So I am making a Core mod for all of my future mods and I stumbled upon the problem of making a block that has sides change depending on how you place it (like the furnace). Does anyone know how to do this or have a tutorial with full ability to be customized in any way.

 

Thanks in Advanced!,

first, override onBlockPlacedBy:

    /**
     * Called when the block is placed in the world.
     */
    public void onBlockPlacedBy(World par1World, int par2, int par3, int par4, EntityLivingBase par5EntityLivingBase, ItemStack par6ItemStack)
    {
        int l = MathHelper.floor_double((double)(par5EntityLivingBase.rotationYaw * 4.0F / 360.0F) + 0.5D) & 3;

        if (l == 0)
        {
            par1World.setBlockMetadataWithNotify(par2, par3, par4, 2, 2);
        }

        if (l == 1)
        {
            par1World.setBlockMetadataWithNotify(par2, par3, par4, 5, 2);
        }

        if (l == 2)
        {
            par1World.setBlockMetadataWithNotify(par2, par3, par4, 3, 2);
        }

        if (l == 3)
        {
            par1World.setBlockMetadataWithNotify(par2, par3, par4, 4, 2);
        }

        if (par6ItemStack.hasDisplayName())
        {
            ((TileHeatFurnace)par1World.getBlockTileEntity(par2, par3, par4)).setGuiDisplayName(par6ItemStack.getDisplayName());
        }
    }

 

The metadata is the direction of the furnace. You can see Direction class to see the name of each direction

[embed=425,349]if (par6ItemStack.hasDisplayName())

        {

            ((TileHeatFurnace)par1World.getBlockTileEntity(par2, par3, par4)).setGuiDisplayName(par6ItemStack.getDisplayName());

        }[/embed]

Whats that doing?

It is setting the displayed name in the gui of the tile entity. (This code is from my mod, which contains Heat Furnace.)

If your gui-displayed name is constant, you can simply ignore that.

if (l == 0)
        {
            par1World.setBlockMetadataWithNotify(par2, par3, par4, 2, 2);
        }

        if (l == 1)
        {
            par1World.setBlockMetadataWithNotify(par2, par3, par4, 5, 2);
        }

        if (l == 2)
        {
            par1World.setBlockMetadataWithNotify(par2, par3, par4, 3, 2);
        }

        if (l == 3)
        {
            par1World.setBlockMetadataWithNotify(par2, par3, par4, 4, 2);
        }

        if (par6ItemStack.hasDisplayName())
        {
            ((TileHeatFurnace)par1World.getBlockTileEntity(par2, par3, par4)).setGuiDisplayName(par6ItemStack.getDisplayName());
        }
    }

I assume I can ignore all the return statements if I am making this a base class for all Blocks/Block Containers?

Then, you have to use:

        if (par6ItemStack.hasDisplayName())

        {

            ((TileXX)par1World.getBlockTileEntity(par2, par3, par4)).setGuiDisplayName(par6ItemStack.getDisplayName());

        }

 

when TileXX is the class which has setGuiDisplayName.
