I'm having the utmost trouble in converting this small piece of engine code to pawn for CS 1.6 that I found when Arkshine posted it.

It's how the engine detects backstabbing from the knife.

Any help on this would be great as I have no knowledge of how to work with C++. (I presume its C++)

PHP Code:

float damage = 65.0;

if ( pEntity && pEntity->IsPlayer() )
{
    Vector2D vec2LOS;
    Vector   vecForward = gpGlobals->v_forward;

    UTIL_MakeVectors( m_pPlayer->pev->angles );

    vec2LOS = vecForward.Make2D();
    vec2LOS = vec2LOS.Normalize();

    if ( DotProduct( vec2LOS, gpGlobals->v_forward.Make2D() ) > 0.8 )
    {
        damage *= 3.0;
    }
}

Can you explain a bit more, about its function ?

It detects whether a knife stab was in the back of the enemy, and if it is, the damage is multiplied by 3.

You could theoretically check on Ham_TraceAttack hitbox, if it wasn't arm or leg or something, it could be a backstab.

Then check if the victim can see attacker, that possibly could do the trick, but it may not be completely accurate.

There for sure is a better way using xs and things like that, but I'm unfamiliar with them so this is the only advice I can give you.

Seems like there is something missing in the code, pEntity should be used somewhere in that block.

To convert, you could try to set pEntity pev_fov to 0.8, send is_in_viewcone and reset pev_fov but i'm not sure it would work.
If you use orpheu, then it should work, same tip but using offset m_flFieldOfView and function CBaseMonster::FInViewCone.
If you really want to convert, then have a look at fm_is_in_viewcone stock in fakemeta_util.inc
