Add a mob drop to existing mob without editing base classes

[WeeziMonkey]

Hi, im making a mod, as probably most people here... For that i want to add a mob drop to monsters. For now lets say its just a gem.

 

I will not show the class because i have yet to make, but lets say its a totally useless item for now, only exisiting and texture.

 

The problem im having is that i want it to be dropped by monsters that die. If possibile a small chance. But i heared its a bad idea to edit base classes. So how can i do this?

use the LivingDropsEvent

use the LivingDropsEvent

 

And now more detail please? I found the class, and have been trying things for more than half a hour. How do i add that method? And exactly where?

Ive did everything there, but i dont understand how to make sure there is also a chance my gem gets dropped by a dead mob, along with their usual stuff. Can i just, and if so where, do something like "drop = Item.diamond"? (diamond just to test first) My event class:

 

package nomar.extramod;

import java.util.ArrayList;

import net.minecraft.entity.EntityLiving;
import net.minecraft.entity.item.EntityItem;
import net.minecraft.item.Item;
import net.minecraft.util.DamageSource;
import net.minecraftforge.event.ForgeSubscribe;
import net.minecraftforge.event.entity.living.LivingAttackEvent;
import net.minecraftforge.event.entity.living.LivingDropsEvent;
import net.minecraftforge.event.entity.player.PlayerSleepInBedEvent;


public class AddEvents
{

@ForgeSubscribe
public void mobDrops(LivingDropsEvent event)
{

EntityLiving aaEntity = event.entityLiving;
DamageSource aaDamage = event.source;
ArrayList<EntityItem> aaDrops = event.drops; 


if (event.isCancelable())
{
event.setCanceled(true);
}
}
}

 

In my @init:

MinecraftForge.EVENT_BUS.register(new AddEvents());

what doesn't work? the event is working alright. if you want example here it is: https://github.com/mnn/jaffas/blob/master/src/minecraft/monnef/jaffas/food/item/CustomDrop.java#L73, highlighted line is the adding new item to be dropped from currently killed entity.
