RigidbodyConstraints.FreezeRotation

Descripción

Congela la rotación a lo largo de todos los ejes.

//Attach this script to a GameObject with a Rigidbody. Press the up and down keys to move the Rigidbody up and down.
//Press the space key to freeze all rotations, but notice the positions still change.
