[1.7.10] Track type of mob killed

[Tikaji]

What I would like to do is to be able to track the number of enderman that a player had killed so that different aspects of my mod are activated. I know there are statistics that the game keeps. Would that be the best way to keep track of enderman deaths or is there another way? And if the default stat board is the best way how would I go about tying into it?

IExtendedEntityProperties to save the stat and LivingDeathEvent to change it should work.

You can use the event LivingDeathEvent and check the instanceof. For example:

 

@SubscribeEvent
public void onDeath(LivingDeathEvent event) {
	if (event.entity instanceof EntityEnderman) {
		// Increase your count here.
	}
}

 

I haven't personally been able to figure out how to check the source entity type. event.source.getEntity() only returns null (seriously, it's hard coded in).

Actually, event.source.getEntity() doesn't always return null.

Ok I lied when I said this was solved. I tried out the code above and I didn't get the result I wanted when I put the count into the log. It didn't display when an enderman was killed. I'm not sure if i did something wrong or not. I'm fairly new to modding and may not understand how these events work. Do I need to call the class in the main mod class so that it begins counting or am I missing something?

 

Sorry about that. Gotta love the new guys right?

It is easy to think that because DamageSource#getEntity() method always returns null.  What you need to consider though is that there are other classes that extend DamageSource, such as EntityDamageSource, that can be passed as the event.source (because these extended classes are valid DamageSource classes).  EntityDamageSource returns the entity in the getEntity() method.

 

It is an important thing to remember in Java (and similar languages) -- when a method parameter has a type, you need to consider that any of the subtypes of that type are also valid to pass in.

DamageSource#getEntity() will always return the root entity if there was one. For any damage source like an arrow or a snowball or sword to the skull. It may even work with TNT planted by a person. I haven't checked that. (getSourceOfDamage() will return the arrow or snowball or whathavevou entity)
