How to find out the damage cause

I'm trying to make it so something only happens if the damage cause was a certain type (such as lava damage). What I'm using right now is:

Code:

if (DamageCause.LAVA != null) {
//do something
}

However, the "//do something" code is ran no matter what the damage type is. This is in an EntityDamageEvent Listener.

 

Your general understanding of this kind of code is wrong.
DamageCause is and enum, which means that DamageCause.LAVA can never be null.

What you are probably looking for here is the following:

Code:

@EventHandler
public void onEntityDamage(EntityDamageEvent event) {
    if (event.getCause() == DamageCause.LAVA) {
        //do something
    }
}

I hope this helps you. =D

 

Ah, perfect. Thanks!
