When I try to place down my block with metadata, it always places down the first metadata.

 

My BlockLeaf class:

public class CanadiaLeaf extends BlockLeaves{

public static final String[][] leafTypes = new String[][] {{"LeafMaple", "LeafRedCedar"}, {"leafMapleOpaque", "leafRedCedarOpaque"}};
public static final String[] leaves = new String[] {"Maple", "RedCedar"};

protected void func_150124_c(World world, int x, int y, int z, int side, int meta)
    {
        if (meta == 1)
        {
            this.dropBlockAsItem(world, x, y, z, new ItemStack(Canadia.maplesap, 1, 0));
        }
    }

    /**
     * Determines the damage on the item the block drops. Used in cloth and wood.
     */

public Item getItemDropped(int p_149650_1_, Random p_149650_2_, int p_149650_3_)
    {
        return Item.getItemFromBlock(Canadia.blockSapling);
    }


    public int damageDropped(int i)
    {
        return super.damageDropped(i) + 0;
    }

    /**
     * Get the block's damage value (for use with pick block).
     */
    public int getDamageValue(World world, int x, int y, int z)
    {
        return world.getBlockMetadata(x, y, z);
    }

    /**
     * returns a list of blocks with the same ID, but different meta (eg: wood returns 4 blocks)
     */
    @SideOnly(Side.CLIENT)
    public void getSubBlocks(Item item, CreativeTabs tab, List list)
    {
    	for(int i = 0; i < leaves.length; i++){
		list.add(new ItemStack(item, 1, i));
	}
    }

    @SideOnly(Side.CLIENT)
    public void registerBlockIcons(IIconRegister iconregister)
    {
        for (int i = 0; i < leafTypes.length; ++i)
        {
            this.field_150129_M[i] = new IIcon[leafTypes[i].length];

            for (int j = 0; j < leafTypes[i].length; ++j)
            {
                this.field_150129_M[i][j] = iconregister.registerIcon(Canadia.MODID + ":" + this.getUnlocalizedName().substring(5) + leafTypes[i][j]);
            }
        }
    }

@Override
public IIcon getIcon(int side, int meta) {
	return (meta & 3) == 1 ? this.field_150129_M[this.field_150127_b][1] : this.field_150129_M[this.field_150127_b][0];
}

@Override
public String[] func_150125_e() {
	return leaves;
}

@Override
public boolean renderAsNormalBlock() {
	return false;
}

@Override
public boolean isOpaqueCube(){
	return false;

}

@Override
public boolean shouldSideBeRendered(IBlockAccess blockaccess, int x, int y, int z, int side){
	return true;
}
}

 

 

And my ItemBlockLeaf class:

 

public class ItemLeafBlocks extends ItemBlock {

public static final String[] leaves = new String[] {"Maple", "RedCedar"};

public ItemLeafBlocks(Block block) {
	super(block);
	this.setHasSubtypes(true);
}

public String getUnlocalizedName(ItemStack itemstack){
	int i = itemstack.getItemDamage();
	if (i < 0 || i >= leaves.length){
		i = 0;
	}

	return super.getUnlocalizedName() + "." + leaves[i];
}

public int getMetaData (int meta){
	return meta;
}
}

 

Thanks for your help!

You need to extend ItemBlockWithMetadata for your block's item, not ItemBlock; also, the default implementation for Block#damageDropped simply returns zero - calling super for that method is pointless; instead, you should just return i directly, as that is the metadata.

Thank you! that helped a lot!
