The class:

 

 

package com.manslaughter777.moondimension.event;

import com.manslaughter777.moondimension.Main;
import com.manslaughter777.moondimension.entity.EntitySpaceman;
import com.manslaughter777.moondimension.inventory.InventoryTool;
import com.manslaughter777.moondimension.items.ItemMoonPickaxe;
import com.manslaughter777.moondimension.items.ItemToolUpgrade;

import net.minecraft.block.Block;
import net.minecraft.block.BlockOre;
import net.minecraft.block.BlockSand;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.init.Blocks;
import net.minecraft.init.Items;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;
import net.minecraftforge.event.world.BlockEvent;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;

public class HarvestDropsEvent {

@SubscribeEvent
public void onBlockBreak(BlockEvent.HarvestDropsEvent event) {
	EntityPlayer player = event.harvester;
	World world = event.world;
	Block block = event.block;
	int x = event.x;
	int y = event.y;
	int z = event.z;	

	//InventoryTool inv = new InventoryTool(player.getHeldItem());


	if(player.getHeldItem() != null) { //this is line 34, where the crash report leads to
		if(player.getHeldItem().getItem() instanceof ItemMoonPickaxe) { //only pickaxes
			if(new InventoryTool(player.getHeldItem()).upgrade[itemToolUpgrade.oreHarvesterId] == true) {

				if(block instanceof BlockSand) {
					event.drops.add(new ItemStack(Blocks.anvil));
					event.drops.remove(new ItemStack(Blocks.sand));
				}
			}
		}
	}

}

}

    Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

     

    1.12 -> 1.13 primer by williewillus.

     

    1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.
