Ghast tentacles [1.47]

i have added an item that when right clicked pawns a fireball but it only shoots in one direction and the .setMaxDamage doesn't work, here is the code

Main Class;

package ashtonsmod.common;

public class ashtonsmod
{
public static Item Tentacle;

@SidedProxy(clientSide = "ashtonsmod.client.ClientProxyashtonsmod", serverSide = "ashtonsmod.common.CommonProxy")
public static CommonProxy proxy;

proxy.registerServerTickHandler();

proxy.registerRenderers();{
Tentacle = new Tentacle(548).setMaxStackSize(1).setIconIndex(44).setItemName("Tentacle").setMaxDamage(32);
DungeonHooks.addDungeonLoot(new ItemStack(ashtonsmod.Tentacle), 10, 1, 1);
LanguageRegistry.addName(Tentacle,"Lesser Ghast Tentacle");
}
}
}

the tentacle class;

package ashtonsmod.common;

public class Tentacle extends Item{


    public Tentacle(int par1)
    {
        super(par1);
        this.setMaxDamage(32);
    }
    
    public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer)
    {
        if (!par3EntityPlayer.capabilities.isCreativeMode)
        {
            --par1ItemStack.stackSize;
        }

        par2World.playSoundAtEntity(par3EntityPlayer, "random.bow", 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F));

        if (!par2World.isRemote)
        {
            par2World.spawnEntityInWorld(new EntitySmallFireball(par2World, par3EntityPlayer, iconIndex, iconIndex, iconIndex));
        }
        par3EntityPlayer.swingItem();
        return par1ItemStack;
    }
    @Override
  	public String getTextureFile(){
  		return CommonProxy.items_png;   
}

   }

Let e know if you need any more code, such as the serverProxy or client proxy or some such like that.
