So I have this here event handler method…

@SubscribeEvent
public void onLivingDeathEvent(LivingDeathEvent event)
{
	Entity e = event.entity;
	double rand = Math.random();
	if(e instanceof EntitySkeleton)
	{

		System.out.println("a skele iz ded!!!");
		if(rand < 1D)
		{
			e.dropItem(Items.skull, 1);
		}
	}
}

 

Skeletons do drop skulls, however sometimes the skulls seem to be "ghosts" -- you cannot pick them up. also, hoppers cannot pick them up. Am I doing something wrong???

Here's the fix:

 

use a LivingDropsEvent, LivingDeathEvent is called both by the client and the server. The client item is a ghost and cannot be picked up. the end
