Most effective way to remove vanilla mob drops, without editing anything?

Frontsalat · July 27, 2013

The title basically says it. I'm aware of ways where you'd just replace the vanilla mob with a custom one, and then let this custom mob drop the things you want it to drop. But 1. this is ensured to create bugs with mods like Mo Creatures and 2. creates miriads of unnecessary files filled with walls of code. Isn't there something more elegant like this for blocks?

Block.blocksList[block.oreCoal.blockID] = Block.blocksList[MetallurgyRealismModBase.BlockSlate.blockID];

Something like, for example:

Item.itemsList[item.leather.itemID] = Item.itemsList[MetallurgyRealismModBase.MaterialFur.itemID];

Look, if you know something, don't give me tension torture. If you'd happen to know something just speak it out loud, without acting all superior. I wouldn't come here and ask if I haven't already tried my butt off. Obviously I'm already using event code:

package MetallurgyRealism;

import net.minecraft.entity.item.EntityItem;
import net.minecraft.entity.passive.EntityChicken;
import net.minecraft.entity.passive.EntityCow;
import net.minecraft.entity.passive.EntityPig;
import net.minecraft.entity.passive.EntitySheep;
import net.minecraft.entity.passive.EntityWolf;
import net.minecraft.item.Item;
import net.minecraftforge.event.ForgeSubscribe;
import net.minecraftforge.event.entity.living.LivingDropsEvent;

public class MetallurgyRealismLivingDrops {
public static double rand;

@ForgeSubscribe
public void onEntityDrop(LivingDropsEvent event) {
	if (event.source.getDamageType().equals("player")) {
		rand = Math.random();
		System.out.println("Killed something.");
		if (event.entityLiving instanceof EntityCow || event.entityLiving instanceof EntitySheep || event.entityLiving instanceof EntityChicken || event.entityLiving instanceof EntityPig || event.entityLiving instanceof EntityWolf) {
			System.out.println("Killed a sheep.");
			if (rand < 0.1D) {
				event.entityLiving.dropItem(Item.bone.itemID, 2);
			}
		}
	}
}
}

But adding new drops isn't the same as removing the vanilla ones.

GotoLink · July 27, 2013

Cancel the event.

i tend to be this way when i'm sleepy. so... get over it. at least i gave the answer (but apparently not enough)

I wouldn't come here and ask if I haven't already tried my butt off. Obviously I'm already using event code:

no, you never once mentioned you were using the events already. so no, not "obviously".

But adding new drops isn't the same as removing the vanilla ones.

obviously.

anyway, to answer your question completely and properly:

you can do what gotolink said, but that would stop all the entity's drops from spawning. if you want it that way, then go ahead. if you want to remove just a specific item, iterate through the list of drops and check if it's the item you want to replace, then replace it, if it is.

Frontsalat · July 27, 2013

Cancel the event.

This would have an effect on the new items added or on any single item to be spawned by dead entitys, but does absolutely nothing to singled out vanilla drops. Except you want me to edit base files...

The iteration did not seem to work on items dropped by mobs. I got it working on blocks, but there's no equivalent code...or at least I found none. Also tried to modifie this code, to no avail:

    		Iterator<IRecipe> iterator = CraftingManager.getInstance().getRecipeList().iterator();

    			while (iterator.hasNext()){
    				IRecipe recipe = iterator.next();
    				if (recipe == null)
    				continue;
    					ItemStack output = recipe.getRecipeOutput();
    				if (output != null && output.getItem() != null && removeSet.contains(output.getItem()))
    					iterator.remove();}

erm.. cancelling an event doesn't require base class edits. and i just tried what i said earlier and it works. you're just not doing it right. also, that code you tried to modify is for recipes so i have no idea what you tried to do with it. i'd post code, but you clearly don't know what you're doing, so you're going to either have to try harder and figure it out yourself (which i recommend so you won't have to rely on the forums) or wait til someone's nice enough to post code. also, everything you need is already in your "public void onEntityDrop(LivingDropsEvent event)" method, so it shouldn't be too hard to figure out. you just need to change some stuff in there (and i already said what to do earlier). goodluck, ima head to bed

GotoLink · July 27, 2013

Wait, so you want to remove mob drop that are craftable ?

Do they even exist ?

I'd say I have to go with something like...

event.entityLiving.removeItem(Item.leather.itemID)

...but it didn't work

So I was right when thinking you're the little smarty by reading all the miriads of your posts on this forums, telling people to learn something, instead of just helping them. Look, it gains you nothing in life to know so much about Java code. But it gains you a lot of envy by acting like a dick. And obviously I can't know as much about Java as you do, because clearly I have a life. It's not lag of skills or commitment, it's simply a lag of time.

Modding communitys are supposed to share and help each other, at least that's what we're doing over at Skyrim Community...seems like attitude over here is far more reserved and superior. Feel pleased about your skills, because that's probably all you got.

Exceptionally I want to remove leather drops from cows and make them drop fur instead, so I'm capable of processing it.

hydroflame · July 27, 2013

living drop event has a ArrayList, just remove the item from that list...

