Entity Collision Event?

Hi guys!
I have recently been working on a plugin that will fire exploding pigs from a special wand . SO, I need to figure out how to detect when the pigs actually collide with a block. I currently use the EntityDamageEvent to detect fall damage, but fall damage isn't always caused resulting in "Pigs of doom" just walking around!

My code:

Code:

@Override
public boolean use(Player p) {
p.sendMessage("Wand fired!");
final Vector dir = p.getEyeLocation().getDirection().multiply(2);
Pig proj = (Pig) p.getWorld().spawn(p.getEyeLocation().add(dir.getX(), dir.getY(), dir.getZ()), Pig.class);
proj.setCustomName(""+ChatColor.RESET+ChatColor.RED+"Pig of Doom");
proj.setCustomNameVisible(true);
proj.setVelocity(dir);
listofpigs.add(proj.getEntityId());
return true;
}
 
@EventHandler
public void onEntityDamageEvent(EntityDamageEvent e) {
if (listofpigs.contains(e.getEntity().getEntityId())) {
Pig pig = (Pig) e.getEntity();
listofpigs.remove(new Integer(pig.getEntityId()));
pig.setHealth(0);
e.getEntity().getWorld().createExplosion(e.getEntity().getLocation().getX(), e.getEntity().getLocation().getY(), e.getEntity().getLocation().getZ(), 4, false, false);
}
}

Btw, the "use(Player p)" method is called with the PlayerInteractEvent.

Thanks in advanced!

 

What about tag the pigs and make a task that runs every tick(2 ticks if you want).
And checks the location the pig is in and check if its location is touching any other blocks.

 

I considered this, but I was worried that it will lag too much... Any other ideas? (If not I may be forced to use that)

 

afaik the lag wouldn't be bad as long as your check was quick.

If you launch the pigs at great velocity, they will receive damage whenever they hit something solid.

 

Uuuunless its a wall.

If you launch them at a great velocity, they will receive damage since they hit it so darn hard.

EDIT:
Haha, oh sorry. I'm gonna blame it on being tired. I temporarily forgot that minecraft doesn't deal damage that way.

Yea I realized this directly after I posted my response, check the edit

It seems I would create even greater lag if I don't use the scheduler, so that is what I am going to be stuck with. Thanks!

 

you can spawn an arrow, and set the pig as passengier, if the location of the combination stays the same, it must have hit something solid
