When making 2d game, notices?

Unity Engine
1

In official 2d game tutorial, it based on unity2.6, so it uses ‘configurable joint’ and ZMotion, Angular XMotion, Angular YMotion also be locked.

But I think when unity 3.3 currently, rigidbody component has Constraints and Freeze Position and rotation checking can does above function, configurable joint does not need.

  1. Is this right?

  2. If right, how check the box? Freeze Position X Y Z , Freeze Rotation X Y Z

The rigidbody constraints are available in the inspector (there’s a Constraints foldout at the bottom of the Rigidbody component). If you want to stop the object moving in the Z axis then enable the Z component in Freeze Position. If you want to stop all rotation then freeze all three axes.

Hi~!!

so configurable joint is no more need to be attached to block movement of z-axis. right?
