Velocity in Unity 2D How to get velocity of object without rigidbody

Question

By using method transform.translate(Vector3.left * 5f * Time.Deltatime; does this change the velocity of a gameobject with a rigidbody ,because in my case it doesnt work.Is there a way i can move an object so the velocity changes .If not is there any way to measure velocity of an object without having a Rigidbody attached to it. Thanks.

Answer 1

You can measure the velocity vector like this:

Vector3 pos, velocity;

void Awake()
{
    pos = transform.position;
}

void Update()
{
    velocity = (transform.position - pos) / Time.deltaTime;
    pos = transform.position;
}
