Any way to detect when a specific entity dies?

[Robin Withes]

Hey everyone,

been trying for a while to look for a solution to this problem:

 

So i am looking for certain mobs to spawn with

entitySpawned(EntityJoinWorldEvent event)

Then when i find the mob i'm looking for i want to do something like this to it:

//Obviously just a dumbed down example
	public void entitySpawned(EntityJoinWorldEvent event) {
		Entity entity = event.getEntity();
		if (true)
		{
			entity.onDead(someFunction()); //Runs when the entity dies.
		}
	}

What would be a ideal solution to this?

Capabilities. You create one, apply it to the entity when it is spawned, then in the EntityDeathEvent you check to see if that capability is there, and if so, do something.

Ah thanks, was hoping there was a cleaner way to do it but i guess not.

Is capabilities something originally from Java or from forge, i never heard of it before.

The Capabilities systems are supplied by Forge. They're an advancement on IEntityExtendedStorage (among other things)

Ah,

any chance you can send me some documentation or supply me with a code snippet?

Capabilities are a concept from Object Oriented Programming (like Objects and Interfaces). They allow for programming in the style “composition over inheritance”. Sorry for the badly worded answer, these articles explain it well.
