Move RectTransform according to Screen

Suppose I have an UI Image in the center of the screen (say (width/2, height/2), but I don't remember now if RectTransform consider (0,0) as the center).

How should I do (for example) to move the image so that its center is (0, height/3) ?

 

RectTransform.anchoredPosition

 

obviously I found that, I wouldn't be asking if I hadn't gone through some searching, I even ran over all the discussion between localPosition vs anchoredPosition usage, but I couldn't move the RectTransform according to the screen (as I asked) correcly

 

Are you simply asking for? :

Code (csharp):

1. GetComponent<RectTransform>().anchoredPosition = new Vector3(0, Screen.height/3);

 

I had tried this before but the RectTransform was moving strangely (I think it didn't move enough although it moved the correct direction vector), do you know any constant that could be generating the problem?

 

well, the anchored position is between the anchors and the pivot, so perhaps you had different settings?

 

I'm trying to move an image that is full screen and anchored to fully stretch.

 

I'm not sure what to suggest next...
