Why it dsnt work? (C#) What I need to do with it - if ray from "A" script in contact with collider of object attached to "B" script, then in "A" something doing:

    Vector3 ray = transform.TransformDirection(Vector3.forward); 
    Debug.DrawLine(transform.position, ray, Color.green); 
    pickup = ray.collider.GetComponent<rev_pickup>();  
    if(pickup != null) { do(); }

Error:

error CS1061: Type UnityEngine.Vector3' does not contain a definition forcollider' and no extension method collider' of typeUnityEngine.Vector3' could be found (are you missing a using directive or an assembly reference?)
