[1.6.4] Consumable Item

Hi,

i had a new Class for consumable Items. And now i would like to get back a empty bottle (glassbottle) if the item was used (like the potions).

I had find at the potion code something like:

if (!par3EntityPlayer.capabilities.isCreativeMode)

        {

            if (par1ItemStack.stackSize <= 0)

            {

                return new ItemStack(Item.glassBottle);

            }

 

            par3EntityPlayer.inventory.addItemStackToInventory(new ItemStack(Item.glassBottle));

        }

but i get several errors if i try to implement this in my class so i need some help or ideas.

public class DrinkBasis extends ItemFood {

private String filename;

public DrinkBasis(int par1, int par2, float par3, boolean par4) {
	super(par1, par2, par3, par4);
}

 public EnumAction getItemUseAction(ItemStack par1ItemStack)
    {
+ Attachments and other options
        return EnumAction.drink;	        
    }	

@SideOnly(Side.CLIENT)
public void registerIcons(IconRegister reg){
	this.itemIcon = reg.registerIcon(filename);
}

public void setIconFile(String name){
	filename = name;
}

}
