I've been looking for a way to drop items from a block for my mod, I want it to drop 5-6 items. I've been looking in the tutorials section and googled it but found nothing recent for 1.6. Can anyone help?

You can use idDroped, damageDroped, quantityDroped in Block, if it is at block break you want it to happen.

 

I've tried using idDropped and quantityDropped, and it crashed the game when I break the block

at oBlox.block.BlockRedTrintiumOre.idDropped(BlockRedTrintiumOre.java:20)

 

Lets see, line 20...

 

package oBlox.block;

import java.util.Random;

import oBlox.item.ModItems;
import net.minecraft.block.Block;
import net.minecraft.block.material.Material;

public class BlockRedTrintiumOre extends Block {
        public BlockRedTrintiumOre(int id) {
                super(id, Material.rock);
                this.setUnlocalizedName("Red Trintium Ore");
        }
}

 

Your code only goes up to line 17.  And does not contain an idDropped method.

I removed the idDropped method when I updated the github, just relized that, sorry. Heres the code for the block.

 

 

package oBlox.block;

import oBlox.lib.ItemIds;
import net.minecraft.block.Block;
import net.minecraft.block.material.Material;

public class BlockRedTrintiumOre extends Block {

public BlockRedTrintiumOre(int id) {
	super(id, Material.rock);
	this.idDropped(ItemIds.REDTCRYSTAL_DEFAULT, null, id);
	this.setUnlocalizedName("Red Trintium Ore");
}



}

 

EDIT- this is what I have at the moment, I'm going to debug right now and most likely post a crash report in a few minutes

You need to override that method, not call it.

 

So in you block class add:

 

public int quantityDropped(Random par1Random)
    {
        return 5;
    }

If you want to drop 5 items. That method will be called by others.

This is what I have now after the overriding suggestion, does it look good?

 

package oBlox.block;

import java.util.Random;

import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import oBlox.item.ModItems;

public class BlockRedTrintiumOre extends Block {

public BlockRedTrintiumOre(int id) {
	super(id, Material.rock);
	this.setUnlocalizedName("Red Trintium Ore");
}


@Override
public int quantityDropped(Random par1Random)
    {
        return 6;
    }


@Override
public int idDropped(int par1, Random par2Random, int par3)
    {
        return ModItems.redTCrystal.itemID;
    }
}

Do this:

 

	@Override
public int idDropped(int par1, Random par2Random, int par3)
    {
        System.out.println("About to crash, ModItems: " + ModItems);
        System.out.println("About to crash, redTCrystal: " + ModItems.redTCrystal);
        System.out.println("About to crash, itemID: " + ModItems.redTCrystal.itemID);
        return ModItems.redTCrystal.itemID;
    }

 

Won't fix your problem, but it'll tell you which object is null.

Right.  Cause you can't do that.

Sometimes I type stuff out and it doesn't work, just delete that line.  I'm pretty sure we can be confident that the class exists.

Ok this doesnt crash the game when I break the block

package oBlox.block;

import java.util.Random;

import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import oBlox.lib.ItemIds;

public class BlockRedTrintiumOre extends Block {

public BlockRedTrintiumOre(int id) {
	super(id, Material.rock);
	this.setHardness(2);
	this.setUnlocalizedName("Red Trintium Ore");
}


@Override
public int quantityDropped(Random par1Random)
    {
        return 6;
    }


@Override
public int idDropped(int par1, Random par2Random, int par3)
    {
        return ItemIds.REDTCRYSTAL_DEFAULT;
    }
}

 

But i don't get the items and the console prints this ""Attempted to add a EntityItem to the world with a invalid item: ID 2500 at (342.41,  34.68, 42.32), this is most likely a config issue between you and the server. Please double check your configs"

And this ID you can get like how you did earlier: "ModItems.redTCrystal.itemID". The problem then was that redTCrystal was null. So find out why, because that's not normal. Probably you haven't initialized your item (redTCrystal = new Item....).

I'd like to thank everyone that posted, and Id like to say that I got it working thanks to everyone's help :)

 

The code will be updated on github in a while after I add the rest of the items and oreGen, and ill possibly make textures first too
