Hello guys. So I have a block that spawns in an item everytime you touch it with a fuel item such as coal. Also, since coal has 8 operations in a furnace I have number which I set and I set it to 8. That will spawn 8 of those items. This worked in 1.6.4. But now when Im updating its not working. Heres my code.

public boolean onBlockActivated(World world, int x, int y, int z, EntityPlayer player, int i, float f, float g, float t){
        System.out.println("Activiated");
        System.out.println(player.getHeldItem());
	if(player.getHeldItem() == null){num = 0;}   
        else if(player.getHeldItem() == new ItemStack(Items.coal)){num = 8;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.log)){num = 2;player.getHeldItem().stackSize--;} 
        else if(player.getHeldItem() == new ItemStack(Blocks.log2)){num = 2;player.getHeldItem().stackSize--;} 
        else if(player.getHeldItem() == new ItemStack(Blocks.planks)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.wooden_slab)){num = 1;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.sapling)){num = 1;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Items.wooden_axe)){num = 1;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Items.wooden_pickaxe)){num = 1;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Items.wooden_hoe)){num = 1;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Items.wooden_shovel)){num = 1;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Items.wooden_sword)){num = 1;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.wooden_pressure_plate)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Items.stick)){num = 1;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.fence)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.fence_gate)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.oak_stairs)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.spruce_stairs)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.birch_stairs)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.jungle_stairs)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.jungle_stairs)){ num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.acacia_stairs)){num = 2; player.getHeldItem().stackSize--;}  
        else if(player.getHeldItem() == new ItemStack(Blocks.dark_oak_stairs)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.trapdoor)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.crafting_table)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.bookshelf)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.chest)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.trapped_chest)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.daylight_detector)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.jukebox)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.noteblock)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.brown_mushroom_block)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.red_mushroom_block)){num = 2;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Items.blaze_rod)){num = 8;player.getHeldItem().stackSize--;}
        else if(player.getHeldItem() == new ItemStack(Blocks.coal_block)){num = 80;player.getHeldItem().stackSize--;System.out.println(num);}
        else if(player.getHeldItem() == new ItemStack(Items.lava_bucket)){num = 100;player.getHeldItem().stackSize--;}
        if(world.isRemote && num!=0)
        {
            System.out.println(num);

            EntityItem ei = new EntityItem(world, x, y + 1, z, new ItemStack(RottenFleshMod.cookedZombieFlesh, num));
            world.spawnEntityInWorld(ei);
            System.out.println("DID IT");
            
            num = 0;
            
        }
        return true;

 

you can use itemstack.isItemEqual(Items.coal)

Is it,

else if(player.getHeldItem().getUnlocalizedName().substring(5).equals(Items.coal.getUnlocalizedName().substring(5))){num = 8;player.getHeldItem().stackSize--;}

It seems to work.
