event.getEntity() problems.

Code:

               if (event.getEntity() != null)
               {
                   System.out.println( event.getEntity().getClass().getName() );

               }

That's inside of an onEntityExplode event, and only Creeper explosions are appearing.

I need to differentiate between Creepers, TNT, and Ghast Fireballs. How could I go about this?

 

event.getEntity() returns a null entity for TNT and GhastFireballs. It doesn't for creepers.
That's about the only 'propper' detection you can do as far as I know.

 

So I've noticed. It shouldn't be doing that as far as I know.

Is there any other possible way to differentiate between the three?

 

You could use the ExplosionPrimedEvent.
It is called when the creeper/TNT/fireball actually explodes, but before block/player damage is done.

You can then use:

Code:

if(event.getEntity() instanceof TNTPrimed)

if(event.getEntity() instanceof Creeper)

if(event.getEntity() instanceof Fireball)

 

Would cancelling this event also cancel the world damage?

 

Yes. It prevents the explosion entirely. If you cancel an ExplosionPrimedEvent the EntityExplodeEvent will never be called either.

 

Thank you! With your help, I managed to whip this together.

Code:

       public void onExplosionPrimed(ExplosionPrimedEvent event)
       {
               if (event.getEntity() != null)
               {
                   if (event.getEntity().getClass().getName().contains("CraftCreeper"))
                   {
                       event.getEntity().remove();
                       event.setCancelled(true);
                       return;
                   }

                   if (event.getEntity().getClass().getName().contains("CraftFireball"))
                   {
                       event.getEntity().remove();
                       event.setCancelled(true);
                       return;
                   }

               }
               return;
       }

 

It would be cleaner (and more efficient) to use instanceof like Edward proposed:

Code:

  public void onExplosionPrimed(ExplosionPrimedEvent event)
       {
               if (event.getEntity() != null)
               {
                   if (event.getEntity() instanceof Creeper)
                   {
                       event.getEntity().remove();
                       event.setCancelled(true);
                       return;
                   }

                   if (event.getEntity() instanceof Fireball)
                   {
                       event.getEntity().remove();
                       event.setCancelled(true);
                       return;
                   }

               }
               return;
       }
