Fireball direction not changing

I'm getting all nearby fireball with .getNearbyEntities() and multiplying their direction by -1. When this happens, the fireball will go in the opposite direction then, in mid flight, go back to original direction! How to I stop the fireball from going back the original direction?

P.S. When I say fireball, I mean both big and small.

Code:

Code:java

@EventHandler
public void deflector(PlayerInteractEvent e) {
 
final Player player = e.getPlayer();
List<Entity> entity = player.getNearbyEntities(3.9, 3.9, 3.9);
 
if (player.getItemInHand() != null && player.getItemInHand().getType() != Material.AIR) {
if (player.getItemInHand().hasItemMeta() && player.getItemInHand().getItemMeta().hasDisplayName()) {
if (player.getItemInHand().getType() == Material.CLAY_BALL && player.getInventory().getItemInHand().getItemMeta().getDisplayName().equalsIgnoreCase("§4Deflector Stone") && e.getAction() == e.getAction().RIGHT_CLICK_AIR || player.getItemInHand().getType() == Material.CLAY_BALL && player.getInventory().getItemInHand().getItemMeta().getDisplayName().equalsIgnoreCase("§4Deflector Stone") && e.getAction() == e.getAction().RIGHT_CLICK_BLOCK) {
if (player.hasPermission("use.deflectorstone")) {
for (final Entity x: entity) {
if (x instanceof Projectile) {
if (!(x instanceof WitherSkull) && x.isInsideVehicle() == false) {
final Vector velocity = x.getVelocity();
final Vector direction = x.getLocation().getDirection();
final WitherSkull wither = x.getWorld().spawn(x.getLocation(), WitherSkull.class);
player.sendMessage(direction.toString());
wither.setDirection(new Vector(0, 0, 0));
wither.setVelocity(new Vector(0, 0, 0));
wither.setPassenger(x);
//x.remove();
Bukkit.getScheduler().scheduleSyncDelayedTask(plugin, new Runnable() {
public void run() {
wither.remove();
Vector dir = direction.multiply(-1);
if (!(x instanceof SmallFireball)) {
Vector vel = velocity.multiply(-1);
x.setVelocity(vel);
player.sendMessage("phail");
}
player.sendMessage(x.getLocation().setDirection(dir).toString());
x.getLocation().setDirection(dir);
}
}, 150L);
}
}
}
}
}
}
}
}

Try this:

Code:java

@EventHandler
    public void deflector(PlayerInteractEvent e) {
 
        final Player player = e.getPlayer();
        List<Entity> entity = player.getNearbyEntities(3.9, 3.9, 3.9);
 
        if (player.hasPermission("use.deflectorstone") && hasDeflectorStone(player)
                && (e.getAction() == e.getAction().RIGHT_CLICK_BLOCK || e.getAction() == e.getAction().RIGHT_CLICK_AIR)) {
            for (final Entity x : entity) {
                if (x instanceof Projectile) {
                    if (!(x instanceof WitherSkull) && x.isInsideVehicle() == false) {
                        final Vector velocity = x.getVelocity();
                        final Vector direction = x.getLocation().getDirection();
                        final WitherSkull wither = x.getWorld().spawn(x.getLocation(), WitherSkull.class);
                        player.sendMessage(direction.toString());
                        wither.setDirection(new Vector(0, 0, 0));
                        wither.setVelocity(new Vector(0, 0, 0));
                        wither.setPassenger(x);
                        // x.remove();
                        Bukkit.getScheduler().scheduleSyncDelayedTask(plugin, new Runnable() {
                            public void run() {
                                wither.remove();
                                Vector dir = direction.multiply(-1);
                                if (!(x instanceof SmallFireball)) {
                                    Vector vel = velocity.multiply(-1);
                                    x.setVelocity(vel);
                                    player.sendMessage("phail");
                                }
                                player.sendMessage(x.getLocation().setDirection(dir).toString());
                                x.getLocation().setDirection(dir);
                            }
                        }, 150L);
                    }
                }
            }
        }
 
    }
 
    public boolean hasDeflectorStone(Player player) {
        if (player.getItemInHand() != null && player.getItemInHand().getType() != Material.AIR) {
            if (player.getItemInHand().hasItemMeta() && player.getItemInHand().getItemMeta().hasDisplayName()) {
                if (player.getItemInHand().getType() == Material.CLAY_BALL
                        && player.getInventory().getItemInHand().getItemMeta().getDisplayName().equalsIgnoreCase("§4Deflector Stone")) {
                    return true;
                }
            }
        }
        return false;
    }

If it doesn't work, then please provide these details:
1. What are you expecting to happen ?
2. What do you observe happening ? (when you test it)

Thanks, Good luck!

 

I want the fireball to go the opposite direction it was originally going. There are no console errors
