Unity: detect if path is clear using Raycast

Currently my code looks like this:

    Vector3 tempPos = transform.position;
    Vector3 checkPos = new Vector3(tempPos.x, tempPos.y, Mathf.Round(tempPos.z + 1));
    if (Input.GetKey(KeyCode.W))
        Vector3 direction = checkPos - transform.position;
        Ray ray = new Ray(transform.position, direction);
        RaycastHit hit;
        if (Physics.Raycast(ray, out hit))
        Debug.DrawRay(transform.position, direction, Color.black, 20, false);

however even when i am right up against an object, I get nothing from my Debug.Log() statement. As a matter of fact, I cannot even call a Debug.DrawRay() statement as it doesn’t show anything either. What on Earth could I be doing wrong? Any help would be appreciated. Thanks in advance!

    Hard to know the problem from a small snippet but you could try:

    Vector3 fwd = tempPos.transform.TransformDirection(Vector3.forward);
    if (Physics.Raycast(raycastObject.transform.position, fwd, out objectHit, 50))
