Undo freeze rotation rigidbody2d

Unity Engine
1

I’ve searched around but can’t find the right answer.

I have a gameobject with a rigidbody2D on it. I’ve checked the Freeze Rotation Z so it can’t rotate.
If the player dies I want the freeze rotation not to work anymore.
In another post I found something about using RigidbodyConstraints2D but that doesn’t seem to work.

public RigidbodyConstraints2D playerConstraints;
public int playerLives = 3;

void Update()
{
  if (playerLives == 0)
  {
  playerConstraints = RigidbodyConstraints2D.None;
  }

If I make playerLives 0 the Freeze Rotation Z box stays checked.

How can I uncheck the Freeze Rotation Z box with C#?

Try this. Haven’t use it.

freezeRotation sounds right (never used it that I recall).

However, with regard to your original post, you never assign it back to the rigidbody, which is why it wasn’t appearing to work. :slight_smile:

Already tried this but can’t make it work. I’ve used the bool but nothing happens.

I think methos5k is right, you may not be applying it to the rigidbody in code.

It’s working for me. :slight_smile:

Rigidbody2D rb;

void Awake()
{
   rb = GetComponent<Rigidbody2D>();
}
void Update()
{
   if (Input.GetMouseButtonDown(0))
      rb.freezeRotation = !rb.freezeRotation;

   if (Input.GetMouseButtonDown(1))
   {
      RigidbodyConstraints2D rbc = rb.constraints;
      if (rbc == RigidbodyConstraints2D.FreezePosition)
         rbc = RigidbodyConstraints2D.FreezeRotation | RigidbodyConstraints2D.FreezePositionY;
      else rbc = RigidbodyConstraints2D.FreezePosition;
      rb.constraints = rbc;
   }
}

Added a second example to show some constraints comparisons/assignment. :wink:
(Edited into the post above*).

Yes, I forgot to assign it. It’s hard to be a noob but lucky for me you guys are here.
Thanks for helping out. Works great right now.
