Fix Bouncy Helicopters The War Z

[Tutorial] FIX Bouncy Helicopters
Hey guys! Fixed the helicopters in codex's source.

Replace this function

void obj_Vehicle::HelicopterPhysx()

For mine

void obj_Vehicle::HelicopterPhysx() // controls of helicopter
{
 if (isHelicopter == true)
 {
  const float fTimePassed = r3dGetFrameTime();
  PxTransform pose = vd->vehicle->getRigidDynamicActor()->getGlobalPose();
  r3dVector angles;
  r3dPoint3D position(0,0,0);
  PxVec3 HeliGravity(0,0,0);
  PxVec3 NormGravity(0,9.81,0);

  vd->vehicle->getRigidDynamicActor()->setGlobalPose(pose);
  SetPosition(r3dPoint3D(position.x,pose.p.y,position.z)); //Another test
  r3dPoint3D vel = GetVelocity();
  vel.x *= pose.p.x;
  vel.y *= pose.p.y;
  vel.z *= pose.p.y;
  if(vel.Length() < 0.001f) vel = r3dPoint3D(0, 0, 0);
  SetVelocity(vel);
 }
}

Fixed.
Current bugs: Even when not in the helicopter, it gains altitude. Will be fixing here in a bit.
