[SOLVED] How does a metadata block drop metadata items?

[SkylordJoel]

It is possible, make sure the block metadata is the same as the item metadata and use damageDropped and idDropped.

--EDIT--

Hi,

I am making a mod where my metadata ore (gem ore) drops metadata items. I've got everything but the dropping set up. Is it even possible?

 

BlockMetaOre

package addedcompat.common;

import java.util.List;
import java.util.Random;

import cpw.mods.fml.relauncher.Side;
import cpw.mods.fml.relauncher.SideOnly;
import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.client.renderer.texture.IconRegister;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.item.ItemStack;
import net.minecraft.util.Icon;

public class BlockMetaOre extends Block {

public BlockMetaOre(int id, Material material) {
	super(id, material.rock);
	setCreativeTab(AddedCompat.tabAddedCompat);

}

@SideOnly(Side.CLIENT)
private Icon[] icons;

@SideOnly(Side.CLIENT)
public void registerIcons(IconRegister par1IconRegister) {
	//this.blockIcon = par1IconRegister.registerIcon(AddedCompat.modid + ":" + (this.getUnlocalizedName().substring(5)));
	icons = new Icon[2];

	for(int i = 0; i < icons.length; i++) {
		icons[i] = par1IconRegister.registerIcon(AddedCompat.modid + ":" + (this.getUnlocalizedName().substring(5)) + i);
	}
}

@SideOnly(Side.CLIENT)
public Icon getIcon(int par1, int par2) {
	return icons[par2];
}

@SideOnly(Side.CLIENT)
public void getSubBlocks(int par1, CreativeTabs par2CreativeTabs, List par3List) {
	for(int i = 0; i < 2; i++) {
		par3List.add(new ItemStack(par1, 1, i));
	}


}

/*public int damageDropped(int i)
{
switch (i)
{
case 0: return 0;
case 1: return 1;
/*case 2: return 2;
case 3: return 3;
case 4: return 4;
case 5: return 5;
case 6: return 6;
case 7: return 10;
case 8: return 11;
case 9: return 9;
case 10: return 14;
}
return this.blockID;
}
public int idDropped(int par1, Random par2Random, int par3)
{
switch(par1)
{
case 0:
return AddedCompat.metaItemCompat.itemID;
case 1:
return new ItemStack(AddedCompat.metaItemCompat,1,1);
case 10:
return Base.eelEmpty.itemID;
default:
return this.blockID;
}/*


/*public int damageDropped(int i) {
         switch (par1ItemStack.getItemDamage()) 
           {
                  case 0(BLOCK METADATA): return 0(ITEM METADATA);
                  case 1(BLOCK METADATA): return 1(ITEM METADATA);
           }
    }*/

public int damageDropped(int par1) {
	return par1;
	/*if(par1 == 0) {
		return par1;
	}
	switch(par1) {
		case 0: par1 = new ItemStack(AddedCompat.metaItemCompat,1,0);
			break;
		case 1: par1 = new ItemStack(AddedCompat.metaBlockCompat,1,1);
			break;
	}*/

}

}

 

ItemBlockOre

package addedcompat.common;

import net.minecraft.item.ItemBlock;
import net.minecraft.item.ItemStack;

public class ItemBlockMetaOre extends ItemBlock {

public ItemBlockMetaOre(int id) {
	super(id);
	setHasSubtypes(true);
}

public String getUnlocalizedName(ItemStack itemStack) {
	String name = "";
	switch(itemStack.getItemDamage()) {
		case 0: {
			name = "sapphireOre";
			break;
		}
		case 1: {
			name = "rubyOre";
			break;
		}
		default: 
			name = "broken";
		}
		return getUnlocalizedName() + "." + name;
	}

public int getMetadata(int par1) {
	return par1;
}

}

Thanks!

Hi

 

You mean - like harvesting wood gives the corresponding type of wood?

 

Block.damageDropped(int metadata)

 

overridden for BlockWood:

    public int damageDropped(int metaData)

    {

        return metaData;

    }

No, like how dropping redstone ore gives redstone - except with metadata.

[GotoLink]

You need to return an item id for that...

 

public int idDropped(int par1, Random par2Random, int par3)
{
return AddedCompat.metaItemCompat.itemID;
}

[SkylordJoel]

But it's metadata, so how would I take that into account?

Hi

 

If your ItemID is always the same, and only the metadata changes, you can use damageDropped and idDropped as we described.

 

If you want to vary the ItemID as well as the damage value, you could consider overriding Block.getBlockDropped

 

    /**
     * This returns a complete list of items dropped from this block.
     *
     * @param world The current world
     * @param x X Position
     * @param y Y Position
     * @param z Z Position
     * @param metadata Current metadata
     * @param fortune Breakers fortune level
     * @return A ArrayList containing all items this block drops
     */
    public ArrayList<ItemStack> getBlockDropped(World world, int x, int y, int z, int metadata, int fortune)
    {
        ArrayList<ItemStack> ret = new ArrayList<ItemStack>();

        int count = quantityDropped(metadata, fortune, world.rand);
        for(int i = 0; i < count; i++)
        {
            int id = idDropped(metadata, world.rand, fortune);
            if (id > 0)
            {
                ret.add(new ItemStack(id, 1, damageDropped(metadata)));
            }
        }
        return ret;
    }

Thanks TheGreyGhost, it worked.

[TheGreyGhost]
