Freeze Z Rotation programmatically - Unity 2D

In the Unity inspector (v5+), you have a "Freeze Z" rotation, any idea which is the equivalent in code? The idea is to enable/disable Z rotation of a 2D object due a certain condition by C# code.

To put this as an answer for 2D, use the following:

Rigidbody2D body2d;

void Awake() {

    body2d = GetComponent<Rigidbody2D> ();

}

void Update () {

    // on this line, calculate condition for freezing rotation

    if (condition) {

        body2d.constraints = RigidbodyConstraints2D.FreezeRotation;

    } else {

        body2d.constraints = RigidbodyConstraints2D.None;

    }

}

You want to set the Rigidbody.constraints to a RigidbodyConstraint:

transform.rigidbody.constraints = RigidbodyConstraints.FreezePositionZ;

The RigidbodyConstraint constants can be combined with the | operator:

rigidbody.constraints = RigidbodyConstraints.FreezeRotationX | RigidbodyConstraints.FreezeRotationY;
