hello,Im trying to make a bullet fly from the center of the Car in the
current vector of the car and proceed.like the missiles in twisted
metal.I have some code but it doesnt seem to work.All it displays is the
bullet tmd around the car and wherever the car moves the bullet rotates
around the car.

code Sample:

void Shoot(PlayerStructType2 *theBullet,
                 unsigned long *lModelAddress)
         {
         DrawPlayer(theBullet,&othWorld[currentBuffer]);  
         lModelAddress++;
         GsMapModelingData((unsigned long *)lModelAddress);
         GsInitCoordinate2(WORLD, &theBullet->gsObjectCoord);
         lModelAddress++;  lModelAddress++;
        GsLinkObject4((unsigned
long*)lModelAddress,&theBullet->gsObjectHandler,0);
        theBullet->gsObjectHandler.coord2 = &theBullet->gsObjectCoord;
        
        theBullet->rotation.vx = theCar.gsObjectCoord.coord.t[0];
        theBullet->rotation.vy = theCar.gsObjectCoord.coord.t[1];   
        theBullet->rotation.vz = theCar.gsObjectCoord.coord.t[2];   
        theBullet->gsObjectCoord.coord.t[0] = theBullet->rotation.vx;
        theBullet->gsObjectCoord.coord.t[1] = theBullet->rotation.vy;
        theBullet->gsObjectCoord.coord.t[2] = theBullet->rotation.vz; 
       
AdvanceModel(&theBullet->gsObjectCoord,&theBullet->rotation,&theBullet->speed,256);
        
        theBullet->gsObjectCoord.flg = 0;
}
I call this function when the pad is pressed.
