Can you unfreeze a rigidbody.constraint position as you can freeze them?

Question

Yes, a simple question from me!

I want to freeze the rigidbody's Y position when the game is paused, as in my script:

if(GameManager.gamePaused == true) { transform.rigidbody.constraints = RigidbodyConstraints.FreezePositionY; }

And of course, when I unpause it I naturally want to unfreeze it. Is there a simple way to do that? I've looked around the various tutorials and Unity's scripting API pages, can't find anything about it.

Thanks!

RigidbodyConstraints are bit masks, thus you can use + or | (bitwise OR) to set several constraints at once. To disable a single constraint, AND rigidbody.constraints with the negated mask (~):

   rigidbody.constraints &= ~RigidbodyConstraints.FreezePositionY;

But if you don't have other constraints active, just set rigidbody.constraints to RigidbodyConstraints.None:

   rigidbody.constraints = RigidbodyConstraints.None;

Another way to do this is to simply save the constraints in Awake or Start before changing them.

 var originalConstraints : RigidbodyConstraints;
 
 function Awake()
 {
      originalConstraints = rigidbody.constraints;
 }
 
 function FreezeConstraints()
 {
      rigidbody.constraints = RigidbodyConstraints.FreezePositionY;
 }
 
 function UnFreezeConstraints()
 {
      rigidbody.constraints = originalConstraints;
 }
