I'll Help You With Unity: (Not A Team, A Quick TUT For You)
Rigidbodys are key to make players, physical objects, and colliders.
if you want to freeze it from turning, type a line like this:
public Rigidbody NameOfRigidbody;
void FixedUpdate()
{
NameOfRigidbody.freezeRotation = true;
}
and use joints, transforms and detections to make the most out of your Game : )
