Solved Prevent damage to players and Villagers

I need preventing players from causing damage to other players and villagers, also if players are in the array can not attack. But it returns me nullpointerException error in the line " if (entity.getLastDamageCause().getEntity() instanceof Player) {"

May which be the error?

Code:java

@EventHandler
public void onEntityDamage(EntityDamageByEntityEvent event) {
 
LivingEntity entity = (LivingEntity)event.getEntity();
 
if (entity.getLastDamageCause().getEntity() instanceof Player) {
event.setCancelled(true);
} else if(event.getEntityType() == EntityType.VILLAGER) {
event.setCancelled(true);
} else {
Player player = (Player) event.getDamager();
if(Spectators.contains(player.getName())) {
event.setCancelled(true);
}
 
}
}

You'll be looking at...

if (event.getDamager() istanceof Player)

To see if the player is what did the damage.

After that you'll be having to do..

if (event.getEntity() instanceof Villager)

to see if it's a villager that was hit.

 

Oh, thanks. Solved
