I have just started on writing a mod that is adding a custom furnace. After following the tutorial twice, the item in the inventory  keeps facing the wrong way. I've been facing this problem for about two days now and it's starting to annoy me greatly.

 

This is my code:

package net.twp.blocks;

import net.minecraft.block.Block;
import net.minecraft.block.BlockContainer;
import net.minecraft.block.material.Material;
import net.minecraft.client.renderer.texture.IIconRegister;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.util.IIcon;
import net.minecraft.util.MathHelper;
import net.minecraft.world.World;
import net.twp.ArkTWP;
import net.twp.registry.BlockRegistry;
import cpw.mods.fml.relauncher.Side;
import cpw.mods.fml.relauncher.SideOnly;

public class BlockAlloyFurnace extends BlockContainer{

private final boolean isActive;
@SideOnly(Side.CLIENT)
private IIcon iconFront;
@SideOnly(Side.CLIENT)
private IIcon iconTop;

public BlockAlloyFurnace(boolean isActive) {
	super(Material.iron);
	this.isActive = isActive;
}

@Override
@SideOnly(Side.CLIENT)
public void registerBlockIcons(IIconRegister iconRegister){
	this.blockIcon = iconRegister.registerIcon(ArkTWP.modID + ":AlloyFurnaceSide");
	this.iconFront = iconRegister.registerIcon(ArkTWP.modID + ":" + (this.isActive ? "AlloyFurnaceActive" : "AlloyFurnaceIdle"));
	this.iconTop = iconRegister.registerIcon(ArkTWP.modID + ":AlloyFurnaceTop"); 
}

@Override
@SideOnly(Side.CLIENT)
public IIcon getIcon(int side, int metadata){
	//return meta == 0 && side == 3 ? this.iconFront : (side == meta ? this.iconFront: this.blockIcon);
	return side == 1 ? this.iconTop : (side == 0 ? this.iconTop : (side != metadata ? this.blockIcon : this.iconFront));
}

public Item getItemDropped(World world, int x, int y, int z){
	return Item.getItemFromBlock(ArkTWP.AlloyFurnaceIdle);
}

@Override
public void onBlockAdded(World world, int x, int y, int z){
	super.onBlockAdded(world, x, y, z);
	this.setDefaultDirection(world, x, y, z);
}

private void setDefaultDirection(World world, int x, int y, int z) {
	if(!world.isRemote){
		Block b1 = world.getBlock(x, y, z - 1);
		Block b2 = world.getBlock(x, y, z + 1);
		Block b3 = world.getBlock(x - 1, y, z);
		Block b4 = world.getBlock(x + 1, y, z);
		byte b0 = 3;
		if(b1.isNormalCube() && !b2.isNormalCube()){
			b0 = 3;
		}
		if(b2.isNormalCube() && !b1.isNormalCube()){
			b0 = 2;
		}
		if(b3.isNormalCube() && !b4.isNormalCube()){
			b0 = 5;
		}
		if(b4.isNormalCube() && !b3.isNormalCube()){
			b0 = 4;
		}

		world.setBlockMetadataWithNotify(x, y, z, b0, 2);
	}
}

@Override
public TileEntity createNewTileEntity(World var1, int var2) {
	return null;
}

@Override
public void onBlockPlacedBy(World world, int x, int y, int z, EntityLivingBase entityPlayer, ItemStack itemStack){
	int l = MathHelper.floor_double((double)(entityPlayer.rotationYaw * 4.0F / 360.0F) + 0.5D) & 3;

	if(l == 0){
		world.setBlockMetadataWithNotify(x, y, z, 2, 2);
	}
	if(l == 1){
		world.setBlockMetadataWithNotify(x, y, z, 5, 2);
	}
	if(l == 2){
		world.setBlockMetadataWithNotify(x, y, z, 3, 2);
	}
	if(l == 3){
		world.setBlockMetadataWithNotify(x, y, z, 4, 2);
	}
	if(itemStack.hasDisplayName()){
		//TODO ((TileEntityAlloyFurnace)world.getTileEntity(x, y, z).setGuiDisplayName(itemstack.getDisplyName());
                        //I have yet to get to this, this problem has been taking most of my time.
	}
}

}

Bump

You need to make sure that if the variable "side" is equivalent to 3 you have to give back the front texture. This applies only when the block is in the inventory. In other cases, you must use the metadata. I can not tell if it is fully correct. I have just getting started.

I essentially copy/pasted the line from the furnace file from Minecraft to get the that line, and that's what the guy that's doing the tutorial did as well, yet I keep getting this error. And setting the side 3 equal to the front will net me a furnace with two faces.

Has no one ever had this problem besides me? I've searched all over and haven't found anything.
