Toggle on/off with command HELP!

i made a plugin but i want when a player type a command it will turn on,and if he type it again it will turn off... but the problem is that i know how to toggle but its a
@EventHandler
public void onPlayerToggleFlight(PlayerToggleFlightEvent event) {

event..and i cant figure out how it works...

 

Code:

if sender is player
  if player can fly
    disable fly
  else
    enable fly

There, toggle flight command

 

can i pm my class?
would be easier for you to see what i make

 

Why pm it? Post it here, trust me, no one is going to steal your original idea of a toggle fly command.

 

haha i know but still tho

Code:

    @EventHandler
    public void onPlayerToggleFlight(PlayerToggleFlightEvent event) {
        final Player player = event.getPlayer();

        if (player.getGameMode().equals(GameMode.CREATIVE))
            return;
        if (!(player.hasPermission("dj.doublejump")))
            return;
        if (cooldownTime.containsKey(player.getName())) {
            event.setCancelled(true);
            return;
        }

        event.setCancelled(true);
        player.setAllowFlight(true);
        player.setFlying(false);
        player.setVelocity(player.getLocation().getDirection().multiply(1.5).setY(1));
        event.getPlayer().setNoDamageTicks(100);

        cooldownTime.put(player.getName(), getConfig().getInt("cooldown") * 20);
        if (getConfig().getBoolean("messageadd"))
            player.sendMessage(format(getConfig().getString("cooldownadd")));
        player.setAllowFlight(false);

        cooldownTask.put(player.getName(), Bukkit.getScheduler().runTaskTimer(this, new Runnable() {
            public void run() {
                int time = cooldownTime.get(player.getName());
                time -= 1;
                if (time <= 0) {
                    cooldownTime.remove(player.getName());
                    if (getConfig().getBoolean("messageremove")) {
                        player.sendMessage(format(getConfig().getString("cooldownremove")));
                    }
                    BukkitTask task = cooldownTask.get(player.getName());
                    cooldownTask.remove(player.getName());
                    task.cancel();
                } else {
                    cooldownTime.put(player.getName(), time);
                }
            }
        }, 1l, 1l));

here ya go,its not like you think it it,it has more in the class itself but this is the part where it has to be

 

@PeterXonwiiXx
Instead of creating a variable, and then going through THREE checks to see if you can even use it, check first, and then create the player variable.

Why do you give the player flight, and then NANOSECONDS later you take it away?

Instead of -=1; just use --;

Why are you going to repeat that task every tick?

 

its for double jump plugin when a player has permission,what i have here works fine...i only need something that i can toggle this in a command

 

Create a collection of the players that are exempt from double jumping, in the command add/remove them depending on what they need and in the event check if they're in the collection.
