Управляет тем, какая степень свободы допустима при симуляции данного Rigidbody.
By default this is set to RigidbodyConstraints.None, allowing rotation and movement along all axes.
In some cases, you may want to constrain a Rigidbody to only move or rotate along some axes, for
example when developing 2D games. You can use the bitwise OR operator to combine multiple
constraints.
Note that position constraints are applied in World space, and rotation constraints are applied in Local space.
