[hlcoders] tr.plane.normal only returns y value of normal?

[Kenrick Rilee]

I added a secondary attack to the 357 (just for testing) in which I find the
wall in front of the gun and find the normal vector of that wall. However,
when I read out the x,y, and z values of this vector, it seems only the y
vector changes. here's the relevant code:

    Vector vecSrc = pPlayer->Weapon_ShootPosition();
    Vector vecAiming    = pPlayer->GetAutoaimVector( AUTOAIM_5DEGREES );
    trace_t tr;
    UTIL_TraceLine(vecSrc,vecSrc + vecAiming *
MAX_TRACE_LENGTH,MASK_SOLID,this,COLLISION_GROUP_NONE,&tr);

    if(tr.DidHitWorld())
    {
        Vector vUp = tr.plane.normal;

        Msg("%d,%d,%d\n",vUp.x,vUp.y,vUp.z); // only vUp.y changes
    }


Thanks,
Kenrick Rilee

(btw i hope i don't sound too much like a noob :/)
