Help with Event (Player hit by player event)

Heey,

So I having problems with making an event when players got hit by a player the armor contents will change how do i do this. I have tried a lot of things i will post something. below.

Code:java

 @EventHandler(priority = EventPriority.NORMAL)
public void dmg(final EntityDamageEvent event) {
Entity e = event.getEntity();
Player p = (Player)e;
 
if(p.getEquipment().getHelmet().equals(null)) {

Below the if statement, I have made a setarmor event but I dont want to share that because thats secret

If you can help me.. THANKS

ps: I have posted this somewhere else too but I cant delete that there.

 

Tried this?

Code:java

@EventHandler
public void damage(EntityDamageEvent event) {
Entity e = event.getEntity();
if (e instanceof Player){
Player p = (Player) e;
if(p.getEquipment().getHelmet().equals(null)) {
//do you secret thing
}
}
else{
//do nothing
}
}

but why checking if the player has no helmet?
just set it.

Code:java

p.getInventory().setHelmet(new ItemStack(Material.LEATHER_HELMET));
