NPE - Explode

So currently I'm getting an NPE on this event:

Code:java

 @EventHandler
public void wither(PlayerInteractEvent event){
Player p = event.getPlayer();
if(p.getWorld().getName().equalsIgnoreCase("pvp")){
if(p.getItemInHand().getType().equals(Material.SULPHUR)){
if(Main.playCreeper.containsKey(p.getName())){
p.getWorld().createExplosion(p.getLocation(), 9);
//Bukkit.getScheduler().scheduleSyncDelayedTask(plugin, new Runnable() {
 
// @Override
// public void run() {
 
// p.setHealth(0);
 
// }
// },5L);
}
}
}
}

The error is currently on p.getWorld().createExplosion(p.getLocation(), 9);

Can someone please help me figure out why it's reporting an NPE

 

Are your sure that it's this line, don't see here anything that can throw an NPE:

Code:

if(p.getWorld().getName().equalsIgnoreCase("pvp")){

But this line can thow an NPE:

Code:

if(p.getItemInHand().getType().equals(Material.SULPHUR)){

If the player have no item in the hand then the itemstack is null. Do a null check:

Code:

if(p.getItemInHand() != null && p.getItemInHand().getType().equals(Material.SULPHUR)){

Still getting NPE's. Same line as well.

If it helps, the explosion happens but there is absolutely no damage. I can't see the explosion but only hear it.

EDIT: Figured it out... I stupidly had a WorldGuard region set >.< Still get the NPE though, not too worried about it.
