Small C# error

I am converting a C# to JS script and I got to a point where I am not sure how to continue;

Vector3 localVelocity = transform.InverseTransformDirection(rigidbody.velocity);

gives me this error:

';' expected. Insert a semicolon at the end.

It must be dead simple but I am stuck :slight_smile:

var instead of Vector3 or var localVelocity : Vector3
