bukkitEntity Events

Introduction

All Entity Events extends EntityEvent, the superclass for EntityEvents.

All known EntityEvents can be found below, and will be covered in this documentation.

EntityDamage Event

The EntityDamage event is thrown when an Entity is damaged.

EntityDamageEvent

@EventHandler
public void onEntityDamage(EntityDamageEvent e) {
    DamageCause cause = e.getCause();    //Get the event DamageCause
    double rawDamage = e.getDamage();    //Returns the damage before any calculation
    double damageModified = e.getDamage(DamageModifier.X);     //Returns the damage that would be caused with the specified modifier
    double finalDamage = e.getFinalDamage();    //Gets the final damage of this event, with all the calculations included

    e.setCancelled(boolean x);    //If for any reasons you want the event to not happen, you can cancel it
    e.setDamage(double damage);    //You can change the full damage the event will cause
    e.setDamage(DamageModifier modifier, double damage);    //Changes the damage considering any possible modifier
}

Most of the times, the EntityDamageEvent will not be used. Instead, one of it's subclasses will be used, such as EntityDamageByEntityEvent or EntityDamageByBlockEvent. Both can be seen below.


EntityDamageByEntityEvent

@EventHandler
public void onEntityDamageByEntity(EntityDamageByEntityEvent e) {
    //Retrieving the Entity that dealt damage
    Entity damageDealer = e.getDamager();

    //Retrieving the Entity that took damage
    Entity damageTaker = e.getEntity();

    //Retrieving the cause of the damage
    DamageCause cause = e.getDamageCause();

    //damage is the double value of the damage before all the resistances and modifiers have been applied
    double damage = e.getDamage();

    //FinalDamage is the double value of the damage after all the resistances and modifiers have been applied
    double finalDamage = e.getFinalDamage();

   //You can also set the raw damage (before modifiers) for the event to a different value
   e.setDamage(20.0);
}

EntityDamageByBlockEvent

A simple extension to the EntityDamageEvent, but with one different method:

Block b = event.getDamager();    //Returns the block that dealt damage to the entity
