Disabling damage if player uses wrong weapon

Hey, I need to know how can I disable damage to the player if the attacker is using wrong weapon, for example if he needs to bash but he shoots at the victim.
I think functions like isFiring() and isLookingAt() would help me do it, but whats the function to disable damage to the player that is being looked at, everything else I know already :P
Thanks in advance.

if(sMeansofDeath != "MOD_MELEE")
iDamage=0;

please use return; instead of idamage = 0;, as idamage gets checked further along the way.

You want to make an bashmode?

Code:

---

if(getCvar("scr_bash") == "1" && sMeansOfDeath != "MOD_MELEE")
        return;

---

Also if u just want to prevent damage on some weapons as example:

Code:

---

if(sWeapon == "mp44_mp")
      return;

---

Also if you want to do like headshot does x2 or x3 damage, you can do the same

Code:

---

if(sHitLoc == "head" && sWeapon == "thompson_mp")
      iDamage = iDamage * 3;

---

There are much ways how you can play with the damage thread, same way works if u want to prevent suicide with bazooka or grenades. Just test it out :)

I have a bashmode already made, but atm it just removes ammo so I want to improve it to prevent bugs.
Thanks for help guys :)