GotoLink · July 27, 2013

ItemStack stack;
Iterator drop = event.drops.iterator();
while(drop.hasNext())
{
stack = ((EntityItem)drop.next()).getEntityItem();
if(stack!=null && stack.getItem().itemID == Item.leather.itemID)
{
iterator.remove();
event.drops.add(new EntityItem(world,x,y,z, new ItemStack(furID));
} 
}

soooo close... try looking up arraylists if you don't know how to use them.

So I was right when thinking you're the little smarty by reading all the miriads of your posts on this forums, telling people to learn something, instead of just helping them.

and which posts did you read exactly? because as far as i remember i only answer like a dick when the answer to the question is annoyingly simple and can be figured out with just a bit of research (in your case, it shouldn't even take 10 minutes). or if i know the op to be a dick. but i still give answers which should be enough to help them

who says i know a lot about java? i learn java on my own and as a hobby. and i'm an architecture student (meaning my workload is ridiculous and i spend most of my time working that i barely get any sleep), but even then i still have a life outside of school and coding. and even then i don't need someone to spoon feed code for me to figure something out.

Modding communitys are supposed to share and help each other, at least that's what we're doing over at Skyrim Community...seems like attitude over here is far more reserved and superior. Feel pleased about your skills, because that's probably all you got.

help others by posting code for them to copy and paste without them understanding what it does? that's not helping at all. i post code when i see that the op knows what he's talking about. if he doesn't, i point them in the right direction so he can figure things out. a buttload of posts here are related to copied code that the ops don't understand and don't bother to... which is annoying.

i pointed you to the answer, but if you're looking for code, i'm not posting any for this. think of me as a dick if you want to, but not everyone here is. i was about to say some guy named hydroflame is usually patient enough to help out a lot, so wait for him. but he already replied here and wadaya know? he said basically the same thing i did.. aaaannd gotolink just posted code.

god damn this is a long post

what the even fuck ? i dont even...

So I was right when thinking you're the little smarty by reading all the miriads of your posts on this forums,

theres a search bar top left of this screen and YES even pro/good modders use it .. they dont ask question unless they know no one else asked them before

telling people to learn something, instead of just helping them

telling people to learn java before modding IS helping them, without basic java knowledge you CANNOT do a mod (even the most simple ones)

copy pasting code is NOT learning btw

Look, it gains you nothing in life to know so much about Java code.

i make 75 000 a year (canada) "knowing about java code".

if 75000 a year is nothing can you give me 75000 per year ?

And obviously I can't know as much about Java as you do, because clearly I have a life.

this argument is so invalid im getting cancer from reading it

you will learn stuff in EVERY profession you can think of (dont try a counterargument where working at mcdonald doesnt require learning anything because that would be pathetic). do you think that literally every developper in the world are in front of their computer 24/7 ?!?!?!?!

nope, most of us have a wife and children and we will do stuff in our daily lives

at least that's what we're doing over at Skyrim Community

please, skyrim modding is a freacking joke

Man, the time it took you to write all thoose walls of text could have been used to just post the damn code. Now get of your throne, you don't even remotely listen to what I'm telling you Java-Nerd. If your job is Java Coding then you probably kicked yourself a penalty in all your weirdo arguments, right? Wait, I'll tell myself so you don't need to upset yourself...GO LEARN JAVA!!! I'M TALKNG TO ME, DO ME HEARD ME??? GO LEARN JAVA!!!

Also, why do I slightly get the feeling no one every achieved that? There should have been a tutorial around already.

At least GoToLink has mercy, but unfortunately I'm obviously to dumb to get further then this, and it still doesn't work:

It is not that people aren't helping. It is that noone can help you if you don't ask the correct question.

In your case, from the very beginning it should have been something like:

I want to remove leather drops from cows and make them drop fur instead.

I began working with LivingDropsEvent, but had no luck, here is my code.
Illustrative code here.

Edit: Man, what are you doing with this onEntityDrop1 method ?

Just place the code into a

if(event.entityLiving instanceof EntityCow)
{
//code here
}

in your first method

Ohh, so you're saying I was to dumb to organize my imports. Well then thank you very much for pointing out my complete lag of understanding Java AND Eclipse. I'll do instantly what you tought me...*hastes pressing ctrl+shift and o (not the zero but the o, like oooohhhh) and anxiously licking his lips for expected success*.

Oh crap, it didn't work...

I'm just curious, if there is any difference in Iterator (which you want to import) and iterator (which is a container reference)?

Your import is good.

"Java-Nerd"? real mature. i suggest you listen to yourself and go learn basic java. i mean f*ck, i already told you how to do it, hydroflame confirmed it, and gotolink basically did it for you. and you still complain?? are you that much of a baby that can't be bothered to figure out the rest yourself? you need absolutely everything done for you? get over yourself

Frontsalat · July 28, 2013

how do you know about "organising imports" but not what an iterator is ?? this is contradictory ish

Probably because I'm not a simple copy paster, yet not a skilled coder. I'm somewhere in between, loosely base my understanding of code on trial and fail...

I said I'm in lag of time to learn every single portion of Java code. I do know from Phython code that a iterator is something that's used to traverse between objects or containers. At least that's what the Java and the Phython Tutorial said.

So, what does Eclipse say of this underlined error ?

All possible fixes, but drop.remove was none of them. I thought since the "Iterator iterator" was nowhere defined, I had to define it. However, changing it to drop.remove fires out this error log...
