how to launch an arrow?

i have this code but whenever the arrow launches it only goes one way... please help

Code:

@EventHandler
    public void onUse(PlayerInteractEvent e) {
        ItemStack used = e.getItem();
        Player p = e.getPlayer();
        ItemMeta usedm = used.getItemMeta();
        String name = usedm.getDisplayName();
        if (name.equalsIgnoreCase(ChatColor.MAGIC + ":::" + ChatColor.RESET
                + "" + ChatColor.GRAY + "Grappling hook" + ChatColor.RESET + ""
                + ChatColor.MAGIC + ":::")) {
            if (e.getAction().equals(Action.RIGHT_CLICK_AIR) || e.getAction().equals(Action.RIGHT_CLICK_BLOCK)) {
                Arrow a = p.getWorld().spawn(
                        e.getPlayer().getLocation()
                                .add(new Vector(0.0D, 1.0D, 0.0D)),
                                Arrow.class);
                a.setVelocity(a.getLocation().getDirection());
            }
        }
    }

 

try p.launchProjectile(Arrow.class)
And your code will throw many errors, because:

• Not all items have ItemMeta
• Not all ItemMetas have displaynames

 

@FisheyLP how would i get where the arrow landed

 

ProjectileHitEvent

But you need to add the arrows UUID or something to a List to see if it is really this arrow you want
