iTween 2D Path rotation

Questions & Answers
1

I am trying to use iTween to follow a looping path I created and have my sprite orient to the path on the z-axis so it rotates as it follows the path. I am using 2D Toolkit sprites.

The problem is that it doesn’t seem to be working. And if I don’t restrict the Z-axis, the sprite becomes invisible because of x/y rotation happening. Not sure what I am doing wrong.

Relevant Code Snippets:

    if (Input.GetKeyUp(KeyCode.L) && !bCharFollowingPath)
    {
        bCharFollowingPath = true;
        ht = new Hashtable();
        ht.Add("path", iTweenPath.GetPath("Loop1"));
        ht.Add("time", 4f);
        //ht.Add("looktime", 0.6f);
        ht.Add("lookahead", 0.1f);
        ht.Add("orienttopath", true);
        ht.Add("axis", "z");
        ht.Add("easetype", iTween.EaseType.linear);
        ht.Add("oncomplete", "Path_OnComplete");
        ht.Add("oncompletetarget", this.gameObject);

        iTween.MoveTo(sprChar.gameObject, ht);	
    }
}

void Path_OnComplete()
{
    Debug.Log("Done");

    bCharFollowingPath = false;
    sprChar.transform.position = new Vector3(150, -316, -5);
    sprChar.transform.eulerAngles = new Vector3(0, 0, 0);
}

z-restricted:

not z-restricted:

It does appear by looking at the wireframe on the not-z restricted, that it is following the path and rotating but not in a way that is useful =)

Any help greatly appreciated.

Just put, your sprite in empty game object and make it z orientated.
