Solved If a player toggles sneak, allow him to get a "powerup" for X seconds...

Hello everyone,

I am trying to make a plugin that if a player toggles sneak (taps shift,) he can get a "powerup" with PlayerInteractEvent for X amount of time. For example, if the player taps sneak, he will enter into a powered up mode and be able to fire multiple snowballs (as opposed to only 1) for 5 seconds.

Here is what I have been goofing around with:

Did the player sneak?

Code:

    @EventHandler
    public void onSneak(PlayerToggleSneakEvent event)
    {
        if(event.getPlayer().isSneaking())
        {
            isSneak = true;
            event.getPlayer().sendMessage("isSneak = true;");
        }
        if(!event.getPlayer().isSneaking())
        {
            isSneak = false;
            event.getPlayer().sendMessage("isSneak = false;");
        }
    }

If the player tapped sneak, he can has the powerup for 5 seconds:

Code:

@EventHandler
public void activatePowerupIfToggledSneak(PlayerInteractEvent event)
    {
        if(!isSneak)  /* isSneaking() returns false if the player is crouched..I think..
                                this is where the main issue is, because as soon as a player unsneaks,
                                this is set to true. At the same time I can't do a while(!isSneaking()) because
                                I want just tapping sneak to activate this, not holding it down
        {
            //Activate a "powerup"
            if(event.getAction() == Action.RIGHT_CLICK_AIR && event.getPlayer().getItemInHand().getTypeId() == 332)
            {
                Player player = event.getPlayer();
                //some code to shoot 10 snowballs at once instead of 1
            }
            plugin.getServer().getScheduler().scheduleSyncDelayedTask(plugin, new Runnable() {
                public void run()
                {               
                    //after 5 seconds disable this "powerup"
                } }, 20 * 5);
        }
    }
    

Any idea on how to go about this? I don't know if it is blatantly obvious and I am just really tired...I can't figure out how to make tapping sneak activate the ability without having to hold down sneak. I suppose I would also need some scheduler to allow the player to use this ability AGAIN after X seconds, but I can figure that out most likely.

Thanks in advance!

 

You're on the right track, but I wrote an example of this:

Code:

    public static Map<String, Integer> sneaks = new HashMap<String, Integer>();
    public static Set<String> cantsneak = new HashSet<String>();
    @EventHandler
    public void onPlayerSneak(final PlayerToggleSneakEvent e){
        if(e.isSneaking()) return;
        if(sneaks.containsKey(e.getPlayer().getName())){
            Bukkit.getScheduler().cancelTask(sneaks.get(e.getPlayer().getName()));
            sneaks.remove(e.getPlayer().getName());
            e.getPlayer().sendMessage(ChatColor.GOLD+"Powerup deactivated!");
            cantsneak.add(e.getPlayer().getName());
            Bukkit.getScheduler().scheduleSyncDelayedTask(new Main(), new Runnable(){
                @Override
                public void run() {
                    Listeners.cantsneak.remove(e.getPlayer().getName());
                }
            }, 100L);
            return;
        }
        if(cantsneak.contains(e.getPlayer().getName())){
            e.getPlayer().sendMessage(ChatColor.RED+"Your cooldown isnt done yet!");
            return;
        }
        sneaks.put(e.getPlayer().getName(), Bukkit.getScheduler().scheduleSyncDelayedTask(new Main(), new Runnable(){
            @Override
            public void run() {
                Listeners.sneaks.remove(e.getPlayer().getName());
                e.getPlayer().sendMessage(ChatColor.GOLD+"Powerup deactivated!");
                cantsneak.add(e.getPlayer().getName());
                Bukkit.getScheduler().scheduleSyncDelayedTask(new Main(), new Runnable(){
                    @Override
                    public void run() {
                        Listeners.cantsneak.remove(e.getPlayer().getName());
                    }
                }, 100L);
            }
        }, 100L));
        e.getPlayer().sendMessage(ChatColor.GOLD+"Powerup activated!");
    }
    @EventHandler
    public void onPlayerInteract(PlayerInteractEvent e){
        if(sneaks.containsKey(e.getPlayer().getName()) && e.getAction() == Action.RIGHT_CLICK_AIR && e.getPlayer().getItemInHand().getTypeId() == 332){
            for(int i=0;i<4;i++) e.getPlayer().throwSnowball();
        }
    }

You can follow the process to see how it works. As far as I tested, it works just fine. I set the cool-down of the power-up to 5 seconds.

 

Don't use a runnable, capture system time with System.currentTimeMillis(), add to a map, compare.

 

That would work too.

 

Superckl1 Wow! Thanks a ton man! Sorry for my delayed reply. I got 1 question I am going to PM you about if you don't mind.

Tirelessly Why is it that you recommend System.currentTimeMillis()? Just wondering, I am new to Java and programming as a whole

 

Less overhead than creating a bunch of tasks.
