well you showed him what a package is and you somehow told it to add velocity to the golf club not the vehicle?
at least you used [tt]
package GolfClub
{
function golfClubProjectile::onHit(%this, %obj, //Other variables, someone fill this in
{
//Vector code goes here, but I'm not good at maffs, someone help here too
parent::onHit(%this, %obj, other variables);
}
};
activatePackage(GolfClub);
