Melee Problem

I'm trying to implement a simple melee resource that SOUNDED like it would work very simply and do exactly what I want. It's from an old post: http://www.garagegames.com/community/forums/viewthread/27228

In which, Manoel Neto wrote some code which I'm not sure works:


He said -

Well, if it's that simple, you don't even need code changes to spank some bots, or other players.

Bind this function to a key:


function attack(%val)
{
$mvTriggerCount3 = %val;
}


Now define this function in your player class namespace. In the starter.fps mod, this would be Armor. Note that the function already exists in player.cs in the starter.fps mod.



function Armor::onTrigger(%this, %obj, %triggerNum, %val)
{
%attackRadius = 1.5;
%minDot = 0.65;
%damage = 1;

if (%triggerNum == 3 && %val) {
InitContainerRadiusSearch(%obj.getPosition(), %radius, $TypeMasks::PlayerObjectType);
while(( %targetObject = ContainerSearchNext() ) > 0 )
{
//Skip itself
if (%targetObject == %obj)
continue;

//Calculate the dot product
%direction = VectorSub(%targetObject.getWorldBoxCenter(), %obj.getPosition());
%direction = VectorNormalize(%direction);
%dot = VectorDot(%direction, %obj.getForwardVector());

//Skip object if it's angle is too great
if (%dot < %minDot)
continue;

//Apply damage & impulse
%targetObject.applyDamage(%damage);
%targetObject.applyImpulse(%targetObject.getPosition(), %direction);
}
}
}

I can't get this code to work for the life of me! I have the key bound, I've added echos to make sure the function is getting called and everything, but I can't get any sort of reaction from a stationary bot. The impulse doesn't seem to be working at all.

All I want ot do is be able to press a button and send bots flying from melee range without doing the "fire a projectile" fix. Am I wrong about this resource? It seems like it picks a radius and attacks all within the arc "minDot".
