public OnPlayerWeaponShot(playerid, weaponid, hittype, hitid, Float:fX, Float:fY, Float:fZ) {
    if (hittype == BULLET_HIT_TYPE_PLAYER && IsPlayerNPC(hitid)) {
        // BULLET_HIT_TYPE_NPC
    }
}

I really doubt that we need an extra hittype for that
A native type wouldnt make it faster than checking for PLAYER || NPC would slow it down.
