Do anyone have any tutorials on how to make a sphere move like a marble. In other words, I know I have to add a rigidbody to my character. However, I cannot move the sphere when I add rigidbody.Addforce to the arrow keys. I need help?
Perhaps… you should be looking for rigidbody.AddRelativeTorque… that will force the ball to turn in one direction or another based off your user input. 
Sorry I am late. Thanks
