Calling for Entity inventory by hitEntity()

Hello,

I am rewriting my mod from ML to FML and I can't get this stuff working.

What we have is MyModWeapon which extends ItemSword and MyModWeaponBlunt which extends MyModWeapon.

ItemSword>>MyModWeapon>>MyModWeaponBlunt

Now what Blunt weapon should do is to hitEntity() get attacked entity inventory and check what type of armour it is wearing (platemail protects from blunt damage, but weak armours will be crushed and ignored/lowered).

@Override
public boolean hitEntity(ItemStack ItemStack, EntityLivingBase ent, EntityLivingBase ent2)
	{
	ItemStack.damageItem(1, ent2);
	if(ent instanceof EntityPlayer)
	{
		EntityPlayer attackedPlayer = (EntityPlayer)ent;
		ItemStack helmet = attackedPlayer.getCurrentItemOrArmor(4);
		ItemStack chest = attackedPlayer.getCurrentItemOrArmor(3);
		ItemStack legs = attackedPlayer.getCurrentItemOrArmor(2);
		ItemStack boots = attackedPlayer.getCurrentItemOrArmor(1);
		//if armour == light give piercing damage else give normal values
	}
}

Now the problem is I have no idea what am I doing here so I need help.

Will this work?

Which one of these calls for what? Not sure if I am using them properly...

Mine: EntityLivingBase ent, EntityLivingBase ent2

Vanilia: EntityLivingBase par2EntityLivingBase, EntityLivingBase par3EntityLivingBase
