Solved Summon fireball in direction player is looking

So I want to summon a fireball that does no block damage but does set the area on fire and damages players it hits with 4 hearths. How do I do this, here is my code:

Code:

             @EventHandler
                public void onPlayerUse2(PlayerInteractEvent event){
                    Player p = event.getPlayer();         
                    if(event.getAction().equals(Action.RIGHT_CLICK_AIR)){
                        if(p.getItemInHand().getType() == Material.GOLD_SWORD){  
                           int value2 = getConfig().getInt(p.getName() + ".Permission1");
                            if(value2 == 1) {
                            if (Cooldowns.tryCooldown(p, "x2", 18000)) {
//Here i want the fireball thing
                                p.sendMessage("§b§2[Spells]:§rYou casted the Smash Spell!");
                               return;
                            }else{
                            p.sendMessage("§b§2[Spells]:§rYou have " + (Cooldowns.getCooldown(p, "x2") / 1000) + " seconds left!");

 

Use the launchProjectile method in the player instance

 

I've got this but it doesn't work what's wrong:

Code:

             @EventHandler
                public void onPlayerUse2(PlayerInteractEvent event){
                    Player p = event.getPlayer();         
                    if(event.getAction().equals(Action.RIGHT_CLICK_AIR)){
                        if(p.getItemInHand().getType() == Material.GOLD_SWORD){  
                           int value2 = getConfig().getInt(p.getName() + ".Permission1");
                            if(value2 == 1) {
                            if (Cooldowns.tryCooldown(p, "x3", 18000)) {
                                Snowball snowball = p.getWorld().spawn(p.getLocation(), Snowball.class);
                                 snowball.setVelocity(p.getLocation().getDirection().multiply(3));
                                 p.playSound(p.getLocation(), Sound.NOTE_PLING, 5, 5);



                                p.sendMessage("§b§2[Spells]:§rYou casted the Fireball Spell!");
                               return;
                            }else{
                            p.sendMessage("§b§2[Spells]:§rYou have " + (Cooldowns.getCooldown(p, "x3") / 1000) + " seconds left!");
                            return;
