Get location of an entity

Hey guys. I just want one little thing. How can i get the location of a snowball when it is in air??

 

entity.getLocation()

 

@FisheyLP If i did that woulden i get all the entitys??

 

@thorvaldemar unless you're looping through all the entities in the world, then no.

 

@q8minecraft Okay i don't think i understand. Okay what i wanted to do is every time there is a snowball. The game will execute the snowball and then summon a firework at it every single tick. Do you know how that can be done??

 

@thorvaldemar Runnables, schedulers, many options.

 

@thorvaldemar
Every single tick?!?!?

Repeating task with 1 as the delay and repeats as however many. Don't know what it is? Look it up.

As for firework, you need to create the item stack and manipulate the object itself, I don't remember exactly how you do it, but you can look that up too.

 

I would suggest adding the snowball to a Set on ProjectileLaunchEvent and then having a scheduler run ever 1 tick to do the firework effect. If you need to see some code I can whip it up

 

@EvilWitchdoctor Please whip it up

 

@thorvaldemar Why are you asking for code? It won't help you with learning. Take a look at the Bukkit Javadocs here: https://hub.spigotmc.org/javadocs/bukkit/ For your event, use this:

@EvilWitchdoctor Please don't spoonfeed, it is frowned upon and doesn't help at all.

 

@henderry2019 I'm sure you are trying to help me, but i'm actully learning best by getting a code and the experince with it and this is something i've tryed to do in a long time and i was about to give up, but i would give it one more chance. Thank you for the website. I think i will find i very useful

 

wrong, no one learns like that. Do you know java?

 

Woah slow down people let's not get into a fight.
@thorvaldemar If you've never used schedulers before, here's something to look at to get you started. Obviously it will need tweaking but something generally like this ought to work to help you solve your problem

Code:

    @EventHandler
    public void onSnowballLaunch(ProjectileLaunchEvent evt){
        if(evt.getEntityType() == EntityType.SNOWBALL /*&& any other conditions*/){
            snowballList.add(evt.getEntity());
            if(snowballList.getSize() == 1) runEffectLoop();
        }
    }
   
    //somwhere else in your code
    public void runEffectLoop(){
        getServer().getScheduler().scheduleSyncDelayedTask(this, new Runnable(){
            @Override
            public void run(){
                for(Entity entity : snowballList) playFireworkEffect(entity.getLocation());
                if(!snowballList.isEmpty()) runEffectLoop();
            }
        }, 1);//runs every 1 tick
    }

 

You would do this by, Entity.getLocation();

 

If you are going to spoonfeed, at least do it right. This code makes no sense at all. Are you seriously trying to call a method within itself?

Edit: My last post got cut off, I was going to say look at this for events: http://wiki.bukkit.org/Event_API_Reference
And this for schedulers: http://wiki.bukkit.org/Scheduler_Programming

 

@henderry2019 Methods can indeed call themselves-> e.g., recursive methods. Not always the best idea to, but sometimes very useful.
Good idea posting the API refs, here's another to add to that handy list related to the topic:
https://hub.spigotmc.org/javadocs/bukkit/

 

You posted a recursive method inside a recursive method inside a for loop.

I'd be amazed if the server didn't instantly crash

 

Lol, selfown.
You flame people because you just cant understand what this really simple method does. Maybe you are the one who should take some java beginner lessons, instead of talking like a smart guy.

 

What? It wasn't inside a for loop. It was after one. It is still the wrong way to do it as he's creating a new runnable every tick rather than running a/many BukkitRunnable timer.

 

@Xerox262
Ah you're right, my mistake

Still, terrible

 

Yes i read a book.

Thanks for all the help... And yes i'm not the best to java, but i can all ways learn and not every body learns the same way. XD
