dropItem projectile not working properly

I don't know if im doing something wrong but when i fire the "gun" the projectile launches, but goes straight through the mob, sometimes damaging them but sometimes not. Also how do i make the projectile not bounce on the ground, like if it hits a block it stays at that location. If anyone knows how to fix this or a better way of doing it please let me know, thanks.

Code:

Item items =  p.getWorld().dropItem(p.getEyeLocation(), clone);
items.setVelocity(p.getLocation().getDirection().multiply(1.5));
Bukkit.getScheduler().runTaskTimer(main, new BukkitRunnable(){
        @Override
        public void run()
        {
          if(!items.isOnGround())
          {
              for(Entity en : items.getNearbyEntities(1, 1, 1))
              {
                   if(en instanceof Damageable && en != p)
                   {
                        ((Damageable) en).damage(.5);
                    }
               }
           }
           this.cancel();
          }            
}, 0L, 10L);

 

@Blackwing_Forged
You cancel the bukkit runnable after the first check. I recommend doing a Projectile Hit event and save the projectile in an ArrayList and if that projectile that was in the Projectile Hit Event is in the array list than do the damage.

 

@CommonSenze
Will that event fire? Its not technically a projectile is it?

 

@Blackwing_Forged just move the:

Code:java

this.cancel();

to the else statement:

Code:java

Bukkit.getScheduler().runTaskTimer(main, new BukkitRunnable(){
    @Override
    public void run() {
        if(!items.isOnGround()){
            for(Entity en : items.getNearbyEntities(1, 1, 1)){
                if(en instanceof Damageable && en != p){
                    ((Damageable) en).damage(.5);
                 }
            }
         } else {
            this.cancel();
         }
    }
}, 0L, 10L);

 

@CommonSenze
Still doesn't work properly, never damages mobs when i hit them and just goes right through them, i want it to when it hits a mob or block stops right where it is
