Cleave

I want to damage mobs around the target and call entitydamagebyentity on it, but I don't want to repeatedly cleave cleaved targets. To clarify what i mean, here's my code

Code:

public ArrayList<EntityDamageByEntityEvent> cleaveevents = new ArrayList<EntityDamageByEntityEvent>();

public void onDamage(EntityDamageByEntityEvent event){

cleaveevents.add(event);
                if(this.cleaveevents.contains(event)){
                    cleave(p,event.getEntity(),2,event.getDamage());
                   
               
                }
}

    @SuppressWarnings("deprecation")
    public void cleave(Player p, Entity target, int radius, double damage){
        for(Entity e:target.getNearbyEntities(radius, radius, radius)){
            if(e instanceof Damageable&&
                    e != target){
                ((Damageable) e).damage(damage);
            EntityDamageByEntityEvent event = new EntityDamageByEntityEvent(p, e, DamageCause.ENTITY_ATTACK, damage);
           
            Bukkit.getPluginManager().callEvent(event);
            }
            }
    }

But it is giving me this error:

The error is directed at EntityDamageByEntityEvent event = new EntityDamageByEntityEvent(p, e, DamageCause.ENTITY_ATTACK, damage);

That's another method that you didn't show

 

There's a lot of unnecessary work done here. In the bukkit api, you can use damage(double, entity) which will automatically trigger it's own entitydamagebyentityevent.

 

@Agentleader1 How does damage(double) set the damager to the player?
@megamichiel It directs to the method "cleave". I've tried it in this plain method, and it gives the same error

 

@Hex_27
Entity#damage(double amount, Entity source);

 

Moved to Bukkit Alternates.

 

Doesn't that repeat the cleave over and over again for each mob nearby?

 

@Hex_27
Could you explain to me what the whole point of cleave is? It seems to me that when an entity is damaged you damage another time so it will repeat

 

@megamichiel It's purpose is to damage all surrounding mobs, except the attacker. I also want it to trigger entitydamagebyentityevent for other purposes, but not to repeat cleave again.
