I want to check for a blocks meta data but im not sure how. Im useing this within the onHarvestDrops(BlockEvent.HarvestDropsEvent event) forge event.

 

       if (event.block.blockID ==  1398){
    	   //if block meta data == 2 {

	event.drops.clear();
        event.drops.add(new ItemStack(Items.tinfragments, random.nextInt(2) + 1));
        event.dropChance = 1.0F;

world.getBlockMetadata(x,y,z)

How do I fix the error with the X Y Z variable or make it so it knows that the X Y Z are.

 

package hydroblocks.lib;

import java.util.Random;

import hydroblocks.items.Items;
import net.minecraft.block.Block;
import net.minecraft.client.resources.data.MetadataSection;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;
import net.minecraftforge.event.ForgeSubscribe;
import net.minecraftforge.event.world.BlockEvent;
import net.minecraftforge.event.world.BlockEvent.HarvestDropsEvent;


public class EventHooks {
Random random = new Random();


@ForgeSubscribe
public void onHarvestDrops(HarvestDropsEvent event) {
int meta = World.getBlockMetaData(x,y,z);


// cobble sledgehammer
if (event.harvester != null && event.harvester.getHeldItem() != null && event.harvester.getHeldItem().itemID == Items.cobblesledgehammer.itemID) {


if (event.block.blockID == 1398 && meta == 2) {
event.drops.clear();
event.dropChance = 1.0F;
event.drops.add(new ItemStack(Items.copperfragments, random.nextInt(2) + 1));
}
}

Use your IDE's code hinting abilities.

 

event.blockMetadata

BTW, at this line:

if (event.block.blockID == 1398 && meta == 2) {

dont use direct id's, but use it like this:

if (event.block.blockID == your_block.blockID && meta == 2) {

That block ID belongs to forestry, and so far I haven't found an effective way other than using block ID to Idenfity that that block is Copper Ore.

	for (ItemStack stack : OreDictionary.getOres("oreCopper"))
	{
		if (event.block.blockID == stack.itemID) {
			event.drops.clear();
			event.dropChance = 1.0F;
			event.drops.add(new ItemStack(Items.copperfragments, random.nextInt(2) + 1));
			break;
		}
	}

 

Works with any ore registered within the ore dictionary as Copper Ore.

Thank you so much I have been looking in vain for a way to do this.
