How do I get the arrow (ItemStack) shot by a bow

Hello,

I was wondering if there was a way to get the arrow (in itemstack) that was shot by a bow im using the EntityShootBowEvent and checking if the projectile is an arrow and if the entity is a player here is my current code

Code:java

    @EventHandler
    public void shootArrowEvent(EntityShootBowEvent event){
        if(event.getProjectile() instanceof Arrow){
            if(event.getEntity() instanceof Player){
                ItemStack bow = event.getBow();
                Arrow arrow = (Arrow) event.getProjectile();
                if(bow.getItemMeta().hasDisplayName()){
                    if(bow.getItemMeta().getDisplayName().equals("explosion")){
                        setMetaData(arrow, "explosion", false);
                    }
                }
            }
        }
    }
 
    @SuppressWarnings("deprecation")
    @EventHandler
    public void onProjectileHit(ProjectileHitEvent  event)
    {
        if(event.getEntity() instanceof Arrow)
        {
            if(event.getEntity().getShooter() instanceof Player)
            {
                Arrow arrow = (Arrow) event.getEntity();
                World world = arrow.getLocation().getWorld();
                Location location = arrow.getLocation();
                if(hasMetadata(arrow, "explosion")){
                    world.createExplosion(location, 3);
                    arrow.remove();
                }
                else
                {
                    if(arrow.getFireTicks() > 0)
                    {
                        Block block = location.getBlock();
                        block.setType(Material.FIRE);
                        arrow.remove();
                    }
                }
            }
        }
    }

I want to set the metadata on what arrow was shot not the name of the bow because people could just rename there bow also I would like to do the same with fire like if the arrow has a metadata called "fire" then when it hits the ground makes fire. Would it be possible to get the itemstack and how ??

 

So, just to be clear - the code you post above is how you are doing it now, but you don't want to do that and instead you want to set meta data for arrows that indicate that they are explosive arrows or fire arrows?

 

Jack Price-Burns use lore, it can't be changed by player

Unless you place it as a block. Everything is removed then, I think.

A bow is an item... Not a placeable block.

Well, yeah, but it's worth noting for future reference.

Metadata is better, especially if you don't need the data being visible to the player (If you have casted the arrow to it's MaterialData type (Arrow) then you can use arrow.setMetadata()

Using the entity shoot bow event I would like to get the arrow that was shot not the projectile the item this is so I can check various things about it like the name the metadata or lores

 

There's only one way to do this and its not pretty or performant. You need to listen for the PlayerInteractEvent first, during that event, if the player has a bow in their hand, you need to find all Arrow ItemStacks in their inventory and save them somewhere for comparison. Then when they EntityShootBowEvent fires, you check their inventory again and compare the stacks to see which one is missing an arrow. It's probably going to have a noticable performance impact. but there's no other way to accomplish this.

Oh man dat system thanks for the advice if I find anything out il post it here.

 

*Bump*

I was talking to one of my friends about this issue and he is really good at java he told me there is a way of doing this via NMS or something and this requires overriding a minecraft class file to make the arrow that is removed into a getArrowUsed() function could anyone who knows what he is talking about give me an example of this. My friend said he wont tell me because I wont learn anything from him telling me but also he gives me no help what so ever in trying to find the answer.
