command>
         description: Gjør så du kan fly

 

How do i?

 

Use org.bukkit.entity.Player#isFlying and org.bukkit.entity.Player#setFlying:

Code:

Player p; // Your player
p.setFlying(!p.isFlying()); // Invert flying

or

Code:

Player p; // Your player
if(p.isFlying()) {
    p.setFlying(false);
    p.sendMessage(ChatColor.RED+"Flying disabled");
} else {
    p.setFlying(true);
    p.sendMessage(ChatColor.GREEN+"Flying enabled");
}
